For Serious Bowlers · Founder Round Open

YOUR PAP ISN'T A NUMBER.
IT'S A HISTORY.

Every PAP measurement, every drilling, every surface change — date-stamped, with per-ball overrides, across years and re-drills. Built for bowlers whose arsenal has a longer history than their last scoresheet.

PAP + drilling history

What makes us different

THREE THINGS
NOBODY ELSE TRACKS.

We don't list every feature we have. We list the three a serious bowler can't get anywhere else.

PAP History

MULTIPLE PAPS PER BOWLER.

Per-ball overrides.

Your PAP migrates as your release matures, after insert changes, after a coach tweaks your timing. We time-stamp every measurement and let you override it per-ball — so the Phaze you drilled three layouts ago still carries its own PAP record.

In product:Bowler-level + per-ball · date stamped · history visualization

Drilling Lifecycle

MULTIPLE DRILLINGS PER BALL.

Plugged + redrilled stays.

Bowlers redrill all the time — new layout, plugged thumb, hand surgery, switched 1-handed to 2-handed. Other apps overwrite. We keep the whole sequence per ball so you can compare 'how did this Phaze IV bowl on its first layout vs its fourth.'

In product:Sequential drill log · 2LS notation · driller notes · layout photos

Pattern Physics

FORWARD-SIM, NOT HOROSCOPES.

Real ball motion math.

We forward-simulate every ball in your bag against the oil grid using your PAP, rev rate, ball speed, axis tilt, axis rotation, plus the ball’s coverstock, RG, differential, and surface grit. Strike probability, breakpoint, entry angle — all derived, not asserted.

In product:0–100 grading · per-ball strategy panel · pattern playbook

One data model · Zero silos

ENTER IT ONCE.
IT SHOWS UP EVERYWHERE.

Other bowling apps silo your arsenal, your games, and your tournaments into separate worlds. We tied them together — so the same layout you drilled, the same tournament you logged, the same surface change you recorded all cascade through the rest of the app automatically.

You drill a ball.

New drilling

Phaze IV · 4th drilling · pin-to-PAP 4½″ · VAL 45°

  • Per-ball strategy

    Re-scores this ball against every pattern in your library.

  • Physics simulation

    Layout multipliers feed the forward-trajectory engine.

  • Arsenal score

    Coverage + gap analysis recompute.

  • Drilling timeline

    New entry on the ball's lifecycle log.

The pin-to-PAP, VAL, and dual angle you enter once feeds the trajectory engine for every pattern — no re-entry, no copy-pasting layout math.

You log a tournament.

New tournament entry

One series entry updates ball wear, your lifetime average, pattern history, spare percentages, and your trophy room. Automatically. Every game makes the next one smarter.

Every PAP measurement, every surface change, every league night, every tournament finish — all linked. The app gets smarter the more you use it because nothing you enter ever lives alone.

Pattern Intelligence

What to throw, where to stand, why it works

Import any pattern from Kegel / PBA / USBC. We model it in 3D, score every ball in your arsenal against it, and hand you a targeting line.

  • 3D oil volume render

    Visualize the pattern as actual oil — high-density red zones, friction zones, the breakpoint geometry.

  • Arsenal trajectories

    Each ball in your bag rendered as its predicted line through the pattern, color-coded by grade.

  • Match scores per ball

    Every ball ranked 0-100 against this pattern. Top pick highlighted — pick the right one in seconds.

Optimal target line

Stand-here, swing-here, hook-this-many-boards. Generated from your ball specs + pattern friction model.

Per-ball strategy

Every ball in your arsenal ranked for this pattern. Top pick gets a Forward-sim adjustment note.

Multi-game tournament plan

Six-game block? We hand you a game-by-game ball + target shift schedule for pattern transition.

Your pattern history

Avg / high / low / games on every pattern you've played. Add ball reviews and session notes.

From upload to playbook

Every pattern flows through five views.

1. Import

Drop a PDF from Kegel / PBA / USBC — we parse the spec sheet automatically.

Arsenal Analytics

Your bag, X-rayed

One arsenal score, six health metrics, and the math behind why you should — or shouldn't — drill that next ball.

    Single letter grade rolled up from 6 sub-metrics: coverage breadth, depth, variety, layout coverage, redundancy, gap coverage.

  • "What's actually working"

    Composite 0-10 rating per ball pulled from your real game results, not just the manufacturer's brochure.

  • Oil condition coverage

    Every ball plotted on the Dry → Heavy spectrum. Empty zones = your blind spots when conditions change.

FAQ

QUESTIONS WE HEAR.
AND WHAT WE ACTUALLY ANSWER.

What does "Founder" status actually mean?
Beta accounts are flagged as Founders. If we ever introduce paid plans (we haven't decided), every Founder keeps their account at no cost — current features and future ones. We won't put up a retroactive paywall on people who signed up early. It's the simplest way we know to thank early users.
How accurate is the physics simulation?
It's a model, not a measurement. We forward-simulate trajectory using your PAP, rev rate, ball speed, axis tilt, axis rotation, plus the coverstock material, RG, differential, and surface grit. It's the same parameter set Mo Pinel's MoRich layout system uses. Your mileage will vary with actual lane conditions — the engine gives you a starting point, not a guarantee.
Why do I need PAP history? My PAP doesn't change.
Your PAP absolutely shifts as your release matures, as you change inserts, or after a coach makes a tweak. Most bowlers re-measure once a year and write the old number down somewhere. We track every measurement against date and the ball it was taken on — so you can see your axis migrate over time and correlate it with score changes.
Multiple drillings per ball — why does that matter?
Bowlers re-drill all the time. New layout, plugged thumb, hand surgery, switched from 1-handed to 2-handed. Other apps blow away the old layout when you enter a new one. We keep the whole drilling history per ball — so when you want to compare 'how did the Phaze IV bowl on its first layout vs this one,' you can.
Do I need to be a serious bowler to use this?
No. If you bowl one league a week with three balls in your bag, the app is useful. If you bowl four leagues plus regional tournaments with 15 balls, the app gets MORE useful — that's where the physics engine, PAP history, and pattern playbook earn their keep.
Can I import games I bowled before I joined?
Yes. Two import paths: paste a LeagueSecretary CSV export (any standard format works), or take a photo of a paper scoresheet and let our Claude Vision integration parse the scores.
Does it work on my phone?
Yes. The web app is mobile-first and we have iOS + Android wrappers via Capacitor in beta. Live scoring at the lane was specifically designed for one-handed thumb use between throws.
Will my arsenal data be public?
Only if you explicitly opt in. The public bowler card (/b/[your-slug]) is off by default and shows only the curated fields — career stats, achievement count, top balls. Notes, scores, and PAP measurements stay private.
Is this affiliated with USBC, Kegel, Storm, etc.?
No. The BallRoom is independent. We use Kegel pattern PDFs (which they publish openly), reference USBC stats, and catalog balls from every manufacturer — but we're not partnered with any of them.
