For $14.99 I would expect the app to be flexible enough to do trap, skeet, 5-stand, and sporting clays. The way the app is currently designed it only works for skeet and sporting clays. It does not work for 5-stand. The current implementation assumes all shooters will be shooting the same station, one station at a time. I bought the app thinking that for $14.99 (the most expensive app Ive ever bought), they would have regular updates to make the app more capable. I bought the app 4 months ago and I have not received any updates. Their web site seems to indicate they will be developing a separate app for 5-stand. I would suggest that you not develop a separate app, but make this app capable of all the various shooting sports. I would not recommend this app to anyone shooting trap or 5-stand.
