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.
