I've gotten reports that ourlaps "doesn't work" on ios anymore. I tried it on my ipod touch which had 8.4 on it and "it worked". Then I tried 9.3.1 and "it worked".
Then I put my earpiece in, lock the screen and it "doesn't work". Pull car over, unlock the screen and "it works".
So (cr)Apple has done something... which they always do...
I've created a ticket with them to see if this is a bug on their end or a new feature that can be disabled with a setting somewhere.
In the meantime, if you are using ourlaps on iOS and it works under the lock screen while in your pocket please tell me the iOS version you have.
