I'm using a Samsung Galaxy S7 Edge loaded Android 7. I added the app, connected the phone to the CooTwo with Bluetooth and was checking tanks within five minutes.
Well.. so much for that theory. I'm also using an S7, not edge though. Also on Android 7.

Maybe there are multiple revisions of the product that account for the marked differences in experience. I have frequent app crashes with the app, it sometimes will repeatedly complain cootwo needs to be calibrated even immediately after being calibrated, and most often the cootwo and phone just won't talk to each other.

Next time it happens, try restarting the phone or closing apps. That will clear up problems with slow or no response with apps on my Iphone, though I haven't experienced it with the cootwo. I often get lag times on searches or radar loading and when I do it is cleared up by closing the 20 or so apps in the background.
 
Yep, I've done all that stuff. Last time I tried to use the cootwo I spent hours trying to get it going. I went so far as to wipe my phone, set everything back up and download the DiveNav app fresh. Eventually I gave up.

The sad part is I used to have standalone CO and O2 analyzers that I sold when I got the cootwo. Kicking myself for doing that now.
 
bummer

Sorry you're having so much trouble. . yes I'm using an iOS phone and that app seems pretty stable.

Except for the yearly(or so) CO calibration, the COOTWO works just fine in a stand-alone mode. The directions are way too hard to find on the DiveNav site, but they are there. Have you tried using it this way?
 
Is there a specific Divenav support forum on SB? I couldn't find one, but did not check thoroughly...
 
I have not had any problems. I love my CooTwo. Lots of instructional videos on their website. Just purchased calibration gas for the CO sensor and will take care of that this week.
 
How much did you have to pay for the cali gas?
