Pitch count and score tracker for baseball, softball, and kickball officials.
About this app
Umpire Assistant helps baseball, softball, and kickball officials track pitch counts, runs, and game state during a game.
Features:
• Pitch count tracking — balls, strikes, fouls, and outs with automatic walk, strikeout, and inning advancement • Score tracking for home and away teams with batting team indicator • Inning tracker with top and bottom half display • Configurable game clock with expiry alert • Undo and redo for accidental taps • Volume button assignments for heads-up pitch counting without looking at the screen • Multiple saved configurations for different rule sets (rec league, tournament, etc.) • Named teams with color coding, saved per configuration • Flexible foul rules: fouls as strikes, strike cap, foul outs, track-only, or off • Large button layout option for single-hand use • Share final score via any app on your device
No ads. No tracking. No internet connection required.

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.adiamas.umpireassistant 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 Umpire Assistant, 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 Umpire Assistant, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets Umpire Assistant do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
No earlier build is on record — this is the first release we have listed.
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
