Chart Every Pitch. Retire the Clipboard.
Rizzler replaces paper pitch charting sheets with one tap per pitch. Call the pitch type and location, log the result, and watch every pitcher's heatmap and accuracy analytics build themselves. Chart during games or as a standalone job for a bench coach; it doesn't have to be tied to scoring. Pitch charting is included with Coach and Club plans.
Call the pitch before it's thrown.
Select the pitch type and target location: fastball, changeup, curveball, slider; inside, outside, up, down. Rizzler logs what you called so you can compare the pitch plan to what actually happened. It's the paper pitch chart your dad kept in the stands, minus the paper and the postgame data entry.
One tap for the result of every pitch.
Ball, strike, swinging strike, foul, batted ball. Type in the speed from your radar gun if you run one. Every pitch you chart feeds the pitcher's heatmap and season analytics on both the iOS app and the web app.
Heatmaps and accuracy by pitch type.
See where each pitcher actually locates, not where you hope they do. Accuracy by pitch type, strike percentage, and location heatmaps update with every charted pitch, so you can spot the flat fastball arm-side miss before the other team's cleanup hitter does.
Pitch counts and rest-day tracking come along free.
Every charted pitch counts. Rizzler tracks pitch counts per game and flags required rest days, so charting for development also keeps you league-compliant without a separate clicker in your pocket.
“We track every pitch now. The heatmaps alone changed how we develop our pitchers.”

“One parent used to keep the pitch chart on a clipboard and we never looked at it again. Now it's in the app and we actually use it between starts.”

Frequently asked questions
Is pitch charting the same as scoring the game?
No. Pitch charting captures pitch type, location, and result; scoring captures at-bats and the box score. They work great together in Game Scoring, but a bench coach can chart pitches as their own job while someone else scores, and everything lands in the same game record.
How is this different from bullpen charting?
This page is about charting live game pitches. Rizzler also charts bullpen sessions with the same pitch-type and location detail for practice-day development; see Bullpens & Pitching Analytics. Both feed the same pitcher heatmaps and trends.
Does it work for softball?
Yes. Rizzler supports baseball and softball, and pitch charting works the same way for both: call the pitch, tap the location, log the result.
What plan includes pitch charting?
iOS pitch-by-pitch charting with pitch location comes with Coach and Club, along with heatmaps, pitching analytics, and bullpen charting. Per-game pitch counts are free on every plan. Full details on the pricing page.
