Pokemon Battle Journal

A .NET MAUI app for logging and analyzing Pokémon TCG battle records on Windows and Android.

Record matches, track win rates, and review your performance against specific archetypes. Everything is stored locally — no account, no sign-up.

What it does

Match logging — BO1 and BO3 formats, with per-game results, tags, notes, start and end times, and the coin flip.
Archetype picker — live meta deck list fetched from limitlesstcg.com on launch, with a searchable dropdown and deck images. Falls back to local defaults when offline.
Trainer stats and charts — win rate, streaks, average match duration, and eight charts: matchup matrix, win rate over time, most played, archetype win rates, opponent performance, tag usage, match length, and the first-turn split.
BO3 tab switcher — progressive Game 1 / 2 / 3 tabs. Game 3 appears only when the match result is split or both games tied, following official tournament rules.
Journal view — history of every recorded match, with expandable per-game detail.
Import and export — bring in battle logs exported from trainerhill.com, and write your matches back out as TrainerHill-format JSON or a full backup across every trainer.
Multi-trainer — create and switch between trainer profiles.

Building it

Requires the .NET 10 SDK and the MAUI workload. The repo covers the full toolchain, including the Appium setup for the Windows and Android UI test suites.
