What's New in Breathable Air Quality Widget

4.5

October 6, 2026

This release is focused on making Trends smoother and reducing unnecessary storage of historical data. On first launch on each device, Breathable may spend extra time processing Trends. This is a one-time optimization. Syncing & Chart Performance * Fixed a bug where readings synced from other devices could disappear from Trends. Readings hidden by this bug return automatically after first-launch processing * Trends keeps full 15-minute detail for the last 30 days and now thins older readings in stages. This has no material impact on how your history is visualized, but it keeps Breathable's database small on every device and in iCloud, and improves chart performance * The Week chart now shows hourly averages and the Year chart shows two-day averages. Week is smoother without losing clarity, and Year is far more detailed. The average AQI is now weighted, so gaps in data no longer skew it * Trends no longer jumps back to "now" or stutters while readings sync in the background * The current AQI shown in widgets and Trends now appears in your history immediately, even if a different device fetched it and had yet to sync it to the history database. Previously, it could lag behind until iCloud sync caught up * The "Processing Trends" bar now stays up until processing actually finishes Other Improvements * The syncing indicator in Trends now appears above the chart controls on iPhone * Apple Watches now get unique identifiers in the Trends device list * The Release Notes archive in Help Center now always shows the current version

Updated too frequently?

I do like this app a lot and the recent redesign has made it so much better. Though my only complaint is that whenever I open the app I have to dismiss a “what’s new” modal because of how frequently this app updates.

Hah, thank you and fair point! I promise to slow down on the updates, especially now with the most recent release. Thanks for your support!

Great Additions in v4

I’ve used this widget for years and loved that I could keep it simple. Now, I appreciate the additional features (trend line, especially) and that I still can keep the simple small widget for a glance at the air quality, plus have a bigger one on another screen for when I’m wondering when it got hazy or smokey outside.

Thank you so much for the kind words and review, it’s feedback like this that makes it all worthwhile.

Better and better

I’ve had Breathable for about 3 months. During that time, the app has gotten better and better. From fixing bugs to better interface updates, to customizing how you want your widgets to look, the app has proven very useful.
Take the time to carefully setup your location. Once you get that done, everything else just flows!

I feel like I should pay for this app

While initial setup (to get API keys) isn’t zero effort, it does allow several data sources for air quality. The app otherwise seems perfect and it really feels like I should at least give the devs some coffee money.

Response from developer

What a kind thing to say, and thank you! We're glad you like the app and we appreciate the sentiment so much, but would urge you instead to donate that coffee money to the various climate change initiatives linked in the Resources section of Help Center in the app. Thank you again for your review!

Fantastic update

I’m very glad to see the update, it’s so much more useful now. No wonder the old version was being neglected a bit.

Response from developer

Updated: So glad you were able to update and the app is more useful! Appreciate you. Original Edit: I see this was on version 3.0.2, which I appreciate. But I've released version 4.0 which should resolve all of your issues, and adds new services as well.
