Just Button

Just Button gives you exactly one thing: a button. aleros.io's free iOS experiment, on the App Store since September 2021, states its own premise with a shrug: you tap the button, and the number goes up. It is, after all, just a button. What the app does with that single input is the whole game, and the game is a subversive little puzzle box that takes roughly an hour to stop being a joke and start being interesting.

What the loop feels like

You press. Sometimes you hold. The number climbs, and the interface stays aggressively, comically minimal, no ads, no in-app purchases, no data-mining, just a button and your thumb. The tedium is the design, and it is deliberate. That's Just Button.

Then the surface cracks. At certain thresholds the minimalist screen admits to having secrets: narrative fragments appear, the style shifts, easter eggs and hidden sequences surface, and the input you thought you understood, pressing, holding, rhythm, starts rewarding experiments you have not tried yet. That's Just Button.

The systems doing the work

Single-Input Interaction is the entire verb set: press, hold, and interact with one central button. Milestone Unlocks drive progression through cumulative interactions and uncovered hidden sequences rather than XP or skill trees. Unfolding Complexity introduces secret puzzles, mini-games and easter eggs as thresholds are crossed, and the experience layers in subtle feedback loops involving three distinct characters tied to the button's state. The community's advice amounts to systematic experimentation: try prolonged holds, rhythm tapping, and checking back after time passes, because the game intentionally presents as empty until you push.

Where it stumbles

The honest gap is documentation: no independent criticism coverage exists for this one, and its criticism research pass came back empty, so the read here rests on the developer's own material and the mechanics pass. The design-level stumble is the same as the design: the first impression is a near-empty screen, and players who want clear goals, visible numbers doing interesting things, or anything to do with both hands will bounce inside five minutes and be right to.

Playing it today

Free on the App Store for iOS, rated highly by its small audience, with its no-monetization pledge intact. For the same one-idea-taken-seriously energy in a browser, Universal Paperclips remains the genre's monument, and Progress Quest is its ancestor.

The verdict

A small, free, oddly committed experiment: one input, zero monetization and genuine secrets. It will bore most people in five minutes and delight a specific kind of curiosity for an evening. The button knows what it is doing. Do you?
