Grinders Gear GTA is a third party companion app that helps you keeping track of the fully upgraded ingame businesses and time based cooldowns that help you speed up your earnings in game.

Please note that it is an early build, yet it is already so useful I decided to publish it. The following things will come in later updates:
- Trackers for all stages of business upgrades.
- Research can be traced and production will be adjusted.
- Helpful shortcuts so you don't have to adjust product manually after a sale
