I’ve just published a companion site for my free app Are You OK?.
The app is aimed at people wishing to regularly check the status of family or friends who may for example live alone and are vulnerable to accidents like a fall in their home, unable to call for help. Something like the reverse of a panic button system; if they don’t press a button every few hours, it sends an SMS message to selected contacts with a call to check in.
Head over to the website to read more about the app and find the download link.
