Hydration: not enough data yet
Not medical advice. Compared on this phone.
Foods eaten this many hours before a check-in are compared with how you felt.
Nutrient and ingredient patterns across dishes (for example onion in burritos and pizza). Approximate values from your own logs.
Ranked by how often a less-comfortable check-in follows that food in your logs.
Protein, carbohydrates, calories, fat, fiber, and weight. Water stays on Today. Tracking only — not diet advice. Stored on this phone and included in your export. Never sent to the crowd.
Sample crowd rankings. Nothing leaves this phone until you opt in.
You vs. Crowd runs on-device. Opt-in sharing is separate. Local DP · vocabulary foods only · rotating IDs · k≥50 · no notes or exact times.
Your logs stay on this phone. BariLogic lives at https://barilogic.pages.dev. Clearing site data or switching devices starts fresh. Moving to the new address is done on this phone, and nothing is sent to a server.
Made-up logs from 500 fictional people over 6 months (about 180 days). Crowd charts use aggregates computed in memory — not every raw row on this phone. The device keeps one person’s full log. Not medical advice. Demo logs are never shared or included in export.
Removing demo data restores your gut profile and the sample crowd. Your own meals and check-ins stay.
Optional. Helps compare with people who have a similar digestive setup. Stored on your device by default — never shared unless you separately opt in below.
A personal label only. Sleeve, Bypass, DS, Loop, Other, or None.
BariLogic is a personal logging tool, not medical advice. Talk to your care team about health questions.
Height is saved as a history, so older BMI numbers stay tied to the height you had then. Weight, height, BMI, and nutrition goals never go to the crowd. They are included when you export your own data.
App works fully offline with the built-in food list. Typed search sends only the food name through this app’s server — never your meals, weight, goals, or profile. A barcode lookup sends only the barcode digits. Meal photos stay on this phone.
U.S. Department of Agriculture, Agricultural Research Service. FoodData Central, 2019. Contains information from Open Food Facts, available under the Open Database License. The server reads FDC_API_KEY if you set one. A key typed below is kept on this phone and is not sent.
A key saved here stays on this phone and is not sent. The server uses its own FDC_API_KEY. Open Food Facts needs no key.
You vs. the Crowd comparisons are computed on-device from downloaded aggregates — your meal and check-in history does not need to leave the device for comparisons. Nutrition lookups send only the food search term when you tap Look up — never automatic, and never your personal logs.
Optional reminders while BariLogic is open. We only ask after you tap this button. A closed app will not be woken.
