Go into your device settings and, on the left hand side scroll all the way to the bottom. The last option should be “About Device”. Check Android version. If it’s 5.0 or higher, you’ll be able to use Predictable for Android. Now Check the device name and model number. If you do a quick search online for “<model name> <model number> device specifications” you should be able to find out information relating to the device including its RAM. If the RAM is 2GB or higher, then you’ll be able to use the app.
