Being a kindhearted generous person, I have been volunteering at the local
senior citizens center where I'm their ad hoc tech-support guy for phones.

Most have problems deciphering all the buttons that need to be pressed,
particularly when obnoxious ads pop up in "free" Android/iOS apps.

Most also have issues typing as they have the zoom set to microscope level,
such that even I can't find half the buttons as they're often off screen.

With that limitation in mind, I "thought" I had found the holy grail of
free voice-activated/speech-output AI when I found out about 1.800.CHAT.GPT
(but we found out within 20 minutes that it's limited to 20 minutes/month).

Given the goal for these senior citizens is...
1. free dedicated app
2. unlimited use
3. no ads
4. hands free
5. no login requirement

I can only obtain, so far, 3-1/2 of those 5 requirements, unfortunately.

The best I can find that is (almost) hands-free is gemini/bard by Google.

Specifically, this is the free no-ads unlimited Gemini GPT APK for Android:

And this is the free no-ads unlimited-use Gemini GPT IPA for iOS:
<https://apps.apple.com/us/app/google-gemini/id6477489729>

Unfortunately it requires a login, and no, we don't want to use a browser.

Given Gemini appears to be the best - but it's not yet 100% hands free...
Do you know of anything better than Gemini for unlimited 100% hands-free?
