FAQs
Q: Is it a subscription thing?
A: Nope. We keep it simple: enjoy the free version with essential features, or make a one-time, small payment for the full version. No recurring charges, just support towards your personal best.

Q: What do I get if I buy it?
A: The full version unlocks all the goodness. You'll get unlimited saved timers (instead of just 3), the ability to enable hundredths of a second input & display (good for beep tests etc.), plus import & share options (& we'll install many of the timers available on the resources page of the website (yes; this does include the beep test)). It's everything in the free version, but super charged.

Q: What’s a Reaction session?
A: Reaction sessions spice things up with random interval calls. They're great for sharpening your reflexes in martial arts or boxing, or for creating dynamic workouts for rehab; it can be like those fancy light reaction training tools, but using just your phone & some everyday objects. Again, it's just like having a personal coach calling things out, only with this session, you don't know what they're going to call, or for how long.

Q: Is there a free trial?
A: There isn't a free trail, but the free version (without ads) lets you test drive the core features.

Q: How do I share things?
A: On the Home screen or in a folder, hit the edit button in the bottom left. Select the workout(s) you want to share, tap the share button in the top right, & voila!

Q: How do I import sessions?
A: Easy peasy...Start creating a new workout, scroll to the bottom, & tap ‘Import from CSV’. Just make sure your .csv file is formatted correctly before importing.
