RateProof Capacity Study
Run at Rate Capacity Verdicts
$9.99 · Designed for iPad. Not verified for macOS.
Time cycles on the floor, get a pass or fail verdict against required capacity, and hand your customer a clean PDF or Excel report before you leave the plant.
RateProof turns a capacity verification study (a run at rate) into a single tool you carry in your pocket.
Built by a supplier quality engineer for the production floor: time real cycles with a full screen stopwatch, enter the line configuration, and watch every operation's demonstrated capacity stand against its required rate. The constraint operation is flagged automatically. When the run starts, tally good parts, scrap, and downtime hour by hour and see the projected verdict move in real time.
RateProof computes what a customer capacity form computes, so the study you run at the line matches the arithmetic your customer checks in the office.
WHAT IT DOES
- Cycle timing built for the floor: a giant lap button, works one handed, keeps the screen awake, and every lap is saved the instant you tap
- The full capacity model: parallel machines, multi cavity tooling, planned downtime, changeover time, and scrap all accounted for
- Downstream scrap propagation: every operation carries its own requirement, raised by the scrap of the operations after it, the way a customer form derives it
- Two utilization measures per operation: part capability and machine utilization, with the higher one governing and labeled
- Five risk bands at the standard 85, 90, and 100 percent thresholds, including the medium risk band customer forms distinguish
- Constraint selection with integrity: hard stops and unreadable figures outrank a manual pin, so a pin cannot hide a failing operation
- Planned versus observed reconciliation: cycle time, scrap, and downtime deltas after the run, so you see where the observation disagrees with the plan
- Live production run tally: hourly good, scrap, and downtime with a running projection
- Professional reports: paginated PDF and a fully formatted Excel workbook with real numeric cells your team can compute on
- Audit trail: every kept cycle is timestamped in the report, and discarded cycles stay visible, struck through
- Honest by construction: requirements round up, capacities round down, so the app never overstates what your line can do
- Your data stays yours: studies live on your device and files leave it only when you share them. Anonymous usage and crash reports help improve the app and can be switched off in About
WHO IT IS FOR
Supplier quality engineers, quality managers, manufacturing and process engineers, and anyone who has ever run a capacity study from a laptop balanced on a shipping crate.
