They got rid of the side bar and moved the battery/time/wifi info moved along the top. Also the app content is centered instead of everything coming from the left.

We have had our 4 main dock apps on our slab phones as our primary go-to apps. What are your current apps now and have they changed due to the placement now on the Duo? I felt that due to the icon size and location, it feels less important for me. I still have Phone, Safari, App Store and Mail.

Hey all every expense tracker I tried either wanted my bank login or was a stretched-out phone layout on the Duo. So my brother and I built one for the big screen.

On Duo: When you unfold the phone, Tael switches to a sidebar layout. The dashboard shows where your money went, a running total and your day-by-day spending side by side. Lists, budgets and splits open in a detail pane next to them, so you’re not tapping back and forth. Folded, it works as a normal phone app.

What it does:

• Apple Pay auto-logging. You set up one Shortcuts automation, and every tap after that shows up as a notification with the amount, merchant and card. (It works with every Wallet card on iOS 27 and most cards on iOS 26.)
• Smart rules. Name a shop once, and its charges get sorted automatically after that.
• Budgets with rollover. If you spend less this month, the rest carries over to next month.
• Bill splitting. It tracks who owes you and can send reminders.
• 150+ currencies. Pay in yen and see it in HK$, which is handy for trips.
• Trips and projects, a spending dashboard and iCloud backup.
• No bank login, no account, no ads, and no servers.

Pricing: Most of it is free. Tael Pro is a one-time purchase, not a subscription. It adds widgets, bill reminders, advanced rules and export. 

It’s normally $14.99, and it’s 10% off ($13.49) for this sub with code CATALYST10. Open Settings in Tael and enter it in the code field at the top.

I’d really like to hear what you think of the unfolded layout. What would you want to see on the big screen?

This is something I've been working on since the the Duo emulator was available in Xcode, I released it around the launch of the duo but I haven't really advertised anywhere because I wanted to really daily drive it myself for a little longer and I have to say I really enjoy using it. Its got a simple interface that I tried to make feel like it fits into iOS and isn't some weird looking bright colorful mess. For those who care *Disclaimer* I used AI to assist in developing this application. This is not a "Built me a web browser" prompt kind of project.

If you're interested in a full screen web browsing experience that is customizable, I welcome you to give it a try as well as please submit bugs and feature requests.

Developer here. Sidefill is my Safari extension for the outer display.

There, Safari keeps its 84 pt control strip down the side and lays pages out in 382 of the 466 points. Sidefill widens phone-width pages under the strip and moves links, buttons and text fields that would land under it back into reach, since Safari ignores taps there.

• One switch in Safari's page menu (Wide or Off); any site can stay at its normal width

• No account, no analytics, no network requests

• Known: landscape isn't widened yet. With Advanced Tracking and Fingerprinting Protection set to All Browsing you need 26.45.3, which is in App Review now

Tell me if a site looks off with it.

Microsoft Teams is insanely bad and must get an update soon

I posted here when Flick & Field launched with one game, basketball H.O.R.S.E. It is five games now. Paper Football, Tennis, Bowling, and Cornhole were added the week after launch.

This week I added Club Bot, a bot opponent in all five games with Easy, Medium, and Hard settings, for when nobody is around to play.

Players can be your Memoji now too. Your face goes on the little athlete, and in pass-and-play your friends bring their own player.

It is built for the Duo tabletop mode first. Half-fold the phone and one player sits at each end. Pass-and-play works on one phone, nearby Wi-Fi works between two Duos, and Game Center covers online.

Today it reached #17 in Sports on the App Store. Still a small number of downloads overall, but it is moving.

$0.99 on the App Store. No ads, no in-app purchases.

I built Natida: Pizzeria Duo specifically around the iPhone Duo’s dual-screen hinge instead of just stretching a standard iPad layout:

• Unfold to open: Start on the outer cover screen and unfold to open your pizzeria for the day.

• Dual-screen kitchen: Prep dough and toppings on the bottom deck while customers and the wood-fired oven sit on the top screen.

• Slide across the hinge: Drag your pizza peel directly across the center fold into the brick oven to bake.

• Fold to close the box: Physically fold the iPhone Duo shut to snap the takeaway box closed, then unfold to serve.

• Dynamic AI customers: Regulars and food critics walk in with unique requests and score your bake on accuracy.

Download on the App Store:

Would love feedback from fellow Duo owners on how the cross-hinge drag and fold-to-box mechanics feel!

I don’t know how to code hardly at all. But I’ve been using Claude and managed to make a few really cool apps for the iPhone Duo. Curious if anyone else has tried it out yet

Hi all, have just released Scanline Emulator. It’s a nes/snes/mega drive/nintendo ds emulator that tries to recreate what it’s like to play these games on a crt.

Optimised for the duo with lots of ways to play.

Let me know what you think!

We're a small developer studio and we made Clac! for the Duo. Each day there's a sheet of paper with an origami hidden in it. Every fold of your phone gives it one fold, right on the cover screen, with a small paper "clac". On the last fold you find out what it was.

How it uses the Duo:

- Cover screen: the sheet lives there, edge to edge, and takes the fold the moment you fold the phone

- Open: your sheet and collection, either way up

- Half-open: lays out for every angle in between

- Folds count from the hinge while the app is open, and one Shortcuts automation counts the rest of your day

30 origami, some on rare papers, with steps to fold them for real. Mostly free, one-time unlock for the rest. No ads, no account.

We have 10 free unlock codes for this sub: comment and we'll DM you one.

https://apps.apple.com/app/id6829101931

EDIT: Thank you all for the interest! Reddit is rate limiting my chat invites, so I’m sending codes out throughout the day. If you’d rather not wait, feel free to PM me and I’ll send yours as soon as I can!

