Finding the Itch

There is a whole genre of advice out there that says “Generate one hundred app ideas, then pick the best one.” I am going to tell you why I think that advice is backwards.

The problem with idea generation as a strategy is that the ideas you generate are always a little bit borrowed. They come from the shape of the ideas you have seen recently. They come from TikTok trends, from Twitter threads, from whatever startup newsletter you read last week. They are adjacent to culture, which means they are adjacent to competition, which means they are the ideas a dozen other people also generated this week.

Idea generation rewards breadth. Building rewards depth. The two are in tension.

The builders I know who ship consumer apps that actually stick do not generate ideas. They find their itch. An itch is not a generated idea. An itch is something you cannot stop noticing in your own life: some friction that bugs you every day, some stupid workaround you have been doing for years, some feature you keep wishing a thing had that it does not have. An itch is pre-cultural. An itch lives in your body, not in your notes app.

The difference between an idea and an itch is this: you can forget an idea. You cannot forget an itch. If you have been annoyed by the same thing for six months and nobody has fixed it and the thought keeps coming back to you, that is an itch. That is the one.

The MemeScanr Itch, in Full

I told you at the start of this book about the Tuesday my camera roll broke me. Let me tell you more about why that was an itch and not just an idea.

I had been complaining about my camera roll for about two years before I started building MemeScanr. Not loudly. Not productively. Just quietly, to myself, every time I opened the Photos app and felt the familiar wave of ugh, this is too much. I had 14,823 photos. I had tried the built-in Duplicates tool in iOS 16+ and found it technically correct but spiritually unhelpful. It detected exact duplicates but not the forty-seven near-identical selfies from the same night, and it definitely did not know what a meme was. I had downloaded two competitor apps and uninstalled them within a day because they felt like tax software. I had thought, at least a dozen times, someone should make a cleanup app that does not feel like homework.

That last thought is where an idea becomes an itch. It is the moment the phrase “someone should” becomes “I wish this existed so badly that I would actually use it.”

When you find yourself thinking “I wish this existed” about the same thing more than three times, pay attention. That is your body telling you where to dig.

Here is the clearest sign of an itch vs an idea: when you describe an idea to a friend, the friend nods politely. When you describe an itch to someone, they recognize it immediately and tell you about their version of it. Itches are shared. They are invisible until someone names them, and then everyone in the room recognizes them.

The first person I said it out loud to was my daughter, Ava. She was seven, and she looked at me like the problem was obvious. “Yeah,” she said. “There is too much stuff on phones.” That simple reaction stayed with me. It reminded me that the problem did not need a complicated explanation. It was real enough that even a child could feel it.

The Feeling Filter

Here is an exercise. List every idea that has been living rent-free in your head for the last three months. Do not filter yet. Just list them. Five, ten, twenty, whatever is in there.

Then, for each one, ask: what feeling would a user have after using this, that they could not get anywhere else?

If your answer is “productive,” that is not a feeling. That is a category. Try again. If your answer is “organized,” that is not a feeling. That is a state. Try again. If your answer is “like my phone finally belongs to me again,” now we are getting somewhere.

The feeling filter is brutal. Most ideas do not survive it because most ideas are features in search of a feeling. But the ones that do survive are the ideas that carry their own marketing story. When you know the feeling, the positioning writes itself, the screenshots write themselves, the voice writes itself.

MemeScanr’s feeling, once I got honest about it, was not “a clean camera roll.” That is a state. The feeling was relief. Specifically, the relief of being seen by a tool that understood how bad it was and was not judging me for it. That is the thing no competitor had, and that is the thing that drove every single design decision from that moment on.

Who It Is For (and Who It Is Not)

Once you know your feeling, you need to know your person. Not your demographic. Your person.

Demographics are lazy. “Gen Z” is not a person. “Women 25-34” is not a person. “iPhone users” is not a person. These are marketing segments, which means they are the level of abstraction at which a product dies.

Your person is one specific human. A composite, sure, drawn from five or ten real people you have observed, or ideally spoken to. But the composite should feel specific. Specific enough that you could write a short story about a day in their life.

Here is my person for MemeScanr:

She is 24. She has an iPhone 15 Pro with 256GB of storage, of which 180GB is photos and videos. She takes an average of forty photos a day. Most of them are screenshots, memes, and outfit photos she never posts. She feels guilty about her camera roll the way some people feel guilty about their closets. She has tried the Apple duplicates tool and given up because it only found exact matches. She follows at least three cleanup/aesthetic accounts on TikTok. She is afraid that if she deletes anything, she will accidentally delete the one photo that matters, so she deletes nothing. She unlocks her phone ninety-two times a day and at least twice a day she says out loud “ugh, my phone is so full.”

Every decision I made about MemeScanr, I made with her in mind. The Tinder-style swipe review? Because she is on TikTok and Reels and is comfortable swiping. The Memory Lane feature? Because she is afraid of losing the one photo that matters, so instead of asking her to delete, I let her walk through her past and rediscover things. The Phone Therapist? Because she is Gen Z and she wants to be teased, not lectured. The on-device privacy? Because she does not trust cloud upload apps with her photos, and she is right not to.

Your person does not need to be my person. But your person needs to be one person, specific enough to picture, specific enough that you can hear their voice in your head when you are writing button labels.

Describe your itch in one sentence. Then describe your person in one paragraph. If you cannot do both, you are not ready to move to Chapter 7 yet. Stay here.
