LudyMeter measures sound levels with professional accuracy — and does two things no other app can: track your noise exposure under EU workplace safety rules and detect musical notes from frequency peaks. No subscription. No ads. No data leaves your device. --- WHAT YOU GET FOR FREE --- The free tier is genuinely useful, not a teaser. You get a real-time A-weighted decibel meter with min, max, and average tracking. See how loud your environment is compared to everyday sounds ("As loud as a vacuum cleaner" or "Hearing damage risk after 2 hours"). Save your last 7 days of measurements and share beautiful sound level cards with friends. Works entirely offline. --- PRO ($14.99 one-time) --- Unlock the full frequency analyzer: real-time FFT spectrum, 1/1 and 1/3 octave band display, and musical note detection that translates raw frequencies into note names like A4, E3, or Bb2 — with cent deviation. Compare before and after with A/B measurement snapshots. View spectrograms and get EQ recommendations for your room. Export unlimited measurement history to CSV. Supports A, C, and Z frequency weighting plus Fast, Slow, and Impulse time constants. Perfect for musicians, sound engineers, and audio enthusiasts who want a professional spectrum analyzer without a professional price tag. --- SAFETY ($49.99 one-time) --- The first and only iOS app with EU Directive 2003/10/EC noise exposure tracking. Calculate LEX,8h (daily noise exposure normalized to 8 hours), track LCpeak, and monitor your dose percentage in real time. A three-zone warning system turns green, amber, or red at the EU action values of 80, 85, and 87 dB(A). Get haptic alerts when you cross a threshold. Run full-shift background monitoring without keeping the screen on. Generate PDF screening reports with timestamps, location, and exposure status for workplace documentation. Also includes NIOSH and OSHA dosimeter modes for US workplace standards. Note: LudyMeter is a screening and awareness tool. It does not replace certified Class 1 or Class 2 sound level meters required for legally binding workplace noise assessments. --- WHY LUDYMETER --- PRIVACY FIRST Zero data collection. Zero analytics.
