SAVE YOUR SPOTS

You spent hours finding that gravel bar. The silt gully off the point. The clear patch between the weed beds. Save the wraps, the horizon marker, the substrate — and get the rods out quietly next time.

No more disturbing the water. No more forgetting what worked. Your fishing spots, saved and organised.

LOG WHAT MATTERS

Fish shows at dawn. A capture on the new moon. The swim that produces on a wind change. onfish captures the details that add up — so you can see the patterns others miss.

Log your catches with photos, weight, bait, rig details and conditions. Keep session notes and journals. Track your fishing diary across multiple lakes.

SEE THE BIGGER PICTURE

Every session teaches you something. onfish organises your observations so the next move becomes clear. Weather, moon phase, conditions — all connected to your catches, sessions and observation logs.

Spot the patterns. Make better swim choices. Catch more fish.

TRACK OTHER CAPTURES

Know what's being caught and where. Log captures from around the lake to build a fuller picture of fish movement and feeding patterns.

YOUR DATA, YOUR EDGE

onfish is secure by design. Your spots, your notes, your hard-earned knowledge stays private. Built for secret squirrels, by secret squirrels.

Your fishing log stays yours. No sharing, no social feeds, no data selling.
