What's New in SmartLaunch 2

2.31

April 11, 2017

This app has been updated by Apple to display the Apple Watch app icon. Fixed a little interface glitch. Working on a major interface update for all size devices soon. Added the latest updates I have for commercial motors. If you do not find the motor you are looking for please drop me a line and I will see what I can do.

Simple, easy to use, accurate

The title says it all. The simulations match what other simulation software and apps compute, so it’s as accurate as one could expect. Thanks for developing a great tool for the masses!

The version on the App Store says 2.31, but the app says it’s 2.30. Can someone tell if I’ve got the latest version and it’s just a bug?

Great app just one gripe with it

I love this app and is fairly accurate to what I’ve experienced with my launches. However I don’t have an altimeter to measure actual heights so the Cd value is likely off a bit. My only gripe with the app is the lack of certain rocket motors, namely the f15’s from estes that I use regularly. I’ve put in a f26 as a placeholder but would like to see a preprogrammed f15 or an option to put in your own engine parameters

Smart app

Very impressed with the physics programmed into this tool. Gave it a 4 out of 5 because an F-15 Estes engine was not listed.

Great app

Great app to validate parameters for launch.

Won't work!

Can't change motor or get preloaded kits to select and save
