Vertigo Log helps you record vertigo and dizziness attacks from Ménière's disease, BPPV, and similar conditions right when they happen, without fumbling through forms. An attack can start suddenly, and typing is the last thing you want to do. So just tap "Attack Started." The start time and barometric pressure are saved for you. When it's over, choose the severity and the duration is filled in. You can also start from a Home Screen or Lock Screen widget, or with Siri. At your appointment, show your doctor your records as they are. Vertigo Log is for tracking only. It does not diagnose, treat, or assess the severity of any condition. Talk to a doctor about any symptoms that concern you. WHAT YOU CAN DO - One tap to start, one choice to finish Tap when an attack starts. The Home screen shows that it's ongoing and how much time has passed. When it ends, tap "Attack ended" and choose Mild, Moderate, Severe, or Very severe. The start time survives closing the app or restarting your iPhone. Fix the duration later in hours and minutes. You can also log past attacks. - Start from the Lock Screen, Home Screen, or Siri Add the Log Attack widget, or say "Log an attack in Vertigo Log." The Home Screen widget also shows your attack-free days. - Add details later Type (spinning, floating, lightheaded), duration, symptoms (nausea, tinnitus, hearing loss, headache, ear fullness), which ear, situation (on waking, standing up, going to bed, under stress, rolling over, getting up, looking up), possible triggers (poor sleep, salt, caffeine, alcohol, fatigue, menstruation, long screen time), and notes. - A daily check-in at night Log whether you had an attack, plus tinnitus, floating, and ear fullness on a four-point scale. Attack-free days count too, so the Home screen can show your attack-free days and attack days this month. An optional reminder is off by default. - Log medications in one tap Attach the medications you took and when. You add the names yourself; there is no drug database. Follow your doctor's or pharmacist's instructions for doses and timing. - Barometric pressure widget and forecast Choose a nearby city from a built-in list, including all 50 US states. Your location is never used. See current pressure and its trend on your Home Screen in hPa or inHg, with the time it was last updated. An optional purchase adds a 24-hour forecast chart and alerts before big drops or rises. The forecast is about the weather. It is not a prediction of your symptoms. - Pressure saved with each attack With a city selected, the app uses the same value as the forecast. Otherwise it uses your iPhone's sensor, on your device. - Trends See the times of day attacks happen most, plus your most-logged triggers and situations over the past 90 days. These are simple counts, not a finding about the cause. - Calendar See attacks and logged attack-free days at a glance. Compare 14 days of pressure history with your attacks and daily check-ins. - Backup Export your records and settings to a file and restore them on a new phone. - Doctor visit summary Choose a period and export attacks, frequency, average and longest attack duration, pressure, symptoms and affected ear, situations, possible triggers, and medications as a PDF to share with your doctor. YOUR PRIVACY Your attack records stay on this device. No account or login is needed. If you use the pressure forecast, the app connects to get the forecast for the city you chose; your records are never sent. Weather data is provided by Apple Weather. ONE-TIME UNLOCK Attack logging and durations, widgets, attack-free days, Siri, daily check-ins, medication logging, recent history, the current month's calendar, and current pressure are included. A one-time in-app purchase, not a subscription, unlocks the full calendar, forecast and alerts, the forecast chart widget, trends, and the doctor visit summary PDF. No ads.
