I'm sure it's a good app if you want to control your miners, but the UI is pretty bad. It is just a bunch of very small numbers. No graphs or charts or visually interesting elements at all. It is impossible to pick out the important info. It is such a missed opportunity for a beautiful UI.

Hey Scott — thanks for the feedback. Please make sure you’re on the latest HashWatcher — there are several charts and visual elements that surface the important mining data. If you’re already current and still finding it hard to see what matters, tell us what you look at most day-to-day and we’ll keep improving hierarchy. — Gabe

Great application and have come to depend on it. the updates have been often and substantial. My only complaint is with Android's update approval process, which has been woefully ineffective in staying up to date on updates.

Notification spam and degradation of app quality. I'd reccomend staying on an old version to avoid notifications 5x a day or whatever they add next or ask your favorite ai to make a monitor for you

Sorry about the frustrations. Notifications are never sent that frequently and are opt-in only, so you shouldn’t get them that often. If something still feels off on quality, email us and we’ll be happy to look into it. Thanks
