The verdict: can you vibe code Tody?
You can build a personal cross-platform mobile clone of Tody using a modern React Native stack, though configuring real-time household sync will take deliberate debugging.
Tody is a focused productivity app whose core value is a condition-based decay algorithm paired with a clean mobile interface. A solo developer can build a personal clone using Expo and a local-first database with Supabase. The main friction points will be writing the custom cleaning dueness decay formula and handling conflict resolution when two household members check off chores simultaneously.
Estimated effort: 2-3 weeks part-time
What you can't replicate
- The exact 1M+ user community and organic brand trust
- Years of fine-tuning on the default chore catalog presets

Build guide
01Project Scaffolding & Database Schema
Initialize a new Expo project with TypeScript and configure the Supabase relational database schema.
Initialize a new Expo React Native project using file-based routing with TypeScript. Set up Supabase client integration. Create the database schema in Supabase with tables for 'rooms' (id, name, icon, home_id), 'items' (id, room_id, name, frequency_days, last_cleaned_at, cleanliness_score), 'households' (id, name), and 'household_members' (user_id, household_id, role). Ensure foreign keys and proper indexes are established. Write migration scripts and test connection locally.02Cleanliness Decay Algorithm
Implement the core condition-based dueness calculation logic.
Implement the core cleanliness decay calculation utility in TypeScript. The algorithm must calculate a 0-100% cleanliness score based on the 'last_cleaned_at' timestamp and the target 'frequency_days'. Clean green should transition through yellow and orange to dirty red as time exceeds the frequency window. Write unit tests covering edge cases like overdue chores, newly cleaned items, and custom frequency overrides.03Visual Dashboard & Room Cards
Build the grid-based mobile UI displaying color-coded room status cards.
Build the main mobile dashboard screen using React Native components. Create a responsive grid layout displaying room cards with dynamic color-coded background washes corresponding to the aggregate cleanliness score calculated in Step 2. Include visual indicators, progress meters, and smooth layout animations. Ensure safe-area padding and clean typography.04Chore Check-Off & Gamification (Dusty)
Add task completion interactions and the Dusty mascot state reaction.
Implement the item detail view and check-off interaction flow. When a user taps 'Clean', update 'last_cleaned_at' to the current timestamp and recalculate the score instantly. Implement the 'Dusty' mascot component that changes facial expressions and emotional text prompts based on the overall household cleanliness percentage (happy when clean, crying or angry when dirty). Add celebratory micro-animations on check-off.05Pomodoro Focus Timer
Integrate a built-in focus countdown timer for cleaning sessions.
Build a dedicated 'Focus Timer' screen and modal featuring a customizable Pomodoro countdown timer (e.g., 15, 25, or 45-minute blocks) with play, pause, and reset controls. Allow users to select specific pending tasks from their dueness list to target during the focus session. Play a subtle audio chime when the timer completes.06Real-Time Household Sync
Enable multi-device household syncing using Supabase Realtime.
Configure Supabase Realtime subscriptions in the Expo app state layer so that when one household member marks a chore as completed, all connected devices update their room cards and dueness scores instantly without manual refreshes. Handle offline state queuing and optimistic UI updates gracefully.

Vibe code Tody: FAQ
- Can you vibe code Tody yourself?
- Solid side project — 72/100 vibecodeable. You can build a personal cross-platform mobile clone of Tody using a modern React Native stack, though configuring real-time household sync will take deliberate debugging.
- How long does it take to vibe code Tody?
- 2-3 weeks part-time — roughly 25-35 hours of hands-on time with an AI coding agent.
- How do you build your own Tody?
- Scoped to personal use: Expo (React Native) with TypeScript and File-based routing on the front, Supabase Edge Functions / Realtime behind it, Supabase (PostgreSQL with Row Level Security) for data. Follow the 6-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Tody without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 2-3 weeks part-time. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Tody instead of paying?
- About ~$20 one-time to start and $0/mo to run, versus $9.99/yr (~$0.83/mo) for Tody. Break-even: Never (purely for learning and personal customization).
- What stack should you use to vibe code Tody?
- Expo (React Native) with TypeScript and File-based routing; Supabase Edge Functions / Realtime; Supabase (PostgreSQL with Row Level Security); plus Zustand for client state management, Lucide React Native for UI icons.
