A quick message to evneroye who has viewed my three little videos over the past week or so- Many thanks for the comments and feedback-I have tried to respond to evneroye, but as the insults came in I decided to just sit back and let the pictures speak for themselves.I Live in Wales UK, the first video was taken in a place called LLithfaen, and the second (taken the next day) in a place called Pwllheli. The first video was taken at roughly 3.30pm and the second at probably 2pm the next day.

POSTED October 7, 2012 at 4:42 amIf you decide to branch out into developing this or something similar for Android, I’d love to be on board as a tester. I can’t find anything in a traditional to-do list or planner system on Android that quite meets my needs and this would be very close. Despite having many great to-do list apps, Android seems to be lacking in other productivity type apps.
