StopTime

StopTime measures machine stopping time from high-frame-rate iPhone recordings and calculates safety distances for supported EN ISO 13855 cases. Analysis runs on your device, without an electrical connection to the machine. ITALIAN AND ENGLISH Italian is selected when the iPhone's primary language is Italian; English is used for all other languages. Choose Automatic, Italiano or English in setup or About > Settings > Language. Interface, learning materials, animated diagrams, calculators and generated report text support both languages. LEARN AND ARCHIVE: FREE Articles, animated diagrams, examples, glossary and quizzes. View saved measurements and reports even after a subscription expires. BASE: MEASURE AND CALCULATE Record at up to 240 fps, subject to the camera formats available on your iPhone. Review trigger and stopping frames, repetitions and the uncertainty budget. Ten calculators include formulas, steps, warnings and PDF calculation sheets. Full normative tables are not included: cases requiring unavailable tabulated data do not produce a distance or numerical comparison. Stopping-time records can still be retained. In Italy: EUR 3.99/month or EUR 39.90/year. Eligible Apple Accounts receive a 14-day free trial, once per subscription group. Session report printing and export are purchased separately. SINGLE REPORT EUR 19.00 in Italy for one measurement session, including all repetitions. Print and export its PDF, package and JSON/CSV data, with later reprints and revisions included, even without a subscription. One-time payment; no renewal. Retain the session in Archive and a device backup. UNLIMITED EUR 23.90/month or EUR 229.99/year in Italy. Includes Base plus printing and report exports for any session, without a measurement-count limit. Sessions exported during the subscription remain unlocked on the device after expiry. To transfer these local entitlements, retain the Archive and an encrypted device backup. No free trial for Unlimited. APPLE PURCHASES Apple shows the applicable local price, duration and any trial before confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the current period or trial ends. Manage or cancel through your Apple Account settings. Restore and manage purchases from Archive > Subscription. Restoring purchases does not recreate deleted files. Completed Single Report restoration on iOS 17 depends on retained local entitlements. Terms: https://raveng.it/en/stoptime/terms/ Apple EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://raveng.it/en/stoptime/privacy/ REPORTS AND LIMITATIONS Reports are UNVALIDATED TECHNICAL DRAFTS requiring professional verification. They include frames, plots, uncertainty, calculations and SHA-256 digests. They do not by themselves establish machine safety or conformity. StopTime is not a calibrated instrument and does not replace risk assessment or professional judgement. No qualified signature or iOS PDF/A conformity is promised. DATA AND TIMESTAMPS No StopTime account. Videos and measurements are processed locally. RFC 3161 requests send SHA-256 digests and technical data to external providers, not complete videos or reports; providers also receive the IP address. Connectivity and provider availability are required. Status and limitations appear in the app; no qualified timestamp is promised. Apple handles purchases and renewals. PATENT-PENDING METHOD Italian patent application no. 102026000027877, filed with UIBM on 25 September 2026, concerns contactless stopping-time measurement from an audio-video stream. It does not cover the calculators or learning materials.
