I love Organic Maps. Works on Android and IOS. Fully offline (maps predownload at first run) and all route calculation is locally computed so it's especially good for hiking or where signal is poor.

Only thing I miss is live traffic updates but for me that's an acceptable tradeoff for the ultimate offline privacy as far as a digital map can do it.

The voice it uses is whatever's built into the phone's accessibility features so on some devices it sounds a bit janky, but on Android at least you can install different ones if that bothers you.

If it meets your requirements, try Vela Maps which is a degoogled Google Maps.

" A degoogled maps & navigation client for Android - what NewPipe is to YouTube, for Google Maps. Open vector tiles for the basemap, the device itself scraping Google's public web endpoints (per-user, no backend) for the things only Google does well: POI quality, routing, and traffic-aware ETAs. Built to run on GrapheneOS and other no-GMS ROMs. "

I think it's a fairly new product and seems to be rapidly improving performance with quite a few updates lately. (I have discovered some glitches but they seem to be addressed as soon as the app updates the next time.)

It might meet your requirements because it's not Google Maps.

It might not meet your requirements if you want a truly no-Google product, because it uses a few Google things anonymously in the back end...

I was using organic until CoMaps forked it, now CoMaps is the way. It's open street map so you can sign up and fix whatever you want, pull down the next version and it's there.

I do miss street view, ~~voiced street names~~, and really miss cowdsourced hazards from waze but it's worth it if you're not on a long high speed trip.

edit: turns out you can turn on tts street names

I'm using OSMAnd+ myself. CoMaps is another one that uses OSM as the backend but is much more minimal in design.

For both, I use GeoShare which can interpet a google directions link when searching an address on my phone and pass it to OSMAnd+ or CoMaps (or, like, any other map app)

I've just started using MapQuest like many others since the lake ontario thing. It's been pretty good and I find it a lot more functional and accurate than the Foss options at the moment. It's not perfect but it's also not Google or apple.

If OSM isn't good enough, make it better.

I use HERE WeGo. I switched over a month ago and haven't had a problem yet.

I have a standalone GPS like it's 2008, in addition to excellent offline navigation it also probably doesn't spy on me

Comaps works well for me. If it's not comprehensive enough, contribute! OSM is crowd-sourced.

I use CoMaps when navigating: https://www.comaps.app/

I also recommend Obtainium for installing it: https://obtainium.imranr.dev/

CoMaps is good if you already know where to go.
I use it in conjunction with GMapsWV: look for a place, copy the coordinates with the share button and paste them into CoMaps.
Never missed an address and I use it quite a bit.

CoMaps, which uses OpenStreetMap. StreetComplete gamifies adding data to OpenStreetMap.
Sometimes Magic Earth.

The only time i use google is when i want street view.

No but I use comaps anyways

for basic things openstreetmaps based ones (comaps organic maps), for anything else no.

good or better then google maps, no, they're are a trillion $ company with major resoirces

I use OSMAnd+ its a little bit shit but ot gets me by. I also edit a little bit of Open Street maps in my area to help
