The Same App, With Less CPU
Twenty thousand posts, two phones, one CPU gauge each. What happens when you rebuild how an app renders instead of asking builders to optimize it.
Here's the most honest demo I know how to give. Same feed. Twenty thousand posts. Two iPhones side by side, each with Xcode's CPU gauge running live. On the left, an app built with Classic Adalo. On the right, the same app generated by Ada — and nobody tuned it. No hand optimization, no tricks. Just what Ada produces out of the box.
Watch the two "usage over time" graphs while the lists scroll. The Classic app runs hot the whole time — the CPU never gets a break. Ada's graph comes in bursts: it works hard when new content comes into view, then goes quiet.
Now watch the phones. On the left, cards scroll past empty while the device struggles to keep up. On the right, every card arrives with its image, and the next page loads in behind you.
The numbers
Across our measurements, apps generated with Ada use:
- 20% less CPU than apps from our previous builder.
- Up to 32% less CPU while typing — the interaction where people feel lag the most.
Why this matters more than the AI
It's easy to talk about Ada as "the AI that builds apps." But an AI that generates heavy apps just gets you to a slow app faster. The thing builders actually feel — on a mid-range Android, on bad signal, in front of their own customers — is how hard the phone works.
For years, the fix for a slow Adalo app was education: don't nest lists, watch your screen complexity, run X-Ray. That helped. But it put the burden on the builder. With Ada, we moved that burden into the platform. The fastest app should be the default one, not the one built by someone who read the right blog post.
What you don't have to do anymore
I'm not going to walk through the internals here. What matters is the outcome for the person building: none of this asks anything of them. There's no setting to turn on, no pattern to memorize, no audit to run first. The work happened once, inside the platform, so it never has to happen again inside every app.
"Not optimized" is the point
The label on the right side of that video is deliberate. We didn't build a showcase app and polish it for the camera. That's an ordinary Ada app, and it's the baseline every builder now starts from.
That's the bar I want for everything we ship: the default should already be the good version.
