+
+## Purpose
+
+The goal of this app is to provide a minimalist but powerful tool for people to track life milestones using the Nostr protocol. It's completely censorship-resistant and optionally anonymous.
+
+Examples:
+
+* Days **since** quitting alcohol
+* Days **since** last porn use
+* Days **since** last cigarette
+* Days **until** a planned event like a trip, wedding, or conference
+
+The app encourages positive habit tracking and event anticipation. Counters are personal but shareable, with optional zapping support.
+
+---
+
+## User Roles
+
+### Anonymous Visitor
+
+* Can view public counters
+* Cannot create or save counters
+
+### Nostr Logged-In User
+
+* Can create counters (published to Nostr relays)
+* Can edit/delete own counters (via NIP-01 signature)
+* Can receive zaps
+
+---
+
+## User Flows
+
+### 1. Login
+
+* User connects a Nostr signer (e.g. extension or mobile app)
+* App stores the pubkey in state (no server-side session needed)
+
+### 2. Create a Counter
+
+* Click `+ Days Since` or `+ Days Until`
+* Fill form: title, type, date, visibility
+* App constructs a `kind: 30078` event
+* Signs and publishes it to relays
+
+### 3. View Dashboard
+
+* Shows counters created by the user
+* Sorted by creation or date proximity
+
+### 4. Public Viewing
+
+* Counters from all users marked `public`
+* Optional featured section
+* Zap button visible if NIP-05 or lightning address is detected
+
+### 5. Share a Counter
+
+* Permalink to `/counter/:slug`
+* Users can repost or share
+
+---
+
+## Event Fetch Logic
+
+* Use NDK to fetch kind 30078
+* Filter by:
+
+  * Author pubkey (for personal dashboard)
+  * Tag `visibility=public` for public view
+* Parse date and type for rendering
+
+---
+
+## Edge Cases & Decisions
+
+* Two counters with same `d` tag? Latest one overrides for that user
+* Private counters are not displayed publicly, even if published to relays
+* If date is in the future and type is `since`, display warning
+* Zap metadata must be fetched separately using NIP-05 or kind:0 event
+
+---
+
+## Philosophy
+
+This is a lightweight, open, and empowering way to track progress. It's built on top of Nostr to ensure:
+
+* Decentralized data storage
+* No vendor lock-in
+* Optional pseudonymity
+* Easy integration with the Lightning Network (via zaps)

+# Architecture.md
+
+## Overview
+
+"Nostr Count" is a fully client-side web app that allows users to track and share life counters using the Nostr protocol. Events are stored as `kind: 30078` and fetched using Nostr relays. It includes two counter types:
+
+* Days **since** a past date (e.g., quit smoking)
+* Days **until** a future event (e.g., vacation)
+
+The app does **not require a backend**, but can optionally use one for caching, trending counters, and zap analytics.
+
+---
+
+## Tech Stack
+
+### Frontend
+
+* **React 18 + TypeScript** – UI and component structure
+* **Tailwind CSS** – Styling
+* **NDK (Nostr Dev Kit)** – Nostr integration
+* **Day.js** – Date calculation and formatting
+* **Vite** – Build tool (or Next.js if SSR required)
+
+### Nostr Relays
+
+* Default relays (configurable via `.env` or app settings):
+
+  * `wss://relay.azzamo.net`
+  * `wss://relay.damus.io`
+  * `wss://nostr.oxtr.dev`
+* Events published and read via NDK
+
+### Optional Backend (Future Option)
+
+* Node.js/Express or FastAPI
+* Purpose:
+
+  * Cache counters per pubkey
+  * Track zap totals per counter
+  * Optional user API for bookmarks/favorites
+

+
+---
+
+## Components
+
+### `CounterCard`
+
+* Displays a single counter (days diff + title)
+* Button to share or open
+
+### `CounterFormModal`
+
+* Modal for creating/editing a counter
+* Inputs: title, date, type, visibility

