Track hearing, symptoms and treatments over time. Generate structured reports for your ENT.
Free to download · iOS
Connect Apple Health or run a quick in-app hearing test. EbbChart builds a longitudinal picture of your thresholds over time — not just today's reading, but the pattern across weeks and months.
Record vertigo, tinnitus, aural fullness, medications, flights and other events alongside your hearing data. See what correlates.
Produce a multi-page PDF formatted for clinical review. Your hearing trends, medication timeline, episode events and trajectory classification — ready to bring to your ENT appointment.
EbbChart was built by David McAvinue after developing cochlear hydrops and discovering that the hearing changes occurring between appointments were largely invisible to the healthcare system.
The condition fluctuates. Thresholds shift over days and weeks. By the time a clinic appointment arrives, the episode — the deterioration, the partial recovery, the response to treatment — has already passed. The audiogram at the appointment captures a single moment. The story in between is lost. EbbChart exists to preserve that story.
Import your audiogram history automatically — from Mimi, Apple Hearing Test, or any app that writes to Apple Health.
EbbChart charts your thresholds longitudinally. See trends across 7 days, 1 month, 3 months, 6 months or your full history.
Generate a structured clinical report — multi-page PDF with hearing trends, medication timeline and trajectory summary. Formatted for review, not a screenshot.
EbbChart is designed for people living with conditions where hearing fluctuates over time:
EbbChart is not designed for stable hearing loss or general hearing aid users. The longitudinal tracking model is most valuable when hearing changes over time.
EbbChart is a personal tracking tool for longitudinal hearing and symptom data. It is not a diagnostic device, does not replace calibrated clinical audiometry, and does not provide treatment guidance. Home audiogram measurements vary by device, headphones, environment and user behaviour (±5 dB). EbbChart reports should be treated as supplementary patient-generated context for clinical review.
