This is brilliant. Thanks!

Are there any other similar apps out there?

For Android, I like Habit Streak Pro [1]. You give a list of things you want to maintain a daily streak on, and then it asks you at the same time every day how you did.

My longest recent streak was a 5+ month one on sticking to a restricted diet. The power of that was amazing; any time I considered straying I'd feel like I would be throwing away months of work. (I finally broke the chain on day 3 of the flu; I was miserable and wanted comfort food.)

My tips: Have it ask you the daily questions first thing in the morning, so you start your day with a reminder of your streak. And try to keep the number of goals very low, 1-3. More than that and I find it too hard to build good habits.

Depends what you're looking for exactly - I use http://www.joesgoals.com/ to track multiple goals, which is a more complex variant on http://dontbreakthechain.com/.

Daily Badge would do the trick. https://play.google.com/store/apps/details?id=com.mhillsyste...

I like the simplicity of chains.cc. The only downside is that there isn't an Android app.

You can use RescueTime to automatically track how you're doing against goals you can configure like "spend at least 1 hour in Sublime Text"

I use an app called goalstreaks.

Far more minimalist. Just a calendar and mark, but I can set reminders and view my overall progress.

If you need more motivation than the other apps, you can try beeminder.com which will fine you (!) if you don't achieve your goals.

My favorite is 42 Goals.
