  • Phil Traut ᯅ @SpatiallyMe

    I turned iPhone Duo into a real-life notebook where you can type anywhere in your own handwriting or with one of 12 fonts I designed myself. Type or draw, then close it. The next time you open the book, it shows your most recent note or the one captured nearest to your current location. (Great for restaurant notes!) Available on launch day, hope to share more soon. DM me for a TestFlight.

choclift

@SpatiallyMe · Utilities · Launch day

Desk clock and Mac Touch Bar at once: launch Mac apps and shortcuts from the phone.

iPhone Duo can now be a beautiful desk clock AND a Mac Touch Bar at the same time. Open apps, shortcuts and websites on your Mac from our signature chocolate bar, unfold it into a full praline box or partially fold it for our all-new clock mode. We’ve worked incredibly hard for months on remaking choclift for the Duo (even before it was announced) and it feels surreal to share that it's available for free on the App Store now.

  • fugazi.md @fugazidotmd

    Why you didn’t invert the inside panel to keep the continuity from outside to inside with Apple Duo transition?

  • 360Apps @Mohamma98127565

    Thats what we are debating. Doing this makes sense on Duo but messing up ipad layout. And also it feels unnatural. MIght just make another variant & let user choose the layout.

  • fugazi.md @fugazidotmd

    Duo is not running on iOS and iPad on iPadOS ? Yeah great idea to let the user choose! Best for xp. Anyway thanks for your answer !
