Hacki for Hacker News is an open-source (GPL-3.0-only) Android app by Jiaqi Feng. The APK we host is 31 MB, it needs Android 7.1 or newer, and it declares 11 permissions.

The file on this page is Hacki for Hacker News 3.8.2, 31.49 MB, and it installs on Android 7.1 and newer.

We compared the signing certificate of this build with the certificate recorded the first time com.jiaqifeng.hacki entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the app does.

The manifest inside the APK declares 11 permissions, including access to the camera. Android asks you to approve those the first time the app needs them.

Its licence is GPL-3.0-only. We took this build from F-Droid, and the source for this exact version is linked below.

F-Droid, who build and sign this package, flag it: it relies on a network service that is not open source. We pass that on as they recorded it — we have not tested the app ourselves.

We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
