People are tired of their medical routines being tracked by big corporations.<br> ​Carebell is my answer to that. Key technical choices:<br> ​Offline-First: No remote database. Your pills, your schedule, your history—it stays on your hardware.<br> ​No Sign-up Friction: I removed the "Create Account" wall. You're in the app in 1 second.<br> ​Minimalist Stack: Focused on a clean UI (inspired by Revolut/Apple) to make a "boring" task like taking meds feel premium.<br> ​🚀 Launching as is a challenge,<br> ​Local-Only Trust: Selling the "Offline" feature as a premium security benefit.<br> ​💬 I need your "Dev" perspective:<br> ​As developers, do you think the "Zero Cloud" model is a feature people will actually pay for in 2026, or is the convenience of syncing still too dominant?<br> ​Check the project here: <a href="https://play.google.com/store/apps/details?id=com.vnytalab.carebell" rel="noopener noreferrer">https://play.google.com/store/apps/details?id=com.vnytalab.carebell</a><br> ​I'd love to hear your thoughts on the UI and the "No-Account" UX.<br> ​Keep building!</p> showdev privacy flutter android
