Great but... I'm missing configuration backup to SD card/cloud option, so I could easily copy config to another device & wouldn't have to manually configure it every time I make factory reset.
Since kitkat update It puts commands into sms message along with the normal sms status from alarm (were as before it didn't do it unless you manually typed command in sms)
The best so far... I've tried a few of these sms control programs and most have ranged from unworkable to poor. This works well but there are a couple of niggles. It's a very useful app and I look forward to future updates.
