From everyday tools
to long-run brands —
the same on any phone.
H1Soft is an IT technology startup making apps that work the same on iPhone and Android. We make four everyday tools, three lifestyle apps with a world of their own, and four games.
Small builds, clear principles
The same on any phone
Built once, so every app looks and runs the same on iPhone and Android.
Built to be trusted
Work stays on your phone, nothing important is hidden in fine print, and verification data is deleted right away — in every app.
Small team, fast finish
From tools to brand apps, a few people iterate plan → design → ship.
Fast, simple, and on your device.
Light tools for every day — everything happens on your phone, and nothing is sent anywhere.

What is H1Soft?
H1Soft is an IT technology startup that builds mobile apps. We build each app once so it works the same on iPhone and Android, across three areas: everyday tools, lifestyle and games.
What kind of apps does H1Soft make?
Three areas: everyday tools (QR Scanner, Seukscan, Ongle, Phone Cleaner) built fast and simple, lifestyle apps (Mongle, Attachment Plush, Gyeol) built for the long run with their own brands, and four games: Sudoku Voyage, SAGAK, Nonogram Trip and Meowbro.
Where can I see Mongle and Gyeol?
Each has its own landing page — the lifestyle cards above link straight to them.
Is utility app data stored on a server?
No. Our everyday tools do all their work on your phone — scan and creation history stays on your device and is never sent anywhere.
What is Sudoku Voyage?
A sudoku game where every puzzle you solve moves you along a route around the world — 12 regions with 20 stages each, six technique-based difficulties, and a three-step Smart Hint that shows the way before the answer. No account, fully offline.
What is SAGAK?
A shikaku logic puzzle: you divide the grid into rectangles that hold exactly as many cells as their number. Every board has a single answer, so there is nothing to guess, and hints teach the next step instead of solving for you. Each finished division is printed as a stamp for your album. Available in 17 languages, including Korean, English and Japanese.
Do you support both iPhone and Android?
Yes. Every app is built once to work the same on both. Some apps launch on Android first, with the iPhone version following.
