BellySignal is a poop tracker and bowel diary for recording your daily digestive patterns. Log stool form with the Bristol stool chart, urine color, water intake, and food and habits in one place. Start without an account. KEEP A BOWEL MOVEMENT DIARY Choose a Bristol stool type from 1 to 7, record color, and note blood or mucus you notice. Add observations such as belly pain, bloating, urgency, or straining to keep a useful record over time. TRACK WATER, FOOD AND HABITS Log water toward your daily goal and record urine color. Add coffee, alcohol, dairy, spicy food, stress or poor sleep to look back at what happened around changes in your digestion. A pattern does not prove that a food caused a symptom. REVIEW TRENDS AND EXPORT A PDF See your entries together in Trends. Export a PDF summary of the last 90 days from Settings and choose whether to share it at a medical appointment. You can also export a backup file and restore it later. START WITHOUT SIGNING IN Your diary is stored locally by default. An account is optional. If you sign in, you can turn on automatic backup, which saves a copy of your diary to our cloud storage so you can restore it on a new phone. You choose where exported files go and whether to enable health-platform integration. Some health values, including stool type, symptoms and manually entered weight, are sent to PostHog, which is on by default. The Usage analytics switch controls PostHog only. Firebase Analytics receives usage events without those health values and stays active even when the switch is off. Deleting local entries does not automatically delete analytics data that has already been sent. You can delete your diary entries in Settings. BellySignal is a self-recording tool, not a medical device. It does not diagnose IBS, food intolerance or other conditions, determine the cause of symptoms, or provide treatment. Discuss concerns with a qualified healthcare professional. Privacy Policy: https://bellysignal.com/en/legal/privacy/ Terms of Service: https://bellysignal.com/en/legal/terms/

About

Bladder Diary

Features
Read full description

Bladder Diary turns each bathroom trip into one tap, and turns weeks of taps into a chart your doctor can actually read. HOW IT WORKS 1. Tap once when you go. That's a complete entry. 2. Measuring? Add the amount with the number pad, or stack the presets (200 + 50 = 250). 3. Log what you drink on the same timeline, so you can see what came before each trip. 4. Open the chart tab, or export a one-page summary before your appointment. WHAT MAKES IT DIFFERENT - Logging is never interrupted. One tap saves; no full-screen ad stands between you and the record. - Every entry can be edited or deleted. Wrong time, wrong amount, wrong day - fix it in two taps. - A real by-the-hour chart. Not just daily totals. Night hours are shaded so you can see when they cluster. - Type exact numbers. A large keypad, not a scroll wheel. - Your own presets. Change the mL buttons to match your measuring cup. WHAT YOU CAN RECORD - Time of each void, and the volume if you measure it - Urgency, leaks, and pad changes - Fluid intake by type: water, coffee, tea, soda, alcohol, soup WHAT YOU GET BACK - Voids per day, split into daytime and night - Average and largest void - Total intake and how it lines up with your voids - A by-the-hour chart for a day, a week, or a month - A one-page image you can send to your doctor, plus CSV for your own records FOR YOUR APPOINTMENT Urologists routinely ask for a few days of bladder records before a visit. The export screen builds that page for you: the numbers, the hourly chart, and the date range, sized to fit one screenshot. PRIVACY Your records stay on your device. Nothing is uploaded. Files you export go only to the app you choose to share with. IMPORTANT This app is a logging tool. It does not provide medical diagnosis or treatment, and it does not calculate clinical scores. If you have symptoms, talk to a healthcare professional. Open it, tap once, done.
