StrikeSheet

The app does this arithmetic. You tap what fell.

01 The score did not go up after my strike

That is correct behaviour, and it is the single most common question about any bowling scorer.

A strike is worth ten pins plus whatever you knock down on your next two balls. Until those two balls have been thrown, the frame's total cannot be known, so StrikeSheet leaves it blank — exactly as a paper score card does. A spare works the same way but waits on one ball instead of two.

Bowl on. The moment the bonus balls land, the earlier frames fill in.

02 How the tenth frame works

The tenth frame is the one that trips people up, so here is the whole rule:

• Strike on the first ball → you get two more balls, on a fresh rack.
• Spare on the first two → you get one more ball, on a fresh rack.
• Neither → the frame ends after two balls.

StrikeSheet only ever offers you the balls you have actually earned, and it re-racks between them when the rules say it should. If the keypad stops after two balls, the tenth was open — that is the rule, not a bug.

03 I tapped the wrong number

Tap Undo in the top right. It removes the very last ball thrown in the session, whoever threw it, and hands the lane back to that bowler. Tap it repeatedly to walk further back.

There is no separate edit mode — undo far enough and re-enter. It is quicker than it sounds, and it means the score can never drift out of step with the balls that produced it.

04 Bowling with other people

Add up to eight bowlers when you start a game. This is free and always will be.

StrikeSheet works out whose turn it is from the score card itself: the bowler furthest behind is up, and the lane passes over automatically the moment a frame closes. You never mark a turn as finished.

To score out of order — someone stepped away, someone bowled twice — tap that bowler's chip at the top and enter their ball. The app returns to automatic order as soon as their frame closes.

With more than one game each, everybody finishes game one before anyone starts game two, the way a league night runs.

05 What is free and what is Pro

Scoring is not the paid part. It never becomes the paid part.

StrikeSheet Pro is a one-time purchase. Not a subscription, and there are no adverts in either tier.

06 Pin-by-pin scoring

In Pro, switch the keypad to Pin by pin and tap the pins you knocked down instead of typing a count. The rack on screen shows what is still standing, and StrikeSheet labels a leave SPLIT the moment one appears.

It counts a leave as a split when the head pin is down and the standing pins form more than one separated cluster — so 7–10, 3–10 and 5–7 are splits, and 4–5 is not, because those two pins are neighbours.

A game only counts toward your split rate and leave analysis if every ball in it was entered this way. Half a game on the quick keypad would make those percentages misleading, so StrikeSheet leaves such games out rather than quietly averaging them in.

07 Leagues, series and handicap

A league in StrikeSheet holds two numbers: a basis score and a percentage. Your handicap is that percentage of the gap between the basis and your average, rounded down and never below zero.

A 90% league off 220 with a 180 average gives (220 − 180) × 0.90 = 36 pins. Both numbers are yours to set — leagues differ, and StrikeSheet does not assume yours.

Your season average is taken from every completed game in that league, so it moves as the season does. Picking a league when you start a game sets it to three games each, which is what most league weeks are; change it if yours is not.

08 New phone, or the same games on my iPad

Your games sync through your own iCloud account, using the same Apple Account on both devices. There is no StrikeSheet account to make and no password to remember.

If a new device looks empty, check that iCloud Drive is on and that iOS has finished the first sync — it can take a minute on a cold start. Games created while offline upload when you are next on a network.

To get Pro back on a new device, open Settings → Restore purchase. It is tied to your Apple Account, so it costs nothing a second time.

09 Deleting things

Swipe a session left in the Games list to delete it and every game in it.

Settings → Erase all games removes everything — games, sessions and leagues — from the device and from your iCloud copy. It cannot be undone, so StrikeSheet asks first.

Deleting the app removes its local data. The iCloud copy goes when you delete it in iOS Settings → your name → iCloud → Manage Account Storage.
