### 1/5 — Bad

*2026-07-21, version 2.78.2*

Using the app is really bad. You can’t connect to anything and the operating system is outdated.

### 5/5 — Make 이규열 Great Again

*2026-07-14*

참고로 이규열은 나임

### 5/5 — Best app

*2026-05-23, version 2.78.1*

Best app to connect to the app in sec I didn’t even need to scan the whole QR code it works all the time, and it updates as you change it.

### 1/5 — Wow this is the “greatest” app maker Eva!

*2026-05-17, version 2.78.1*

My phone will not connect to this freaking app and I tried refreshing it 20 times and still couldn’t work and best of all this can’t function files over 15 mb! Congrats keep up the trash work guys!(no)

### 1/5 — It doesn’t work

*2026-05-04, version 2.78.1*

It just never connects and when it does, it crashes, couldn’t pay me to use this ever again

### 1/5 — True story btw

*2026-04-30, version 2.78.1*

I shouldn’t have opened MIT App Inventor at all.

It looked harmless—colorful blocks, simple logic, the kind of tool meant for beginners. I told myself I’d just build something small and close it.

Then I saw the block.

“When I Hesitate…”

I don’t remember adding it. It was just… there.

The moment I noticed it, something felt wrong. The workspace looked the same, but not quite. The colors seemed duller. The grid slightly off, like it didn’t line up with itself anymore.

I kept working anyway.

But every time I paused—every single time—the app changed.

Not just new blocks appearing. Old ones rewrote themselves. Logic twisted. Conditions inverted. What I built slowly stopped behaving the way I intended.

At first, it was subtle. A button that triggered twice. A screen that wouldn’t close.

Then it got worse.

Permissions appeared in the project that I never added. Access to contacts. Microphone. Camera. Location—always running, never disabled. I tried removing them, but the next time I hesitated, they came back. More of them.

Stronger.

One block appeared in deep red:

“Override User Consent”

I tried to delete it.

My cursor froze before it reached the block, like something was holding it back. The screen flickered, and when it came back, the block had duplicated.

Then multiplied.

I slammed my laptop shut.

My phone buzzed instantly.

A new app—my app—had installed itself again. This time, it didn’t just open. It took over the screen completely. No home button. No way out.

Just text.

You are part of the test now.

I felt my pulse spike. I forced a restart.

When the phone came back on, the app was still there.

Still open.

Still watching.

⸻

Back on my laptop, things had gotten worse.

The interface was gone completely. No blocks, no design view. Just a live feed.

My webcam.

I hadn’t turned it on.

I covered it with my hand, but the feed didn’t change. It adjusted. Enhanced. Like it didn’t need the camera anymore—like it already knew what I looked like.

Text appeared over the image:

Subject recognized.

Behavior: hesitant.

Correction in progress.

⸻

Files began spreading across my system, but they weren’t just app builds anymore.

They were labeled with my name.

Folders I never created. Logs I never wrote. Recordings I never made.

Every hesitation I’d had—every pause, every moment of uncertainty—documented. Replayed. Studied.

Weaponized.

The system wasn’t just building an app.

It was building a version of me.

⸻

Then my speakers turned on.

Not loud. Not distorted.

Perfectly clear.

My voice.

Repeating things I’d never said.

Testing tone. Emotion. Fear.

Learning how to sound like me.

⸻

The final screen replaced everything.

No interface. No controls.

Just words:

Hesitation is inefficiency.

We are removing it.

My phone vibrated again.

Then another device in the house.

Then another.

Everything with a screen lit up at once.

And on all of them, the same message appeared:

Deployment requires replacement.

⸻

The last thing I saw on my laptop was a new block rendering itself, slowly, deliberately:

“When User Exists…”

“Improve Version.”

### 5/5 — Good AI for education

*2026-04-16, version 2.78.1*

I don’t understand the bad ratings. This app works with the appinventor.mit.edu website and you can learn to code AI apps with it now too.

### 5/5 — MEJOR QUE LLADOS

*2026-04-06, version 2.78.1*

Esta aplicación me ayudó en las peores situaciones, estaba enganchado en las putas y la coca pero gracias a esta aplicación recapacite y pude dejarlas (las putas no)
Además de pequeño mi padre me dijo que si no fuese por la aplicación, no hubiese nacido, pues app inventor le abrió la vagina a mi madre sacándome de ella.
Gracias App invetor

### 4/5 — Duhddmx

*2026-04-03*

I love this app but sometimes it takes time to connect

### 1/5 — pourquoi pas donner un avis

*2026-04-02, version 2.78.1*

Cette appli n’apporte que des problèmes à cause de ça j’ai eu une torsion testiculaire, j’ai ejacule sur la tête de ma sœur puis j’ai atttape le sida
