The Idea Behind Pulsefield: A Game You Feel, Not See

What if a game had no visuals at all — just vibration? Here's the story of how Pulsefield came to life, from a casual mention of haptic feedback to a fully designed haptic experience for iPhone.

Where Did This Even Come From?

I'll be honest with you: I don't know if Pulsefield is a good idea. Even as I write this, I genuinely have no clue whether anyone will ever find this app, download it, and actually enjoy it. That uncertainty has been with me the entire time. But let me tell you how it started anyway.

I knew from the beginning that I wanted to build something that felt different. Not another to-do app, not another flashcard tool — something that actually used the iPhone as a platform in a way that wasn't totally exhausted yet. I kept coming back to one question: what can a smartphone do that nothing else can?

Camera, GPS, touchscreen — all table stakes at this point. But then in March 2026, during a company event where all the remote people came into the office for the week, one of our German freelancers mentioned haptic feedback in a conversation. Almost in passing. And something clicked in my head that I couldn't shake loose.

The iPhone's Core Haptics framework lets you create continuous signals, modulate their intensity frame by frame, layer textures and patterns on top of each other. It's not just a buzzer. It's a whole tactile instrument sitting in everyone's pocket that basically nobody is using as a primary experience. Most apps give you a little buzz when you toggle a switch and call it a day.

What if the haptic signal was the game?

The Maze That Didn't Work

My first instinct was a maze. Classic, right? Drag your finger through corridors without touching the walls.

Except — there are no walls on a touchscreen. You can't feel them. You'd just pass straight through, and the game would have to punish you after the fact. That feels terrible. It feels arbitrary. You'd be playing a game where the feedback is always: "you already lost, here's why."

So I flipped it. Instead of defining barriers, I defined a goal. One hidden target somewhere on a blank screen. A handful of hidden mines scattered around it. Nothing visible. No walls. Just: find the thing, don't touch the bad things, do it entirely by feel.

That reframe was everything. Suddenly there was real tension — you're searching for something, and your only compass is vibration. The goal pulses with a warm, steady hum that grows as you approach. The mines push back with a harsher, electric, pulsing signal that escalates the closer you get. At very close range it becomes genuinely unpleasant in a way that makes you want to pull back.

That's Pulsefield.

Making Two Buzzes Feel Completely Different

The biggest design problem with a haptic-only game is obvious once you think about it: how do you make sure the player can tell the signals apart? Two different buzzes can feel confusingly similar, especially when you're concentrating.

I spent a lot of time on this. The goal and mine signals are differentiated on three axes simultaneously:

Texture. The goal is soft and organic. The mine is crisp and electric. Even at the same intensity, they feel like completely different materials.

Pattern. The goal is a smooth, steady crescendo — the closer you are, the stronger it gets, no interruptions. The mine pulses on and off. This is more important than it sounds: your nervous system is literally wired to register intermittent signals as alarming and steady signals as safe. The game hijacks that reflex directly.

Urgency. The mine's pulse rate increases as you get closer — slow at the edges, rapid and frantic right at the center. Plus short sharp "sting" accents that fire at very close range. It escalates. It's not subtle.

The result is that most players, with zero instructions, instinctively pull their finger back when they're near a mine. They don't know why — it just feels wrong. That's the whole idea.

What the Game Actually Is

You put your finger on a blank screen and drag slowly. Haptics guide you toward an invisible goal and warn you away from invisible mines. When you reach the goal, the field reveals itself — you can finally see where everything was and trace the path your finger took. Then it resets with a new layout.

Win five times in a row and the difficulty goes up: one more mine, tighter spacing. Your streak is your level. Lose, and you drop back. That's the whole game.

No ads. Ever. That was decided on day one. I hate ads in apps — even the "pay to remove them" kind. It just poisons the experience. I committed that no app I ship will ever have them, even if that means I make less money. We'll see how that philosophy holds up.

Honestly? I Still Don't Know

Will anyone care about this? I don't know. It's not a catchy concept on paper. "Haptic minefield navigation" is not exactly going to trend. But I think there's something real here — a pocket of the App Store that nobody has really explored. A game that works differently at a physical level from anything else out there.

Or I'm completely wrong and this is a niche product for exactly zero people.

The name came naturally at least. Pulsefield. The field is invisible. The pulse is everything. The tagline — Feel your way through — says the rest.
