Hi HN,

I got really annoyed by my Android phone's ambient light sensor adjusting the brightness too often and too much. But turning off the automatic brightness lead to getting blinded at night, which was not a good solution.

So I decided to do something about it over a weekend some time ago. The result is a simple app that adjusts the brightness to follow the outside daylight. When the sun goes down it starts ramping down the brightness and when it goes up again it ramps it up again. The times of sunrise and sunset are calculated from the current location.

I've found it actually works quite well, so if the standard automatic brightness annoys you as much as it annoyed me, please try it out.

It's available on Google Play market here: https://play.google.com/store/apps/details?id=se.japanska.android.daylight

There's also a free one-week trial here: https://play.google.com/store/apps/details?id=se.japanska.android.daylight_lite

I'm a long time lurker that recently quit my job to work on my own projects, a lot due to the inspiration from Hacker News.

Now I have published my first serious project, an app for learning how to write Japanese characters. It's the app I always wanted but couldn't find when I was studying. It tries to be simple to use, you just start the quiz and go with the flow. There's no need to plan and manage your studies, and it uses spaced repetition for better retention.

There's a promo page with more details up at http://www.kanjibyhand.com.

It's only for Android so far. The free version includes hiragana and katakana:

The paid version includes (a lot of) kanji:

I'd be grateful for any comments or ideas for how to market this app!
