Basically AH is saying their “App” requires MFi aka Apple iPhone (not Android) to work. Their “App” is developed for MFi.
iPhone has an accessibility section which includes MFi, which is very, very easy to access unobtrusively once you set it up.
Yes, you can adjust programs, volume, mute, etc easily and you get a visual so you know where you are in the sequences.
No one else knows anything you are doing in this glued to your phone world. 
I suggest you get a clarification from AH exactly how Lucid works with MFi. I know nothing about Lucid. But, I do know Bluetooth and MFi is wonderful for exactly your circumstances.
Ask the question " Am I able to use the built in iPhone MFi accessibility features once Bluetooth is paired with the aids? Or does Lucid only work thru the Lucid App?"
If you only wear 1 hearing aid, AH is requiring you to buy the second MFi aid and exchange the non Mfi aid for a replacement MFi aid you don’t need. Is that right?
I can’t even find the App on iOS / iPhone but I can find it on Android / Google Play.
At the bottom, it explains what hearing aids work with the App,
Might just want to be aware that the reviews on the App are really bad.
I just checked and couldn’t find anything for AH or Lucid Hearing.
Hear is what I found in Apple App Store
App rated 3.1/5. Number of 1 stars almost as high as 5 stars. Requires iOs 12.4/later.
“The Lucid Hearing app is compatible with all U-series Powered by Lucid hearing aids models as well as Engage, Present and Fio hearing aids.”

It might be better with Apple App Store? On Google Play, the App rating were really bad.
not sure why but I am not finding, on the App Store in my iPhone 13
I searched for Hearing Lab Tech… and it shows up below before I finish typing. Select the whole company name and the app is there. There was a “Sponsored app” unrelated, of course, before the Lucid thingy.

I wouldn’t even consider buying hearing aids without Bluetooth connectivity. But there you go as others have said everyone’s different. I use my phone all day long. Many things I do on the phone include audio. Having the audio automatically streamed to both ears is wonderful and I have features in my hearing aid app that I find very useful. For example: in a noisy environment, I can turn down the hearing aids or mute them and leave streaming on and I can watch a movie or listen to a song in spite of all the noise around me. In combination with closed domes I can increase the amount of bass that I hear in music and so on. That’s great on planes. I can also use my phone as a microphone and if my wife and I have to sit apart she can have my phone and talk into it and only I can hear her. But you have to be comfortable with the technology otherwise it’s uncomfortable and a hassle I imagine. My daughter and I live in different states and we send each other videos during the day. I love to be able to hear her and I don’t necessarily want everyone else hearing her. So that’s a plus also.
I think that to some extent the bluetooth capability may be a be over rated but I my wife and I both use the Phonak TV Connector with my Paradise 90Rs and it has transformed my tv watching. It’s worth having it for that alone.
I really enjoy my phone streaming to my aids. I use that alot.
I do from time to time in noisy environments bring up the Resound app to tweak the equalization/ noise parameters. I wouldn’t call it indispensible. I’ve added a program that I can call up with the hearing aid button called UltraBofus (tweaks on the Resound UltraFocus program) that works pretty well.
LOL Heh heh. That’s funny.

With my loss, if I streamed into my aids during a plane flight I would be blasting everyone around me with my stream. My gains are high enough that even with custom molds, others can totally hear what im streaming
It sounds like with your loss you may have forgotten how loud the interior of a plane is. On the other hand you could wear the kind of headphones they wear on the tarmac OVER your hearing aids to keep the sound in. 
I understand that my wife claims she can hear my aids when ever it is quiet in the room and I am listening to a audiobook.
Not sure about any apps but I use my smartphone to stream stored music to my HAs (KS9s) when I run/walk as well as sound from my computer – YouTube videos, zoom sessions, video sessions with my dr, etc when I don’t want to disturb anyone in my family. I’ll be honest, I never change the volume of my HAs via the aids themselves, but will do so using the app.
My biggest complaint with the bluetooth function on my HAs is that oftentimes after I receive a call my HAs mess up. One or the other or both. They go into a hyper loud mode and I have to open the battery door and close it again to reset the aid. Sometimes it is a volume adjustment that CAN be reset on the app but most of the time I have to do as described above. This is tiresome and leads me to either turn off the bluetooth connection to my phone or leave the HAs on the bathroom counter in the dryer. I have gone without my aids for 4 weeks now other than putting them in for church on Sunday mornings and most of the reason for that is my frustration with the BT connection and the aids needing to be constantly reset after a call. I love the streaming to the aids via BT but when a call comes in 100% of the time I have to reset at least one of the aids after the call ends.
I have been wearing aids for a little over 18 years, and with some form of connectivity for about 12 years. I have come to accept the glitches and once in a great while need to have my aids repaired as a part of the process of having to wear hearing aids. I have always worn my aids from the time I get up until I go to bed. I have always had yearly hearing test and checkups. My aids are cleaned and either in a dryer or charger each night. Now with rechargeable aids the charger does the drying.
I was raised by parents that believed in discipline and a regiment that became a daily schedule. I have always adapted my daily routine as my life has changed. Even now in retirement I have a strict schedule.
These are the Sam’s Club aids? What do the folks there say about these problems. I don’t recall any other reports about these aids if that is what they are.
Hope you get it sorted!

Chuck, my wife says she can hear mine as well, and I know she can hear my phone calls. I don’t stream those.
Absolutely worth it! Has enormously enhanced my life. Taking hands-free calls and streaming radio and other audio have taken hearing via aids to a whole new level for me.
