We’ve updated our CloudSpotter AI cloud identification tool to help you discover what clouds and optical effects you’re spotting! • CloudSpotter AI is now better at recognising rare and unusual cloud formations, not just the obvious ones. • It can now include more cloud types and optical effects in its results when it detects them in your photo. • We’ve improved the look of the page you see while waiting for your CloudSpotter AI result. • We’ve also gently brushed aside a few little bugs we found in the CloudSpotter AI pages.

This minor update includes some behind-the-scene work and a few text and design tweaks: • Updated how the CloudSpotter AI is accessed by the app to pave the way for an improved AI that will be included in a forthcoming update. • Added new text to the 'Don’t Confuse With' section of clouds and optical effects in the Cloud Library. • Improved the text styling in the info to help you vote on clouds in the Sky Feed. • Tidied up a few minor design issues.

We have fixed a bug relating to contributing your spotting on Cloud Appreciation Day.

We’ve updated the nav bar icons. We've added the ability to submit contributions during special events. For instance, you’ll be able to share your sky with the world on Cloud Appreciation Day (September 12th 2025). We also sent a couple of bugs on their way.

In this update: • A new Permissions screen where you can agree to receive notifications about things like Cloud Appreciation Day 2026, on Friday 12th Sept, when you’ll be able to contribute your sky to the international Memory Cloud Atlas, and (in the future) when your spottings have been verified by the community. • Improvements to the flow for spotting a cloud. • Some bugs have been gently brushed off into the coding undergrowth.

In this update, we’ve improved the New Spottings module, where you vote (with our help) on whether other CloudSpotters spotted their clouds correctly. Changes to New Spottings: • You can now see the username of the CloudSpotter whose image you’re voting on. • The text for the spotting details now appear below the image rather than over it. • After tapping a spotting so you can pinch and zoom it full-screen, you can now see its details and vote on it without having to exit the full-screen view. • And remember, you can always scroll down the New Spottings page to see reference images and helper text relevant to the spotting you’re cast your vote on. In addition, we’ve also gently ushered a few bugs off into the coding undergrowth.

In this update, we’ve introduced CloudSpotter Stars and improved the accuracy of the moderation process: • The cloud types and optical effects that you can spot now have Star values, depending on how rare or difficult they are to spot. Common types like the Cumulus cloud or rainbow earn you 1 CloudSpotter Star. Rare ones like the fluctus cloud or Circumzenithal arc will earn you 5 CloudSpotter Stars. • The Cloud Library now shows the Star values for all the types – as well as which ones you’ve already spotted and which you’ve yet to add to your collection. • Your CloudSpotter Stars total shows in the header panel of My Collection. • If you earned Stars in our legacy CloudSpotter app, these have been carried over and will appear in your total. • The more CloudSpotter Stars you have, the more weight we place on your votes on the New Spottings by other users. • We’ve improved the accuracy of the moderation process. Our own expert CloudSpotter Moderators will now step in to pass verdicts on any spottings that the community as a whole can’t agree on. • Oh, and we’ve fixed a few bugs along the way.

• The Cloud Library now shows which clouds and optical effects you’ve already added to your collection and which you’ve yet to spot. • We've fixed a bug causing the wrong total to show for Types Collected. • To ensure all spottings are legitimate we now accept only those photographed through the app.

This version introduces the following: • Viewing spottings submitted by other users and voting on them. • Ability to submit spottings in existing collection for verification by the community. • New spottings automatically are submitted for verification by the community. • A Cloud Karma scale nudges users towards voting on the spottings of others in addition to submitting their spottings. • Ability to change username. • Ability to delete account and data. • Bug fixes and UI improvements.

New features: • Delete unwanted spottings • Swipe between your spottings • Jump from a spotting to the relevant entry in the Cloud Library • Performance improvements and fixes

Try out our new and improved automatic CloudSpotter AI identification! It can now recognize the more rare and unusual cloud formations as well as many of the optical effects produced by clouds. Is that a lenticularis cloud or an undulatus? A lacunosus or radiatus? Snap a photo and let the artificial intelligence tool tell you what you’ve spotted. This update also includes various bug fixes and behind-the-scenes improvements.

Minor UI improvements and fixes

Fixed an issue with the Cloud-a-Day stream for guest users

We've squashed some bugs and made improvements to the design.

You can now create a Cloud-a-Day account and start building up a collection of your own spottings!

2.1.1: Bugfixes and improvements 2.1: Try out the beta version of CloudSpotter AI, our automatic cloud identifier. It is trained to recognise the ten main cloud types. You can access it from the lightbulb button in the Cloud Library. Want to know which of the ten main types our artificial intelligence system thinks you are spotting? Just upload a photo, and use the cloud to identify your cloud!

We have fixed the auto-refresh of the Cloud-a-Day timeline. Drag and release to refresh it manually after which it will automatically fetch the latest clouds. We've previously added a Cloud Library of 58 clouds and optical effects and a question-and-answer Cloud Identifier to help users work out which formations they are spotting.

User interface refinements

– Improved app-loading experience: you will now land directly in the cloud timeline! – Better photo zoom functionality: pinch to zoom in or out and pan to explore all clouds in detail.
