Rypl is another solo project of mine, and I designed the backend entirely using the Parse BaaS SDK. Rypl is a private group video sharing/messaging app.
You create “streams” (small groups of friends) and share rypls (short video clips) with the stream. Think like Instagram video, but keeping your videos private amongst small groups of friends.
Rypl was doing great, but 1 month after it’s launch, Instagram launched “Instagram Direct”, which was basically the same thing as Rypl. Seeing as there are still users, I have left Ryple active in the App Store.
