Why it exists

A Pokédex you open every day, not only to look things up.

PocketDex is a Pokédex you open every day, not just when you look something up.

Around the Dex sits a small daily routine: a new wild encounter each date, habits that give your partner XP until it evolves, and a focus timer that plays like a wild battle.

How it works

Try it in a minute

  1. 1

    Open the app

    Go to juw12.github.io/pocketdex/ on your phone or desktop.

  2. 2

    Meet today's encounter

    The Today page shows the wild Pokémon of the day and your meadow.

  3. 3

    Focus to catch it

    Start a focus session; when the timer ends the Pokémon joins your Dex and your meadow.

What's inside

What lives in your pocket.

A full, offline Pokédex

1025 species with stats, matchups, abilities, evolution chain, chiptune cry and your own field note. Search by name, number, type or region.

Daily encounter

A new Pokémon each date, the same for everyone. Finish a focus session to catch it.

Focus as a wild battle

Pick 15, 25, 45 or 60 minutes. The Pokémon's HP drains while you work; the timer survives reloads.

Habits that level up your partner

Each tick gives your partner 40 XP and each focus minute 5 XP. Partners evolve at level 16 and 32, with a choice for branching evolutions.

A quiet 3D meadow

A low-poly clearing whose sky follows your local time. Drag to look around and tap a Pokémon to see it.

Field Dex camera

Turn a photo of something real into a 64 px sprite in a Game Boy, Pocket or colour palette, then save a 600x840 entry card.

A partner with feelings

Your partner is happy, sleepy, proud or misses you after days away, shown with small pixel emotes. Pet it for friendship hearts; catches and level-ups get their own little scene.

Quiz, team and trainer card

Who's That Pokémon silhouettes, a 6-slot team builder with matchup matrix, and 8 badges for real milestones.

Windows app and desktop buddy

PocketDex.exe opens in its own window with your saves, adds Start Menu and Desktop shortcuts, tells you when an update is out, and can let your partner walk along the taskbar. Download PocketDex-Windows.zip (22 MB, Windows 10 and 11).
