Description
Mojo TSD Navigator is a precision timing tool for time-speed-distance (TSD) rally navigators (co-drivers). It continuously calculates whether your car is running early or late relative to the assigned average speed, allowing the navigator to give accurate, real-time guidance to the driver and achieve zero-error timing at checkpoints.
How it works:
Uses the device’s internal GPS to measure distance traveled with 0.001-mile resolution
The navigator enters the assigned average speed(s)
The app calculates how long the distance should have taken at that speed and compares it to the device’s clock
Once per second, the app displays exactly how early (ahead of schedule) or late (behind schedule) the car is
The navigator relays this information to the driver as frequently as desired
Odometer control and corrections
Includes an adjustable odometer to match the rallymaster’s official mileage
Allows on-the-fly odometer corrections whenever precise mileages are provided in the route instructions
Designed to support real-world TSD rally practices, including frequent mileage adjustments during competition
Designed for rally use
Mojo TSD Navigator is built specifically for navigators, not casual driving. The display emphasizes clear, readable timing information and minimizes distractions during competition.
Tablet recommended: While the app runs on phones, many users prefer using an Android tablet mounted in the car. A tablet provides a larger, easier-to-read display and is more enjoyable to use. We can recommend the Samsung Galaxy Tab A tablet. Be sure you use a tablet that includes GPS.
Easy to learn
The app includes a detailed operating instructions document that explains every feature and walks the navigator through real TSD rally usage step by step. No prior rally app experience is required to successfully use Mojo TSD Navigator. Bottom line - this app is designed to eliminate the guesswork of asking "are we on time?". It not only improves your checkpoint scores, it makes rallying more fun for both the driver and the navigator.

Great app. Little adjustment time from physical rally computers like Alpha Pro. I do wish the app handled time delays better/more like Alpha Pro which was straight forward and intuitive. Where the Mojo is a little more interpretive for lack of a better word. Some features took a bit to figure out. I imagine this will get easier with more experience. The app overall accuracy, reliability & performance during the rally was solid, and it provided all the key information I needed.

Solid TSD rally app for rallies that don't allow uploading the route book to a rally computer. Developer is great at supporting too!
