CastLog - the fishing log that does the hard part for you
Photograph your catch and CastLog identifies the species, estimates its weight and length, and saves it to your private fishing diary. Built for anglers on British and American waters - rivers, stillwaters, canals and the coast.
AI fish ID is free - 10 identifications a day, no subscription needed.
KEY FEATURES
- Free AI fish identification: snap a photo and CastLog names the species and estimates size, powered by Claude Vision
- Your private fishing log: catches, weights, baits, methods, conditions and photos in one tidy diary
- Personal bests: automatic PBs by species, water and method
- Catch trends & stats: see what's working - bait, conditions, time of day
- Free AI Trip Planner: pick a water and a day and CastLog builds a full session plan - best fishing windows, ranked tactics (species, bait, method, rig), a tackle & bait list and tips, from your log and the forecast. Save plans to review later
- Real UK & US waters: look up thousands of named rivers, lakes and reservoirs
- Conditions at a glance: weather, pressure trend and river levels for your spot
- Community: share catches, browse the leaderboard, read and leave spot notes
- Works offline: log at the bankside with no signal; it syncs when you're back
WHY CASTLOG
Most fishing apps are either a cold spreadsheet or a noisy social feed. CastLog is a fast, beautiful diary that quietly makes you a better angler - snap, save, and get on with fishing.
FREE
CastLog is free. AI fish identification is free - up to 10 photo IDs a day. AI trip plans are free - up to 3 a day. Catch logging, your diary, personal bests, stats, offline logging and the community are all free and unlimited. No trial to start, no card, no catch.
CastLog Pro (optional) raises the daily AI limits and helps keep the app going. A 7-day free trial is available on monthly or annual Pro.
PRIVACY
Your catches, photos and notes are yours. Photos are only sent for AI identification when you tap Identify, and aren't used to train models. We don't sell your data.

Log catches from any date.
Add fish you caught last week, last season or years ago — just set the date and time when you log them.
CastLog fills in the real weather from that day automatically: air temperature, pressure, wind and conditions, pulled from historical records going back decades.
Adding an old photo from your camera roll? CastLog reads the date from the photo and fills it in for you.
