Long-term time lapse photography on the cheap

[GetFrodo]

I want to do an Autumn/Winter/Spring time lapse video (with my Android smartphone) over a period of 6 months to result in a video of about 2 minutes. This works out about 20 photos per day.

I have apps which I can use to set a simple interval, but I presume that it would be better to film only during daylight hours (e.g. a photo every 20min between the hours of 8:30 and 3:30) to avoid flicker and boring/black sections. I haven't found any app that does this kind of scheduling.

So DAK
- am I barking up the wrong tree w.r.t. avoiding night time shooting?
- any suggestions for an Android app that will do this kind of scheduling?

Many thanks you Lemons
