Dear Future Self is a unique Android app developed by staticfree.info that allows you to send messages to your future self. With this app, you can also share messages to yourself from various social media platforms like Twitter.

One of the most interesting features of the app is its experimental timeline user interface. You can pan and zoom through time by dragging left, right, up, and down. The app is free to use and is licensed under GPLv3. It's important to note that since the app is still in the experimental stage, it may be a little rough around the edges.

In summary, if you're looking for a fun and unique way to communicate with your future self, Dear Future Self is definitely worth checking out.
