CatchFolio: Fishing Log

About

Turn each outing into a structured field record. CatchFolio is a free, local-first tool for anglers who want more than a loose diary. Plan a field run, append numbered observations while it is active, seal the ordered record when it is complete and preserve later clarification as a visible correction. BUILD A FIELD RUN • Set an objective, target species or question • Link a private water profile • Record launch or access reference, party size and safety brief • Move deliberately from planned to active to sealed APPEND WHAT HAPPENED • Add numbered observations, effort intervals, rig changes, catches and safety observations • Link an event to a working zone and rig card • For catches, add your own species label, outcome, measurement and lure or bait • Keep zero-catch and zero-event effort in the run history PRESERVE THE RECORD • Sealing generates a local digest from the run and ordered events • Sealed events stay read-only • Corrections are appended with their own timestamp while the original remains visible • The Evidence Ledger shows seals and correction chains together BUILD A PRIVATE WATERBOOK • Save manual access references without requesting device location • Record observed hazards and named working zones • Keep every profile private unless you choose an export destination REUSE COMPLETE RIG CARDS • Record rod, reel, mainline, leader and terminal setup • Track consumable stock and service dates • Use optional on-device service reminders EXPORT AND RESTORE • Export the complete schema-v2 JSON evidence record • Export one CSV row per ordered field event • Create a readable text record with seals and corrections • Validate structure and links before a backup can replace local data FREE MEANS FREE Every CatchFolio feature is available without a paid download, in-app purchase, subscription, trial or paywall. The app is supported by advertising. A rewarded ad is always optional and changes only a temporary decorative deck colour; it never unlocks a record, export, limit or tool. IMPORTANT BOUNDARIES The local seal is an integrity aid, not a digital signature, third-party timestamp or legal certification. CatchFolio does not provide forecasts, navigation, public fishing spots, automatic species identification, regulations, legal bag or size limits, or water-safety advice. Check authoritative local sources before fishing. Create a field record you can inspect, correct and keep.
