Account
You don't need an account to fish — plans, weather and fly cards all work without one. Signing in adds: your fly box saved to the account, session log backed up and synced across devices.
No passwords — we email you a link.

Units
How depths, leader lengths and temperatures are shown. The advice itself doesn't change — just the numbers on screen.
Install the app
Put LoughLogic on your home screen — full screen, offline-ready, one tap from the bank.
How to installTell Alex
This app is built by one fly fisherman and improved by the people using it. Goes straight to him.
Sends: this page, app version — never your location.
Your data
Session logs and catch photos are private by default — only you can see them.
Sessions, catches, measurements, fly box and personal setup details as one JSON file. Photographs are excluded. Sign in for catch backup; use Back up & restore in Creel for personal fly photos.
One-tap delete is coming in Phase 3. Until then, email us and we'll remove everything by hand.
App not right?
If the app looks stale or broken after an update, refresh its stored data. Your saved plan, fly box and settings are kept.
