Update is Awful

This app worked wonders for our business. Since the update, we have had nothing but trouble and failed clocks. We continue to have issues daily and are considering changing completely.

Launch video

That launch video is annoying! Who watches that??? And they want you to pay to turn it off. This is awful.

Perfect App!

I absolutely love this app! I’ve been using it for a few years and they’ve made some pretty awesome updates!

Overall great, but lacks visual cues

Great options for customization. Could benefit from the addition of visual cues (e.g., screen flashing, or something else noticeable without staring at the screen) to signal interval changes, as an alternative to strictly auditory cues. This would help the hearing impaired and those of us using the app in places where sounds are problematic.
