Customer Reviews

Great idea - needs better functionality

This app is fantastic for anyone who loves keeping their eyes on the sky. It is easy to use, fun and cheap! I've gifted this app to several friends.

However, there are a few things the developers could do that would REALLY make this app an excellent product. Here goes...
1) once you've uploaded a photo, if you incorrectly name the cloud (ie it is 'unverified') there should be either an option to 're-guess' or for the expert to say what they think it is. That way we learn as we go along!

2) the library of other people's cloudspots is great - a function to 'like' these shots would be great. This would create a social media feel alongside the badge/scoring system.

3) I understand the requirement to take and upload photos directly from the app - but please can you allow us to zoom/crop etc?

4) I agree with the previous suggestion that the table is static. Perhaps users need to be regular contributors to maintain their status.

I hope the developers take on this feedback, the app has so much potential.

One of my favourite apps

As an avid cloudspotter, the ability to snap photos of clouds, identify them and have my selection verified the same day by an expert, is awesome.

It's a nicely designed app with great photos of the different cloud types with detailed descriptions.

My only criticism is that, after some months of use the scoring system means the leaderboard gets rather stagnant. There needs to be some way of spotters moving down the leaderboard rather than languishing at the top! It would also be nice to see some sub-types included (eg altocumulus castellanus for example) but a great introduction to nephology.

Fab new cloud spotting tool

Just received my first communication from the Cloud Appreciation Society which mentioned this app. What a great idea! It's a fun, educational tool and I can't wait to start snapping clouds and uploading them. The only downside is that you cannot access your past cloud photos, which I would like to share. To get around this I have submitted a few if my favourites to the Society website, where hopefully others can enjoy them too. I'm sure this app will bring me hours of fun!!! Thanks :)
