European teams care about privacy, accessibility and craft — and expect their apps to reflect it. siddhesh.studio builds with GDPR and the European Accessibility Act in mind from the first wireframe, not as a last-minute checklist.
You work directly with one senior designer-developer, overlapping with your Central European working day, with weekly builds you can test and clear written updates in English.
CET working hours
Daily overlap with Central European Time for calls, reviews and quick decisions.
EUR pricing
Fixed-scope proposals in euros, paid by SEPA transfer or card.
GDPR by design
Consent, data minimization, EU-hosted backends where needed and a DPA on request.
Accessible from day one
Interfaces built to WCAG guidelines, ready for the European Accessibility Act.

- 01
iOS app development
Native iPhone and iPad apps in Swift and SwiftUI — fast, accessible and built the way Apple intended, so they feel at home on the platform from day one.
- 02
Android app development
Native Android apps in Kotlin and Jetpack Compose, tested on the real range of phones your customers use — not just the latest flagship.
- 03
Flutter app development
One Flutter codebase, two polished apps. The fastest sensible route to iOS and Android without the app feeling like a compromise on either.
- 04
React Native app development
Cross-platform apps in React Native and TypeScript — ideal when your team already lives in JavaScript, or when the app should share logic with your web product.
- 05
MVP app development
A focused first version that real users can download — scoped tightly, built properly and ready to grow, not a throwaway prototype.
- 06
App UI/UX design
Flows, wireframes and interfaces designed by someone who also writes the code — so everything you approve can actually be built, on time.
- 07
Backend & API development
Everything users never see but always feel: sign-in that just works, payments that never double-charge and data that’s there when they need it.
- 08
App maintenance & support
Apps are never really finished. A calm monthly plan keeps yours fast, secure and up to date — and keeps improving it.
- 01Week 1
Understand
We talk through the idea, who it’s for and what success looks like.
- 02Weeks 2–3
Shape
Flows, wireframes and a clickable prototype, while decisions are still cheap.
- 03Weeks 4–10
Build
Design and engineering in short cycles, with a fresh test build most weeks.
- 04Ongoing
Launch & stay
Store release, monitoring and steady improvements once real users arrive.
Maison — Boutique stays
2025Booking for a small collection of independent homes — slow to browse, fast to book.
Otto — Personal finance
2025Net worth, accounts and spending in one calm view, with bank linking and biometric sign-in.
Still — Journaling
2024A daily journal that works offline, syncs quietly and reminds you gently. Subscriptions from day one.
Mise — Restaurant ordering
2024Menu, ordering and checkout for a neighborhood restaurant group, with a kitchen dashboard behind it.
After a short call I send a fixed-scope proposal in EUR or USD. Most first versions are planned as 6–12 week phases, at a fraction of typical European agency rates.
GDPR is built in from the start: consent flows, data minimization, EU-hosted infrastructure where required and a data processing agreement on request.
Yes — there is daily overlap with CET, so calls, reviews and decisions happen within your working day.
Yes. Apps are built with localization in mind, so adding German, French, Dutch, Spanish or other languages is straightforward.
