Fishing spots
Save your own fishing spots and browse places shared by the community. Depth contours help you study the shape of the lake bottom where depth data is available.
Your spots are private by default. The map supports trip planning and is not intended for navigation.

Our story
The idea for Uistio came from my own experience. Fishing information, tips and spots were scattered across the internet, and I struggled to find information in international apps that was relevant to my fishing in Finland.
I wanted to build a place where anglers in Finland could talk, share their experiences and learn from one another. The idea is a platform that brings the different sides of fishing together and grows with anglers’ needs.

I’m an angler from Turku, Finland, and I’m building Uistio on my own. I study Business Administration at Turku University of Applied Sciences, where I began developing the app in spring 2026.
I’ve been fishing since childhood. These days, you’ll usually find me in a rowing boat on Airisto or fishing from the shores around Turku. I’m particularly drawn to pike fishing and the way fish react to different lures.
For me, fishing means unwinding, challenging myself and always learning. I hope to build an open community around Uistio where everyone can learn and share what they know.
I’d like to hear about your experience with Uistio. I’ll use the customer satisfaction survey results to improve the app and in my thesis.

Check the weather, air pressure trend and a weather-based estimate of fish activity. Compare conditions with your own experience; the index does not guarantee a catch.
How BiteIndex worksKeep lure names, types, colours and photos in your tackle box. Connect the lure you used with a catch so you can find it again later.
Explore the tackle boxBrowse fish species by group or habitat. Species pages bring together identification images, descriptions and a quick guide for anglers.

Uistio is a Finnish fishing app for iPhone and Android. It combines a catch diary, a tackle box, fishing spots, weather and BiteIndex with a community catch feed.
You can record the species, length, weight, photo, lure, location, conditions and your own notes. Search and filters help you revisit earlier catches. Explore the fishing log.
Your saved spots are private by default. Sharing with the community is your choice; a catch post does not automatically publish its exact coordinates. Read about fishing spots.
No. BiteIndex is a weather-based estimate of possible predator-fish activity. It is a planning aid, not a scientifically validated probability or a guarantee. See what the estimate means.
