Fishing logbook for UK anglers
Every catch, swimming in your own tank.
CatchTank is a fishing logbook that looks like an aquarium. Log a catch by voice, photo or a few taps and it joins your tank, with the weather and conditions saved alongside. Made for UK anglers, whether you fish coarse, game or sea.
- iPhone only
- Free to download
- No account needed to start
- Made in the UK
Not on the App Store yet. CatchTank launches in early December 2026, with optional Pro.
The idea
A logbook you actually want to open
Most fishing logs are spreadsheets. CatchTank turns yours into a living aquarium. Every fish you log swims into your own tank, so your season looks like a collection you built, not a list you filled in. Collect species, earn badges and look back on the year in style.
Know the conditions
Weather, pressure, moon and river level are saved against each catch, with a conditions guide and a bite score for the day.
Fish with your mates
Follow friends, share your tank and run challenges and private leagues. Your exact spots stay yours.
What’s inside
Built for the bank, not the boardroom
Voice and photo logging
Say “two pound tench on sweetcorn” and the form fills itself in. Optional AI can suggest a species and size from a photo, only with your permission.
Your own aquarium
Watch your catches swim, collect species, earn badges and build a tank that shows off your angling.
UK fisheries
Browse fisheries with species, facilities, opening hours and day-ticket prices. Always check with the fishery before you travel.
Map and heatmap PRO
Pin catches on a map, and with Pro see heatmaps of where fish are being caught.
Challenges and leagues
Biggest fish, species hunts and private leagues with your mates. How leagues work.
Stats and Year in the Tank
See your personal bests, go deeper with advanced stats in Pro, and share a recap of your season.
Prints from the Shop
Turn your best catch into a print, poster or card, made to order and posted to you.
Safe and private
Report or block anyone, hide any location and delete your account any time in the app. Under-18s get extra protections automatically.

A look inside
The app, in pictures
These are App Store preview images. Venue names, prices, catches and angler handles in them are examples, and the app may look slightly different at launch.
How it works
Three steps
Catch a fish
Out on the bank, boat or beach, do what you do best.
Log it
Say it, snap it or tap it. The species, size, bait and conditions go in your logbook.
Watch it swim
The fish joins your tank. Share it, enter a challenge or look back on your season.
Free and Pro
Free to start. Pro if you want more.
The logbook, your tank, fisheries, friends, challenges and the Shop are all in the free app. Pro adds the catch heatmap, advanced stats, tide times, the AI daily briefing and offline map areas.

Privacy first
Your spots are yours.
- Approximate by default. Other anglers see roughly where you fished (about 1 km), never your exact swim, unless you choose to share it.
- Hide any catch. Turn location off for one catch or for all of them.
- Under-18s are protected. Their locations are never shown to anyone else.
- Photo GPS removed. We strip location data from photos before they’re stored.
- Use it signed out. Your logbook works on your phone without an account.
- You’re in control. Make your tank private, block anyone, or delete your account in the app.
- Read the full privacy policy.

Work with us
We’re looking for a few good partners

Fisheries and venues
5 to 10 pilot waters, with a weekly catch picture and a QR poster.
For venues
Angling clubs
A private club league for one season, set up with you.

Questions
Quick answers
Is CatchTank free?
It’s free to download and the core logbook is free: log catches, keep your tank, find fisheries and join challenges. CatchTank Pro is an optional upgrade for extras like the catch heatmap and advanced stats.
When is it out, and where do I get it?
CatchTank is launching on the App Store in early December 2026. It isn’t available yet. See the download page, or email hello@catch-tank.com to ask about early access.
Is there an Android version?
Not at the moment. CatchTank is for iPhone only (iOS 15 or later). We aren’t promising an Android date.
How is my location handled?
Other people see only an approximate area of about 1 km by default, never your exact swim. You can hide the location of any catch, and GPS data is stripped from photos. If you’re under 18, your locations are always hidden. Read the privacy policy for the detail.
Coming to the App Store in early December 2026
