Gout Diary: Uric Acid Tracker
100-Day Challenge & Purine Log
Free · Designed for iPad. Not verified for macOS.
New: one-tap purine lookup for foods, automatic mg/dL and umol/L detection, daily reminders. The 100-Day Challenge helps you bring uric acid down and keep it there.
High uric acid, or gout flares that keep coming back? The first 100 days are the hardest to stick with. Gout Diary turns uric acid management into a habit with the 100-Day Challenge.
One minute a day. Log uric acid, medication, water, urine color, food, exercise, sleep and flares — and the app builds your gout flare risk index, uric acid trend and a 100-day report you can hand straight to your doctor.
WHAT YOU GET
- 100-Day Challenge: a Day X/100 streak that keeps you going
- Purine food lookup: purine content from published sources, with a daily reference so you can check before you eat
- One-tap logging: uric acid, medication, water, 8-level urine color, high-purine meals, alcohol, exercise, sleep, weight
- Flare log with a 7-day look-back: find the triggers that are actually yours
- Trend charts and a 100-day report: see how close you are to target
- Dissolution-phase estimate and an early-phase flare warning, so you notice if levels are dropping too fast
- Uric acid spike self-check that explains why each factor matters and how much
- Automatic units: switch between umol/L and mg/dL in one tap
- A community for people tracking the same thing, with links to the medical sources behind every figure
WHO IT IS FOR
- You were told your uric acid is high but have never had a flare
- You are on urate-lowering therapy and want to see the trend clearly
- Your flares keep returning and you want to find the trigger
- You want to bring a complete record to your next appointment
IMPORTANT
This app is for logging and lifestyle review. It does not provide medical diagnosis, treatment plans, drug dosing advice, or any promise of results. The 100-Day Challenge, dissolution phase and risk index are self-observation tools only. Always talk to your doctor before starting, stopping or changing any medication, and for acute flares. Your data stays on your device by default. No account, works offline.
