I would love for someone to make a birding/citizen scientist app that's well gamified. This is basically pokemon. You go places and find different creatures and collect them.
For those interested in birdwatching, I also recommend checking a web app: https://adsb.exposed/?dataset=Birds

I would love to play that game, and the data could maybe be useful for researchers.
On the other hand, people playing Pokemon GO trespassed private property and protected spaces, so I wonder how far would the players of this game go just to make a pic of a "legendary" animal at the border of extinction.
iNaturalist is great for logging observations (their iNat Next app is their new one).
They also have an app called Seek that I think is more aimed at kids, but it comes with trophies and streaks and stuff like that.
I had the same idea a few years ago. Would be really great.
