Ad-free viewer for WiFi otoscope cameras.
About this app
Otoscope is a clean, ad-free replacement for the proprietary apps shipped with cheap Wi-Fi otoscope cameras.
The stock companion apps — "AIR-Look" (Wudaopu / Xylla hardware) and "EarVision" (Shenzhen Jiding / JEGOAT hardware) — bundle a dozen ad and analytics SDKs (AdMob, AppLovin, IronSource, MBridge, Vungle, Pangle, Mintegral, etc.) and a sprinkling of in-app tracking. Otoscope reimplements just the connection and viewer functionality, with nothing else.
Features:
* Discover the camera over Bluetooth Low Energy. * 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 UDP protocol — 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.
Supported hardware families (the right protocol is selected automatically from the BLE advertisement):
* Wudaopu / Xylla — Wi-Fi SSID `Enjoy-XXXXXX` or `JesHome-XXXX`, open AP. * Shenzhen Jiding / JEGOAT — Wi-Fi SSID `softish-XXXXXX`, WPA2.
Otoscope is GPL-3.0-or-later and contains no third-party trackers, ad SDKs, or proprietary native libraries.

- Keeps the screen awake while you're streaming, so it doesn't turn off mid-exam. Scoped to the streaming view; the device goes back to its normal sleep timeout as soon as you disconnect.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be dev.rubec.otoscope is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.4.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Otoscope first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Otoscope, and a listing is removed when the evidence for it stops holding up.
