Well the device is setup to accommodate an external trigger from the get-go - and they're not expensive ($35) - so it was anticipated. They just decided not to sell that cheap component. The unit works very well as advertised. No complicated workarounds. (I've not had a single issue using the recoil trigger.) As far as the unit itself is concerned likely the most important rev 2 feature would be improving the alignment. The "notch" could be better designed. But again, there's always ingenious people out there who, with a few spare parts and some hot glue, can design a cheap improvement.
Frankly I see no purpose for the app currently and don't even bother with it. (If you want to critique the app you could add also the fact that you can't update the unit's firmware from it, sending the file via Bluetooth rather than having to use an SD card.)
So while you wait for the ver 2 everyone else is making good, easy and reliable use of their units. Just don't bother with the app for now. And understand the severe limitations of only looking at sample set statistics, no matter what calculates them for you. In my opinion, the app is completely useless if it doesn't calculate the relevant statistics - and sample set mean and SD ain't them.
