Rocket Trail

This app works good for MOST Estes rockets, however the list is not complete. The observe function works good for calculating the altitude and distance of the rocket. I have not had any problems with the app crashing. Other than not including a few rockets I was able to find some similar rockets, at least in height as this is what truly matters. The list of engines is not complete either, but on most Estes rockets you are given multiple engines, which have roughly the same result. This app is not 100% accurate, but does work for estimating the landing area.

What it says the app is I like the idea, but it crashes. Started out seemingly fine, first time I picked the rocket then as soon as I picked the engine it immediately crashed and kept crashing after that as soon as it opened. Restarted iPhone 6 thinking that might help but does the same thing, then I deleted and reinstalled it and it seemed to work better and got to play around with it and still crashed but I could open it back up this time. Like I said, I like what the app promises and soon as it's fixed and it doesn't crash I'll definitely change the star rating. I put two stars but I'm sure most would put one star being as how it doesn't do anything except crashing to the home screen often. My iPhone 6 has the latest updates, Thanks

This app isn't even worth 99 cents. I bought and installed it today, and will uninstall it momentarily. You can select a rocket-engine-chute combination (including ones that make no sense), IF you can manage to find your rocket and engine in the long lists (there is a fairly useless search capability). Then you can identify your launch location and see a "bullseye" around that location. There's no indication or explanation for what the different concentric circles represent in the Launch Site "bullseye." There are a bunch of fairly useless charts provided as well. You cannot add rockets or engines, or see any detailed stats that would help you to know what they are using in their calculations. I want my 99 cents back.

The lists of rockets and engines could be more complete and cleaned up some for a better user experience. The results are fairly accurate, but there are opportunities for improvement, especially in usability. Good additions would be: * Save configurations with photos and user info (kit info, build date, notes) * Log launches including, photos/video, maps with plotted locations and other relevant data. * Export It's a good start, but incomplete. For a paid app there should be more to it.

The description led me to believe the list would include all Estes rockets. Instead it's a very short incomplete list leaving out Estes kits such as the 2157 Saturn V, Maxi Brute V2, Big Daddy, and too many more to name here. The app also crashed the 3rd time using it and required deleting and downloading it again so it would work. Update: still crashes and seems just random now when it does leaving it unusable until I delete and download again. I'm having these problems on the iPhone 6 Plus which is up to date and not jail broken.
