I have four kids, & prefer to manage the timers on my phone. Problems are: 1. When one alarm goes off, it doesnt tell me which one, so after I turn off the alarm, I have to go into each profile to find which childs time expired. 2. When asked for the password, the password is displayed, instead of ****. 3. It would be really nice if I could recycle a timer instead of having to delete it, enter the passcode, & create a new timer. Or at least give the option of automatically deleting the used alarms, since the password already has to be entered to turn off the alarm. Or maybe the option of deleting multiple alarms at once instead of having to enter the password with each alarm deletion. 4. Finally, today I got the message, "Time already exists for selected date or you tried to add timer in the past." I often have a couple timers running simultaneously, so I dont know why this came up today? But since it wont let me add an alarm, the app is fairly useless to me. Perhaps it is very useful to parents if it is installed on the childrens devices, but for children on the autism spectrum, to have their play suddenly cut off without any warning, is very upsetting. I prefer to hold the time reigns and give them a 1 or 2 minute warning to wrap up.
