The best male fertility apps, compared honestly.
Ten apps and programs for men who want to understand or improve their sperm health: what each actually does, what it measures or only tracks, what it costs, and who it suits, with a source for every fact.
Updated . Every app was re-checked on 7 October 2026 against its maker's own site or store listing, and 74 was added on 10 October; each product's source line gives the date it was checked.
The short version: testing apps (ExSeed, YO, Legacy) come with a physical test and give you a number. Habit apps (Motily, Juno, Finn, FertilityScore, Sperminal, 74) score the lifestyle factors research links to sperm quality and keep you consistent for the two to three months it takes new sperm to form. Couple apps like Flo for Partners are about her cycle and give you a supporting role. Most men end up wanting one from each of the first two groups; no single product does both well yet.
The best male fertility app for each need
There is no single best male fertility app: the right one depends on whether you want a test result or a daily habit. Picks by need, from the facts in the table below:
- Best with a home sperm test (UK and EU): ExSeed. A free app that runs a CE-marked home test, measuring volume, concentration, motility and total motile count; from £94.99 for two tests.
- Best with a home sperm test (US): YO. An FDA-cleared home test read through your phone's camera; $99.95 for three tests.
- Best for a full lab result (US): Legacy. Mail-in lab analysis with an online dashboard, included with the $295 and $495 kits.
- Best free habit tracker for iPhone: Motily (ours). A two-minute daily check-in on eight habits research links to sperm quality, a 74-day journey, the numbers from your semen analysis shown next to the WHO 2021 reference limits, and a page your partner can follow. Every feature is free during the launch period; most of the other habit trackers here charge a subscription.
- Best habit tracker on Android: Juno. The only habit tracker here with an Android app; subscription.
- Best for keeping your data on your phone: Sperminal or 74. Both store your logs on the device; both are subscriptions.
- Best for an AI coach: Finn. Ask questions alongside a daily score; needs iOS 26.
- Best for timing sex to her cycle: Flo for Partners. Her cycle, shared to your phone.
Many men use one from each of the first two groups: a test for a number, and a habit tracker for the two to three months before the retest.

Pounds are GBP and dollars are USD as listed by each maker; store prices vary by country. "Measures nothing" means the app has no test of its own, a description rather than a criticism.
Each product, fairly
Motily
Motily is a daily check-in: eight habits (sleep, alcohol and smoking, heat, exercise, nutrition, mood and stress, hydration, intercourse) logged in about two minutes, Today’s Motily points and a Motily score, a 74-day journey mapped to how sperm are made, streaks with Rest Days, a Wingman pairing with a friend, and a partner page she can open without installing anything. Enter the numbers from a semen analysis and each is shown against the WHO 6th edition reference limits, with a baseline-to-retest comparison after the cycle. The science page has the sources for every category.
Where it is weaker- It is not a test. Motily measures nothing; it tracks habits and shows the numbers you bring from a lab or a home kit next to the WHO reference limits.
- It is not medical advice or a medical device, and no regulator has assessed it. The score reflects your habits, not your fertility.
- iPhone only. No Android.
- Pricing is planned, not live: a free tier (check-in, scores, journey, first semen report, partner page, Wingman) and Premium at £8.99 a month or £54.99 a year (about £4.58 a month) for the score breakdown, longer trends and every report explained. Nothing is charged during the launch period and no card is collected.
ExSeed app
ExSeed is the most complete "test plus program" product here. The app runs the ExSeed home test (CE-IVD certified, marked CE 2797) and reports volume, concentration, motility and total motile sperm count in about 15 minutes, with a live view of the sample, an exportable report, and a stated manual review of every test by an ExSeed fertility expert. The lifestyle program (nutrition, stress, exercise, supplements, heat) is free and works without the device. Kits: 2 for £94.99, 5 for £149.99, 10 for £219.99, with free UK and EU shipping; the shop also lists Canada.
- No morphology, and the device is a rapid test rather than a full lab analysis.
- No FDA clearance is stated, and the shop does not list the US.
Sources: app page, kit page, App Store, checked 29 September 2026.
YO app (YO Home Sperm Test)
YO is the widest-shipped home device, and the one other brands resell (Proov's sperm test and Quest's at-home kit are YO devices). The app turns your phone camera into a microscope, records a video of the sample, and reports concentration, motility, progressive motility, motile sperm concentration and progressive motile sperm concentration in under 20 minutes, aligned to the WHO 6th edition. It is FDA-cleared; the original clearance was for a qualitative motile-sperm-concentration result at a 6 million per mL cut-off.
- No morphology, no volume, no DNA fragmentation. It is a screen, not a lab report.
- The app is only an interface for the device; there is no habit tracking or program.
Sources: kit page, App Store, FDA 510(k) K161493, checked 29 September 2026.
