The scheduling seems to offer a lot of options, but the layout seems a tad confusing. I'm confused as to why you have two lists to specify when to turn the repeat on and when to turn it off. If you only used one list, the days that were checked would be the days that were on, and the days that weren't checked would be the days that were off. I see no need for a second list here.
Just downloaded now....
I like this a lot actually... I think the two repeat options is actually necessary to schedule what days the the selected feature (e.g wifi) turns on at the scheduled time and what days the selected feature turns off at the scheduled time.
Turn airplane mode on at 11.30pm (Repeat Sun, Mon, Tue, Wed, Thu)
Turn airplane mode off at 8:00am (Repeat Mon, Tue, Wed, Thu, Fri)
This would turn on airplane on school nights.
If you look at the Timeriffic scheduling app, it is also designed this way with Repeat on time days and repeat off time days.
Good Job OP.... I'll keep using this app i think!
