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.

Don’t waste your time putting in individual exercises as you’ll only pay attention to the beeps and checking screen sporadically for how long is left. ### 5/5 — Spinning Instructors can count on this app *2020-01-23, version 2.4* Great app, simple and straight forward. You add rounds, name them, set repeats and your done!! Of course you can do standard HIIT but also correct for when your instructing Pyramid sets where rounds are variable with set recovery times. To remove ads, cost is very fair. Just recommended on instructors VA RIDE group!! ### 1/5 — Garbage. *2019-05-11, version 2.4* Don’t waste your time, if you make more workouts than it has on the screen it doesn’t scroll down. And just send you ads. ### 4/5 — Great app *2019-04-11, version 2.4* This is great app. Exactly what I’ve been looking for. I can make up my own workouts and put times and rest times in. Even better I can edit the workouts. Needs compatibility with Apple Watch and health app and ability to change sounds. Apart from that perfect. Since recent update the exercises don’t scroll properly. ### 5/5 — Easy and customizable *2017-12-29* Very easy to use and you can customize your timer to each of your workouts! Very handy! ### 5/5 — Best WOD Timer App Out there *2017-03-05* This is the best WOD Timer out there and it is free. Wow! ### 4/5 — Awesome app.. allows me to input my Zen Dude Fitness Workouts *2017-02-17* I love this app because it start you off on a blank slate and allows you to build the workout with exercise time and break. Only thing I don't like about this app is when you start a workout the volume of your music gets cut dramatically. Please change the feature .. I like that you have an independent volume for the bell and 5 second left timer. Just change the volume cutting ### 3/5 — It's does EXACTLY what it says, but no more. *2016-10-15* I have a lot of workout apps. I expected a little more from this one. It does exactly as advertised, and that's it. I entered in my workout and I like the easy interface. Super simple and un complicated. Here are the improvements I'd like to see....1) stop pausing if I switch screens or my phone auto locks 2) allow me to play music "over" the workout 3) I paid the 99 cents for as free - I have to "restore purchase" every time I use the app. Those improvements alone would get this app a 5-star rating cuz it's exactly what I was looking for ### 5/5 — Great workout/training app *2016-09-02* Simple and useful -- perfect for everyday workouts. Plus you can play music now!!! ### 5/5 — Helpful app *2016-03-08, version 1.5* This app can massively help count time when I am doing indoor exercise. ## Frequently asked questions about TimedTrainer ### What does TimedTrainer do?
