In development · not yet released

Dex Companion answers the question and gets out of the way.

A reference app for monster-collecting RPGs, built for my kids and me while we're actually playing. Type matchups, evolution requirements, base stats, and which version a species appears in — the things you currently stop the game to go and look up on a website full of advertising.

The measure of success is how little time you spend in it.

The problem is friction, not information

All of this information already exists. The trouble is the retrieval: you're mid-battle on the sofa, you need to know what a type is weak to, and getting the answer means leaving the game, opening a browser, loading a page heavy with ads, and scrolling past a preamble to reach a table. By the time you're back you've lost the thread of what you were doing.

With three kids playing at once, that friction multiplies. Somebody is always asking someone else to look something up.

A companion app should make the game better, not compete with it for attention.

So the design target isn't engagement. It's time-to-answer. Open, search, read, close — reachable one-handed, fast enough to use without pausing the conversation.

The interface

Search — the root screen
Detail — evolution carousel
Collection progress

Structural diagrams of the layouts, not screenshots. Real captures will replace these when the interface settles.

How it's built

Bottom-reachable
Every primary action sits within thumb reach on a large phone. You should be able to use it one-handed while holding a controller in the other.
Version-aware
Evolution requirements and availability differ between game versions, so the data model treats version as a first-class dimension rather than an afterthought. Answers are correct for your game, not an average of all of them.
No Surprises mode
An optional setting that hides evolution paths you haven't encountered yet. The discovery belongs to the game. A reference app shouldn't spoil a nine-year-old's playthrough by being helpful.
Split view from day one
Built on NavigationSplitView rather than a stack, so it collapses to a single column on a phone and expands properly on iPad without a second codebase.
Offline, account-free
Native SwiftUI, local storage, no sign-in, no analytics. It works in the back of a car with no signal, which is where a lot of handheld gaming happens.

Deliberately unmotivating

There's a gamification framework called Octalysis, from Yu-kai Chou, that maps human motivation onto eight core drives and splits them into two halves. White Hat drives — meaning, accomplishment, creative feedback — leave people feeling capable. Black Hat drives — scarcity, unpredictability, fear of loss — produce far more immediate action and leave people feeling anxious.

A companion app is an unusual case, because the game it accompanies is already running a very effective Black Hat engine. Collecting rare things, random encounters, the pull of the next one — that's the whole appeal, and it works. It isn't my business to add a second layer of it.

So Dex Companion has no daily anything. No notifications, no streaks, no reason to open it except that you have a question. Collection progress exists because tracking what you've caught is genuinely useful, and it's presented as a plain record rather than a bar that nags you toward completion.

The app should be forgettable when you're not playing. That's the goal, not a compromise.

Questions I'd ask

When is it coming out?

Unknown. Key Quest is ahead of it in the queue, and this is a nights-and-weekends studio. The design work is largely done; the build is not.

Is this official, or affiliated with a game publisher?

No. It's an independent reference tool, built by one person for his own family. It isn't endorsed by, affiliated with, or connected to any game publisher, and it doesn't use their artwork.

Why not just use a website?

You can, and for a lot of people that's the right answer. The case for an app is speed, one-handed use, offline access, and not being surrounded by advertising while a child is reading it over your shoulder.

Will it need an account or a subscription?

No account. Pricing is undecided, but a subscription for a reference tool that works offline would be hard for me to justify.

If you want to know when it ships

No signup form, no newsletter. Send me an email and I'll reply when there's something real to report.
