RekvinApps is a studio in Slovakia. We build mobile apps for iOS and Android that use AI where it genuinely helps — on contract for business clients, and as our own products alongside that work.
How we work
We take AI products from idea to a listed app. Discovery and scoping, model selection and prompt design, the app itself on both platforms, billing, and the store submission at the end. You get one team that owns the whole thing rather than a chain of contractors handing work to each other.
We also take on existing apps: an audit against the AI Act, GDPR and the store rules, then the changes needed to pass. We work with a small number of clients at a time, and we are direct about which parts of an idea AI will do well and which it will not.
We build and run our own consumer products on the same stack we sell. It keeps us honest: we pay the model bills, we sit through the store reviews, and we find out what actually retains users rather than guessing on someone else's budget.
VibeCue is the first of them, live today.
What we do
One product, both platforms, plus a browser version for people who would rather not install anything yet.
Store listings, data safety declarations, age ratings and privacy labels. The part most teams underestimate, and the part that decides whether an app ships this month or next quarter.
Language models for the things they are genuinely good at, costed per call so the unit economics are known before launch. No claim in our listings describes something the software cannot do.
Billing that works across the App Store, Google Play and the web, with the tax and price differences between them handled properly.
English, Slovak, Spanish, French, German and Portuguese ship with the first release. Translation is not a phase two.
We instrument the funnel on our own servers instead of loading third party pixels, so we can see what works without a cookie banner.
An AI app can be rejected, restricted or fined for reasons that have nothing to do with whether it works. We treat the rules as a design input from the first sketch rather than something to patch before submission — and we do the same for client apps that were already built without them.
For existing apps we audit what is there, list what breaks which rule, and change it. The output is working code and the documentation the stores ask for — reviewed with your lawyer, not instead of one.
One example: covering faces on the device, before transmission. Blur can be reversed; an opaque fill cannot.
Our apps
Photograph a scene and get three openers written for what the person in it is actually doing. Faces are covered on the device first.
VibeCue is our first own product. More are in development, alongside the client work.
