Keystone - Habits & AI Planner

Tired of juggling five different apps just to stay organized? Keystone brings your habits, goals, shopping lists, journal, and a private AI assistant together in one place — so you can stop switching apps and start making real progress. ★ THE PROBLEM WE SOLVE Most people use a separate habit tracker, to-do app, journal, shopping list, and planner. Nothing talks to each other. You lose context, motivation drops, and staying consistent feels impossible. Keystone fixes that. ★ BUILD HABITS THAT ACTUALLY STICK Track habits with streaks, priorities, and flexible schedules. See exactly how consistent you've been with trend charts, calendar heatmaps, and momentum tracking. When you skip a day, you'll know — and when you're on a roll, you'll feel it. ★ PLAN & EXECUTE COMPLEX GOALS Break big goals into multi-step missions. Execute them step by step, build streaks, and earn points as you make progress. Whether it's "Learn Spanish" or "Renovate the kitchen," Keystone keeps you moving forward. ★ PRIVATE AI ASSISTANT — BUILT IN Ask the AI to create tasks, plan missions, build a weekly meal plan, or generate a packing list for your trip. It runs on Cloudflare's privacy-first infrastructure — your conversations are never used to train AI models and stay in your account only. No extra subscription, no data harvesting. ★ SMART SHOPPING LISTS Track groceries with repurchase reminders that learn when you need to restock. Organize by categories, set quantities, and share lists with family — everyone stays on the same page. ★ JOURNAL & MOOD TRACKING Write daily journal entries guided by thoughtful AI prompts. Track your mood over time and spot patterns you wouldn't notice otherwise. ★ EVERYTHING IN ONE VIEW Your Today tab shows exactly what needs your attention — habits to complete, mission steps due, recurring tasks, and upcoming events. No guessing, no digging through separate apps. ★ END-TO-END ENCRYPTED Your data is encrypted on your device before it ever leaves. We literally cannot read your entries, notes, or habits — only your devices can decrypt them. ★ SYNC ACROSS DEVICES Start on your phone, continue on the web. Everything stays in sync automatically. ★ SHARED LISTS & COLLABORATION Share grocery lists, chore lists, or project plans with family and friends — all encrypted. ★ REWARD YOURSELF Create custom rewards and "buy" them with points you earn from completing tasks. It's a simple trick that keeps you coming back. ★ COMPLETELY FREE Every core feature works at no cost. No paywalls, no trial periods. Premium is optional and adds quality-of-life extras like momentum boost and ad removal. Stop app-hopping. Build your foundation with Keystone.
