There are some obvious contenders for 'Best messaging app' including WhatsApp and Facebook Messenger to name a couple - but ‘Drupe’ in my opinion, is the one messaging app to rule them all.
Unfortunately, it is only for Android users, and according to Business Insider, “the Drupe App makes your iPhone friends jealous”. If you have not heard of it, that's because it's relatively new on the scene.
Drupe displays your whole contacts list, and then lets you contact people using any of the most popular messaging services - WhatsApp, SMS, Skype, you name it. So from this one app, you can essentially contact anyone using any messaging app you want. It's awesome!
It’s available on playstore for free. You know what to do. J
