Lockout: Workout Timer
Stop scrolling. Start lifting.

Stop scrolling. Start lifting.
Lockout is the workout timer that blocks every other app on your phone while you train. Instagram, TikTok, Twitter, all of it: until your last set is done.
TOTAL LOCKOUT MODE
Tap one button. Your phone becomes a single-purpose tool — just Lockout, your music, and the system Phone for emergencies. Everything else is shielded for the entire workout. When you finish, the lock drops automatically. No willpower required. No "just five more minutes." The bench you've been hogging is finally free.
LOUD INTERRUPTIONS
Run over a rest period and Lockout interrupts you instantly. Pick a siren, an air horn, a klaxon — or have it switch your music aggressively. It works because you don't want it to.
YOUR MUSIC, YOUR SERVICE
Apple Music or Spotify Premium. Lockout auto-plays when you start, ducks for voice cues, and pauses or skips your music when an interruption fires. Pick your hype track from inside the app.
COACH IN YOUR EAR
Auto mode counts you down with 3-2-1 voice cues and announces "next set" or "next exercise" so you can train heads-up, hands-down. Male or female voice, your call.
EVERY PR CELEBRATED
Log a set in seconds — weight, reps, plate calculator pre-loaded. Beat your previous best and the trophy lands automatically. Same lift, more weight. Same weight, more reps. Lockout sees it and celebrates it.
PROGRESS YOU CAN SEE
Every PR moment graphed by date. The y-axis tightens around your real range so a 250 → 315 climb reads as the win it actually is.
KEEP THE STREAK
Cadence dots on the home screen. One-tap resume of your last routine. Color-coded category days — legs, chest, arms — so the calendar tells your story at a glance.
MOTION FAILSAFE
Forgot to stop the timer? If your phone sits still mid-rest for too long, Lockout asks you and trims the time you weren't actually working.
WORKS WITH YOUR WRIST
Apple Watch companion with one-tap set ending. AirPods out? Music pauses automatically. Lock Screen and Dynamic Island show your active workout so you don't have to unlock to check the clock.
PRIVATE BY DESIGN
Your workouts live in your iCloud. No accounts. No servers. No ads. We don't track you. We don't sell your data. We don't have your data.
LOCKOUT IS A SUBSCRIPTION
No tiers. No upsells. No "premium features unlocked." You get everything above, every update we ship, and an app that respects your training time. Try it free, keep it if you keep lifting.
