I suddenly have a high-pitched voice notifier. really annoying and can barely hear. can't figure out how to change it. Help! This is a GREAT timer. my Garmin broke and have been using it for my interval workouts on my bike. I am also now using it for meditation sessions. Try to get the hang of the options it offers to make personalizing workouts faster. Looking forward to updates. I do have some suggestions such as combining different workouts to roll from one to the other. Solid App.

Was looking for a replacement for a guided task app on my old phone that doesn't alarm reliably on this one. This app is just about perfect and very customizable! My phone aggressively memory manages no matter how many things I disable, but the scheduler even sort of worked! Just gotta figure out how to keep it working consistently (and hopefully it's not one of those handful of apps that needs the trick of a widget...).

Does most of what I need it do (intervals for exercise and studying), but the tutorials seemed like too much info all at once so I skipped them. It's worked out so far. I just wish there were more flexibility for notification during a routine step rather than (halftime, and countdown). I just break it down further, as needed.

Thanks for your feedback. It's impressive that you can figure out how the app works without tutorials. As for more flexibility for notification, adding many detailed settings to behavior is not only complicated but also error-prone. So I decided to only add common behavior(half, count, etc) and leave more complex jobs to the combination of steps.
