My Cellarium a digital wine vault
A digital wine vault: premium wines bought online and stored by partner wineries, with the whole collection always in view in the app.
Mobile apps
Apps, from first idea to launch
We plan and build your mobile app, then look after it and keep developing it. If you already have a plan, a prototype or a finished app but nobody to take it further, we take it over and carry on from there.
For companies launching a new mobile product, and for those whose existing app has nobody left to maintain it.

From the first plan to long-term care
We have worked on several kinds of mobile apps: a training app that uses motion sensors, a digital wine vault, and apps built by other developers that we took over to look after long term. That is why we choose the technology that fits your product and budget.
- Ludus: a training app that counts repetitions in real time with the phone's sensors. We designed and built it together with the team at Appic in London.
- mycellarium.hu: a digital wine vault, on mobile and on the web.
- Cirrhy: an app built by another developer that we took over. Since then, we have handled the long-term maintenance and shipped the updates for iOS and Android.
- We draw on more than 20 years of general software development experience, plus hands-on iOS and Android development practice.
What does it cost?
We use the same pricing bands for three project sizes across every service area:
-
MVP or pilot
HUF 3–8M
Typically 4–12 weeks
-
Production system
HUF 8–20M
Typically 3–6 months
-
Platform
from HUF 20M
From 6 months, quoted individually
Before every project: Review and technical plan — HUF 0.9–1.5M, 2–3 weeks.
What each range includes, and what drives the price
Prices are net of VAT and indicative. The final price is set after the review.
Already have a plan or a prototype?
If you have already worked out your idea with ChatGPT, Claude or another AI tool, we don't need to start from scratch. We review the specification, the screen designs, the prototype or the source code, and tell you what can safely be built on. What works, we keep; what needs it, we fix or redesign.
When we are not the right choice
- If a good website that works well on phones does the job, don't pay for an app.
- If the lowest price is all that matters, you will certainly find someone cheaper than us.
- If nobody on your side can decide on features and sign off finished work, the project will slip, whoever builds it.
Frequently asked questions
Which technology should we choose?
It depends on the product. If the app relies on special hardware features, background processes or platform-specific capabilities, we look at whether separate native iOS and Android versions are justified. For many business apps, a shared codebase is the more economical choice: it is faster to build and cheaper to maintain.
Do I need my own Apple and Google developer accounts?
Yes, and it is worth opening them in your company's name, so the app stays yours. The Apple developer account costs USD 99 a year, Google Play a one-off USD 25. We help you set them up.
Will you take over maintaining an app someone else built?
Yes. First we review the code, the accounts and the release process, and tell you in writing what state the app is in. That shows whether it is worth continuing, or whether some parts are better rewritten.
How long does store review take?
At Apple, typically a few days. On Google Play, new personal developer accounts must run a closed test with at least 12 testers for 14 days before the first release. Company accounts are exempt. A rejection also costs time for the fix and a second review, so we prepare the store listing and the reviewer notes during development.

At Appific, we have used an AI-agent-based development system since 2024: the agents work within strict technical rules, while a specialist decides on the system's structure and accepts the result. I have more than twenty years of experience as a software developer and architect; I previously worked on fintech systems. I now put that experience to use designing systems, reviewing them and managing their technical risks.