Legacy Sperm Insights
Legacy is a lab, not an app, but its Sperm Insights dashboard (March 2026) is the closest thing to tracking built on real lab numbers: a proprietary Sperm Score, age benchmarking against other Legacy clients, and tracking across kits. Analysis is done in CLIA-certified, New York CLEP-approved labs with results within 48 hours of receipt. The $145 Basic kit (April 2026) covers volume, count, concentration and motility but not the dashboard; Standard ($295) adds morphology and the dashboard, and Advanced ($495) adds DNA fragmentation.
- US only, and each data point costs a kit.
- No daily habit tracking; the dashboard tracks results, not behavior.
- The Sperm Score is proprietary, so it is not comparable with anyone else's number.
Sources: kit page (checked 29 September 2026), press release (16 April 2026), Femtech Insider (24 March 2026).
Juno
Juno is a straightforward habit tracker: log sleep, diet, stress and exercise, get personalized insights, and on the paid tier, progress charts and daily challenges. It is the only habit app in this group on Android, it comes from a registered company, and the Play listing was updated on 9 August 2026.
- The useful parts need a subscription, at $11.49 a month or $59.99 a year in the US.
- Small user base so far (the Play listing shows 100+ installs).
- Its latest update adds semen analysis upload and, in some regions, ordering at-home test kits in the app; we have not tested either.
Sources: Google Play, App Store, junofertility.app, checked 29 September 2026.
Finn: Sperm Health & Fertility
Finn (released 3 March 2026) is the app most like Motily in shape: a 0 to 100 "SpermScore", 74-day cycle tracking, streaks and daily habit logging. Two things set it apart: an AI coach you can ask questions, and uploading raw DNA data from a consumer genetics service for "genetic insights".
- Requires iOS 26, which rules out older iPhones.
- We found no published validation for the genetics feature, and an AI coach can sound more certain than the evidence is.
- New and from a single developer, so longevity is unproven; the same is true of Motily.
Source: App Store listing, checked 29 September 2026.
FertilityScore: Men's Health
FertilityScore gives two numbers, today's action and a cumulative 72-day trend, and its distinctive feature is a food database with the mechanism each food is thought to act through. Sleep, activity, stress and recovery are tracked daily, and anonymous accounts with EU-based encrypted storage are a good sign on privacy.
- Subscription prices are not shown on the listing text.
- No test integration or lab-report logging described.
- 72 days is close to the 74 used elsewhere; neither is exact.
Source: App Store listing, checked 29 September 2026.
Sperminal
Sperminal has the most interesting model of the habit apps: it treats the sperm your body is making as four overlapping batches and shows how today's sleep, exercise, alcohol, heat or illness lands on each. It keeps 90 days of history, supports partner sharing, and stores everything on the device: no accounts, no cloud, no ads. It says plainly that it is an educational tool, not a medical device.
- No backup or sync, by design; a new phone means starting again.
- Released April 2026, so it is early.
- No semen analysis logging described.
Source: App Store listing, checked 29 September 2026.
74: Male Fertility Tracker
74 is named after the same 74-day cycle Motily is built around. It has a quick daily routine check-in (sleep, exercise, hydration, food, alcohol, coffee, smoking, supplements, heat, illness and medication changes) with a routine score that shows which answers fed it, a timeline of the current cycle, a semen analysis log that keeps each lab's own reference ranges, one-off AI questions, and fertile-window planning with a partner. Data is kept on the phone, and it can import selected data from Apple Health.
- Without a subscription you can only see the app overview; tracking needs the paid tier.
- New, with too few UK ratings for the App Store to show an average (10 October 2026).
- From a single developer, so longevity is unproven; the same is true of Motily.
Source: App Store listing, checked 10 October 2026.
Flo for Partners
Flo for Partners lets a woman using Flo share her cycle with her partner's phone: where she is in the cycle, when she is likely ovulating, symptoms, and articles on how to be useful. If your only question is when to have sex, this is the most direct answer at no extra cost. Other cycle apps (Ovia, Glow, Premom, Fertility Friend, Kindara) have partner sharing to varying degrees; we have not verified their current features and do not list them.
- Nothing about you is tracked. It is her app, shared.
- Some Flo content sits inside Flo Premium.
- Motily's partner page works the other way round (she sees your progress), and the two can coexist.

What we left out, and why
Mojo (UK, mail-in AI analysis) still has a website, but a UK reseller reports it ceased trading in summer 2025 and we could not verify a live price or checkout. Bird&Be, Fellow, Ro, SpermCheck, Proov and Labcorp OnDemand sell tests without a tracking app; they are on the at-home sperm tests comparison. Tilly is a mental-health app for couples in fertility treatment, not a tracker. Batch was described in a May 2026 Men's Journal piece as a $149-a-year app with three sperm tests a year and Oura sync, but the site it names is a donor-matching platform and we could not verify the app from its own pages. Bevel turned up nothing verifiable. Anything we could not confirm from the maker's own site or store listing is out.
