Build the tracker you keep searching the app store for.

Build a personal habit tracker.
Use the codata MCP server for the backend. Create tables for habits (name, goal per week, color) and check-ins (habit, date). Use Codata IO sign-in so each person only sees their own habits.
Screens: today's list with one-tap check-ins; a weekly grid view; a streak counter and a chart of completion rate per habit over the last 8 weeks.
Make it work well on my phone and feel calm and minimal.

DESIGN (follow exactly)
Style: calm and minimal, rounded 16px corners, lots of white space; each habit gets its own soft color.
Layout: mobile first, with a bottom tab bar: Today, Week, Stats.
Today: big tappable rows (56px) with a color dot, the habit name and a round check button that fills with a small animation.
Week: a 7-column grid of circles per habit; filled means done.
Stats: the streak as a big number at the top ("12-day streak"), then a small line chart per habit.
Empty state: "Add your first habit" with 3 one-tap suggestions (Drink water, Walk 10 minutes, Read).
Colors: off-white background, white cards with soft 1px borders, near-black text, and ONE accent color: [your brand color, e.g. #2F5BFF] for buttons and highlights only.
Type: one clean sans-serif (e.g. Geist or Plus Jakarta Sans), 16px body text, generous line spacing.
Use Tailwind with shadcn/ui components. Add empty, loading and error states, and make every tap target at least 44px.
Build the main screen first with these exact specs and show it to me. After my OK, connect it to Codata IO.

Add notes to each check-in and a search across all my notes.

Set up a Codata IO scheduled task that emails me every Sunday evening with my best and worst habit this week, in one sentence each.

Check that no user can see another user's habits and that no keys are in the code. Then deploy on Codata IO hosting, give me the live URL, and tell me how to add it to my phone's home screen.
