To allow Sleepmeter with your sleep history database to be installed on an SD card, the widget is provided as a separate minimal app that is free of charge. Use the "Where's the damn widget?" button under the help menu in the app or search for "Sleepmeter Widget" in the market to get it.

You are welcome to write whatever you want in the Android Market comments, but I've given up on reading them. If you want to get my attention, send an e-mail. I usually answer them promptly.

Explanation of required permissions:

POST_NOTIFICATIONS: This permission is needed for the debt notification.

I've been using the this since 2012 and I have 8 complete years of sleep data in it now. Its a great app but the widget hasn't worked properly for the last couple of android versions. It still allows you to stop and start sleeping which is good but it never updates with awake times any more. It doesn't stop the app being good but the app hasn't been updated for years either. I am paranoid it'll stop working some day and I will have to move on. Are you still there developer? Heeeeelp!

Now that the dev has returned, decided to buy the full version to support. 100% worth it even if it was (functionally) frozen in time! Thank you!
