Due to the need of reliable integration of all sub-systems like gyro, isonometer, ambiance light sensor, and other critical components; at this moment there is no other system that we feel is reliable to do the job beside the iOS 5.01 from Apple computer. When new generations of iPod Touch comes out; base on past experience there is a very high possibility that the iPod touch will also be supported if the lens system and the CPU is fast enough to do the real life hunting job, it will be also be supported (i.e. a lens system and a bracket will be made). As mention above, processing speed and subsystem is critical for iBowSight to work reliably, the current iPhone 3 and 3GS just do not work very well, thus is not supported.
To be perfectly put in the bracket with +/- 0.003" every time you mount your phone, please name a case/mount combo you think will work. Apple assume me that the only thing on the iPhone that is made extremely precise is the stainless band which is +/- 0.001". So if there is going to be a rain/vibration cover, it will have to cover the phone after the lens and the phone is mounted. A water proof case like the life proof case may be totally waterproof/shock proof, it is useless as far as a sight is concern. Remember, one need to take it off and on and maintain no less than 0.003" variance or it becomes a toy!
It is always a good idea to put iPhone in Airplane mode when using iBowSight. As when the phone ring, the dominent app will be the phone app and until one put it in backgound and put iBowSight back at the forefront; the app was sent to back and cannot be seen. It will be devesitcating when one is pulling back at a deer with aim and ready to shot when then happens. We are working and looking at possible buys out as a solution when iBowsight is the formost app in the near future release. That said, iBowSight is code from scratch using iOS5, whcih means all text messages will only roll on the very top of the screem whcih will have no effect to the operation of iBowSight when one receveing text, even when it is not in Airplane mode. below is what happen when iBowSight is the Foremost app when a text message was received.
