### 1/5 — Imperial units no longer works.

*2017-12-06, version 1.7.3*

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.

### 2/5 — Program constantly crashes

*2016-12-22, version 1.7.1*

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

### 5/5 — Great app

*2015-08-30, version 1.7.1*

Best rocket app for iPhone and iPad. Works great.

### 1/5 — Nach Update nicht mehr zu gebrauchen

*2013-11-27, version 1.7*

Habe mir die App vor 4 Jahren, als sie gerade frisch raus war, gekauft, und nun ein Update durchgeführt. Leider fehlt die Option, Raketen selbst zu konstruieren, völlig. Dafür kann man jetzt, aus welchem Grund auch immer, Kisten für eine vorgefertigte Auswahl an Raketen konstruieren.
Diese Version ist für mich völlig sinnlos, schade um die 8,99€.

### 2/5 — Less than expected

*2012-11-23, version 1.6*

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.

### 2/5 — Eh

*2012-08-07, version 1.6*

Not worth the $10.00!!

### 5/5 — Works great with latest versions

*2012-04-14, version 1.6*

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.

### 1/5 — App doesn't work anymore. And numerous emails go unanswered.

*2011-10-11, version 1.6*

Used to work OK now app developer just shines it on. I will report back when this works again, if ever.

### 4/5 — Love it but!! V1.6

*2011-09-05, version 1.6*

Great app but wish it had a way to set measurements throughout to either metric or standard. Some of us yanks appreciate standard so we don't have to convert and take up precious time.

### 3/5 — What???

*2011-08-26, version 1.5*

I like it it just doesn't have flight simulation and I'm bummed about that :(
