User reviews

Beautiful but unusable

The nag screen pops up instantly after selecting a track. Zero value in the try-before-you-buy version.

Response from developer

Hi, Thanks for the honest feedback and for the kind words on the design. You're right: the upgrade screen shows up too quickly once you've opened a few flights. I'm adjusting that paywall timing for the upcoming update so you can inspect your flight logs more smoothly. In the meantime, the built-in demo flight has every feature completely unlocked with no upgrade screen, so you can test all the tabs before deciding. If anything else gets in your way, please reach out through Contact Us in Settings and I'll help directly. Best regards, Rush.Tools

Not working black screen at start up

Seems very nice but it is not working. When launched, black screen and nothing happened. No UI nothing.

Response from developer

Thanks for taking the time to write this. You were right: the app was stuck on a black screen at launch. Version 1.0.2 is now live in the App Store! This update completely resolves the startup issue, and the app now opens instantly every time. Since you liked the look of it, please update to version 1.0.2 and give it one more try. I would love to hear if it works smoothly for you now! Best regards.