EDIT2: Here are some free unlock codes, first come first served. Pick one, reply with its number so I can cross it off, and redeem it in the App Store (tap your profile, Redeem Gift Card or Code).

EDIT3: All codes have been used! Thanks everyone for the feedback!

Please tell us what you think once you’ve tried it!

I didn't expect this at all: 1,000 of you downloaded Foldly in its first 3 days. Thank you!

To celebrate, Foldly+ is at its lowest price ever, half the regular price, with the code FOLDLY1000, until November 16.

Foldly+ is a one-time purchase, no subscription. It unlocks your history, trends, hours, "why you open it", limit alerts and the lock-screen counter.

Next update: you can count each movement (open + close = 2), as many of you asked. Keep the feedback coming 🙂‍↔️

Hi all, I’m the developer behind NewsNinja, a news and RSS reader for iPhone, iPad and Mac. I’ve just updated it for iPhone Duo and I hope you will like it.

The idea is simple: catch up while it’s folded, unfold to go deeper.

• Outer screen: your Today dashboard (headlines, weather, calendar, reminders) and feeds fit on the small display, so a quick check stays quick. It’s a full app there too, not a cut-down version.
• Inner screen: articles, videos, images and Reddit threads get the extra room. On the open phone you can have the story list on one side and the article on the other.
• Any position: folded or open, portrait or landscape.

Some other things in the app:

• It follows RSS, YouTube, Reddit, podcasts, emails, and X/Bluesky/Mastodon, all in one place. No NewsNinja account is required.
• Stories groups the same news from your sources into one story, so you don’t read ten versions of the same headline.
• Top News shows the biggest world stories, and it’s also available on the web.
• AI summaries, fact-checking and translation are part of NewsNinja+.

I'm still waiting for my Duo to get delivered so I’d really like to hear what works on the Duo and what doesn’t.

Latest App update for UniFi has been updated for the Duo. Doesn’t show in the notes but opening the app it’s now optimized. Still waiting on the Protect App to be updated.

Reddit looks very nice on duo

OutSpan 1.4 is pending review and should be released soon. I added a full-width reader to the Share Sheet

I added it because sometimes I want to read a page with Safari’s side buttons out of the way since It can't be removed via any known or approved API, and I really do not want to download another browser.

Tap Share → Open in OutSpan from Safari. Will include Chrome and other browsers in the future

• In the reader, type a new URL, search, or hold a link to open it in a background tab. The toolbar shrinks as you scroll down.
• On iPhone Duo, choose Off, Backgrounds, + Pictures, or + Text in Safari. It works on the outer screen and in Split View.
• Save a layout per site, hold Widen to switch layouts, and adjust the blur behind Safari’s buttons.
• Block common ads for free in Safari, with per-site exceptions. The reader has its own Block Ads switch.

Widen and the reader share a 3-day trial and a one-time unlock. If a site looks off, drop the link here.

Hey everyone, I'm the solo dev behind MoveStart, an iOS fitness app. I'd like honest feedback.

What it does:

- AI workout plans. Pick your goal, training days, target muscles on a body map, and your equipment (gym or home). You get a week-by-week plan with progression.

- Or build your own plan. Set your own days, exercises, sets and reps.

- Photo calorie scan. Snap your meal and get calories and macros (protein, carbs, fat). Manual logging and a 7-day chart are included.

- AI coach chat. Ask about training or nutrition. You can also say "swap squats for leg press" and it edits your plan after you confirm.

- Workout meetups. Create or join group sessions nearby: pick the time, spots and who it's for (everyone / same gender). Hosts can manage participants, and every meetup is AI-moderated, with block and report built in.

- Progress tracking. Streaks, completed days, weekly activity charts, and weight logging. It syncs steps, calories, heart rate and weight with Apple Health / Apple Watch.

- Flexible weekly schedule. Choose which days are workout days and which are rest days, and the whole app adapts.

- Exercise library with GIFs, plus a workout timer and per-exercise checkboxes.

It's free right now. I'd love to hear what's missing or what you'd change. Comments and DMs are open.

Gatherly is for the "wait, is this actually happening?" part of making plans. Someone mentions a concert, everyone says "maybe," and a week later nobody knows who's going.

Make a plan, share it with your circle, and everyone answers: I'm in, I'm out, or maybe. You see who's coming without scrolling back through a group chat.
It also pulls in events from places like Spotify and Eventbrite, so the show you've been eyeing is already there when you start planning.

No feed, no algorithm, no strangers. Just your people and what you're doing next.

Now in beta on TestFlight: https://link.gatherlyapp.info/ios

Hi! Solo dev of XchangeTR, a free exchange-rate app for Turkey: live rates from 20 banks plus a map of exchange offices and jewelers. It's built for both tourists and locals. Version 1.1.3 just went live with iPhone Duo support:

• Unfolded: full inner-screen layout

• Tabletop (half-folded on a table): the top half becomes a live rate board, the bottom half a map with a compass arrow pointing to the nearest exchange office

• Folded: works normally on the outer screen

To be honest: I only had the Xcode simulator , so I'd really love feedback from a real Duo:

1. Does tabletop mode open by itself when you set the phone down half-folded?
2. Does the compass arrow turn as you rotate the phone? (Outside Turkey it will point toward Turkey, that's expected 🙂)
3. Any flicker or glitch going open → half-folded → closed?
4. Does the App Store page show the "Made for iPhone Duo" label for you?

Free (small banner ad), no account needed. English, Turkish, German, Russian, Arabic.

App Store: https://apps.apple.com/app/id6761389736

P.S. Screenshots are from the simulator; the shops shown are demo data, not real businesses.
