Nightmare

Tryed for ages to sign up ,gave up .was sad Might try another day when I have more time .

Does what I need

I wanted something simple for tracking. I like that this helps Hopkins with research. It is so simple that less than a few minutes each day is all I need to track my timing for eating and sleeping. I can look back over my entries in the calendar, so I am not bothered by the lack of data aggregation that another reviewer mentions.

Adequate

It’s a fairly simple, bare-bones app which keeps track of eating times (and very approximate amounts) and sleeping times. The data are sent to JHU for study, and cannot be examined in aggregate by the user in any sort of critical way.

The app is slightly buggy (crashes occasionally) and doesn’t keep accurate track of streaks or leaderboard data, which will depress any competitive incentive to log in and improve standing.
