An allergy tracker app for symptoms, possible triggers, and doctor reports.

Record how your allergies felt, what you were around, and when symptoms changed. Allergy Tracker keeps a private history on your iPhone so you can look back before an appointment without guessing from memory.

Download on the App Store Free to log. Reports and export are a one-time purchase, not a subscription.

No account, no ads, no tracking. Your check-ins stay on your iPhone and, if you're signed in to iCloud, in your own private iCloud account.

How it works

Three steps, a few seconds each

Log how you feel

Open the app and tap a severity: None, Mild, Moderate, Bad, or Severe. That's a complete, saved entry.

Add detail if you want

Mark symptoms, note that you took medication, pick what you were around, or add a short note. Everything past the first tap is optional.

Look back on your history

See your check-ins as a list or a month calendar, fix or delete anything, and create a doctor report when you need one.

Possible triggers

Log what you were around

Any check-in can include what you were around. Pick from the list, or type your own, like the name of a new detergent.

Allergy Tracker keeps these next to how you felt, so you can look back on them later or show them to your doctor. It records possible triggers. It doesn't decide what caused your symptoms.

On the list

  • Dust or cleaning
  • Bedding
  • Pets
  • Mold or damp
  • Laundry products
  • Fragrance or scented products
  • Smoke
  • Being outdoors
  • Mowing or yard work
  • New product
  • Anything you add yourself

Calendar

See your month at a glance

Switch History to Calendar and each day is shaded by its worst check-in, so a run of bad days stands out. Tap a day to see what you logged.

A few weeks in, you can see whether this stretch has been worse than last month or only felt that way.

  • Each day shaded by its highest severity
  • Tap a day to see its check-ins
  • Move back through earlier months
  • Switch to the list to see every check-in

Doctor report

Bring a clearer history to your next appointment

From History or Settings, create a PDF of your logged history for the last 30 days, the last 90 days, or all time. Share it from your iPhone, print it, or save it to Files.

The report counts what you logged. It doesn't interpret your symptoms and it isn't a medical assessment, so what it means is up to you and your doctor.

The doctor report comes with Lifetime, an optional one-time purchase (US$19.99 in the US; the App Store shows your local price). No subscription.

In the report

  • Check-ins, days logged, bad or severe days, and symptom-free days
  • Days by severity

  • Exposures you recorded on those days, as plain counts
  • Your most recorded symptoms
  • Every check-in with its date, time, severity, exposures, and notes

Privacy

Built to stay private

Your allergy check-ins live on your iPhone. If you're signed in to iCloud, they also sync to your own private iCloud account so your history follows you to your other Apple devices.

Your iPhone creates reports and CSV files, and they go only where you send them.

  • No sign-up, no login, no user account
  • No ads, no analytics, and no tracking
  • No location permission
  • No pollen, weather, or air-quality service
  • The developer never receives your check-ins or reports

Also in the app

Small things that keep the log useful

Check in as often as you like

Log once a day, or every time things change. Each check-in keeps its own time.

Fill in a missed day

Add a past check-in with its own date and time. Edit or delete any entry later.

Recent summaries

Allergy days, bad or severe days, and your most common symptom over the last 7 days. The 30-day summary comes with Lifetime.

CSV export

Export every check-in, exposures included, as a CSV file you can open in a spreadsheet. Comes with Lifetime.

Optional daily reminder

One reminder a day, at a time you pick. Your iPhone schedules it, with no server involved.

Four languages

English, Polish (polski), Dutch (Nederlands), and Brazilian Portuguese (português do Brasil), following your iPhone's language settings.

Allergy Tracker helps you keep a record of your own allergy days. It doesn't diagnose, treat, predict, or tell you what causes your allergies, and it doesn't recommend medical care. The doctor report is a record of what you logged, not a medical assessment.
