开发者在美国 App Store 的完整简介（英文原文）。
KeyLevel 88 Regulation Map is a local-first workbench for independent piano technicians and small regulation shops. Map the complete physical A0–C8 keyboard, preserve stable key identity, and record technician-entered regulation measurements without pretending to measure or diagnose the piano automatically. Capture reference and current values, mark unknown or unverified points explicitly, review keyboard-wide completeness, compare visits, and preserve provenance. Export technician handoffs in JSON, CSV, or PDF, and use backup, restore, recovery copies, and deletion controls without an account or cloud sync. The free tier includes a useful end-to-end regulation-map workflow. Independent Pro adds multi-piano workspaces, repeated-visit comparison, longitudinal history, and reusable technician baselines. Monthly and yearly plans renew automatically; Lifetime is a one-time purchase. Restore Purchases is available in the Pro screen. KeyLevel 88 does not tune pitch, listen to audio, automatically measure physical geometry, certify work, or replace technician judgment. No account, ads, analytics, tracking, or external payment is used. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
