Scoreplane: Model Eval
Threshold & Calibration Lab
$1.99 · Designed for iPad. Not verified for macOS.
Evaluate labeled scores without a notebook: threshold metrics, cost-sensitive operating points, ROC, precision-recall, calibration, Brier score, and group slices.
Scoreplane is a private model-evaluation laboratory for data scientists, ML engineers, risk teams, students, researchers, and technical reviewers who need to inspect labeled scores away from a notebook or dashboard.
Import truth, score, optional record ID, subgroup, and sample weight from CSV. Move the operating threshold and see the confusion matrix, precision, recall, specificity, F1, MCC, accuracy, balanced accuracy, Brier score, and entered decision cost update together. Inspect ROC, precision-recall, and calibration views plus the same-threshold subgroup screen.

- 340 original offline model-evaluation plates
- No account, ads, analytics, tracking, IAP, or subscription
Scoreplane evaluates imported labels and scores under recorded assumptions; it does not certify fairness, safety, legality, causality, or production fitness. Review sampling, label quality, shift, subgroup context, uncertainty, operating costs, and deployment controls with accountable domain experts.
