## What is Churun?

Add gloss to the nails only. Even out the skin only. Blur the background only.
A photo editor for nail work, built by a working salon owner.
For salon shots and for keeping track of your own nails alike.

FEATURES
• Automatic AI separation
  A hybrid of Apple Vision and our own Core ML model separates nails, skin and background for you.
  Straight after the shot, every layer is ready to edit on its own.

• Never lose a pixel of the nail
  The gloss, texture and color of the nail are fully protected.
  Smoothing and blur are applied to skin and background only.

• Full resolution, start to finish
  Edit and export 4000×3000 images with no downscaling.
  Photos are saved back to your library at their original quality.

• An editor that keeps up with you
  Four tabs — Nails, Skin, Background and All — each with its own set of effects.
  Dial in the amount and see it update instantly.

• Fully offline, fully private
  Every photo is processed on your device. Nothing is ever uploaded to a server.

アプリを「爪の編集」により集中できるよう、画面と機能を整理しました。

・ホーム画面をシンプルにしました。「写真を選んで編集」からすぐに編集を始められます
・あまり使われていなかった機能（コラージュ・ベストショット選別・撮影プロファイル）を整理しました。プリセットやサロンロゴの透かしは、これまでどおり編集画面からご利用いただけます
・爪がうまく認識できなかったときに、意図しない加工がかかってしまう不具合を修正しました

引き続き、精度と使い心地の改善に取り組んでいます。お気づきの点があれば、ぜひフィードバックをお寄せください。

### 1.1.1 — 2026-06-23

仕上がりの質感を、より自然に調整しました。

・各エフェクトの効き具合を実機での見え方に合わせて見直しました。スライダーを動かしたときの変化がより自然になり、狙った加減に合わせやすくなりました
・特にシャドウやホワイトニングなど、一部の効果が強くかかりすぎていた点を改善しています

引き続き精度と使い心地の改善に取り組んでいます。お気づきの点があれば、ぜひフィードバックをお寄せください。
