Developing what the heart desires

A small workshop that crafts apps

We make apps the way a craftsman makes one piece in a workshop: start to finish. From a screen sketched on paper to each line of code, the store release and everything after it, the same hands do the work. Android and iOS are held to the same standard.

How we work

The name gongbang — workshop — describes the method, not the mood. Our material is code, not wood or metal.

01

One pair of hands,
sketch to release

Planning, screen design, engineering, store submission and post-launch operation are handled by the same people. Nothing is handed over, so no decision loses its reason.

02

What worked
keeps working

Every feature ships with automated tests. The whole suite runs before each release, so behaviour that used to be correct does not quietly break.

03

Checked on
real devices

Small screens, enlarged system fonts, no network at all. We verify those before submitting. Working only on a developer's machine does not count as finished.

Craftsmanship

Every line of code, shaped by hand

A workshop is not a production line. We cap the number of projects open at once, build only as much as our hands can reach, and finish one before starting the next.

Screens begin as sketches on paper. Every element on a screen, the size of a button, the length of a sentence — each is chosen deliberately, which is why we remove features more often than we add them. The code is written the same way: not assembled from borrowed parts, but only what is needed. Years from now the people reopening it will be us, so we leave code that reads clearly.

Platforms

Android and iOS, same standard

Google Play and the App Store differ in review criteria, privacy disclosure and advertising policy. Satisfying one does not satisfy the other, so we track both separately.

  • Flutter — Google's UI toolkit. One codebase, both platforms, same quality.
  • Firebase · Google Analytics — app health and usage measurement
  • Google AdMob — ad delivery and app-ads.txt publisher verification
  • Google Play Console · App Store Connect — review, staged rollout, versioning
  • Google Cloud — API key management and access restriction

Our apps

Apps we design, build and run ourselves.

Fake Call (이놈아저씨) app icon

Fake Call (이놈아저씨)

A role-play call app: a parent dials, and a character such as 이놈아저씨 or Santa answers and talks to the child. Parents can create their own character with their voice and a photo.

BeerPrice (비어프라이스) app icon

BeerPrice (비어프라이스)

A calculator that turns multipack beer prices at Korean convenience stores and supermarkets into a price per 100ml. It counts coupon discounts and can fill in the fields from a photo of the price tag.

School Rush app icon

School Rush

An endless runner: a boy who slept through his alarm races to school before the bell rings. Dodge obstacles, resist the distractions along the way and collect coins to see how far you can go.

Hangul Cryptogram (나랏말) app icon

Hangul Cryptogram (나랏말)

A Korean word puzzle: every consonant and vowel is hidden behind a number, and the same number always means the same letter. Use that one clue to complete 1,000 Korean sentences. The puzzles are in Korean.
