Calm Sidelines
I coach youth soccer, and the parents around me keep asking the same questions. Should we do club. Is private training worth it. Why does everyone else seem to know. The answers exist, mostly in books nobody has time to read, so I put them behind five questions instead.
The problem
A parent of a four-year-old and a parent of a nine-year-old need completely different things, and nobody tells them which is which. So they take the default: push a bit harder, start club a bit earlier, shout a bit more from the touchline, review the game in the car. Every one of those is the thing most likely to end with a kid quitting at thirteen.
The good guidance is not secret. It is in development research and sports medicine guidelines that a working parent is never going to read at 10pm. The gap is not knowledge. It is that nobody serves it up for your kid, at this age, this week.
What I built
Five taps: how old, how long they have played, where they play, what else they do, and what is actually on your mind. Out comes a playbook for that kid: five-minute ball games for their age, what is going on in their head, which programs make sense, and what to say on the sideline and in the car.
Two decisions get their own guided checks, because they are the ones parents agonise over. Should we do club and is private training the right call. Both return a verdict with the reasoning that produced it, so you can argue with the logic rather than a score. It then builds a printable action plan: a few things for this week, a few for the season, one sentence to say and one to stop saying.
One HTML file. No accounts, no server, no analytics, and it makes zero requests to anything outside itself, fonts included. It works on a phone with no signal, standing on the touchline.
How it changed
- Sep 17A paragraph, then a planWrote the vision, had the plan argued back at me with its ten hidden trade-offs, and cut the idea down to one decision instead of three products.
- Sep 18Advice before softwareFour age bands of guidance in my own voice. The content was the work; the code was an afternoon.
- Sep 27Verdicts, not articlesThe two guided checks. This is the point it stopped being a web page and started being a tool.
- Oct 1Sourced, printable, per kidEvery factual claim verified against a primary source, an action plan you can put on the fridge, and support for more than one player.
What broke
My first instinct was the wrong product
I wanted drills and training tips, because that is what the market sells. It is also the thing that turns a parent into a second coach, which is exactly what the research says goes wrong. The product I wanted to build argued against the product I was building.
The name was taken, several times over
"First Touch" is one of the most used phrases in youth soccer. There is already a parent-facing platform using it, plus training businesses and registered marks. Caught before a dollar went on branding, which is the cheap time to catch it.
The printable plan could be used as a weapon
A four-persona test surfaced it: print a checklist and hand it to your kid, and a tool built to stop parents pushing becomes the training schedule they push with. It now says, at the top, that the list is for the parent and not for the kid.
I broke my own privacy promise for a typeface
Loading brand fonts from Google meant the page phoned out, after I had told parents it contacts nobody. Embedded the fonts instead. The page tripled in size and the claim became true again.
Five claims I only half knew
Heading rules, birth-month effects, specialization guidance. All roughly right from memory, none sourced. I flagged them as I wrote them and verified every one before anyone else read them. One book's author I could not confirm, so the author came off rather than being guessed at.
If it never tells you no, it isn't advice.Private training passes two of the hundred and sixty-two possible answer combinations. That is deliberate. A tool that flatters the parent would be worth nothing to the kid.
What I learned
The code was never the hard part. AI made the building cheap enough that the expensive thing became having a point of view and being willing to encode it: rec before club, the kid owns the decision, urgency is a sales tactic, private training answers the kid's pull rather than the parent's push. Those are opinions. Writing them as logic that returns a verdict means standing behind them in a way an article never makes you.
The second lesson was about my name being on it. The moment I added a page saying who wrote this, every loose claim in the app became mine. Verifying them took an hour and changed three of them for the better, because the real sources are more specific than what I remembered.
