Pickup And an app we built for ourselves: LiveMirror, in React Native, for iPhone and Android (internal project, not published on the stores).
The complete mockup, screen by screen, comes with the quote. You go through it, you change it, then you decide. It is free.
The quote prices what you approved on the mockup. Anything outside it is discussed before any work starts.
React Native shares most of the code between both systems: one app to maintain, not two.
The same person from the mockup to the launch, with no project manager between you and the people who build.
Few studios publish their prices. Those that do, checked on 9 October 2026, give wide ranges:
Swiss Tomato counts in hours rather than francs: 300 to 1,000 hours depending on complexity. All three agree on three to six months for a first version.
What moves the price: the number of screens, user accounts, payments, notifications, connections to your tools (calendar, till, business software), the back office, and the number of languages.
What costs every year: Apple’s developer membership (99 US dollars, Apple), hosting the back office, and the upkeep new iOS and Android versions require. The studios above put it at 5 to 10 % (devedis) and 15 to 20 % (Studio Dahu) of the initial cost, per year. Google only charges a one-time 25 US dollar registration (Google).
At Voren, the price is fixed in the quote, before we start, based on the mockup you approved.
The detail, studio by studio, with store fees and upkeep: how much a mobile app costs in Switzerland in 2026.
What we build: apps for your customers (booking, loyalty, order tracking), for your teams in the field (routes, photos, signed reports), and business tools (quotes, configurators, internal documents).
What we don’t take on: large critical ERP systems, platforms with millions of users, games.
Voren is based in Saint-Gingolph, on the Valais shore of Lake Geneva. We travel anywhere in Switzerland, or meet by video call, in French or in English.
Every project is quoted after a conversation. The price is fixed before we start and held at the invoice: anything outside the scope is discussed before being started.
No surprise at the end of the project, no extra discovered at delivery.
It depends on the number of screens, user accounts, payments, connections to your tools and the back office. Swiss studios that publish their prices give wide ranges, detailed above on this page. At Voren, the price is fixed in the quote, before we start, based on the mockup you approved.
Swiss studios most often quote three to six months for a first version. The real timeline depends on the scope: the mockup sets it, and the quote states it.
Cross-platform (React Native) serves most booking, loyalty or field-service apps with a single codebase. Native is worth it when the app pushes the phone hard (live video, Bluetooth, augmented reality). An installable web app is enough for a simple internal tool, without the stores.
For the general public, yes. Apple charges a yearly developer membership (99 US dollars, shown in local currency), Google a one-time 25 US dollar registration. An app reserved to your staff can be distributed privately, without appearing in the stores.
Every screen of your app and the flow between them, designed for your use, delivered with the quote. You go through it before you decide. It is free, and nothing follows unless you want it to.
Where you decide, in Switzerland or in the European Union. An app processing personal data in Switzerland falls under the revised Federal Act on Data Protection (nFADP), in force since 1 September 2023.
Yes: the back office that feeds the app, and the web app when your users also work on a computer.
