About TimedTrainer: Interval Timer
Build a workout in seconds. Hit start. Train. TimedTrainer is an interval timer with one job: telling you when to move. No more staring at the clock on the wall, no more fiddling with your phone between rounds. No accounts. No onboarding tour. No preset plans you'll never use. HOW IT WORKS 1. Create a workout and name it. 2. Add rounds. Each round has a name, a work time, and an optional rest after it. 3. Choose how many times to repeat the whole list, and go. That's the entire app. A core workout takes about twenty seconds to build: - Crunches, 1:00 - Plank, 0:30, then rest 0:05, because planks hurt - Bicycle kicks, 1:00 Repeat 5 times. Start. WHAT'S IN IT - Unlimited rounds, and 1 to 100 sets of the whole list - Work and rest per round, from preset chips or a typed h:m:s keypad - Reorder, duplicate, and delete rounds while you build - A Get Ready countdown before the first round - Clear audio cues: a ding into each round, beeps counting down the last seconds, a buzzer at the end, a chime at the finish - Four sound themes: Classic, Arcade, Fight Night, and Zen - Pick how many seconds of beeps you want before a round ends - Haptic taps at every work period, rest, and finish - Keeps timing with the screen locked, the app in the background, and your music playing - Pauses itself for a phone call, for Siri, or when your headphones drop out, then picks up exactly where you stopped - Keeps the screen awake during a workout, unless you'd rather it didn't - A day streak, and this week's training at a glance on the home screen - A summary after every workout with total time and working time. Add a photo and share the card. GREAT FOR Boxing - HIIT - CrossFit and WODs - Tabata - EMOM and AMRAP - Circuits - Weight lifting - Sprints and Fartlek - Stretching and mobility - Martial arts and MMA drills - Wrestling - Jump rope - Rehab sets PRICE TimedTrainer is free, with ads. One $0.99 purchase removes them permanently. Everything else is unlocked from the start: no subscription, no paywalled rounds, no limits.
