iPowerrocket

I have had this app installed since its introduction, the latest version has a much better motor library, works great on my iPhone 3GS it is nice to have at launches.

There are couple issues that need fixing to be fully useable. The motor database needs to be updated. Flight logs can't be deleted. The developer promised to fix bugs soon, but that was months ago. The issues are unacceptable given the asking price. I bought this to help support the project, but because of lack of support regret that I wasted the money.

This app is okay but if you fly large rockets and/or EX then it's not overly helpful. Rocket Calculator is cheaper and works much better.

Not worth the $10.00!!

The rocket and motor selection works OK. Whenever you choose a subheading under recovery the program crashes.

Best rocket app for iPhone and iPad. Works great.

Along with imperial units no longer working, if you select anything off in the settings, it doesn’t come back on. Should have left the old version installed. This is on an IPhone 6S, IOS 11.2.

I bought this to replace software that ran on an old Palm Pilot and to also avoid having to bring my laptop to the field. I work with high school students flying rockets and it's nice to be able to run a sim at the field to make sure the motor choice is correct, etc. The biggest issue I've had so far is entering a rocket design seems too complicated. It would be great to have a single screen to enter all the basic dimensions, and then have the opportunity to edit it further if needed. The sims matched other software I use that runs on laptops and the motor database is current, which is a big plus. If I had the ability to quickly enter a rocket diameter and weight for a fast sim I'd give it five stars. The students I worked with thought it was great to see something that used real 'rocket science' on an iPhone.
