Description
ScaleScience is a fish weight calculator and digital catch log built for anglers who want accurate weight estimates on the water. Enter a length measurement, select your species, and get an instant weight estimate. Built by a fisherman for fishermen, the app lets you save and store catch info — including species, length, girth, photos, and location. Then you can seamlessly share your stats with your fishing buddies or keep it all to yourself. Fish smarter, brag better.
Key features:
- 100+ species covering tuna, bass, trout, salmon, billfish, grouper, snapper, jacks, and more. Don't see what you want? Request it
- For fisherman practicing catch and release or the one that just wants to brag, a length measurement can be used to estimate fish weight
- Save every catch in your own Cloud Synced digital log book with all of the details
- Interactive catch map to visualize where you fish and save your favorite fishing spots
- Contribute anonymized catch data to marine science research + the more you catch and contribute the more accurate our estimates are
