Poolendar vs Circa

Living with IBS, Crohn's, colitis, or food sensitivities? Poolendar is the only tracker that logs both bowel movements AND gas to give you the complete picture of your gut health. YOUR PRIVACY IS SACRED No account. No sign-up. No analytics. Your health data belongs to you and no one else. Poolendar is designed with privacy as the absolute priority. There are no external servers storing your information. Everything is saved on your device and, if you enable iCloud, synced in an encrypted way through Apple CloudKit, the most secure infrastructure on the market. Not even we can access your data. VISUAL CALENDAR See at a glance how your gut health evolves day by day. The color-coded Bristol Scale shows you patterns you were missing before. 10-SECOND LOGGING Bristol type, stress level, and consumption chips (gluten, lactose, FODMAPs, alcohol, coffee and more) without typing anything. You can even log gas, something other apps completely ignore. AI THAT FINDS PATTERNS The AI analysis runs directly on your device. It correlates what you eat with how you feel and helps you identify potential triggers. All without sending a single byte to external servers. BREAK THE TABOO Join support groups or create your own. Sharing your progress with people who understand what you're going through makes all the difference. Digestive disorders affect millions of people, but nobody talks about them. REPORTS FOR YOUR DOCTOR Export clear, professional PDFs so your gastroenterologist sees exactly what you've experienced between appointments. Objective data that makes diagnosis and follow-up easier. DESIGNED FOR THOSE WHO NEED IT - Irritable Bowel Syndrome (IBS-C, IBS-D, IBS-M) - Inflammatory Bowel Disease (IBD) - Crohn's disease & ulcerative colitis - SIBO & bacterial overgrowth - Celiac disease & food intolerances - Any functional GI disorder FREE FOREVER Event logging is completely free, with no limits, forever. Advanced features like AI analysis, report export, and social features cost less than a coffee per month. Understanding your gut shouldn't be this hard.

Circa is an iPhone app that logs your supplements, caffeine, and nicotine in two taps and pairs them with your Google Fitbit Air data to turn the two into trend insights, audited correlations, and a live forecast for tonight's sleep. Everything is computed on your iPhone. No Circa account is needed. Circa is free and shows advertising, which is loaded over the network. PRECISE INPUTS Log anything in two taps: exact dose, exact unit, exact time. Your stack is a shortcut, never a constraint — type any amount, switch units freely (mg, g, µg, IU, pouch, ml, drops). One-tap logging from the Lock Screen widget, or just tell Siri "Log an espresso in Circa." STIMULANT PHARMACOKINETICS Live caffeine and nicotine decay curves against your bedtime, with the 50 mg caffeine threshold drawn where it matters. See what this afternoon's espresso still costs you at 23:00. AUDITED INSIGHTS Every effect ships with its receipts: n, 95% confidence interval, p-value, correlation — and the actual nights behind it as a scatter plot. Insights that fail their interval for 14 days are retired automatically. Honest null results included. TONIGHT, FORECAST A transparent driver model predicts tonight's sleep score and deep-sleep minutes from what you actually did today. Every driver shows its signed contribution. It recomputes on every log — watch the number move. A 104-SUPPLEMENT LIBRARY Goal-ranked, evidence-graded, interaction-flagged. Pick your goals and the library re-ranks itself around you. YOUR DATA STAYS YOURS Health data is read from the Google Health API and processed entirely on-device. Disconnecting revokes access and erases everything. Export anytime as CSV and JSON. Explore the full app in demo mode before connecting anything. Circa is a personal tracking tool, not a medical device. It does not diagnose, treat, or prevent any condition. Requires a Google Fitbit Air and a Google account for live data; manual logging and demo mode work without one. Recommendations for our other apps load online. Their views and taps are counted as daily totals, without personal profiles or user/device identifiers. See our privacy policy.
