About this app

Choose or create a workout, press play, and let the app train you in this customizable workout log and timer.

This allows you to maximize your time in the gym while knowing exactly what time you’ll be finished with your workout with 321FIT's one of a kind ETA display.

FAQs

Can I listen to other music apps while using 321FIT?
You bet ya

Is there a rest timer?
The SEC/SET value represents both the time you will take to complete a set AND the time you allocate to rest. That way there is only one place you need to enter time.

I have ideas and feedback! Who can I tell???

love the overall design and themeing for this fitness app. some great additions would be: - 10 second warning sound like for boxing rounds, or a way to customize when warning time beeps start - text to voice for exercise name - create exercise groups in a workout to repeat as sets and not just one exercise with sets. - rest time between sets - a way to duplicate an exercise in a workout

Amazing! Simple,usable and concise. It is in it's early stages though. Would like somee more animations for new exercises added and maybe a more straight forward color picker,with some defaults to play around with. Nice job nonetheless!

Great app! Would love the option to share my workouts with others but no complaints at all here. Ad free. Simple but effective way to plan workouts. Love the style.
