One visual checklist
Mark each Pokemon as obtained, review missing species quickly, and use filters to narrow the collection down.
Track your Pokemon HOME Living Dex without spreadsheet drift
Use saved trackers to plan what belongs in HOME, what still needs catching, and which owned games are easiest for missing Pokemon.
Owned-game planning
Select the games you own so suggested obtainability can focus on realistic routes instead of every possible game.
Separate shiny goals
Keep a standard HOME Living Dex and shiny Living Dex as separate saved trackers when you want both goals.
