Voice Over support for blind iPhone users?

I am a totally blind longtime iPhone user. I just learned about BLYNK today from a spark fun email promoting a BLYNK and IOT development kit. Based on the information on the spark fun site and also the BLYNK site, this product could be a godsend. My wife and I operate a small commercial greenhouse which has dedicated automation controls in the greenhouse but no means of monitoring remotely, let alone changing the status of critical equipment remotely. However, before I start laying out money for hardware and spending time coding sensors in control logic, I would like to verify that your iOS app is voiceover compatible.

I have downloaded the app and on first glance it appears workable (though a little rough) from a VO standpoint. However, without having it linked to some hardware, I cannot fully test. Please advise.
