Offline-first · No account required

Your round stays sacred.

140+ presets, custom workouts, multi-week programs, and automated field tests — Beep, PACER, Yo-Yo, 30–15 IFT, Bronco — with local athlete rosters, squad mode, all on your phone, with zero ads during workouts and no sign-in to get started.

Live interval timer during a work round

No ads mid-workout.
Not fewer — none.

While the timer runs or a beep test is live, the app is silent about money. Optional support comes after — a tip jar or ads you choose to enable in Settings. The core timer stays free.

Everything you need to train — on device

v1 is built for athletes who want a focused timer, not a social network. Install, pick a preset or build your own, and go.

Straight answers

Is the app really free?

Yes. The interval timer, presets, and fitness tests are free — no subscription. If you love it, you can leave an optional coffee tip in Settings.

Will ads interrupt my workout?

Never. No banners or full-screen ads while the timer runs or during a beep test. Optional support ads appear only after you finish — and only if you turn them on.

Can I run a beep test with just my phone?

Yes. The app beeps every shuttle for Beep, PACER, Yo-Yo, Endurance, 30–15 IFT, and Bronco. It tracks stages, scores, age norms, squad mode, and lets you share results.

Do I need an account?

No. v1 works fully offline — presets, custom workouts, programs, and history stay on your device. Sign-in and cloud backup are on the roadmap.

What is the tip jar?

A one-time optional tip through Google Play — a thank-you for development. The core timer stays free. Hosted AI Coach perks will apply when that feature ships.

What about my data?

Everything stays on your phone at launch — no account required. Analytics and ads are opt-in. Cloud sync and clubs are coming later, also opt-in. Read our privacy policy.

Train with intention.

140+ presets. Custom workouts. Fully offline. Zero ads during workouts.
