I can keep track of canopy line sets, which is a plus these days! Also setting the altitude beeps is a breeze ! ### 1/5 — “App may change settings on error” *2025-03-01* Before using the app, there’s disclaimers you have to accept. One of them is that the app may change device settings on error, the other is LB may terminate the app in the future and the third is they may introduce costs to use the app. If you can’t trust your own app, I won’t trust it either. Lastly, the app is gated behind a login. You need to create an account before using the app. I do not understand why everything needs to require me to have an account, just let me store settings locally on device, I don’t need to sync it. ## Frequently asked questions about LB Altimeters ### What is LB Altimeters - JumpTrack used for?
