App development iOS · Android mobile app development company
Building an app is the easy part. Passing review, shipping updates continuously and keeping users from deleting it is much harder. We handle store release and operations too.
When to bring this to us
If any of these applies, it is time to consider App development.
- You need push notifications, camera or location — things the web cannot do
- You already have a web service and want to ship it as a mobile app
- Field staff need a work app (inventory, delivery, inspection records)
- Your app keeps getting rejected by the App Store or Play Store
App development: what we build
Pick only what you need. We do not pad the scope with features you will not use.
Native app · hybrid app
Native when the app uses device features deeply — camera, Bluetooth, background location. Hybrid when there are many screens and content is shared with the web. We decide by what the app needs and your budget, not by trend.
Accounts · login · social login
Email sign-up plus Kakao, Naver, Apple and Google login. On iOS, adding social login means you must also offer Sign in with Apple to pass review — we handle rules like this for you.
Payments · in-app purchases
Physical goods go through a payment gateway; digital goods and subscriptions go through store in-app purchases. Digital goods sold through external payment get rejected in review, so we separate them in the initial design.
Push notifications
FCM-based push for individual, broadcast and conditional sends, controlled from the admin. It is the strongest way to bring users back into the app.
Maps · location features
Nearby search, routing and real-time location sharing built on map APIs.
Admin panel · store release
An app alone cannot be operated. We build the web admin for members, orders, content and stats, and handle App Store and Play Store registration, review responses and update releases.
How we proceed
From estimate to contract, schedule and maintenance, everything is tracked transparently in our own system.
