A one-time unlock keeps scanning unlimited for your entire trip. No subscription. Everything runs on-device. WHY KIREILENS Japanese washlet-style toilets often have 8 to 15 buttons, labeled only in Japanese, mixed with pictograms that vary by manufacturer. In a hurry, the wrong button is embarrassing at best — and soaking at worst. KireiLens reads the panel, matches each label against a travel-focused dictionary, and shows you what the button actually does. WHAT IT DOES • Point, tap the shutter — instant labels on every button. • Tap for detail — one sentence explains what the button does, without jargon. • 8 languages — English, Japanese, Simplified Chinese, Traditional Chinese, Korean, Spanish, French, German. • Emergency-first — emergency call buttons are highlighted in red so you never confuse them with flush or bidet. • Fully offline — works in Airplane Mode, on cellular, on hotel Wi-Fi that blocks everything. PRIVACY BY DESIGN Every image is analyzed on your iPhone. Nothing is uploaded. No account is required. No analytics SDKs. No ads. No tracking. HOW TO USE 1. Open KireiLens 2. Point your camera at the wall panel or seat-side remote 3. Tap the shutter to capture 4. Read the labels overlaid on each button.
