Bloating, headaches, low energy, and you can't see a pattern? Was it lunch, last night's wine, a stressful day or that extra coffee? mySymptoms is a food journal and symptom tracker that looks for the patterns for you. Log what you eat and how you feel, and it shows which foods, drinks and daily factors are associated with your symptoms. Used by over 1.2 million people since 2010, and featured by Healthline in The Best Gut Health Apps. Try mySymptoms free for 7 days, then continue with a 1, 6 or 12-month subscription. Cancel anytime. HOW IT WORKS 1) Log your day: search over 1 million foods, scan a barcode or pick from your Frequents, then add your symptoms, sleep, stress and anything else you want to track 2) Keep logging for 28 days, so the analysis has enough of your data to work with 3) Open Insights to see what's associated with your symptoms, with every result explained in a plain-English sentence No calorie counting and no diet targets: just your diary and the patterns in it. "I did the one week trial and was sold. I've already recommended it to friends and family." – App Store review MORE THAN A FOOD DIARY What you eat and do: • Food and drink, including your own foods and recipes • Medication and supplements • Exercise, stress, your period and your environment How you feel: • Any symptom you choose, with intensity, duration and notes • Sleep quality, mood and energy • Bowel movements (Bristol scale) INSIGHTS FROM YOUR OWN DIARY • See which foods and factors are associated with increased or reduced symptoms • Looks at the ingredients in what you eat, not just whole meals • Every result shows a confidence level, so you can tell which patterns have plenty of data behind them and which need more logging • Look beyond symptoms: see what's associated with your sleep quality, mood, energy and bowel movements too • The Insights Timeline shows what you ate, did and felt on one interactive timeline • Trend charts and reports show how your symptoms change over time USED IN PEER-REVIEWED RESEARCH mySymptoms diary data has been used in peer-reviewed research: a 2024 study in Digestive Diseases and Sciences analyzed 9,710 anonymized diaries and found that coffee, alcohol and artificial sweeteners had time-linked associations with gut symptoms.
