01
Single-purpose, no scope creep
A micro-app has exactly one job. The brief, the constraints, and the success metric are locked before a line of code is written. That focus is what makes them fast to build and fast to use.
Web design for micro-apps
A focused tool that does one thing and does it without friction.
Brand-native micro-apps for founders and product teams who need a single-purpose utility — an interactive tool, a quiz, a calculator, a slot machine — built to the same standard as a product, not bolted on as an afterthought.
- What this is.
- Nerd Prescribed builds single-purpose micro-app web experiences for brands and founders — typically €1,500–€4,000 depending on complexity. No template, fast turnaround, brand-native.
- Who it's for.
- Founders, indie brands, and product teams who need an interactive tool for their site — something that does one job very well, runs fast, and feels like it belongs to the product.
- What it costs.
- A simple utility with no auth runs €1,500–€2,500. Add user state, saved results, or third-party integrations and the budget is €2,500–€4,000. Complex micro-apps with auth and billing sit at the high end.
- Bottom line.
- Nerd Prescribed built ERism — an outfit slot machine for SOME DOSE live since 2024. If you have a product moment waiting to happen, come scope it.
Features
What makes a micro-app worth building
02
Brand-native, not bolted on
Micro-apps built as a Typeform embed or a Notion page look like someone else's product. A custom-built one uses your typeface, your colours, your animation language — it extends your brand rather than interrupting it.
03
Fast to build, fast to ship
Most micro-apps scope to 2–5 weeks. The constraint of doing one thing well means less to build, less to test, and less to maintain. Small blast radius if something needs changing later.
Pricing
What micro-app builds typically cost
Most micro-app builds land between €1,500 and €4,000. Complexity is driven by state management, integrations, and auth requirements.

|---|---|
| Simple utility (no auth, no state)Interactive tool, quiz, or calculator — no account, no saved state, no backend | €1,500–€2,500 |
| With saved state or shareable resultsAdds localStorage or session persistence, shareable result URLs, or lightweight DB | €2,500–€3,500 |
| With auth + third-party integrationsLogin, saved history, API hooks (email capture, Stripe, Airtable) | €3,000–€4,000+ |

Common questions
What is a micro-app?
A micro-app is a single-purpose interactive web experience — a tool, quiz, calculator, generator, or utility that does exactly one thing and does it without friction. ERism is an example: an outfit slot machine that runs on somedose.com/erism, prescribes one full look per spin, and has zero accounts, zero onboarding, and zero decisions.
How long does a micro-app take to build?
Most micro-apps scope to 2–5 weeks. The constraint of doing one thing well means there is less to build and less to test than a full product. I work on one project at a time, so the timeline doesn't slip.
Can I add it to my existing website?
Yes. A micro-app can be deployed as a subdirectory of your existing domain (e.g. yourbrand.com/tool), a subdomain (tool.yourbrand.com), or a standalone URL. It can also be embedded in an existing page via an iframe if needed.
Do micro-apps need their own hosting?
Vercel hosting is included in the care plan (€500/mo). Most micro-apps with no backend are eligible for Vercel's free tier permanently — I will advise at scope time. If your micro-app has a database or auth, hosting is costed into the build.
Can I turn a micro-app into a full product later?
Yes — that's actually the cleanest path. Build the core interaction as a micro-app, validate it with real users, then scope the full product from there. ERism started as a micro-app and could become a standalone product if the brand chose to expand it.
