U must be online for this app to work

There’s no offline option. I initially thought that I’d be free to use the app without internet only for activating the app and setting up new account. I can use forward focus or receive notifications when my n7 battery was near empty. There is no such thing as offline with this app. If Cochlear website login is down/out of service then so is your listening experience. For the reason I have an iPhone is the n7. Should the app work offline for user controls? Yes. While the app is offline.. you’re basically limited to just 1 program unable to do anything else. App should only be online if it means saving settings to cloud automatically so I’m not super impressed with that. I go home and bring along the actual hardware remote control which I don’t normally carry but the downtime is really making me frustrated with no estimates to any resolution in sight (cochlear nucleus smart app has been down all week so far). You’ll just have to wait for it whenever they’re ready to make working again. Then when you lose the actual remote you’ll have bigger problem I guess. I want to give it a 5 stars when everything is working. But dock 1 star for lack of offline features I find with the app. But in this event in particular will cost 2 stars due to overall seriousness I didn’t expect when living with cochlear implant.

When it works…

I’ve had this app for a few years now since I first got my N7 processor.
My issue is I have an iPhone 8 and an iPad mini 5 and need to switch between them frequently as needed. I know I have to turn everything off on the one I’m leaving before going to the other. The problem is some times it connects quickly but most times it will say processor not found and to turn it on and move closer. Sometimes it takes 30 minutes to finally get it to connect! This is very frustrating when I need to do this quickly!
When it works it works but when it’s being horsey it is garbage!
The only reason for giving it 3 stars is the fact that if I’m not needing to switch back and forth and stay on one devise all day the app usually works pretty well unless I happen to move away from the devise and get out of range then sometimes it takes some jacking with it to reconnect! Very frustrating. I’ve ensured it has been updated but not fixed yet. Sad for such a simple program to be this buggy!

The app needs work

I gave it four stars and that is being nice. Truth is the app is not all that, I am bilateral and rarely does the app see my right processor. With that thought it also has issues with my streamers too. My iPhone 13 is up to date same with my 12 both are plus max makes no difference. My Wi-Fi is very robust and I’ve done everything I know to work around vpn off and such. The only work around is to turn off the phone and back on. Then it seems to work and even then I at times have to delete and redownload the app and it will work again. Next it just freezes for no reason and back to the work arounds I go. This IS a up to date Apple phone I’m using here so the only thing that is wrong is poor app performance. Does it work? Yes but it also drops my right processor too and before you ask it’s not my right processor. It’s been replaced and the same thing happens. I even had my right implant replaced same thing. At this point it boils down to software so please develop a better app. Before losing my hearing in a accident I was a software engineer. If you want help I would love to offer input.
