PokéTrack

A community-activity monitor for Pokémon GO. It fetches upcoming and live events, stores them locally, and shows them through two interfaces that share one design system — a CustomTkinter desktop app and a Flask web app, both in a consistent Midnight Blue dark theme.

Features

Data source	Robust parser over the ScrapedDuck JSON feed (a structured Leek Duck mirror), plus a best-effort official-blog HTML source behind the same interface.
Hybrid GUI	Desktop (CustomTkinter) + Web (Flask + Tailwind), both Midnight Blue dark mode driven by one shared palette.
i18n	English (default), Traditional Chinese, Simplified Chinese, Japanese, Korean — every string lives in languages.json.
Region filtering	Pick the regions you care about; Global events always show. Rules live in editable data/regions_map.json.
Search & filters	Live search + event-type filter + favorites in both UIs, on top of the region filter.
Rich cards & detail view	Thumbnails, synthesised descriptions, live countdowns, a live/upcoming/total stats bar, and a click-through event detail view (desktop modal / web page).
Favorites	Star event types; filter to favorites and optionally notify only for favorites.
Calendar export	Per-event or filtered .ics export, plus a subscribable web feed at /calendar.ics.
Notifications	Desktop + in-app alerts, webhooks (Discord/Slack/custom, optionally HMAC-signed), and Telegram — when new events appear in your regions.
Config import/export	Back up or move your settings from either UI.
Async + responsive	async/await (httpx) fetches off the GUI thread, with a skeleton loading screen.
Persistence	SQLite (indexed) caches events for offline viewing; old events auto-pruned.
Background updates	APScheduler on a configurable interval; the web view auto-detects new events.
Distribution	CI (pytest matrix), a Dockerfile for the web app, and a one-file Windows .exe built on release.
Graceful errors	Network/format failures never crash the UI — cached data stays visible with a localized message.
Tested	Deterministic, offline pytest suite (27 tests) covering core, service, web, calendar, favorites, HMAC, and the scheduler.

The fetching/parsing logic is fully separated from presentation: both front-ends call PokeTrackService only, and neither imports the parser or database directly.

Setup

pip install -r requirements.txt

Python 3.10+ recommended (tested on 3.13 and 3.14). Pillow (thumbnails) and plyer (desktop notifications) are used with graceful fallback — if either is missing the app still runs, just without that one feature.

Multiple Python installs? Make sure you install into the same interpreter you run with. A virtual environment avoids the mix-up entirely:

python -m venv .venv && .venv\Scripts\activate   # Windows
pip install -r requirements.txt

Run

Desktop app

python main.py

Web app

python run_web.py
# then open http://127.0.0.1:5000/

The desktop app's “Open Web View” button launches the web server for you and opens your browser.

Test

python -m pytest -q

The suite is fully offline (a fake source + temp DB) and won't touch your real config.json or data/. It also runs in CI on every push (Python 3.11–3.13).

Build & deploy

Docker (web app)

docker build -t poketrack .
docker run -p 5000:5000 poketrack      # http://localhost:5000/

Standalone Windows executable

pip install pyinstaller
pyinstaller --noconfirm PokeTrack.spec  # -> dist/PokeTrack.exe

On GitHub, publishing a Release triggers .github/workflows/release.yml, which builds PokeTrack.exe and attaches it to that release automatically.

Configuration — config.json

{
  "language": "en",                  // "en" | "zh-Hant" | "zh-Hans"
  "regions": ["Global"],             // see region list below
  "source": "leekduck",              // "leekduck" (default) | "blog"
  "refresh_interval_minutes": 60,    // APScheduler interval
  "notifications": true,             // desktop/in-app alerts for new events
  "webhook_url": "",                 // POST new-event alerts here (Discord/Slack/custom)
  "prune_after_days": 45,            // drop events that ended over N days ago
  "database_path": "data/poketrack.db",
  "web": { "host": "127.0.0.1", "port": 5000, "debug": false }
}

Webhooks

Set webhook_url (in config.json or the desktop Settings tab) to receive a POST whenever new events appear in your selected regions. The payload is shaped automatically for the destination:

URL contains	Format sent
discord.com/api/webhooks/…	Discord { content, embeds[] }
hooks.slack.com/…	Slack { text }
anything else	Generic { content, text, title, events[] }

The Settings tab has a Send test button to verify your URL.

Everything here is also editable in the app's Settings tab.

config.json is git-ignored (it can hold a private webhook URL). A config.example.json is provided for reference; the app auto-creates config.json from defaults on first run.

---

Internationalisation — languages.json

All UI text is loaded from languages.json, grouped by language then by section:

{ "en": { "events": { "view_details": "View Details" } } }

Code looks strings up by dotted key with graceful fallback (current language → English → the key itself):

service.t("events.view_details")
service.t("events.last_updated", time="…")   # supports {placeholders}

To add a language: copy the "en" block to a new top-level key (e.g. "ja"), translate the values, and add its display name under every languages block. No code changes needed.

---

Regions

Global, North America, South America, Europe, Asia, Oceania, Africa.

Leek Duck data isn't region-tagged, so PokéTrack infers a region from the event name using a keyword map (core/regions.py) — Safari Zones / GO Tour stops map to their city/continent; everything else stays Global and shows for everyone. Selecting a region (e.g. Asia) shows Global + Asia. Extend the keyword map freely as new regional events appear.

---

Design system — Midnight Blue

Deep blues, charcoal grays, and slate accents, defined once in poketrack/gui/theme.py. The desktop UI reads the hex values directly; the web layer injects the same values into its Tailwind config and CSS variables (web/templates/base.html), so the two interfaces stay identical.

Token	Hex	Use
bg	#0B1120	App background
surface	#111827	Cards / panels
surface_alt	#1E293B	Elevated surfaces
border	#334155	Slate borders
primary	#3B82F6	Primary actions
accent	#38BDF8	Highlights
text / text_muted	#E2E8F0 / #94A3B8	Text
success / warning / danger	#34D399 / #FBBF24 / #F87171	LIVE / SOON / errors

Notes & troubleshooting

• First launch shows an empty list for a second while the initial fetch runs in the background; it fills in automatically.
• Offline? Cached events from the last successful fetch remain visible and a localized "showing cached data" message appears.
• The default data source depends on a public community feed; if it's unreachable, switch "source" to "blog" in config.json.
