Grimo is the assistant that finally understands the way you actually think β talk to it like a person, and it handles the rest. No forms. No dropdowns. No hunting through five different menus to add one appointment. Just say what's on your mind, and Grimo turns it into the right task, event, or note β exactly where it belongs. WHAT GRIMO DOES β’ Chat naturally β type or talk, and Grimo figures out whether you're adding a task, booking time on your calendar, or jotting something down to remember later. β’ Voice mode β hold to talk and have a real back-and-forth conversation, hands-free. Perfect for when you're cooking, driving, or just don't feel like typing. β’ Tasks β organized by category and priority, with a swipe to complete or delete. β’ Calendar β a clean month view where every category gets its own color, with distinct shades so overlapping trips, meetings, and appointments never blur together. β’ Notes β quick capture for anything that doesn't need a date attached β wifi passwords, ideas, things people tell you. Everything lives in one place, connected by one assistant that understands context across all of it. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: BigOit at none against Grimo AI's 1. BigOit also leads on update cadence (every 2 days vs every 2 weeks). Grimo AI's advantage is iOS requirement (16.4 vs 26.0). On price, ads and device support there is nothing between them.
