IntrinsicPower vs FlickerSpec

The IntrinsicPower App connects Intrinsic Power's charging equipment to a user friendly control system allowing charge equipment owners advanced and easy control over their networked charges and allows the public to easily find and use chargers on the network. Charger Users: Find a place to charge See charger availability and pricing before you arrive Scan and initiate charge sessions See your user history of energy used and carbon offset Equipment Owners: Make chargers Public or private Control charger access Easy to setup Load Balancing Clean monthly statements for monetized chargers

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 documentation — clinical engineering, facility management, lighting audits — FlickerSpec generates PDF reports that record the IEEE 1789 result and IEC PstLM value together with the standard, threshold, measurement uncertainty and calibration reference behind them. FlickerSpec is a screening and documentation aid, not an accredited laboratory instrument; whether a report satisfies a particular surveyor or regulator is their determination. WHAT YOU MEASURE Quick Measurement (Free, unlimited) 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 • Live luminance waveform and FFT spectrum • No daily limit — measure as many fixtures as you like IEEE 1789 Verdicts (Pro) Turn raw numbers into a documented decision: • IEEE 1789-2015 verdict against the published low-risk practice: PASS, FAIL, or Can't confirm when the capture or framing cannot support a pass • Custom pass/fail thresholds when your specification differs • The standard and threshold applied are recorded with every saved measurement 3-Minute PstLM Measurement (Pro) 3-minute tripod capture for documenting low-frequency flicker: • Short-Term Flicker Severity (PstLM) per IEC TR 61547-1:2015, for dominant frequencies up to 90 Hz • Compared against the PstLM ≤ 1.0 limit cited by EU Ecodesign 2019/2020 (PstLM only — Ecodesign also requires SVM, beyond FlickerSpec's 240fps phone-camera pipeline) • 8× oversampled LM flickermeter checked against all 5 IEC Table A.1 test vectors • Camera-based measurement aid, not an accredited instrument or certified result 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 threshold-comparison 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) is designed for 50 Hz mains regions: • 50 Hz and 100 Hz flicker (50 Hz mains) — frequency and modulation depth • 60 Hz and 120 Hz flicker (60 Hz mains, e.g. North America) — the dominant frequency may still be identifiable, but depth and the verdict that depends on it are conditional because 240 fps is an exact multiple of both. The app reports Can't confirm when it cannot sample the whole cycle. • Above 120 Hz PWM and kHz drivers — outside camera bandwidth • Modulation depth is a lower bound unless the light fills the region of interest NO SUBSCRIPTIONS $49.99 one-time purchase unlocks everything: IEEE 1789 risk indications, 3-Minute PstLM Measurement, unlimited logging, PDF reports, CSV export, the calibration certificate document, report header customization with your company name and logo. Free tier: unlimited Quick Measurements with the full live readout — frequency, percent flicker, flicker index, SNR and confidence — plus free calibration.