How to choose, by situation
Just starting to try
You probably do not need a test yet. Pick a habit app you will actually open daily and give it a full 74-day cycle, because sperm made today are the ones in play in three months. Add Flo for Partners if timing is the open question. After a year without a pregnancy (six months if your partner is 35 or over), see a doctor; that is a normal step, not a verdict.
You have a result to improve
You want a retest about three months out and something that keeps you honest in between. Motily is built for this loop (baseline report in, 74 days of check-ins, retest window, before-and-after) and shows the numbers next to the WHO limits. ExSeed does the same with its own device at each end, simpler in the UK or EU if you do not need morphology. Treatment decisions belong with your clinician.
You want a lab number
Use a lab: Legacy, Fellow or Ro in the US, Malebox in the UK, or an NHS semen analysis through your GP. All of them are in the at-home test comparison with prices and what each measures. Home devices (YO, ExSeed, Bird&Be) screen count and motility but not morphology. Motily then shows the report's numbers next to the WHO 6th edition limits and tracks the change between reports; Legacy's dashboard does the same for its own kits.
You want a daily habit
All six habit apps do the basics. The differences are platform (Juno for Android), privacy (Sperminal and 74 keep your logs on the phone), extras (Finn's AI coach, FertilityScore's food database) and what surrounds the habit (Motily's partner page, Wingman and lab-report interpretation). Try the free tiers; the one you still open on day 40 is the right one.
Questions people ask
What is the best male fertility app?
It depends on what you need. For a home sperm test, ExSeed (UK and EU) and YO (US) pair a free app with a test kit. For a full lab result in the US, Legacy has a dashboard. For a daily habit tracker, Motily is free on iPhone during its launch period (we make Motily), Juno is the one with an Android app, and Finn, FertilityScore, Sperminal and 74 are subscription iPhone apps. Many men use a test and a habit tracker together. Picks by need.
Can an app improve male fertility?
No app has been shown to improve fertility on its own. Habit apps track the lifestyle factors research links to semen quality, such as sleep, alcohol, smoking, heat and weight, and help you stay consistent for the roughly 74 days it takes to make new sperm. Testing apps measure; they do not change the result. After a year of trying (six months if your partner is 35 or over), see a doctor.
Can an app measure my sperm count?
Only if it comes with a physical test. The ExSeed and YO apps analyze a sample through a device on your phone, and Legacy's dashboard shows mail-in lab results. Motily, Juno, Finn, FertilityScore, Sperminal and 74 are habit trackers: they score lifestyle factors linked to sperm health (Motily shows the numbers from a lab report next to the WHO 2021 reference limits, and Juno and 74 let you log them), but none measures anything itself.
Which male fertility app is free?
As of 10 October 2026: the ExSeed app is free and its lifestyle content works without the device, though testing needs the kit (from £94.99 for two tests). The YO app is free but needs the YO device ($99.95 for three tests). Motily is free during its launch period, Premium included, with a free tier planned after it. Juno ($11.49 a month or $59.99 a year in the US), Finn, FertilityScore, Sperminal and 74 use subscriptions.
Do any of these apps work on Android?
ExSeed, YO and Juno have Android and iOS apps. Flo for Partners is on both. Finn, FertilityScore, Sperminal, 74 and Motily are Apple-only, with no Android app, as of 10 October 2026; Motily's partner page is a website, so a partner on Android can use that part.
How long does it take for lifestyle changes to show in a sperm test?
Roughly two to three months. Sperm take about 74 days to develop plus one to two weeks to mature, so a test a week into a new routine mostly reflects the old one. That is why Motily, Finn, FertilityScore, Sperminal and 74 are built around a 72 to 74 day cycle, and why a before-and-after test is best spaced about three months apart. The FAQ has the studies.
Is a fertility score from an app the same as being fertile?
No. Every score here, including Motily's, is an estimate built from what you log: habits, not fertility. A semen analysis measures sperm, and only a clinician can interpret it in the context of your health and your partner's. After a year of trying (six months if your partner is 35 or over), see a doctor regardless of any app.

Correction, 29 September 2026. Two rows were out of date. The YO app now needs iOS 15 or later, not iOS 11, and its Play listing no longer states an Android minimum. Juno's subscription prices are now shown on its store listings ($11.49 a month or $59.99 a year in the US, £9.99 or £59.99 in the UK), so "price not shown" has been replaced with the figures.
Correction, 8 October 2026. Re-checked every app on 7 October 2026: Legacy's dashboard comes with its $295 and $495 kits, not the $145 one; Juno now takes semen analysis uploads; Sperminal is now a subscription; Finn and FertilityScore also run on iPad; Batch includes three tests a year, not four.
Update, 10 October 2026. Added 74 (Male Fertility Tracker), checked on its App Store listing today, plus picks by need and two questions. Motily's results feature is now described as showing your numbers next to the WHO 2021 reference limits. Fixed the page's structured data, which still described Sperminal as free with a one-off unlock; it is a subscription, as the page already said.
