What's New in Manta Ray Tracker

2.0.1

July 4, 2026

There is now a new "Identify" feature! Provide the App with an image that includes a Kona Manta Ray, and it will use Machine Learning to try and identify which of our Kona Mantas it is. You will be shown a list of up to 3 possible individuals it could be with the percentage of probability. Use this information to tag your images in your sighting reports! The App is NOT 100% accurate so you will have to verify the identification on your own. The higher the number of images we have of an individual manta, the more likely the App will provide a correct result. So be sure to send us your great "ID" sighting images, *especially* if it does not accurately predict the correct individual. All of the processing happens on the device, no network connection required. This means you can also use the App's Camera functionality to take a picture underwater, (let's hope you also have an underwater housing for your device first though) and you will know on your dive or snorkel which manta you are in the water with!

Mantas

I want to find Manta Rays in my area BUT it just goes to Honolulu!! I’m in the Mediterranean Sea and I want to save them here, the problem is that only Honolulan ppl can see so this is considered USELESS!! (except for Honolulu).

Response from developer

You are quite right! That's why the App says it is only for the mantas of "Kona, Hawaii". (Which is nowhere near Honolulu just FYI). We get millions of tourists from around the world coming to Kona, Hawaii to see the Kona manta rays. I suggest if you want to "save manta rays", you contact a local organization in your area or somewhere closer to you that studies Mobula rays. Would appreciate you changing your review to accommodate your mistake. Thanks!

Fantastic tool for citizen contributions to science

Great tracker for the mantas on the Kona coast. If this tool was utilized more in our community we would have a better understanding on the movement ecology of our Kona mantas.

View and report manta sightings!

App gets the job done and lets you view and submit manta sightings so the manta pacific research foundation can better understand their numbers and behavior patterns. Mantas are amazing 11/10 would manta again!
