7 startups that want to improve your mental health

Aloe Bud reminds you to take care of yourself.

The free app sends alerts to drink water, move, breathe and take a break. It can also prompt you to take medication at a certain time.

If push notifications aren't your thing, you can access exercises within the app. For example, the "Breathe" activity gives brief instructions to help you relax: "Breathe in for 4, hold for 4 and exhale for 4. This too shall pass."

Users can pay a one-time fee of $4.99 to unlock additional features, such as more reminders and the ability to write custom messages.

The app, which launched in April, doesn't require you to sign up with a name or email address.
