AnotherBall Is a Gold Sponsor of iOSDC Japan 2026!
Hi there! We’re the mobile engineering team at AnotherBall.
AnotherBall is a gold sponsor of iOSDC Japan 2026! You’ll find us at Sponsor Booth A, so please stop by. You can build an avatar in Avvy and walk away with an instant photo of it 😊.
On Saturday, September 12 at 17:15, RIO (@rioX432) from our team is also giving a Rookies LT (lightning talk). We’d love for you to catch it!
Event Details
- Official site: iOSDC Japan 2026
- Dates: Friday, September 11 – Sunday, September 13, 2026
- Venue: Ariake Central Tower Hall & Conference (Google Maps)
Our booth is open all three days!
We Build a Live Streaming App Called Avvy
We build Avvy, a VTuber avatar and live streaming app: build a 2D avatar on your phone alone, then start streaming with no camera and no gear. You combine 2D illustration parts into an original avatar, and the phone camera tracks your face and expressions to drive it. Viewers send gifts during a stream to cheer the streamer on.
Business logic is shared between iOS and Android through Kotlin Multiplatform (KMP), and avatar rendering runs on Unity as a Library (UaaL). A game engine and native UI share one app, so we hit walls a typical native app never runs into, and we’re wrestling with them every day.
RIO’s Rookies LT
On Saturday, September 12 at 17:15, RIO (@rioX432) takes the Track A Rookies LT stage with Why Is “Puffing Your Cheeks” Tracked So Accurately? (talk in Japanese). Don’t miss it!
Our iOSDC Token Is on the Flyer
AnotherBall is taking part in the iOSDC Challenge, the annual token hunt. Collect the iOSDC tokens placed around the venue and in online content, and the more you collect, the more raffle tickets you get for novelty prizes.
Our token is printed on the flyer we hand out at the booth. Come grab one!
Build Your Own Avatar at the Booth
Besides chatting with our staff, you can build your own avatar in Avvy right there at the booth!
Pick a hairstyle, then eyes, then an outfit, and you have your own avatar. Switch to camera mode, make whatever face you like, and take a shot. We print it as an instant photo and slip it into an original-design name card holder for you to take home!
The whole thing takes about five minutes. If you’re short on time, we’re just as happy if you drop by only to pick up a flyer and a sticker!
Come Talk Shop
Posts the mobile team has written so far.
- Embedding UaaL in a SwiftUI App: Managing the View Lifecycle
- Mobile App Development with KMP × Unity UaaL ── Multi-Repo Setup and Automation
- KMP × Kotlin 2.3 ── How Android Got Slower While iOS Builds Improved by 47%
If any of them catch your eye, come find us at the booth.
We’d love to talk about how we embed Unity in a native app, or how we handle the real-time side of live streaming. Conversations like that with people who find this stuff interesting are the best part of any conference for us. Our engineers will be waiting for you at the booth!
