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.

Verdict
The clearest difference is in-app purchases: うんころぐ at none against Poolendar's 6. うんころぐ also leads on update cadence (every 3 days vs every 2 months) and iOS requirement (18.0 vs 26.0). Poolendar's advantage is ads (none vs shown). On price and device support there is nothing between them.
