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???
