### 4/5 — Good but

*2026-02-23, version 1.9.8*

Why are the videos not appearing ? Just wondering

### 3/5 — Can’t sign in to Lego account anymore

*2025-08-07, version 1.9.8*

So the app is so great and awesome but there’s one problem when I try to sign into my Lego account I sign in but then it doesn’t show on the Lego boost that I didn’t sign in. I do it multiple times, but never works. Plus, I even tried to re-download the app. But it never works. So even when I try to sign in it shows Lego life but Lego life is deleted so they puted a Lego play app. So if they updated Lego life. Why didn’t they update Lego boost? That’s why I’m not signing in. Please fix that Lego.

### 4/5 — 2 petits problèmes

*2025-05-25*

L’application est vraiment très bien malgré 2 petits problèmes : le premier est sur le lego de la glace ou les commandes pour lever et baisser la pince sont inversées ce qui est très perturbant.
Le second est le fait que je n’arrive pas à accéder au petite vidéo.
Si cela pouvait être réglé, se serait vraiment bien.

**Developer response:** Merci d'avoir pris le temps de nous partager votre expérience sur l'application. Nous aimerions en savoir plus concernant ces deux problèmes ! Contactez nos experts via LEGO.build/Service-Apple pour qu'on regarde ça ensemble. 🔎 - Marine, Service Client LEGO®

I’m trying to turn the Lego boost’s external motor but no matter what, it won’t turn. I’ve tried many ways to see what is the problem, but it looks perfect, almost brand new actually. But it won’t turn. It’s getting me frustrated. Please try to help me figure out what is the problem. :(

## Most critical reviews (10 lowest-rated)

### 1/5 — The worst ever

*2026-01-12, version 1.9.8*

Full of glitches.  Way to slow for the price of the let sets. Not worth it.

### 1/5 — Hub

*2024-11-12, version 1.9.8*

When I got the set it did not have the right hub and it was missing parts so I can not us it.

### 1/5 — Lego boost

*2024-06-25, version 1.9.8*

So slow to download like I’m tryna do this thing for my teacher and it don’t even download

### 1/5 — Firmware will stop updating

*2023-11-29, version 1.9.8*

Worked for awhile but now requires a firmware update every time you start the hub motor

### 1/5 — The app doesn’t open

*2023-02-19, version 1.9.8*

I can’t open the app.please fix this

### 1/5 — Horrible app even worse customer service

*2022-12-27, version 1.9.8*

It’s so irritating when you buy a toy and then it never works nor does the customer service phone number… just a pathetic joke…why is Lego so annoying.

### 1/5 — Update Firmware is not Working !

*2022-10-28, version 1.9.8*

Me and my son are trying to update the firmware and it never work! Tried with iPhone 11 and 12, then using my son iPad 10.2 and no change! 
This is is a not acceptable and should be resolved for good.

### 1/5 — Firmware update as of June 2, 2022 is not completing

*2022-06-02, version 1.9.8*

Just opened the box to start this build with my son. Found that the firmware update of the Move Hub is stuck in an infinite loop, so I can’t get the firmware for the Move Hub updated and can proceed no further with this set. Disappointing.

### 1/5 — DON’T BUY LEGO BOOST!!!!!

*2022-02-06, version 1.9.8*

Honest review : this app is a complete crap. My kid is stuck on “updating firmware”!!!!!!!!

The company should reflect on selling crap at this exuberant price when the kit doesn’t work at all. I want to go back to the shop for a full refund.

### 1/5 — Difficult to use

*2022-01-09, version 1.9.7*

Took us an hour to get the Boost module connected. Of course, I didn’t know that was our problem, since there are so few actual words in the UI; the hieroglyphics were impenetrable, even to a lifelong Lego builder. After an hour of Googling, many resets, and 3 different devices, finally got firmware updated on the module, and we haven’t had any more connection problems so far.

### 5/5 — Technology in 2025

*2025-08-30, version 1.9.8*

I tested it in 2025 and I hate the 6 AAA batteries

### 5/5 — Good

*2025-08-20, version 1.9.8*

The Lego boost is really good, but I’m wondering where the Lego boot Star Wars app is in the App Store

### 5/5 — 제미있당

*2025-07-30*

너무 재미있어요! 집에서 코딩을 이렇게 싑게 할수있다니 너무 제미있어요!

### 5/5 — Easy to use

*2025-07-13, version 1.9.8*

I got a second hand Lego Boost set in July 2025. I wasn’t sure if this app would work based on the other reviews but it worked perfecly with my iPhone 14. It paired with the robot easily and I was able to work through all of the Frankie the cat programs without any issues.

### 5/5 — Best game ever!

*2025-04-06, version 1.9.8*

### 5/5 — Vernie

*2024-12-17*

I just built Vernie again after 6 years of him being disassembled. I don’t like how the update works with the Lego brain, but I sorted it out. Great app, but outdated but it’s like 6 years old now so I guess I can’t talk 😅 10/10 should remaster the creative toolbox Lego!

### 5/5 — Very good

*2024-09-03, version 1.9.8*

Goated

### 5/5 — works well but...

*2024-08-15, version 1.9.8*

This app is very fun to play with but I hope that the sounds would come out of the robots not the app but there are no other problems that I have noticed🙂👍

### 5/5 — Great!

*2024-07-22, version 1.9.8*
