Real-time barometric pressure, altitude, and fishing activity — all powered by your iPhone's built-in sensor. No internet required.

FOR FISHING ENTHUSIASTS

Barometric pressure directly affects fish behavior. When pressure drops rapidly, fish feed aggressively — that's your window. iBarometer helps you spot those moments with real-time trend tracking and a simple fishing activity score.
