First-Ball Leave Stats
Detailed Scoring records exact standing pins and powers these exact leave-pattern stats. Quick Scoring still records normal scores/spare percentage, and a flagged split still counts toward Split Conversion %, but Quick mode does not create an exact leave pattern.

USER GUIDE
How to Use Popz Bowling Stats
A quick guide from installation through scoring, stats, backup, and feedback.
Set Your Name & Google Sync
Open Settings and enter your bowler name. You can use Popz Bowling without an account, or choose Sign in with Google so your completed series and stats automatically follow you across your devices.
Start a Series
Tap Bowl. Enter the date, league or practice name, bowling center, number of games, oil pattern, entering average, handicap settings, and an optional series name. If you leave the average blank, the app uses the running average already stored for that same league or Practice when available. The default handicap is 90% of 220; change it if your league uses something different.
Record Ball, Lane & Line
Ball and lane tracking remain part of the Free app. Advanced Shot Tracking is off by default. To use frame-by-frame Ball + Stand + Target tracking, open Settings and enable Advanced Shot Tracking. During PRO PREVIEW it is unlocked; once enabled, change the setup whenever you move or switch balls and earlier frames stay unchanged.
Choose Quick or Detailed Scoring
Quick Scoring is the default. Just tap how many pins fell after each shot; Popz handles strikes, spares, opens, the 10th frame, scratch score, handicap, and handicap score automatically. If the first ball leaves a split, tap Mark Split before entering the second ball; you can also correct the Split flag later by editing that frame. If you want exact standing-pin/leave statistics, open Settings → Scoring Mode and choose Detailed Scoring.
Detailed Leave Tracking
When Detailed Scoring is enabled, a pin deck appears after a non-strike first ball. Tap the pins still standing and choose Save Leave & Continue. That extra step powers exact leave-pattern, single-pin, 10-pin, and per-leave conversion statistics. Quick Scoring skips the pin deck, but a Quick-mode split flagged with Mark Split still counts toward overall Split Conversion %.
Fix a Mistake
Use Undo for the most recent roll. To correct an older frame, tap that frame on the scoreboard, change the roll values, adjust the Split checkbox if needed, and save it. The score and split statistics recalculate automatically.
Move Between Games
Use New Game when the next game is ready. When the bowling session is over, tap Finish Series. The app first shows a This Series results screen for only the series you just completed; choose Continue to Overall Stats for cumulative stats, or open History.
Use Stats
The Stats screen shows average, high game, high series, strike/spare percentages, leave conversions, and performance breakdowns. Exact leave/split/conversion stats come from Detailed Scoring; Quick-mode frames still count toward normal scores and spare percentage. Filter by league/practice, bowling center, lane, ball, or oil pattern. In Settings → League Average Rule, each league can either carry its book average forward or establish a new whole-number average after a chosen number of actual games.
Review History
Tap History to see saved series and frame-by-frame game details. Expand any completed series to enter or correct its Entering Average later; handicap and league running-average stats update immediately. Without Google Sync the history stays local; when signed in, completed history syncs across your devices.
Back Up Your Data
Popz Bowling requests persistent browser storage and automatically downloads a JSON safety backup whenever you finish a series. Keep those backup files somewhere safe such as Files, iCloud Drive, Google Drive, or another backup location. You can also use Export Backup anytime and Import JSON in Settings to restore.
Use Another Device
The easiest method is Google Sync: sign in with the same Google account on each phone, tablet, or computer and your completed series and stats merge automatically. Share / Transfer Backup and Import JSON remain available as a manual recovery or transfer fallback.
Updating the App
When Popz Bowling detects a newer production version, an Update available notice appears. Stay online, fully close the app, and reopen it. The notice automatically disappears only after the running app confirms it matches the latest version. If it remains, open popzbowling.com in Chrome or Safari, refresh once, then reopen the installed app. Updates replace app files only and do not erase bowling history.
Delete a League or Category
Open Settings → Delete League / Category, select the league or category you no longer want, and confirm. Every saved series under that exact name is removed. Deletion markers are included in backups so an older device backup does not bring those deleted series back later.
Feedback
To report a problem or suggest an improvement, use Email Feedback; it sends to [email protected]. The app version and device information are included automatically.
Privacy: Popz Bowling Stats does not require an account. If you do not enable Google Sync, bowling history stays on this device. If you sign in with Google, your completed bowling history is stored in your private Popz Bowling Firebase account so it can sync across your devices; Firestore rules restrict that data to your signed-in account. Anonymous product-usage telemetry remains separate and does not include your scores or bowling history.
Settings & Backup
Account & Plan
Pro PreviewAll Pro features are unlocked during the public preview.
Scoring Mode
Quick Scoring is the default: enter only how many pins fell on each roll and keep bowling. If a first ball leaves a split, use the one-tap Mark Split button so Split Conversion % still stays accurate. Detailed Scoring adds the standing-pin deck so Popz can also track the exact leave pattern, single pins, 10-pins, and per-leave conversions.
Advanced Shot Tracking PRO PREVIEW
Off by default. Turn this on to show Ball + Stand Board + Target Board controls while bowling and record that first-ball setup frame by frame. Normal game-level Ball and Lane tracking stays available when this is off, and previously recorded setup history remains visible.

Storage protection
Checking…The app requests persistent browser storage. Finished series also download a safety backup automatically so browser-data clearing is less likely to wipe the only copy.
Google Sync PRO PREVIEW
Sign in with Google to keep completed series, stats, bowler name, and league average rules synced across your devices. You can still bowl offline; an active series stays on this device until Finish Series.
Not signed inChecking Google Sync…Protect your bowling history
Automatic backups are downloaded after Finish Series. You can also export another backup anytime and save it to Files, iCloud Drive, Google Drive, or another safe place.
Transfer to another device
Share a complete backup from this phone or tablet using Quick Share, AirDrop, Google Drive, email, Messages, or another available sharing app. Then import that JSON file on the other device.
Import a backup
Merge a Popz Bowling Stats JSON backup into this device. Existing series stay here; missing series are added, and newer copies of the same series win.
League Average Rule
Set this separately for each league. Carry Book Average keeps the entering/book average in the running calculation. Establish After X Games uses the book average until the threshold, then switches to the whole-number actual average (total pins ÷ actual games, fraction dropped).
Choose a league to set its average rule.Delete League / Category
Permanently removes every saved series recorded under the selected league or category. Practice appears here only if you have Practice series saved.
Anonymous usage statistics
Helps Popz understand whether the app is actually being used. Only app-use events such as opens, series started/completed, and feature views are sent. Bowling scores and bowling history are not sent.
