I gave it. 1 star but am now back with a 3 star because I figured out how to get it working. For a paid app, I don’t feel like I got my $2 worth to see how cats and dogs see color. The only lens unlocked for free is fly vision. The app’s interface isn’t good. It led me to believe I could take pictures with it, with the animal vision filter on. You can’t. You can use it to view through your camera lens as that animal but you have to screenshot if you want to save how it looks. There’s a photo icon on the left and you can apply animal vision to anything in your photo library. But you can’t save it without screenshots. The minimal interface has a prominent share button but you can only share a link to the app. Sharing photos with animal vision applied is what I’d expect. Lastly, the bottom nav of animal names is confusing. If it’s grayed out, that’s your active animal but what’s centered under the button that looks like it’s for taking pictures is not always the animal you have selected. Good idea to show how animals see — but this app is not intuitive and feels broken when you first use it

Ok fly is an interesting choice I will admit for the free animal choice.So I hit dog, it said 99 cents. I saw the same poor reviews you did but decided they didn’t like the pay part. So I hit buy and got the dog part.I dunno. It’s less blue? More yellow? It is just a filter that I’m betting is already in my iPhone. I may play with that to see if I can duplicate it.2 stars for now.I know me, I’llPlay with it more. If it gets better I’ll update this. I can’t say 1 star because they asked for payment for an app. But if I find an identical setting on my iPhone I may just do that anywaySo DL at your own risk

$2 for the filters?? Fly isn’t even interesting! Totally not worth the storage or time that i wasted with this app. Don’t buy please!

Kinda sad they put a pay wall all you get is fly, they could have put a vision people actually want
