Rocket Trail for iPhone is a fantastic tool for any rocketeer! Now, you can simulate a launch of any Estes rocket in the palm of your hand, hit the launch site with this must-have tools.
Rocket Trail allows you to select a rocket, parachute and engine, and it will calculate the projected altitude of your launch. Rocket Trail calculates the effects from weathercocking and drift to predict your rockets landing zone using current realtime weather data. How cool is that!
Dig into the data and examine the physics involved with your launch. View your rockets
. Engine Thrust Curve
. Forces acting on your Rocket
. Drift effects from Wind
Rocket Trail can also be used to measure you rockets actual launch altitude. Set the location of your launch site and your distance is calculated using your GPS location. Augmented reality is used to help locate your rockets predicted launch altitude and display measurements.
* Fixed application hang/crashes
* Fixed zero mass rockets causing invalid flight data
Ratings and Reviews
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.
Ok, it crashes so therefore it adds aggravation.
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
Incomplete and crashes
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.
With Family Sharing set up, up to six family members can use this app.
