Independent iOS studio
Sinancode makes simple iOS apps that do one job well. No accounts, no ads, no tracking — what you create stays on your iPhone.
Dual camera video recorder for iPhone
Twinly records with two iPhone cameras at once — the scene and your reaction in one take. Picture in Picture, Split, or Separate files. No account, no ads, no tracking.
Offline Japanese phrasebook with audio
Learn the Japanese you actually need in Japan — trains, hotels, restaurants, and more. Natural audio, word-by-word kana highlighting, and 100% offline. No account.
We build apps we’d want to use ourselves. That means they work without knowing who you are.
Open the app and start. We never ask for your email, phone number, or a sign-in.
Our apps contain no advertising or analytics SDKs, and we never build a profile of you.
Recordings, progress, and settings are stored on your device. We don’t collect them.
Every app has a public privacy policy and a help page with answers to common questions.
