Frequently Asked Questions

No. PitchGuessr makes no connection to the game whatsoever. All data entry is manual — you tap the zone as you watch each pitch happen on your TV or monitor. The app never touches game servers, game accounts, or any MLB or Sony systems.

An iPhone or iPad running iOS 17 or later. That's it. No account, no login, no internet connection required during use.

Tap the + button on the home screen. Enter your opponent's name and set their pitcher handedness (Left or Right). That's the whole setup — you're ready to start tracking immediately.

The heatmap starts building on pitch 1. By 5–10 pitches you'll see tendencies forming. By 15–20 pitches at a specific count, the Standard Model gives you real signal. The Confidence badge tells you exactly how much to trust the current prediction — Very Low, Low, Medium, High, or Very High — so you always know the strength of the data behind it.

Standard Model filters predictions by the exact current count (e.g., 1-2) AND the handedness matchup (e.g., RHH vs RHP). Most specific — best when you've accumulated count-specific data.

Matchup Model ignores the count entirely and shows overall tendencies for the handedness matchup (e.g., all Left vs Right pitches, regardless of count). Broader sample — best at the start of a game before count-specific data builds up.

Both models are free. Tap the model name in the status bar to switch instantly while you're tracking.

Each zone's color follows its percentage on one scale: white → light blue → blue → yellow → orange → red.

White (light gray in the outer ball zones): under 5% — no real signal yet, or a zone they rarely use.

Light blue to blue: about 5–35%. With 25 zones to spread across, this is where most of the action lives — the deepest blue is usually the zone to sit on.

Blue shading into yellow: about 35–55% — a strong lean.

Yellow to orange, then red: 55% and up (red from about 75%) — they go there most of the time.

The more pitches you log, the more accurate the color distribution becomes.

The Confidence badge shows you how much data is behind the current prediction. There are five levels, and the pitch counts behind them depend on the model. Standard (pitches at this exact count and matchup): Very Low (1–2), Low (3–5), Medium (6–10), High (11–20), Very High (21+). Matchup (pitches in this handedness matchup, any count): Very Low (1–5), Low (6–12), Medium (13–25), High (26–50), Very High (51+). With no pitches logged yet it shows No Data. Use it to gauge how aggressively to trust the heatmap.

Unlimited at-bat tracking, full heatmap predictions, both prediction models (Standard + Matchup), the Confidence indicator, In-Zone / Out-Zone percentage tracking, pitch sequence overlay, and all three Pitch Recall Modes. Saved opponents and opponent management are Pro. The free tier is ad-supported with banner and interstitial ads.

In v1.2 we removed the 9-batter per game cap — everyone gets unlimited tracking now. To sustain that, the free tier is ad-supported. If ads bother you, Lite removes them for just $2.99/year.

Lite ($2.99/year) is the same as Free but with zero ads. All core features — heatmap, both models, unlimited tracking, confidence indicator — are included. No interstitial ads, no banner ads, no interruptions.

Pro ($9.99/year) includes everything in Lite plus advanced analytics:

Zone Splits — vertical (UP/MID/LOW) and horizontal (IN/CTR/AWY) strike zone breakdowns.

Strike Rate Panel — 4x3 grid showing strike tendency for every count, color-coded by confidence.

Auto Insights (new in v1.3) — Predictability Score, a 0–100 read on how readable a pitcher's locations are, and Situational Tendencies, which show whether a pitcher attacks the zone or chases you out of it by count, plus first-pitch and two-strike tendencies.

Recency Window (new in v1.3) — base predictions on only the last 10 or 25 pitches in the matchup to spot a pitcher adjusting mid-game.

Raw mode — exact unsmoothed percentages for advanced users.

Collapsible stat panels, opponent name/notes editing, and iCloud sync across devices.

By default, PitchGuessr uses Bayesian smoothing to prevent extreme predictions from small samples — one pitch to a zone does not immediately show 100% for that zone. Raw mode (Pro only) removes this smoothing and shows exact percentages. Best for Pro users with large sample sizes who want unfiltered data.

No. Every pitch you log is saved to your opponent's profile permanently. Data accumulates across every session against the same opponent, making predictions more accurate over time.

No. There is no account system in PitchGuessr. You can start using the app immediately without creating any kind of login.

Your pitch data is not. It is stored on your device using Apple's SwiftData framework, and it only leaves the device through optional iCloud sync (Pro), which uses your own personal iCloud account — PitchGuessr has no server of its own. The free tier is different in one way: its ads are served by Google AdMob, which collects device and ad data and tracks only if you allow it. Lite and Pro have no ads. See the Privacy Policy for details.

iCloud sync (Pro feature) uses Apple's standard CloudKit integration to sync your opponent data across your iPhone and iPad using your personal iCloud account. RetroGhostLabs never sees or touches this data. Sync is optional and can be disabled in Settings.

Use Skip At-Bat to skip the current at-bat without logging anything. This keeps your dataset clean — no bad data, no guesses. You can also use Unknown Location to log the pitch result (ball, strike, etc.) without guessing the zone if you couldn't track where it landed.

Tap the undo button (↶) to remove the last pitch logged. In full-screen mode, undo is also available in the status sheet.

Long-press the Ball or Strike display to manually adjust the count. This corrects off-by-one errors without affecting your pitch history.

It means there aren't enough pitches logged for the current matchup or count situation. The app will automatically fall back to a broader filter (e.g., any count instead of the specific count) if it finds enough data there. Keep logging pitches — predictions build quickly.

Local pitch data is stored on-device and does not survive a reinstall unless you have iCloud sync enabled (Pro). With iCloud sync, your opponents, sessions, and pitches are backed up to your Apple iCloud account and will restore automatically after reinstalling. To restore your subscription after reinstall, go to Settings → Restore Purchases.
