Jump Master Calculator App Reviews

I just played around with this app after spending 15 dollars on it. I personally feel that this app should be reported as dangerous. Yes we are supposed to hand jam everything however people are people and I can tell you that this app...is going to get someone hurt. HAHO solution was really bad, not sure where the imported winds came from because I had Mark Schulze up on my other computer and the winds werent even close. No difference in symbology between the HARP and the DIP. Did leg was reported but not depicted. Just really bad...

Needs the ability to go back and make changes. After the information is input the only way to make changes is to start over. I like that it has all the resources included in one app. The calculator just needs some adjusting to make it useful. Needs ability to add and save drop zones to use in calcs.

Have used the HAHO and HALO calcs, both work great. The input from winds aloft have been accurate time and time again. (Only in continental US). Next version should be able to save DIP coordinates and label as drop zones. Thats my biggest issue with this app. The map output is great and much better than the old imagery on most dz surveys. Worth the money.

I havent jumped the calcs yet. We planned a 20k haho with a bundle ( weather call

The app has a nice layout. I would give it 5 stars if the calculations were correct. First of all, the calculations for HAHO are incorrect. Not by a little either. The average velocity of the winds is not taken into account in the formula. For some reason, the V for velocity always says 0. That makes a huge difference in the distance a standoff will be. For the price of the App, I would expect a fix and an update. As of now, I have not received a response when I suggested a fix to the app developers. Needs to be updated and this glitch needs to be fixed. Dont waste your money.

I noticed the calcs are off, specifically the grid zone identifier is wrong and the maps dont show up. I emailed support several times and finally got a response back after no kidding 7 months. Still didnt give me any support or really answer the question I asked about the calcs or the maps.

Average winds are excluded and read "0" when calculating for HAHO. APP needs to be updated!
