Huff update: The Light Bringer quest, plus crash and battery fixes

Quests are a new kind of challenge in Huff: a set of steps that add up to one reward. The first is called The Light Bringer, and it's the hardest thing we've ever put in the app.

The steps are hard, and if you complete them, you truly deserve the reward. It stays sealed until the very last one is done.

You'll find the steps in the app: open Huff and tap The Light Bringer on your Home screen. Some of you may be closer than you think.

The doors used to close a full minute before a Breathe Together session began. Now you can join right up to 15 seconds before the first breath.

When a session is a few minutes away and people are already in the room, a Join card with a live countdown appears on your Home screen, so you can see exactly how long you've got.

And if you host your own session, you can now choose 3, 6 or 10 rounds, or any number you like. Friends you invite join for free.

If your iPhone runs iOS 15 or 16, Huff may not have opened at all for a while. That's fixed in this version. I'm sorry if you were caught by it, and if it made you give up on Huff, now is a good time to come back.

Huff was also using more battery than it should, even when you weren't using it. That's sorted too.

And we've fixed a crash that could happen as a session started.

• Journal prompts: a short writing exercise that turns up on your Home screen
• Message us from inside the app: chat with the team, send a photo, and get the reply right there
• Full moon badges to collect
• Lots of smaller fixes, including Focus Trainer and the keyboard on Android

Saturday 10 October is World Mental Health Day. Every session in Huff is free all day, and we're breathing together at 10pm UK time. Come and fill the room. Quest hunters, this one might be worth your while.
