Pokopedia
Finding out which habitat attracts a Pokémon, or what a recipe needs, usually means digging through scattered forum posts mid-game. Pokopedia puts it all in one app: a Pokédex of 360+ Pokémon, 250+ habitats with the exact blocks, items, time of day and weather each one needs, and every cooking recipe with its ingredients and effects. Mark what you've befriended, built and cooked, and keep a separate profile for each save file. All data is bundled, so it works offline, and it's available in 8 languages. Free, with no content behind a paywall.
