Use EloView to deploy your apps to auto start on the device. See our knowledge article: How do you navigate and use the content deployment features in EloView 3 (EV3)?

Are there any 3rd party apps I can install on my Elo Android device that will allow me to implement or manage auto start of an application?

Elo does not provide or recommend any 3rd party apps to manage auto start on Android applications. If auto start is a feature you require, you might consider using EloView to achieve the desired results.
