Stack 2.0 is a Chrome Extension which enables you to rapidly take key-value based notes within a new tab.

Check is an ephemeral to-do list for iOS. It provides:

- tasks are removed after a certain duration

- you can define the duration for tasks in hours (default is 24 hours).

- The "task graveyard": Tasks which are not finished within the duration are killed and can be found in the graveyard. You can easily revive them and try them again later.

Uptime is a super simple Pomodoro / interval timer to stay productive.
