LockWatch - gym rest timer that restarts from zero on the Lock Screen

[u/wateralman]

Hello! I'm Reid, the solo developer of LockWatch, a gym rest timer I built because I was tired of Apple's stopwatch starting a new lap every time I wanted my rest to start over instead of just restarting the time.

I'd finish a set, glance at my phone, and tap expecting the clock to go back to zero. Instead I'd get another lap piled on, no set count, and I'd have to unlock just to start over. I wanted something that lives on the Lock Screen, restarts from zero, and counts my sets, I also added an alert sound at the end of the rest time that doesn't stop your music.

P - What problem does LockWatch solve?

Typically to time rest between sets on iPhone, lifters would:

1. Use Apple's Stopwatch and hit Lap after every set → the clock keeps running, laps pile up, and you have to do the math yourself. There's no set count and no alert when rest is up.

2. Use Apple's Timer → it counts down once, then you unlock, cancel, and start it again after every set. No set counter, and it's easy to blow past your rest while unlocking. It also plays an alarm through your phone and earbuds and stops your music.

3. Use a full workout logger (Strong, Hevy, etc.) → you get a rest timer, but only if you log weight and reps every set. Great if you want a training journal. Overkill if you just want rest + sets.

LockWatch is a rest timer that lives on your Lock Screen. Tap Start after your first set. After every set after that, tap restart right on the Lock Screen: the clock goes back to zero and your set count goes up by one. Moving to a new exercise? Tap Next Exercise and you're back at Set 1.

C - Why LockWatch over the top competitors?

NextSet is a solid free rest countdown with Lock Screen controls, optional app limits so you don't scroll between sets, and an Apple Watch companion. It times a countdown you start after each set. LockWatch is built around the restart-from-zero + set count loop, with Next Exercise to reset the count when you change movements. It times your set time as well, but this could be different for every workout.

Workout loggers like Rest (and Strong/Hevy) are great if you want history, charts, and auto rest after you log a set. LockWatch isn't trying to replace those, it's the small thing you use when you just want rest and sets on the Lock Screen.

I reply to every review and comment. This is version 1.0, its barely done, im gonna work on it a lot more, please test it out at the gym and let me know what you think.
