Canny Customer Insights

1. Hope to see an update.The amount of filters in this app is impressive! Love that you can apply them to pictures in real time and also to pictures you upload! Definitely need a paid version with no ads though! The ads are incredibly annoying and pop up way too often!I like this app.

2. I don't have any coding skills, so I don't know what its capabilities are as far as being open source but if you can handle the 30 second ads every 15 clicks, its pretty cool.Yes! I've been traumatized since Samsung took away my favorite photo edit options a few updates ago.

3. To tweak the setup you need to switch to default camera app(pencil icon, camera) to take the picture then edit from Canny.

4. I'm lovin' it! :)The app takes pictures and applies filters in real time, the low download size is a nice bonus.

5. The camera filters are really cool if you're looking for unusual effects.

6. Yes the ads are annoying, but so are all other ads, people gots to get paid! The functionality you get for free, is well worth the agitation a full screen ad brings.

7. Its not a camera for beauty filter or that improves landscape or scenery - its specifically for unusual, artistic, mindbending effects.

8. The only feature, that is missing is video effects - understood, that its a different load, but should be doable & rather fast using NPU, popping up in smartphones.

9. And there doesn't seem to be any way to pay to opt out of ads :(The app is great, but the only problem is that some filters, which are the best among them all, are really heavy (hull for example).

10. It solves the major problem of experiencing all those image processing techniques that are hard to visualize from reading the books.

11. I haven't found any photo edit app that had all the features I was looking for.
