I don't build apps for "users." I build apps for workers, parents, and people who need tech that actually works. No "Pro" paywalls, no data-harvesting. Just honest software that does the job.
No Silicon Valley nonsense. No data harvesting. Just tools that work.
I'm Karl — a time-served bricklayer from Wakefield with years on construction sites. In late 2025 I started teaching myself app development from scratch. No computer science degree, no startup background, just curiosity and early mornings before the first shift.
ProjectSnapLABS is what came out of it. I build simple, honest software for people who work for a living — because that's who I am. No Silicon Valley nonsense. No subscriptions where a one-time price will do. Just tools that do the job.
If you've got a question, an app idea, or you just want to say hello — I read every email personally.

Reality-check your app idea before you spend real money building it.
Bring me your half-baked, weird, or "probably stupid" app ideas. That's exactly what this is for.
You tell me your app idea in normal language — no jargon, no pitch deck needed. I run it through my AppGapHunter process: I look at real apps already on the stores, dig into what their users actually complain about, and map out where the gaps and opportunities are for you. You get a clear yes/no/maybe on whether it's worth building, what would make it stand out, and a practical plan for launching it. Not just a fluffy AI report.
A plain English build / refine / don't build verdict with clear reasons. No waffle.
Which apps you'd be up against, what their users hate, and where you can do better.
Core features, rough screen map, and a phased plan — what belongs in version 1 and what can wait.
The main ways to reach your first users and how to talk about your app so it doesn't sound like every other one.
One report. Everything included.
No monthly fees. No upsells. No waffle.
"I come from a hands-on background, not Silicon Valley. I care about whether this will actually work in the real world."
"If I think you shouldn't build it, I'll say so — and tell you why."
There are no stupid ideas here — some of the best apps started as "this might be daft but…"
Tap the app you're interested in and I'll drop you a personal email the moment it's ready. No marketing list. No spam. Just a heads-up from me.
Your email goes straight to Karl. No automated sequences, no newsletters unless you ask for one.
