Snap Map vs Zenly, two takes on the friend map
Quick answer
Snap Map is a tracking layer inside Snapchat; Zenly was a dedicated friend map that closed in 2023; Parages keeps the friend connection but shows no live map and pings only when you're nearby.
Snap Map sits inside Snapchat, dropping your Bitmoji on a shared map for the friends you allow. Zenly was the standalone original, more precise and more social, before Snap acquired it and closed it in 2023. Snap built tracking into a chat app; Zenly made the map the whole point. Both put your live dot in front of friends by default. Ghost Mode exists, but the map is still the premise. Some people wanted the connection without the dot.
In one sentence
Parages pings you when you pass near a friend. It tracks nobody.
