Hourglass vs PlugBrain
Side-by-side comparison of two open source alternatives
Hourglass
A simple application that can be used to start a timer from one second to one hour. The app can then be closed or left open, while a status bar notification reminds you that you have a timer in progress. Upon reaching 00:00, an audible bell as well as a short vibration and visual pop-up will indicate that your timer has ended. Great for reminding yourself to do something, or for use while playing games that require timers!
PlugBrain
PlugBrain is an app that encourages regular breaks from distracting apps by blocking access at scheduled intervals. To regain access, you’ll need to solve a math challenge that adjusts in difficulty: the more frequently you use the apps, the harder the challenges become, but the longer you stay away, the easier they get. **Features** - No ads - No internet required - Blocks distracting apps - Unblock apps by solving math challenges - Difficulty increases with frequent use, decreases with focus **How to use** - Grant all required permissions - Select distracting apps - Choose your focus interval - Stay focused ;)
