Who wrote this comparison.
This comparison is published by OverFuture, a software company in Zaragoza that also builds mobile apps. Because we compete with these firms, we do not score ourselves, and our details appear separately in the ‘About us’ box. Nobody paid to be listed. If a fact is wrong, we correct it with the source in front of us. Last review, 10 November 2026.
How we scored each company.
A company qualifies if its website says it builds mobile apps for other businesses and it is based in Zaragoza or says it works here. Directories, profiles without a website of their own and agencies from other provinces with just a city landing page are left out. For each company we checked at least four facts, with a quote and a link.
| Criterion | Weight | How we check it |
|---|---|---|
| App development as a stated service | 25 | Services page on its website |
| Address in Zaragoza | 20 | Legal notice, privacy policy or contact page. 20 points for an address in the city, 10 for a declared presence in Zaragoza without an address here |
| Track record | 20 | Founding year, start date or years in business published by the company itself, not by its team or its founder. A Commercial Register date is given as a fact, without points. 20 points for 20 years or more, 15 for 10 to 19, 10 for 5 to 9, 5 for fewer and 0 with no figure |
| Apps with their own page | 20 | 20 points for two app cases or more, 10 for one and 0 for none. A tile on a shared page does not count |
Public reviews (15 points) will join the February 2027 review, with source and date. Until then the maximum is 85. Companies on the same score are listed alphabetically.
Sources and interest. We used each company’s website and, for Hiberus’s registration, Spain’s Official Gazette of the Commercial Register (BORME), all checked on 10 November 2026. OverFuture builds mobile apps in Zaragoza, which is why it is not ranked.

Company profiles.
Hiberus. This technology consultancy has its registered address on Paseo de Isabel la Católica. Its mobile team has built several apps, including Volveremos, promoted by Zaragoza City Council. Its home page says it has been a strategic partner of Claro for 20 years, so it scores 20 for track record. The BORME already lists the company in 2012. Its app case pages include AVIApocket, a fuelling app for Esergui-AVIA, and a loyalty and ordering app for Sweet & Coffee.
Imascono. The studio is on Calle Josefa Amar y Borbón. It chooses between a native app, a web app or a PWA depending on how each product will be used. It states 15 years in business. Its app cases have their own pages, such as an interactive app for a children’s recipe book and 3D Joints Tool, published on Android.
Desarrollo4App. It builds custom web and mobile apps. It says it works in Zaragoza and Toledo, but its legal notice places its registered office in Olías del Rey (Toledo), so it scores 10 for address. It states IT projects since 2013. It publishes posts for its own apps, such as NET Sonelco for Android and iOS, and a tyre-tracking app for Tyres Price, a Zaragoza company.
IDA. Integración y Desarrollo de Aplicaciones has its address on Calle Isla de Menorca. It lists web and mobile apps among its custom development services, alongside ERP integrations. It states more than 25 years working with management software in Zaragoza companies. We found no app case with its own page, so it scores 0 on that criterion.
Calat. Calat Sistemas y Comunicaciones works from Plaza Ortilla. It has service pages for Android and iOS apps and handles their publication on Google Play and the App Store. It presents itself with more than 15 years in IT. Its website shows no app cases, so it scores 0 for portfolio.
How to choose an app company in Zaragoza.
- Decide what the first version of the app must do and leave the rest for later.
- Ask for published apps you can download, and ask what the company did in each one.
- Ask whether the app will be native, cross-platform or web, and why that fits your use.
- Agree whose name the code and the Google Play and App Store accounts will be in.
- Compare maintenance and updates, not just the price of development.
