Extreme 100x hybrid zoom camera with local image processing.
About this app
Open 100x is an Android camera app built to give more phones access to extreme 100x zoom-style shooting, even when the stock camera app does not expose that kind of range.
It combines native camera zoom with digital crop to reach up to 100x, and adds controls designed for long-range mobile photography. The app includes stability feedback, histogram tools, grid modes, zoom presets, flashlight support, crop nudging, and local post-processing for extreme zoom captures.
Open 100x runs fully on-device. It uses traditional, non-AI image processing only, with no cloud processing and no external APIs.
Current beta notes:
* Android app package: com.example.zoomhundred * Up to 100x zoom through native camera zoom plus digital crop * Local denoising, smoothing, sharpening, contrast/detail recovery, and crop upscaling * Pro-style overlays and anti-shake feedback for high-zoom shooting * Device behavior may vary because camera hardware and third-party lens access differ across Android devices

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)

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 com.example.zoomhundred 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
No earlier build is on record for Open 100x, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
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 Open 100x, and a listing is removed when the evidence for it stops holding up.
