Split costs fairly
Lake rental, boilies, tolls, food: everyone adds what they paid. Split equally or per person, and Carpio works out who owes whom.
Carpio keeps the costs, catches, weather and leaderboard of every fishing trip in one place. With automatic air pressure and moon phase for every fish, and a carp score for the next 14 days.
No more Excel sheets, scattered notes or hassle in the WhatsApp group afterwards.

Weight in kg and lb, species, bait, swim and photo. Air pressure, trend, temperature, wind and moon phase are added automatically.
A score from 0 to 100 for your water, with pressure chart, moon phase, feeding periods and the best time of day.
Who catches the biggest? See the top 5 and discover at which pressure, moon phase, on which bait and swim you catch most.
Invite mates with a link, WhatsApp or QR code. Friends without email or a smartphone can join as guests.
Save the GPS spot of every catch and see on the satellite view where you catch best. With your own depth map alongside. Only visible to your mates.
Give the big carp on your water a name. See when "Big Scale" was back on the mat, what it weighed and who caught it.
Log rig, hook, depth, distance or wraps and water temperature. Track missed bites and sessions without fish too: so you also know what didn't work.
No signal? No problem. Catches and costs are saved and sent as soon as you're connected again.
Made for your phone, with big buttons. Works on your computer too.
