### 1/5 — Doesn’t work at all

*2026-05-15*

Paid for the subscription and the app is stuck on processing for days now. No help from them.

### 1/5 — Ca sert a rien

*2026-05-11*

C’est à nous de tracer l’angle exact de la colonne, ce n’est tellement pas précis qu’à chaque fois j’ai une estimation différente alors que c’est la même écho.
À fuir ca n’apporte rien du tout

### 1/5 — Do not buy - does not work

*2026-05-01*

Do not buy! Waste of money! No support & every image I uploaded wouldn’t work, so frustrating!

### 1/5 — Just doesn’t work

*2026-04-23*

Installed it this morning and it has been over 10 hrs, it still says processing! The customer support is also not helpful! Absolute waste of money.

### 1/5 — Not working

*2026-04-23*

This app is not working for me, I paid but when I upload the photos it takes forever processing them and it never gives me a result.

### 1/5 — scam

*2026-04-21*

this is fake , i subscribed and it’s not working for me it’s not giving any result and just showing processing. please don’t use it

### 1/5 — Scammers

*2026-04-09*

The app takes your money and then when you upload a photo it says failed and doesn’t give a result. Would rate 0 stars if I could!

### 1/5 — APP nao funciona

*2026-04-09*

Voce vai pagar e após vai descobrir que o app nao funciona

### 1/5 — Don’t work don’t pay for it

*2026-04-05*

Never work can I get my money back?

### 1/5 — Don’t waste your money

*2026-03-29*

If I could give this 0 stars I would. I purchased this app and it never worked. It wouldn’t load any photos and would say failed to scan on absolutely every ultrasound photo I had. I then went to google to find better ultrasound images to see if it was my low resolution pictures but nope. They failed to scan even the clearest of Google ultrasound photos.    What a waste of money!!!!! This was supposed to be a fun experiment but its clearly just a scam
