Tobu is the ultimate skydiving logbook and tracker app. Tobu was reviewed by the USPA and deemed in compliance with their logging requirements.

At Tobu, we understand that skydiving is an expensive and time-limited sport, and we want to help skydivers make the most of every jump. That's why we've designed Tobu to be a fast, efficient, and informative tool that brings awareness and accountability to skydivers, helping them progress safely through the sport.

Tobu's features include:
* Tracking jumps following USPA's SIM 3-1 C logging guidance
* Automatic calculation of key skydiving data like exit altitude, deployment altitude, deployment distance, freefall duration, canopy duration, and skydive duration
* Recording of flight trajectories for both freefall and under canopy
* Ability to add gear, DZs, comments, and digital signatures to entries
* Career summary and ability to add information about pre-Tobu skydiving career
* Export of skydive data to CSV

One of the things that makes Tobu unique is its focus on usability and efficiency. We know that maintaining logbooks can be annoying, and that physical logbooks often lack the information needed to track progress or identify areas for improvement. Tobu solves these problems by providing a digital logbook that is easy to use and packed with valuable data.

But Tobu isn't just a digital logbook - it's a powerful tool for tracking and analyzing your skydiving career. Tobu provides a career summary that gives you a snapshot of your progress over time, and allows you to add information about your pre-Tobu skydiving career. Plus, Tobu makes it easy to export your skydive data to CSV, so you can share your results with others or use them to track your progress in other ways.

Whether you're a seasoned skydiver looking for a better way to track your jumps, or a beginner looking for a way to get started in the sport, Tobu has something to offer. We hope you'll join us in making the most of every skydive with Tobu.

Sky God Ninja Turtle (Wannabe) ,


Finally! An app that tells you everything you ever wanted to know about your skydives! I am beyond stoked with Tobu! It breaks down your jump into three parts: jump run, free fall, and canopy flight, and gives you all of the metrics you would get with much more expensive units like fly sight etc. the best thing about Tobu is that you don’t need to modify your helmet or anything like that… you just take your phone along for the ride and BOOM! METRICS!!
