Pitch Counting & Charting — Track Every Pitch, Protect Every Arm

Rizzler counts pitches in real time during games, calculates rest day requirements automatically based on your league's rules, alerts you before a pitcher hits their limit, and charts pitch locations for post-game heatmaps. It runs on your phone in the dugout and takes one tap per pitch. No clicker. No mental math. No forgetting the count when the third baseman's mom asks you a question.

Open the iOS app during the game and navigate to your pitcher. For each pitch, tap one button: ball or strike. That's it.

Rizzler does everything else:

Live count. The current pitch count is displayed prominently — visible at a glance from across the dugout.

Rest day projection. As pitches accumulate, Rizzler shows the rest day impact in real time. "If you pull him now: 1 rest day. If he finishes this inning (~8 more pitches): 2 rest days." You see the tradeoff before making the decision.

Limit alerts. When your pitcher approaches their league's daily maximum, Rizzler sends an alert. For an 11-12 year old in Little League, that means a warning at 75 pitches (10 before the 85-pitch limit). You'll never accidentally exceed the limit.

Catcher-to-pitcher tracking. Rizzler tracks catching innings alongside pitch counts. If your catcher has caught four or more innings, the app flags them as ineligible to pitch — preventing one of the most common rule violations in youth baseball. More about pitch count rules →

Pitch-by-pitch log. Every pitch is recorded with its count (ball/strike). After the game, you can see the full sequence — useful for identifying patterns like "he started every inning with two balls" or "he threw 90% strikes in the first three innings and 50% in the fourth."

Pitch charting takes counting one step further. Instead of just ball/strike, you tap the strike zone location where each pitch landed. After the game, Rizzler generates a heatmap showing your pitcher's tendencies.

Pitch charting is optional — you can count pitches without charting locations. But the heatmap data is valuable for practice planning and for conversations with your pitcher about where to work.

Different leagues have different rest day rules. Rizzler knows them all.

When you set your team's governing body (Little League, USSSA, Perfect Game, or custom), Rizzler loads the correct pitch count limits and rest day thresholds. After every game, the app calculates the earliest date each pitcher is eligible to pitch again.

In the game planning view, pitchers with rest day restrictions are flagged. You can't accidentally assign a pitcher who isn't eligible — the app blocks it.

In tournament planning mode, rest day calculations cascade across multiple games. Throw 55 pitches on Saturday morning? Rizzler shows the impact on Saturday afternoon, Sunday morning, and beyond. More on tournament pitching →
