Your new LEDs shouldn't be giving you headaches. If they are, the lights are almost certainly flickering — faster than your eyes can consciously detect, but fast enough to trigger migraines, eye strain, and fatigue. FlickerSpec turns your iPhone into a flicker meter, using the 240fps camera to measure exactly what your eyes can't. For compliance documentation — clinical engineering, facility management, EU Ecodesign certification — FlickerSpec generates PDF reports with IEEE 1789 and IEC PstLM verdicts that satisfy accreditation surveyors and lighting auditors. WHAT YOU MEASURE Quick Measurement (Free) Live 240fps capture with real-time results: • Dominant flicker frequency in Hz • Percent Flicker and Flicker Index per IEEE 1789-2015 • Signal-to-noise ratio and confidence rating • IEEE 1789-2015 Pass/Fail verdict • Live luminance waveform and FFT spectrum IEC Certified Measurement (Pro) 3-minute tripod capture for compliance documentation: • Short-Term Flicker Severity (PstLM) per IEC TR 61547-1:2015 • EU Ecodesign 2019/2020 PASS/FAIL (threshold: PstLM ≤ 1.0) • 8× oversampled LM flickermeter validated against all 5 IEC Table A.1 test vectors • Suitable for clinical engineering and lighting audit documentation Measurement Logging & PDF Reports (Pro) Every audit, documented: • Save measurements with GPS location, fixture photo, and notes • Single-measurement and session-summary PDF reports • PstLM + EU Ecodesign section included when applicable • Calibration certificate reference on every report • CSV export for spreadsheet workflows Calibration System (Free) Verify accuracy before any audit: • Built-in calibration web app generates a known-frequency reference signal • Point your iPhone at any screen showing the calibration page • Timestamped calibration certificate attached to all subsequent reports MEASUREMENT BANDWIDTH 240fps camera capture (Nyquist: 120 Hz) measures mains-driven LED flicker reliably: • 60 Hz flicker (half-wave LED drivers, US) — full accuracy • 120 Hz flicker (full-wave rectified, US) — frequency reliable; use the 3-min IEC flow for stable depth measurements • Above 120 Hz PWM and kHz drivers — outside camera bandwidth NO SUBSCRIPTIONS $49.99 one-time purchase unlocks everything: IEEE 1789 verdicts, IEC Certified Measurement, unlimited logging, PDF reports, CSV export, calibration certificates, report header customization with your company name and logo. Free tier: full live measurement display, frequency and metrics readout, up to 5 measurements per day — enough to check any room.

Valutazioni e recensioni

  • L’app non ha ricevuto un numero sufficiente di valutazioni o recensioni per poter mostrare una panoramica.

FlickerSpec is now free to download. • Refreshed icon and in-app palette designed to be comfortable for flicker-sensitive users (migraine, photophobia, light sensitivity). • Softened all verdict and warning colors to a low-saturation amber/sage/brick palette — easier on the eyes during long audits. • Pro tier dropped from $149.99 to $49.99 one-time. Quick Measurement (live IEEE 1789 check) and IEC Certified Measurement (3-minute PstLM tripod capture) continue unchanged.
