The Solo-Safe app allows you to create a network of Supporters who will be notified if your device is inactive for a period of time you specify. The user, or “Soloster,” defines a maximum time their mobile device can remain inactive. If there is no activity on the device for the set timeframe, the Soloster’s network of Supporters is notified via SMS and/or In-App notification. The Soloster can Snooze the app if they know they’ll be offline for longer than normal. The app is free to Supporters
