Imagine an app that suggests simple activities based on analysis of your behaviour, e.g. how long and how well you sleep, how active you are or where you prefer to hang out. For example - if you hate running so much you'd rather wait for the next bus instead of sprinting 50 meters to get the one approaching the station, that app would never suggest you to run a half marathon (or even a 16th for that matter).
Well, such an app exists and it's called Aidlab.

In order to get credit for succeeding, you need to exceed a minimal threshold for the particular activity. There is no upper limit, so don't stop! Not only your health benefits, but you can also place yourself in a record book of the given location, where the 3 best scores of each year land.
Please, don't hesitate to email them to contact@aidlab.com. We promise to check each suggestion individually and get back to you.
