Some news, a few numbers, and a real ask at the end.
The app passed 100,000 downloads
When we launched the 30-15 IFT mobile app, the idea was simple: put the test in every pocket, in every gym, on every pitch. Six years later, it has been downloaded more than 100,000 times.
That number belongs to you. Every coach, every athlete, every sport scientist who pressed play before a session helped take this test from a single PDF and a CD-ROM to something used on every continent.
What we learned from the people who wrote in
Since 2021, 1,503 of you took the time to send feedback through the in-app form. We read every single message. The picture that emerged is striking:
- 3 languages spoken: Spanish (47%), English (37%), French (17%). The Spanish-speaking world has owned this test more than any other.
- 120 different sports represented. Yes, 120. Football leads (60% of feedback) but the test has clearly travelled far beyond team sports: handball, basketball, hockey, rugby, tennis, futsal, lacrosse, taekwondo, judo, AFL, even ultimate frisbee and CrossFit.
- 1,154 unique clubs, federations and structures named. From FC Bayern Munich, FC Barcelona, Olympique Lyonnais, Sporting CP and Liverpool FC, to the Brazil Olympic Committee, the Spanish Basketball Federation, the Bahrain U20 national team, and hundreds of academies, universities and amateur clubs nobody outside their town has heard of. That mix is exactly what makes this special.
- 57% Android, 43% iOS, fairly stable across the years.
- 4.5 years of continuous feedback, from November 2021 to last week.
The mobile app is closing. Here is what comes next.
Keeping the app alive on two stores, dozens of phone models, and constantly changing OS rules has become unmanageable. The honest truth:
- Android version: already retired. Too many devices, too many OS versions, too few hours.
- iOS version: still works, but will be removed in the coming months.
- The mobile app, as a product, is finished.
But the test is not going anywhere. We have built something better, simpler, and free:
The Sound Files page
Everything the app did — beeps, voice cues, all four versions (40 m, 28 m, ice, 400 m track), in English, French and Spanish — is now a free web page. No install, no update, no store. Open the page, press play, run the test.
👉 https://30-15ift.com/sound-files/
Bookmark it on your phone, project it through the gym speakers, share the link with your squad. That is it.
And now, the ask. A real one.
For 25 years, coaches have been running the 30-15 IFT and asking the same question: is my player’s VIFT good? Good compared to what? To whom?
We finally have an answer in progress. The new Benchmarks page lets you compare any athlete or squad against real results from clubs, federations and academies around the world. Pick your test version, filter by sport, sex, age, competition level and playing position, and see the percentiles your athletes need to beat.
👉 https://30-15ift.com/benchmarks/
Here is the problem. 100,000 of you downloaded the app. The benchmark database holds only 3,000 results. That is 3%. Ninety-seven percent of the data the 30-15 IFT has ever produced is sitting on someone’s laptop, in someone’s drawer, in a PDF report nobody will ever open again.
Let me say this directly: the test gave you something. Now is the moment to give back.
Every season, every coach reading this runs the 30-15 IFT on a squad. 15 athletes. 20. 30. A youth academy might test 200 players a year. If even 5% of the people who downloaded the app shared one round of testing, we would have more than 60,000 results in the database. That is the biggest VIFT reference dataset ever assembled, by a wide margin. It would settle questions that have been open in our field for two decades.
Right now it is 3%. We can do better.
What to send: sport, club, sex, age category, position if relevant, VIFT. That is it. No names, no identifying information. The form anonymises everything before it enters the database.
How long it takes: two minutes. Literally. Open the form on the Benchmarks page, paste your values, submit.
Why it matters: the only reason coaches in 2026 can compare a U17 academy player against a senior pro is because somebody, somewhere, shared their numbers. The benchmark is only as honest as the community that builds it. If you have ever used a VIFT cut-off, a reference value, or a « good for this level » number to make a decision about an athlete, somebody gave that to you for free. Pay it forward.

Thank you
To everyone who downloaded, ran, tested, debugged, emailed and shared: the app served you, you served the test. Same deal continues — just on a better platform, with a sharper purpose.
Now go open that old spreadsheet from last pre-season. You know the one. Send the numbers.
See you on the line.
