App Check
Know how secure your app is within 5 working days
I inspect your app for security, database, hosting, backups and code. You get a plain-language report that says what needs to happen first.
€600Fixed price, excl. VAT
What I check
Six areas where apps built with AI are often vulnerable.
Secret keys
API keys and passwords that are visible in the code or in the browser.
Database and permissions
Whether users only see their own data, for example with Row Level Security in Supabase or the rules in Firebase.
Sign-in and access
Whether sign-in, password reset and admin pages are properly protected.
Outdated packages
Packages with known vulnerabilities (CVEs) and updates that have been waiting for a long time.
Hosting and backups
Where your app runs, whether there are backups and whether you can restore them.
Code and stability
Errors, slow pages and code that will fall over with the next change.
What you get
- A plain-language report, with every risk marked red, orange or green
- For every point what is wrong and what can be done about it
- A 30-minute call in which we go through the report together
- Within 5 working days after I have access
- Advice on the maintenance plan that suits your app
Does your app fit in the App Check?
The fixed price covers:
- One app
- Up to 15 screens or pages
- One database
- Up to 3 connections, such as payments, email or signing in with Google
Count the screens you can open in your app, such as sign-in, dashboard and settings. Bigger? Then you get a fixed quote first.
A maintenance plan afterwards? Then I credit the €600
If you start a maintenance plan within 30 days of the App Check, I deduct the full €600 from your plan. The App Check then costs you nothing extra.
Questions about the App Check
What is the App Check?
The App Check is an inspection of your app for a fixed price of €600 excl. VAT. I check security, database, hosting, backups, outdated packages and code quality. Within 5 working days you get a plain-language report with the risks ranked red, orange and green, and we go through it together in 30 minutes.
Does my app fit in the App Check?
The fixed price covers one app with up to 15 screens or pages, one database and up to 3 connections to other services, such as payments, email or signing in with Google. Simply count the screens you can open in your app, such as sign-in, dashboard and settings. If your app is bigger, you get a fixed quote first.
What happens to the €600 if I take a maintenance plan afterwards?
If you start a maintenance plan within 30 days of the App Check, I deduct the full €600 from your plan. The App Check then costs you nothing extra.
What do you need from me for the App Check?
Access to the code, for example through GitHub, and read access to your hosting and database, such as Supabase, Firebase or Vercel. Plus a short explanation of what your app does and who uses it. I help you share that access.
Do you fix the problems during the App Check?
The App Check is the inspection and the report. What needs fixing, I pick up afterwards: within the support hours of your maintenance plan, or separately for €100 an hour. You choose what gets fixed.
Know where your app stands within 5 working days
