Feature rich, but unintuitive UX design.

1. Overall great app, I use it almost everyday.

2. The UX for copying, pasting, editing, creating folders, rearranging things etc is a bit unintuitive. But once you get the hang of it it’s not too bad.

3. If I could have my music volume stay constant when the timer labels are being read out loud that would be nice. I don’t need the music volume to be constantly going up and down. For this reason alone I never use the music feature, and I play music on a separate device for my timers.

The flexibility and reliability that you get makes the app well worth every penny.
I don’t think there’s anything else on the App Store as easy and straightforward to use yet so flexible and customisable as seconds pro.
I find myself just randomly making up workouts when I’m bored because it’s just that easy to do.
As a former boxer I structure my workouts on a round system, I just wish I had this app when I was still active. It keeps the time and lets me know what exercise is coming up next.
If you do a lot of intervals I highly recommend this app.

Changed my life

I was looking for a solution to programming workouts and this has proven itself to be the best value. As a result I’ve been more motivated to do the workouts and have now lost 30kg and gained muscle and strength as a result of diet and exercise and this app has been integral to that. It caters to whatever timing arrangements you can think of. My only wish is that I could more easily share and export my workouts to my sister who I also purchased the app for. Otherwise it’s great. Best interval timer app out there.
