Otoscope

Ad-free viewer for WiFi otoscope cameras.
New in version 0.11.0
Mirror, auto-rotate and manual rotation settings are now remembered across sessions and app launches.
Otoscope is a clean, ad-free replacement for the proprietary apps shipped with cheap Wi-Fi otoscope cameras.

The stock companion apps generally bundle lots of ad and analytics SDKs (AdMob, AppLovin, IronSource, MBridge, Vungle, Pangle, Mintegral, etc.) and in-app tracking.
Otoscope reimplements essential connection and viewer functionalities, with nothing else.

Features:

• Discover the camera over Bluetooth Low Energy or Wi-Fi.
• Join the camera's Wi-Fi access point in a one-process scope, so the rest of your traffic isn't affected.
• Live video stream, decoded in-app over the camera's protocol (UDP or RTSP). Pure Kotlin, no FFmpeg, no native blobs.
• Auto-rotation driven by the camera's on-board accelerometer / gyro.
• Horizontal-mirror toggle for self-examination.
• Circular mask matching the otoscope lens.
• Photo and video capture with a built-in gallery to review, share and delete them.
• Optional caption burnt into the corner of each capture to tell what's being recorded.

Supported hardware families:

• Xylla — SSID `Enjoy-XXXXXX` or `JesHome-XXXX`.
• iTiMO — SSID `iTiMO-XXXXXX` or `jetion_XXXX`.
• JEGOAT — SSID `softish-XXXXXX`.
• EarFairy — SSID `Cooleer_XXXXXX`.
• Soulear (i4season) — SSID `Soulear-XXXXX`.
• Y38 — SSID `AIR-ES-XXXXXX`.

Otoscope is GPL-3.0-or-later and contains no third-party trackers, ad SDKs, or proprietary native libraries.

  • New in version 0.9.0
    Adds a fullscreen view and an auto-rotate toggle. When auto-rotate is off, a rotate button next to the fullscreen one turns the image 90° at a time. Ring-light, mirror and auto-rotate now fold away under an "Options" row to keep the camera image as large as possible.
