Foto Timer
APK
Foto Timer for Android is a free, open source app that can count and beep. It helps with repeating tasks, such as at the gym. People also use it for developing analogue film, or for meditating. Foto Timer is working with "processes", which define how Foto Timer counts, and how often it beeps. Processes can also be "chained" together, meaning that a process can automatically launch another. There is almost no limit to how complex your timers can be. If you want to see what Foto Timer looks like, take a look at the manual. If you prefer a "how to" approach, learn how to use Foto Timer for Tabata exercises. Foto Timer contains absolutely no AI whatsoever.

Githo
APK
Get Into The Habit Of… Acquiring habits that stick can be difficult. Githo helps you by letting you gradually advance, instead of going from 0 to 100%. This principle borrows ideas from exposure therapy. Define levels of your final habit, going from easy to hard. Then start with the first one. Level up by consistently succeeding. If a level is too difficult (= if success isn't consistent), repeat the previous one. Such a gradual acquisition reduces the physical/mental strain and helps you create a routine long before arriving at the final habit. Example of a Habit-Plan: Final Habit: Go jogging every morning Levels: Every morning... * Week 1: Just step outside on the street, then return home. * Week 2: Take a walk around your house/building. * Week 3: Take a walk spanning 3-5 buildings. * Week 4: Take a longer walk and add short jogging-segments into the mix. * Week 5: Go jogging. Well done. Permissions Permissions are only used to display notifications.

HabsGleich
APK
HabsGleich enables you to note small changes of your mind's performance without referring to non-personal standard tests or uploading sensitive data to third party servers. To this end you collect adventures in the diary on a rougly daily basis. The choice and language of the adventures should be consistent over time and the time between noting two subsequent adventures should not vary too much from one day. After some time the app begins to choose adventures from the diary for mind testing. This choice is adaptive to your mind performance in such a way that you always can expect to have more positive than negative results. The test results are amalgated into a single number, the "mind index". Its value is roughly the number of days you still remember your adventures rather well after. The temporal graph of this mind index is displayed on the statistics page of the app. The diary can be used to search, edit and remove adventures. Some screenshots display quotes by Henry David Thoreau.
