The year-over-year pattern you were missing. 1-tap daily log: sneezing, itchy eyes, medicines. Know which days are worst and exactly why. Show your doctor the real data.
Some days your hay fever is unbearable. Others, you're fine. You have no idea what's different — and no record to look back on.
90% of hay fever sufferers say it hurts their work performance. 20-30% drop in productivity. Missed days. Early exits. All because you can't figure out what's making today worse than yesterday.
Pollen Log fixes that. Track your symptoms and medicine every day, and let the data show you what's actually working.
【What You Finally Figure Out】
• Which antihistamine actually helps you — not in theory, but in your data
• Which days are your worst, and what's different about them
• Whether this season is worse than last year — with actual numbers to compare
• What to tell your doctor instead of "it varies depending on the day"
【Everything You Need to Track】
- Symptom Log — Rate eye itch, runny nose, sneezing, and headache every day
- Medicine Record — Log what you took, when, and whether it helped
- Trend Charts — 7-day and 30-day history to see patterns forming
- Year-over-Year — Compare this season to previous years (Premium)
- Allergen Settings — Cedar, cypress, grass, ragweed, mold, and more
"I've tried three different antihistamines and still don't know which one works." — Pollen Log shows you symptom severity before and after each medicine. After a week of logging, the answer becomes obvious. You'll know which antihistamine is actually worth taking.
"Last year my allergist asked how my symptoms were — I had no idea what to say." — After a season of logging, you walk in with data: peak symptom days, which medicines helped, and how this year compares to last. That's the kind of record that changes the conversation.
"I forget to log — and then forget that I forgot." — Set a daily reminder at whatever time actually works for you. Tap once and you're done.
"Is this useful even if I'm just doing standard antihistamine treatment?" — Yes. You'll know if the standard treatment is actually working for your specific trigger, and which days you might need a doctor's appointment instead of just another Clarityn.
People say things like: "I finally know which 2 weeks of April are my worst. I take extra antihistamines before it hits now instead of during." "Year-over-year comparison showed me my symptoms are getting worse — not just my imagination." "I brought the chart to my allergist and they said it was the most useful thing a patient had ever shown them."
"Do I need to pay?" — Basic tracking is free: daily logs, medicine records, and a 7-day chart. Premium adds 30-day history, year-over-year comparison, and removes ads. Price shown before you subscribe.
