Level Up Your Pitchers at Practice and in Games. Chart Pitches at Every Bullpen.
Rizzler Baseball turns every bullpen session into a development tool. Chart pitch location, track accuracy by pitch type, analyze sequences, and see exactly where your pitchers are improving, all from your phone or iPad. Bullpen charting and pitching analytics are included with the Pro and Club plans, and bullpens are charted in the iOS app.
Chart every bullpen session from your phone.
Log pitch type, location, and result in real time. After the session, see heatmaps that show exactly where your pitcher is hitting and where they're missing. Turn practice into measurable progress. Bullpen charting runs in the Rizzler iOS app and is included with the Pro and Club plans.
Track accuracy by pitch type and sequence.
How accurate is your kid's curveball? Can he hit the outside corner when you need him to? Rizzler Baseball tracks accuracy for every pitch type like fastball, changeup, curve, or whatever they throw. Track how well they execute pitch sequences too, so you know if they can set up hitters, not just throw strikes.
See development over weeks and months, not just one session.
Every bullpen gets saved. Pull up a pitcher's history and see the trends. Are they getting more accurate? Is their off-speed improving? Compare sessions side by side so you can show players (and parents) real, measurable growth.
Pitch count tracking with rest-day alerts.
Rizzler knows the rules. When you use Rizzler to count pitches in games, it tracks those pitch counts and tells you how long a pitcher needs rest before being available to pitch. Multi-game planning, so you never accidentally burn your Sunday arm on a Thursday. Protect your pitchers' futures with data, not guesswork.

Frequently asked questions
What plan includes pitching analytics?
Bullpen charting and pitching analytics (velocity trends, location patterns, session history) are included with Pro ($12.99/mo) and Club ($79/mo), and bullpens are charted in the iOS app. Per-game pitch counting, charting, and heatmaps are on every plan, including Free. Full details on the pricing page.
How does speed tracking work?
Pitch speeds are entered manually. If you have a radar gun, type the readings in as you chart and Rizzler tracks velocity trends over time. There is no direct radar-gun integration.
Which rest rules does Rizzler check?
Rizzler checks your game plans against Little League, USSSA, and Perfect Game rule sets, plus custom rules you define: pitch count limits, required rest days, catcher-to-pitcher restrictions, and minimum play. Rule compliance checking is included on every plan.
