I tried Lift out, and though it does seem that there it has a place for a some audiences, unfortunately I am not one of them. A few gripes (I understand that Lift.do just released, so some of these concerns may be premature)
1. It's binary - in that you workout or you don't, you sleep 8 hours or you don't. My needs are a bit different - I want to be able to log how much I do of something. For e.g. drinking water - I want to track that I drink enough water. The only solution I had was to use a habit titled "Drink 8 glasses of water" - For me, that doesn't work (I have to keep count of how many glasses of water I drank in the day). I want to "check in" every time I do something - if it's a workout, then a check-in a day suffices - if I want to sleep 8 hours but only manage 7, well, there's no way to manage that.
2. Export functionality - I want to export my data out of Lift.
The only app I have come across that let's me do this right is Dayta (free for iOS) - Unfortunately it has not seen any movement lately but it's very close to what I need. What Dayta does not get right is
1. No defaults. If I don't make an entry for a day, it does not assume 0
2. Only numeric data - For e.g Workout (in my case) is either a 1 or a 0 - It would be nice to have a Boolean switch
3. Dayta exports nicely - to CSV via email. I export on a month to month basis which means I usually go back in and have to delete the entries for the past month. Dayta gives you no way to "bulk delete" - You have to swipe each entry and delete.
4. Lift.do gets this right - Notes on a check-in. After a workout I want to know how I felt. Perhaps I did not hit the 6 mile marker - Was I sick? Or injured? Or just being lazy?
Along with all this it would be nice to
1. Plot a habit that has a scheduled interval. For e.g workout every other day (Perhaps a reminder or a gentle nudge)
2. Identify habits you aren't doing so well at.
I am currently using a mix of apps to track my progress - Momento (Journal app), Dayta, and Fitocracy (to log workouts in detail).
FWIW, Lift.do is a gorgeous app. I really like the way it looks, feels and works. The social element is a nice touch too.
Good luck guys. I am keeping an eye on you - Perhaps soon I will change my mind.
