Behind the app
Catchline is made by Mark Hollingsworth — one angler, writing the app he wanted on the water and could not find anywhere else.

The fishing apps that grew largest did it by turning water into content: shared spots, leaderboards, a score for the day and a forecast telling you where the fish will be. Good water does not survive that kind of attention, and neither does the pleasure of working something out for yourself.
So this one keeps the oldest habit in fishing instead — a record, kept by hand, read by nobody but you. Over seasons it becomes the only honest account of how you fish. That account is yours, and it is unique to you.
Your data is not for sale. Your locations are not for sale. There is no advertising in the app, no sponsored gear, no brand pushing tackle at you between catches, and nobody buying access to what you record.
The only money Catchline will ever take comes from the anglers who use it. That keeps the app answerable to one group of people, which is exactly the point.
The same person built the app, answers the notes and edits Field Notes from Abroad each week. If something reads wrong, measures wrong or feels pushy, that is a fault — say so and it gets fixed.
