The first batch of iPhone Duos are out in the wild, and a bunch of app developers are finding ways to make the most of its foldable design. Perhaps the weirdest so far is Toastie, a game that essentially turns your $2000 device into a grilled cheese maker. Add some ingredients, close the iPhone Duo, and toast your creation to perfection.
We turned the iPhone Duo into the world’s most expensive toaster 🥪
Build the sandwich quickly, then close your Duo to toast it. Don’t burn it though!

It costs $3, less than an actual grilled cheese, and for that you get “10 orders, 3 loaves, and 14 things to put between them.” Your crispy masterpiece then gets a star rating for the recipe, plating, toasting, and preparation time. You can also play on iPhone and iPad without the cute close mechanic if you’re more interested in browning wheat-based products than you are fooling around with a hinge.
The game is the work of Tom Szykulski and Cyprian Brytan, and they say development took place “over more evenings than either of them planned.”
Apple revealed its first foldable phone, the iPhone Duo, back in September. If you’re waiting on your delivery, check out our list of the best iPhone Duo cases while you wait.
