DevicesNovember 1, 20261 min read

Seoul's city health app 'Wristdoctor 9988' has passed 3 million users. The city is also adding new features and events to help people stay active and manage their weight.

App Reaches 3 Million Users

The Seoul city government says its smart health app, Wristdoctor 9988, now has 3.03 million total users as of the 30th of last month. The number has grown more than three times in 2 years and 4 months. The city plans to expand health programs for residents and add new app features.

Key Numbers

Total users: 3.03 million (as of last month's 30th)
Seoul walking rate: 69.0%, versus 49.2% national average (19.8 percentage points higher, 1st among 17 regions)
Adult obesity rate: fell from 31% in 2024 to 30.2% in 2025 (down 0.8 points, the largest drop among 17 regions)
Walking event on the 5th: about 4 km, with 3,000 points for each finisher

Why Health Data Matters

The walking and obesity figures come from the Korea Disease Control and Prevention Agency's 2025 Community Health Survey. Obesity is measured partly by BMI, or body mass index, which compares a person's weight to their height.

What to Watch

Walking event 'Walking Event Day' at Yeouido Hangang Park on the 5th: about 4 km, free, 7,000 spots first come, first served, sign up by November 4 at 6 p.m. on Seoul's public reservation service
New 'Healthy Weight Management Mode' in the app starting the 9th, with target weight, BMI tracking, and suggested meal plans
Vouchers of 50,000 won for 3,000 citizens with a BMI of 30 or more, for gym and sports facility use, applications open in the app from the 9th

Why It Matters

The city says healthy habits are taking root among residents. Officials hope that regular exercise and steady weight control will help people stay healthy before illness starts. The new features and rewards show how Seoul is trying to turn an app into everyday health support.

Keyboards of The Verge

The Verge asked its staff which keyboards they use, and the answers ranged widely. NuPhy, Keychron, the Apple Magic Keyboard, and the Kinesis Freestyle split came up often, alongside odder picks. Senior reporter Jay Peters uses the Kinesis Freestyle Pro after wrist pain led him to try ergonomic keyboards.

I built an AI Tamagotchi before Meta could

The Verge's Sean Hollister spent $50 on a Waveshare ESP32-S3 1.75C touchscreen pendant, an officially sanctioned Meta "Muse Gadget" devkit, and used Claude Code to add features Meta's build lacked. These include a conversation history page, a British AI voice from ElevenLabs, a remote camera viewfinder, extra avatars, and a Tamagotchi-style minigame. He instead built a DIY version rather than buying Meta's $50 Muse Charm.

Touchscreens everywhere!

The Verge's David Pierce shares his weekly Installer No. 150 roundup of gadgets, apps, games, and media he recommends. Highlights include the new iPad Mini, the $200 Alexa Photo Frame, the nvAlt note-taking app's first update in years, and the Chromagraph camera app. He also flags the $1,700 Matic Serene robot vacuum as an absurdly expensive product.

I took two iPhones on vacation. The Duo won me over.

A tech reporter took Apple's new iPhone Duo, a loaner from Apple, on a five-day vacation alongside their iPhone 17 Pro Max. Despite early frustrations with the small outer screen, unoptimized apps, and a Google Search app that repeatedly froze, the reporter grew comfortable with the Duo, which survived sitting on and several drops onto hard floors without breaking.
