Fish identification with no signal
Offline fish identification means the species model lives on the phone, so a photo is identified without uploading anything. CatchVault works this way: species ID runs on the iPhone in seconds, with or without a connection.
Where cloud ID fails
Mountain lakes, canyon rivers, big reservoirs away from towns, offshore water and most of the backcountry have weak or no coverage. A cloud identifier has to upload the photo, wait for a server and download the answer. On one bar of signal that either takes a long time or never finishes.
The trade-off
A model small enough to live on a phone has to be focused. That is why CatchVault concentrates on species found in North American water rather than every fish on earth. For anglers in the US and Canada, that focus is the useful kind.
A side benefit: your spots stay yours
When identification happens on the phone, the photo does not need to leave the device to get an answer. For anglers who guard a good creek, that matters.
Questions & answers
Does CatchVault need internet to identify a fish?
No. The identification model runs on the iPhone.
Is offline ID less accurate?
Not for the species it was trained on. The limit is coverage, which is why CatchVault focuses on North American fish.
