A Wonderful App

Scootch Tastic!

Everything you'll ever need. Never had an issue ever since I had it. Since this is now a Legacy App it's awesome they created a new app for people using iOS 10 and above.

Nifty App


This is a very useful app. I like all of the information igives on encoding/decoding. The only problem: I can't find the dictionary it talks about.

Useful Tool


Wish I had something like this for a couple ARGs. Handy to have a bunch of tools in one place.
