### 3/5 — Very useful app

*2016-07-29, version 1.1*

Nice app. Produces very useful data, however it just misses being one of those gotta-haves on the field. The one thing it really needs is time to apogee. Either from launch to peak, or from burnout to peak - necessary info when selecting an ejection delay. Thrust/weight ratio data would be helpful too. It would also be great if one could enter data in inches and ounces; not arguing the merits of one system over the other. We use both in America so the ability to use both would make all the difference.

### 5/5 — Super useful!

*2016-04-03, version 1.1*

I love this app for doing calculations out in the field. Really thankful for whoever made it.
