What's New in Version 1.1.0

New features:
• Time to clean up the Library! You can now delete spottings, so go on and get rid of any duplicates or embarrassing mistakes (we won't tell anyone that you once submitted a photo of your shoes as a Cumulus cloud).
• Night vision activated! We've enabled camera low light mode for iPhones that support it, and disabled the flash (chances are it wouldn't reach clouds 10,000 feet away). There has never been a better time to spot those Noctilucent clouds!
• Silence speaks louder than beeps: App sounds can now be disabled in Settings.

• The dreaded 111 Error is squashed. Huzzah!
• Much improved compatibility with iOS 8 and iOS 9.
• We've updated all references to the new cloud type, identified with the help of this app. The World Meteorological Organisation are accepting it as a new classification and have slightly changed our 'Asperatus' name to the new official one: 'Asperitas'. History in the making!
• Various text corrections and some clarifications to the cloud identification details.

We won't bug you in the app to leave a review, but if you enjoy CloudSpotter, it would mean so much if you would share this by rating & reviewing the app on the App Store. Thank you!

Great App but...

A great new feature is that you can delete photos from your library now that you don't want to post or were the wrong cloud. The new version doesn't record your location any more and therefore you can't collect certain badges. I'm below the equator at the moment, but don't get the according badge for it cause the location isn't recorded. Very annoying. I was looking forward to collect the badge for ages.

It's great!

I cannot describe how happy this app makes me! Have always loved the great outdoors, and cannot understand how I was so "cloud blind" before... Cloudspotter has opened up the sky for me. Thank you!
The recent update has removed the location ID. I did enjoy seeing the locations in daily global photos... But otherwise, much less glitchy now, thanks.

Latest update impression, suggestions, gripes

Although I love this app and am a long time member of the CAS, there are some things which annoy me.

1). For a very long time the app has claimed that 'soon' we will be able to zoom in on the camera, but this still hasn't been implemented. I would also like to suggest that maybe the camera could have an adjustable exposure feature.

2) I had a cloud marked as unverified in early September so I send an email to the support asking if they could check it again. I never heard back.

3) I cannot get the app to use my location. I am fairly iPhone savvy and have location services turned on etc but I always have a '-' where it should give my location.

4) I also cannot get notifications any more for when a cloud has been verified. I have tried everything as with (3), like reinstalling, checking notification centre, etc, but nothing. I find this really sad as it used to be fun getting those notifications.

I think in addition to the camera options I have mentioned, the app could also be improved in the following ways:

1) The leaderboard could be scrollable - I would love to be able to see more than just the top-ranked people.

2) There could be an in-app support feature, where any problems or questions could be submitted from your personal account and then answered by a moderator.

3) As another reviewer said (2 years ago) it would be great to be able to tag different sorts of clouds, or circle them so a moderator can see where you are looking.

4) I would be great if we could re-submit clouds.

5) The moderation does not match the description, so I would suggest either saying that clouds will be verified within a week, or making sure to verify clouds within a day. This seems to have worsened in the last year or two.

6) It would be nice if you could choose for a moderator to tell you what kind of cloud they believe your unverified spotting to be.

7) I think a good feature would be to have two kind of cloud of the day - one from the moderators and the other based on a user voting system. Perhaps that could be weekly? I think seeing what other cloudspotters think of your picture would be really fun.

8) It would be really nice to be able to comment on other photos in the cloudstream and maybe to rate them too, so that a weekly (as above) user-based cloud rating system could be implemented.

9) Now that someone has snapped all the clouds, it would be great if you could introduce more denominations of clouds, eg scud clouds, banner clouds, etc, to even things out again.

10) If the above is implemented, then maybe new badges could be introduced too. I would love that.
