Like everyone else is mentioning, Organic Maps is probably an excellent option.

Personally, I also rather like Magic Earth, although it’s sadly not FOSS. But it does have crowd sourced traffic info, and imo a better search ux.

Can share some of my favourites

• KISS laucher
• Floris Board (keyboard, which I love to use)
• Bitwarden + Aegis (password manager + OTP)
• Eternity (for browsing lemmy)
• Mull (hardened firefox fork)
• Organic maps (maps + directions)
• Track & Graph (for tracking trends/habits)
• WebApps (running sandboxed websites)

Just begun exploring using:

• Immich (selfhosted photos solution)
• ReThink (local dns/firewall tracking blocker)

Btw, I believe Obsidian isn’t FOSS.
