FAQ

Frequently asked questions

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) built fast and simple, lifestyle apps (Mongle, Skinping, LoLdating) built for the long run with their own brands, and games, starting with Sudoku Voyage.

Where can I see Mongle, Skinping and LoLdating?

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 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.
