I’ve been using Lift this year to try to encourage the establishment of good habits. It’s more of a social networking approach to habits. You sign in to specific habits, and others who are trying to do the same habit (30-day plank challenge, for example, or Establish a writing habit) can see your activity and comment on it. You can also comment on your own activities (but not the lack thereof, as far as I can tell — you can’t say why you didn’t exercise on a given day until the next day that you do exercise). And if you link your Facebook or Twitter profiles, you can connect with people you’re already friends with to encourage each other.
The site works on the basic practices of accountability to others (your friends and followers) and of not breaking the chain. Fairly simple and tried-and-true methods. Because of the way it’s set up, though, every day has to be accounted for — if you’re doing an exercise program and it has rest days built into it, those days have to be set into the program from the beginning — which is fine if you’re doing something like working for 6 weeks to get ready for a 5k run, but seems rather less practical if you want something to remind you to run three days a week ad infinitum. For me, Lift seems best geared to things you want to do every day (drink a glass of water before dinner) or something that you’re only working on for a short time.
It excels at training for new habits — for things like developing a specific habit, where you’re working up to it, there’s often coaching involved that helps break down the task into steps and lets you look at the motivation and reason every step along the way. For example, the writing one I did (Develop a Writing Habit) starts with knowing why you want to write, then creating a goal, with various motivational posts along the way.
When you finish a habit’s run, whether it’s 30 days or 90 or whatever, it automatically repeats. Again, that can be useful if you’re just trying to remind yourself to keep doing something on a daily basis. For the writing, though, it felt kind of silly to get the same motivational talks each time.
Overall, I’d say if you like social feedback for getting things done, and if you want to create a specific habit or meet a goal in a specific length of time, Lift can be a good choice for you. I think I’m going to go inactive on it, however, as I’m not really finding it motivating.
