Aurora Notes keeps every note encrypted on your device and syncs the moment you find signal, so drafts written offline are never lost or silently overwritten.

About this app
Aurora Notes is a note-taking app built around a simple premise: your notes should be readable when the network is not. Everything you write is encrypted on the device with a key derived from your passphrase, and edits are held in a local queue that replays in order the next time you connect. If two devices change the same note while offline, Aurora Notes keeps both versions side by side rather than picking a winner for you — a small decision that matters if you take notes on a phone in the field and clean them up on a tablet later.
The app suits people who write a lot in awkward conditions: researchers, journalists, site engineers, and anyone whose commute passes through dead zones. It is less suited to teams who want live collaborative editing, since the sync model is deliberately queue-based rather than real-time. The tablet layout adds a two-pane editor with keyboard shortcuts, and Android's biometric prompt can gate the vault without the passphrase being stored anywhere.
Aurora Labs publishes to Google Play first and mirrors the same artifact on its own servers for users who cannot reach Play. APKBrowse lists both, plus a community mirror page that we link to for reference but never proxy. The publisher-hosted APK is the only download APKBrowse serves directly, and only because Aurora Labs authorized it in writing; that download resolves through a short-lived signed URL and supports resumable byte ranges for slow connections.
Before installing, check two things. First, the signing fingerprint below — Aurora Labs has used the same key since its first release, so a build that does not match it did not come from the studio, regardless of what the file is called. Second, the minimum SDK: version 2.3.1 requires Android 8.0 or newer, and installing it on an older device will fail with a parsing error rather than a helpful message. If you are already running an Aurora Notes build from a different signer, Android will refuse the update and you will need to uninstall first, which erases the local vault unless you export it.

Aurora Notes questions, answered
Is it safe to install Aurora Notes from an APK instead of the Play Store?
It is safe when the APK comes from Aurora Labs itself, which is the case for the publisher-hosted download listed here. The risk with APK installs is not the file format but the source, so the practical rule is to install only builds whose signing fingerprint matches the one Aurora Labs publishes.
How do I verify the download is genuine?
Compare the SHA-256 hash of the file you downloaded against the hash listed for that version on this page, which Aurora Labs also publishes in its release log. If you already have the app installed, you can check the signing fingerprint with any APK inspection tool; it should be identical across every version the studio has ever shipped.
Will Aurora Notes work on my Android version?
Version 2.3.1 requires Android 8.0 (API 26) or newer and ships arm64-v8a and armeabi-v7a binaries, which covers essentially every phone and tablet sold in the last several years. Devices on Android 7.x can still run 2.2.0, which lowered the requirement to API 24, though it does not receive security fixes.
What permissions does Aurora Notes request?
It requests internet access for sync, notification permission for reminders, and biometric access for unlocking the vault. It does not ask for contacts, location, or storage access, and the sync queue only transmits encrypted blobs.
How do I roll back to an earlier version?
Android will not downgrade an installed app in place, so you have to uninstall 2.3.1 before installing 2.2.0, and uninstalling clears the encrypted vault. Export your notes first from Settings, and be aware that the 2.2.0 build no longer receives fixes.
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 com.auroralabs.notes 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, 2.2.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Aurora Notes 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 Aurora Notes, and a listing is removed when the evidence for it stops holding up.
