Torn Tools
Here is a list of recommended websites, extensions, scripts, and apps to help play the game. Some of these will work with TornPDA (the app for your phone) and all will work with a browser.
Torn PDA
A mobile app for iOS and Android that gives you a full-featured Torn experience on mobile with notifications, energy alerts, and more.
Websites
Look at the How to Level guide on how to use this.
Tons of great info. Use this to create your target list to help chain and find merits you're close to reaching.
Use this to find chain targets that offer the most respect once you've out leveled your early chain targets.
Browser Extension
If you're only going to install one thing, make it this. By far the most comprehensive tool available.
Here is the list of all the features: github.com/Mephiles/torntools_extension/wiki/Features
To unlock most of the features, you need to add an API key in the TornTools settings. If you need help with that, just let us know.
Scripts
These will require Tampermonkey to run in a browser.
Only needed for the Easter event. This makes it really easy to find eggs.
