The Predictable Keyboard
About this app
FlickBoard is a keyboard for Android that doesn’t try to correct or predict you. It doesn’t have an opinion on the correct spelling or tone. It certainly doesn’t use any AI. Because it trusts you to write what you meant to write.
Instead, FlickBoard uses swipes to get away with using vastly fewer (and larger!) buttons than a traditional QWERTY keyboard, helping you build muscle memory, minimize typos, and touch type faster.
Type the letters in the center of a key by tapping it. Type the keys in the corners by swiping in that direction. It’s that simple!
FlickBoard is inspired by MessagEase and Thumb-Key.

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 se.nullable.flickboard 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, 0.3.3 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall FlickBoard 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 FlickBoard, and a listing is removed when the evidence for it stops holding up.
