Hello www,
today I want to show you in my opinion the best and easiest to use wallet apps for Android.
My recommended wallet apps are published by freewallet.org
They are easy to use and secure.
They have a lot of wallets for nearly all "every-day-paying" cryptocurrencies.

You can make all your wallets secure by setting up a pin password.
These wallet apps have a simple and easy to use overlay...even idiots might be able to use them :P

The best feature is the chart where you can see the actual price and the price behaviour during the last day, week and month.
Again, this is my personal opinion. I just wanted to share these apps with you!
