For the CTO and the head of product
We review the app on real iOS and Android phones and tell you what fails in your customer's hands and what App Store and Google Play would reject. Today we review apps built in Flutter.
You get each issue with its evidence and its priority. Scope and timeline are in writing before we start.

You don't need it if the app is an internal prototype that will never reach customers. And today we only review apps built in Flutter.
In the simulator, screens load and buttons respond. On a real phone you find the keys written inside the app, the push notifications that never arrive and the permissions the store rejects. In a Veracode lab benchmark (spring 2026), 45% of coding tasks completed with AI without security instructions came out with a known security flaw. Veracode sells security analysis.

In 30 minutes we look at what app you have and which screens matter most. Then you get in writing what is reviewed, what is left out and the timeline.
We test each flow on iOS and Android devices, by command and with touch gestures, and we read the code and the API the app uses.
You get the list of issues ranked by risk and we go through it with your team. Each issue says where it is and how to check it.

Shall we talk about your case?
A 30-minute meeting to see what you have and what to review first.
All three are useful, each for one thing. AI brings the volume and people bring the judgment: that is why our review uses an automated AI tool and senior developers supervise it.
The review is done by a team of senior developers, with many hours of development and of finding the mistakes AI makes when it codes. We know more than 1,200 review points. The automated AI tool goes through them, and people verify, direct and review.

José María Salido, founder of Sondeon, answers for it
We review mobile apps built in Flutter for iOS and Android, whether they were coded with AI or by hand, together with the backend they use. Websites have their own review.
Yes. We need the repository of the app and its backend and an installable build for iOS and Android. What we ask for is written into the scope before we start.
Sometimes yes, and you only know by looking at it. AI writes an app that works in the demo, but it does not know what the stores demand or how the app behaves on a real phone. The review tells you what is ready and what is not.
The 30-minute meeting is free. The rest depends on the number of screens in the app and on whether the backend is included. We go over it in that meeting, and you get the scope and timeline of our health check in writing before we start.
Yes, if you ask us to. The diagnosis comes first: the list of issues with their evidence and priority, which says what gets fixed and what is better rebuilt. The fix is separate and only happens if you request it, and your team can also do it with the list in hand.
It is the review of an app that is already built, before you publish it or your company comes to depend on it. Our health check tests it on real phones and reviews security, personal data, push notifications and what the App Store and Google Play require, and it is repeated periodically.
Your website's performance, visibility in search engines and in AI assistants (SEO and GEO), accessibility and security, measured on the real page.
The server side behind your app or your website: what the API exposes, what it protects, what headers it serves and what ends up in its logs.
PostgreSQL, Redis, Elasticsearch and RabbitMQ, in read-only mode: structure, indexes, slow queries, locks and connections.
The server your system will run on, reviewed before you go live: who has access, what runs on it and which limits break as you grow.
The Linux machines your system runs on, measured every few seconds, so you see a full disk or a stopped container before your users do.
Every call to your API measured, with its latency, its error and the screen that requested it, so you know which endpoint to optimize before traffic grows.
Fill in the form and we email you to set a day and a time. It is 30 minutes to see what you have and what to review first.
