Casto is a smart fishing logbook for anglers — record every trip, identify fish species with AI, check tides and prime feeding times, then share your catch with the community.
KEY FEATURES
• Fishing logbook
Save every session with photos, species, weight, length, bait, technique, weather, and location. Your data lives on your device and opens instantly — even offline.
• AI fish identification
Snap a photo of your catch and Casto suggests the species in seconds, so your logbook stays accurate.
• AI fishing assistant
Ask anything about bait, technique, tides, or fish species — the assistant answers in the context of your trip.
• Tides & prime-time forecast
See tides by the lunar calendar, moon phase, and the hours when fish bite hardest, plus a 7-day weather forecast so you can pick the perfect day.
• Angler leaderboard
Compete by total weight, number of trips, or biggest catch — weekly, monthly, or all-time.
• Fishing community
Follow other anglers, like, comment, and share your catches. Spot locations are blurred on public posts to keep your favorite spots secret.
• Stats & spot map
Track your fishing journey with stats and manage your own private fishing spots.
Casto is free. Privacy first: no ads, no tracking, no data selling.
