Poltrax Tracker vs ExitPoint Skydiving

Poltrax Tracker turns your phone into a GPS tracker for competitions and sporting events. Scan or enter the code provided by the organizer — Poltrax Tracker downloads the event configuration and starts showing your live position on the organizer's map. Signing up on site? Scan the sign-up form QR — you sign up in the app and the phone connects to the race by itself. How it works: 1. Scan the QR code (or enter the code) provided by the organizer. 2. Allow access to your location. 3. Put your phone away and go — your position is sent in the background, even with the screen locked. Why Poltrax Tracker: • Runs in the background — your phone can stay in a backpack or pocket (a persistent notification shows that tracking is on). • Automatic start — tracking switches on by itself at your start time. • The race map at hand — “See the race map” shows you and other athletes live. • Offline buffer — if you lose signal, positions are stored locally (encrypted) and sent once you are back online. • Battery saving — smart position sampling modes. At 20% battery tracking stops so you can still use your phone, and it comes back by itself once you plug in a charger. • No account needed — pair with a start code, no paperwork. Poltrax Tracker works with the Poltrax timing and visualization system used at runs, cycling events, rallies and regattas.

ExitPoint Skydiving: The skydiver's toolkit. I've been skydiving for almost 20 years, and ExitPoint Skydiving grew out of me wanting a more precise way to calculate cross country jumps. Then it grew some more... It's completely free, with no login required to use it. What's inside: Canopy Size Calculator: See what canopies you can legally jump today, and how many more jumps you need before a certain size, across multiple national rulesets (USPA, Sweden, France, Australia, and more). Wing Loading Calculator: A quick lookup to figure out your wingload. Canopy XC: Plan your exit point for cross-country canopy flights, with live wind data and glide calculations. Flying Blind: Find your way back to the landing zone fast, in poor visibility, with no planning required. Find My Main: Estimate where your cutaway main landed after a reserve ride, using current winds. Jump Run Separation: Calculate safe exit separation based on wind, ground speed, and group type. Find a Drop Zone or Wind Tunnel: A worldwide map of skydiving dropzones, wind tunnels, wingsuit tunnels, riggers, and gear stores. Event Calendar: Discover skydiving boogies, competitions, courses, and demos worldwide. I'm still building. If you have feedback or a tool idea, there's a feedback form built right into the app; I read every submission myself. You can also submit events, drop zones etc. The app becomes better with the community. Blue skies.