+### `NDKProvider`
+
+* Provides global access to NDK instance
+* Handles login, signer, and event fetch/publish
+
+---
+
+## Future Features (Not MVP)
+
+* Comments (reply to counter event)
+* Counter streaks
+* Private reminders
+* iCal export or notification system

+
+## Purpose
+
+This guide explains how to create and publish "Days Since / Until" counter events on Nostr using NDK (Nostr Development Kit).
+
+Counters are stored as `kind: 30078` events with metadata tags for rendering.
+
+---
+
+## Prerequisites
+
+* NDK installed
+* Signer available (via NIP-07, NIP-46, or npub/nsec input)
+* Relay pool configured and connected
+
+---
+
+## Example Setup
+
+```ts
+import NDK, { NDKEvent, NDKPrivateKeySigner } from "@nostr-dev-kit/ndk";
+
+const ndk = new NDK({
+  explicitRelayUrls: [
+    "wss://relay.azzamo.net",
+    "wss://relay.damus.io"
+  ]
+});
+await ndk.connect();
+
+// Login with nsec
+const signer = new NDKPrivateKeySigner("nsec1...");
+ndk.signer = signer;
+await ndk.signer.user();
+```
+
+You can also support login via npub (read-only) or NIP-07 browser extension.
+
+---
+
+## Create Counter Function
+
+```ts
+async function publishCounter({
+  title,
+  date,
+  type = "since", // or "until"
+  visibility = "public", // or "private"
+}: {
+  title: string;
+  date: string; // format YYYY-MM-DD
+  type?: "since" | "until";
+  visibility?: "public" | "private";
+}) {
+  const event = new NDKEvent(ndk);
+  event.kind = 30078;
+  event.tags = [
+    ["type", type],
+    ["title", title],
+    ["date", date],
+    ["visibility", visibility],
+  ];
+  event.content = "";
+
+  await event.sign();
+  await event.publish();
+  return event;
+}
+```
+
+---
+
+## Public Counter Example
+
+```ts
+const ev = await publishCounter({
+  title: "Quit smoking",
+  date: "2024-12-01",
+  type: "since",
+  visibility: "public",
+});
+console.log("View at /counter/" + ev.id);
+```
+
+### Published JSON Output:
+
+```json
+{
+  "kind": 30078,
+  "content": "",
+  "tags": [
+    ["type", "since"],
+    ["title", "Quit smoking"],
+    ["date", "2024-12-01"],
+    ["visibility", "public"]
+  ],
+  "created_at": 1725000000,
+  "id": "note1...",
+  "pubkey": "npub1..."
+}
+```
+
+### Slug / Permalink
+
+Use the full event ID as the URL slug:
+
+```
+/counter/note1xyz...  ← based on event.id (NIP-19 encoded)
+```
+
+---
+
+## Private Counter Example
+
+```ts
+await publishCounter({
+  title: "Last relapse",
+  date: "2025-07-01",
+  type: "since",
+  visibility: "private",
+});
+```
+
+> Note: Private counters are still published to relays but can be filtered out in the app logic.
+
+---
+
+## Reading Events
+
+To fetch all public counters:
+
+```ts
+const events = await ndk.fetchEvents({
+  kinds: [30078]
+});
+
+const publicEvents = Array.from(events).filter(e =>
+  e.tags.find(([k, v]) => k === "visibility" && v === "public")
+);
+```
+
+To fetch your own counters:
+
+```ts
+const user = await ndk.signer?.user();
+const events = await ndk.fetchEvents({
+  kinds: [30078],
+  authors: [user?.pubkey || ""]
+});
+```
+
+---
+
+## Notes
+
+* The URL slug for counters is the **event ID** (NIP-19 encoded if needed)
+* Event `id` is used to lookup and display the counter
+* Lightning zaps should be handled via metadata (fetch kind:0 or NIP-05 info)
+* Updating a counter means publishing a new event with new content
+
+---
+
+Let me know if you want to include zaps, NIP-75 fundraising goals, or update/delete flows.
