CHALK
{{ wordmark }}
Auto-logged VGC stats, straight off your screen.
CHALK watches Pokémon Champions while you play, reads the battle screen with on-device and logs every ranked match.
Four steps, and three of them are just playing.
Hit Start
Open CHALK, tap the tracker, then queue up. It can also notice Champions opening and offer to start itself.
Play your games
No overlay in the way, no second phone, no spreadsheet open on the desk beside you.
The match logs itself
On-device OCR reads the battle text: result, your lead, the opponent's revealed Pokémon, moves, items, abilities.
Read it back
Per-team win rates, lead pairings, usage and match up trends , or export the raw rows and log them yourself.
Features
Automatic match logging
Result, your team, the opponent's revealed Pokémon, moves, items and abilities, detected live from the battle screen.
Per-team stats
Win rates, lead pairings, Pokémon usage and matchup trends, broken out per team you run.
Team import
Two team-sheet screenshots or a Poképaste link, with Regulation legality checking on the way in.
CSV export
Every logged match as spreadsheet-ready rows, whenever you want them somewhere else.
No accounts, no server
Parsing, storage and stats stay on the phone.
The calc fills itself in while you're still deciding.
Open a page on your computer over the same Wi-Fi. HP, stat boosts, items, abilities and forms arrive from the phone as the battle happens — nothing goes through the internet.
Built on the NCP VGC Damage Calculator (MIT), credited in-app and on the calc page.
Nothing about your matches leaves the phone.
No sign-in, no analytics, no ads, no backend. The developer never receives anything.
Screen capture runs only while tracking is on. Frames are read in memory and discarded.
Matches and teams live on-device. Delete them in-app, or uninstall and they're gone.
Sprite images (and a paste URL if you import one). There are no other destinations.
