Firefly (also known as SayHi) is a relic of the early mobile dating era that combines GPS tracking with unmoderated stranger chat. For a parent, this is the 'Final Boss' of bad apps. It isn't just 'not for kids'—it’s actively designed around the exact behaviors we try to protect kids from: sharing location with strangers and seeking out adult relationships.
In 2026, this app is also likely a ghost town populated by bots and scammers. There is no version of this that ends well for a minor. If you see this on a phone, it’s not for 'making new friends' in the way a kid means it; it’s a direct line to the sketchiest corners of the internet.
