Slow AI-built app? We measure it and fix it
Every library the AI added went into the first load. Our team measures in production, identifies what weighs and fixes it.
We measure the app on mobile, in production, and fix what makes the screen slow or jumpy.
Before: piece by piece
After: all at once
Measured in production, 3 runs, median.
1The problem
Signs the app is already heavy
- The app takes a long time to open on mobile, even on a good connection.
- The screen shifts while it loads, and users tap the wrong button.
- Lists and reports get slower as the database grows.
2What we do
What the service includes
Honest measurement
Mobile Lighthouse in production, 3 runs, and the median.
Initial JavaScript
We remove from the first load whatever the first screen does not use.
Images, fonts and CLS
Images in WebP or AVIF and reserved space so the screen does not shift.
The database, when it is the cause
Slow queries and indexes, when the screen is slow because of them.

About the diagnostic →Frequently asked questions
Frequently asked questions
Do you guarantee a PageSpeed score of 100?
No. We guarantee honest measurement, before and after, and fixing what weighs. The score varies between runs of the same code, which is why we use the median of 3.
What is CLS?
It is the sum of the screen’s shifts while it loads. When a button moves under the user’s finger, that is CLS. Google considers up to 0.1 good; we aim for zero.
The app only gets slow after login. Is that covered?
Yes. We measure the internal screens with a test account you create. If the slowness comes from the database, the fix covers the queries.
Start with the diagnostic.
The diagnostic costs US$ 79, paid by payment link. We deliver the report in 2 business days and walk you through the findings in a meeting. The fee is credited if you hire the service within 15 days. Everything we set up stays in your name.
Reduces the risk, does not eliminate it. We only work with the app’s owner, with proof of ownership.
