Fishtechy3.5.2 - App Store

Measure fish from your phone. Position a Proof Ball next to your catch, take a photo or video, and upload it to the free Fishtechy(R) app. AI measures your catch's length, girth and estimated weight, identifies the species, and creates a private digital journal - all in seconds.

Proof, Not Guesswork
No board, no tape, no guessing. A Proof Ball or Proof Bar in frame is all the app needs. Snap a photo or record a video and the numbers are waiting when you're done.

Reduce Fish Handling
Measure it. Release it. Faster. Less time out of the water means a healthier fish and a healthier fishery - a practical addition to any angler's gear, from bass boats to fly rods.

The Most Accurate Way to Digitally Measure Fish
Proof products give the AI a known dimension to measure against, so length and girth are verified measurements, not estimates. Weight is calculated from length and girth and always labeled as an estimate. Used correctly, nothing on your phone measures a fish more accurately.

Support Conservation
Every catch can count for science - only if you say so. Choose to share your catch data anonymously, without precise location, with vetted fisheries science organizations like NOAA to help protect the waters you fish. Never automatic, and you can withdraw at any time.

Digital Journal & Automatic Species ID
AI identifies your fish and logs species, size, location, time and weather to a private digital journal and map of your catches. No manual data entry. All your catch data in one place.

Online Contests & Challenges
Create or join fishing tournaments using your real catches. Compete privately with friends or publicly with anglers around the world. Catches can be scored as a percent of their world record, so you can compete fairly even when you're catching different species. Real catches. Digital leaderboards.

For Your Whole Trip
Fishtechy’s Story Mode tracks your entire trip, including miles walked or floated, a map of your route, elevation gained, and fish caught along the way. Track the whole trip with the

Fishtechy app
Your Data, Your Call
Your catch data stays under your control. Nothing is shared with scientists or anyone else without your explicit consent.
