Great Timer

The best tabata/interval timer for iOS. Great design, fast and straightforward. The sounds are simple and polished without being stupid.

I'd absolutely love it if the designer were able to add a super simple, super clean, totally optional way to save a few routines as presets. I love the clean, simple interface; but I find myself frequently fiddling with the times throughout my workout, which over the course of months, begins to feel a little frustrating. Wish there was some simple, elegant way to add this without compromising the clean interface, because it would add a bunch of functionality.

Aside from this common complaint, the app is great. Five stars!

Exceptional support!

I have been using and loving Bit Timer for years. The user interface is elegantly simple and the app does exactly what I want it to do without being bloated by features I don’t care about.

But now, I’m here to talk about Peiter’s fast and effective response to a display problem I suddenly began having a few weeks ago. Short story: I emailed Peiter and described the problem; he emailed me back with a couple of questions; and in no time he had traced the problem to a bold-text IOS update. And then he fixed the problem!! If only everybody else in my life were like Peiter!!

Updates missed some basics

I have loved this app for years and use it for AMRAP time as well as intervals. Since the update the max ‘work’ time has lowered to 6:00minutes. I can no longer do 12m workouts without making a work-around. Minor inconvenience. What is the most upsetting with the update is I can’t leave the app open and watch time any longer because it significantly reduces the music volume. Really disappointing. It’s not clear if a subscription fixes the volume issue like it would the work time limits. I can’t imagine needing 60 repeats 😂 but they added that in.

Thanks for the feedback and long time support!
Re: reduced audio volume from other apps - we've tracked the issue down and expect to ship an update shortly to alleviate the problem.

UPDATE: v3.0.2 went live today and it should address the audio volume issue. If not, please let us know so we gan figure out whats going on.
