What coaches are saying
Best app award
Best app for baseball lineups hands down. Also is great for team coordination, stats summaries. Love the app and online version.
Incredibly Valuable Tool
Who’s on Second might be the most comprehensive tool for youth baseball coaches. The depth of the rule sets and configurations saves so much time throughout the season.
Perfect for Little League
Great app and also responsive developer who has added a bunch of features for my team that have been a huge help. It’s been eye opening for the parents to see the data.
Best app for coaches!
This app has been a huge time-saver for me as a baseball coach. Before using it, I was trying to manage rosters, batting orders, defensive rotations, innings by hand.
Responsive Developer!
I’ve been using this on my phone and it has changed how I manage the dugout. … Not having to manage the pitch count by hand is huge.
Wish I’d had this tool sooner!
This app makes tracking my players easy! I don’t coach to crunch numbers, and now I don’t have to!
Everything you need at the field
Built for one-handed use in the dugout: fast, focused, and synced with your account.
Drag-and-drop lineups
Build your batting order and defensive rotations right on the diamond. Auto-generate a rule-compliant lineup in two taps, then tweak it with a drag.
Your league’s rules, built in
Minimum play, bench limits, mandatory infield innings. Toggle on the rules your league enforces and the builder flags violations in real time.
Pitch counts on your phone
Log pitches from the dugout and rest days calculate themselves. See who’s eligible, who’s resting, and who’s near their limit, even across teams.
Season-long fairness
Every inning and position is tracked so you can keep playing time balanced. Now you have the data to show any parent who asks.
Roster in your pocket
Jersey numbers, positions, handedness, and notes for every player, ready when you need them, synced with the web app you already use.
Import your schedule
Share your GameChanger schedule straight into the app and your season is ready to go. No re-typing game dates by hand.
