Focus Tycoon
Focus app · iOS · Shipped
A timer that pays you. Every uninterrupted minute raises a street, a tower, a district you keep forever.
On the App Storethe resonance that remains when the sound has stopped
A studio of one: Alberto Valverde, software engineer with a master's in applied Artificial Intelligence. I design, build and ship every app end to end. One is on the App Store; two are still in the workshop.
The name
余韻
In Japanese, 余韻 is the resonance that lingers after a sound has faded. The echo of a bell nobody is ringing any more.
That is exactly what I want from an app: something left over after you close it. A feeling, a habit, an idea still sounding quietly.
The background of this page is a real wave simulation: every move you make drops a ripple that spreads, collides with the others and dies away. And the colour runs from the deepest indigo to paper as you scroll.

Keeping a habit alive on the days you don't feel like it. A missed day isn't failure — it's weather.

A home for ideas collected faster than they can be used. Still without a final shape, deliberately.

Focus apps punish you. Break the timer and you lose the streak, kill the tree, fail the session. Guilt is a terrible engine — it works for a week, then the app gets deleted.
Flip the reward. Focused time is currency, and that currency builds a city that is permanently yours. Nothing is ever destroyed, so coming back after a bad week feels like returning to something you own, not something you ruined.
Sessions people finish and — the number that actually matters — people still opening it in month three.

Method
Idea to App Store
Start from a problem I actually have. If I wouldn't open it daily, it doesn't get built.
Every screen in Figma before a line of code, including the empty and error states nobody plans for.
Ship to TestFlight early, watch real people use it, cut whatever they never touch.
Store page, screenshots, icon, updates. Launch day is the start of the work, not the end.
Studio
The person behind it
I make apps alone, on purpose. No team, no handoffs, no telephone game between design and code.
That means I sketch the idea, design every screen, write the Swift, draw the icon, shoot the screenshots and press submit. Slower on paper, faster in practice — the decisions that usually die in a handoff just get made.
It also means the details nobody asks for get done anyway: the animation curve, the empty state, the haptic that lands exactly on the beat. Those details are the product.
By day I work at Mondo Tracking (Miami): operations, technology and support for fleets — ELD, GPS, dashcams and the automations that hold it together. By night, yoin labs. Software engineer (UDLA) with a master's in applied Artificial Intelligence.
