### 5/5 — This is what you need

*2026-08-21, version 4.3.7*

You can see everything on the Lego and it’s organized you can move the camera to see little things and is good that on smart play it shows you how to do everything so I recommend this to you

### 5/5 — Amazing help 5 stars

*2026-08-20, version 4.3.7*

sub2marshmellowblox

### 5/5 — Super easy

*2026-08-19, version 4.3.7*

With this app it gets easier you won’t make a mistake

### 2/5 — Why do you need an app? There are physical booklets.

*2026-08-19, version 4.3.7*

Just why do you need an app to build Lego? The physical booklets are fine.

### 1/5 — Still using awful broken layout

*2026-08-19, version 4.3.7*

Honestly didn’t think it was possible for Lego to continue making this app worse but I was mistaken, they’ve doubled down on the grid view and now even filtered sets are shown in the new style instead of. Normal list

### 1/5 — Used to be good

*2026-08-18, version 4.3.7*

This app used to be good to organize and see which sets were in your collection. The new home interface is terrible for seeing which ones you own or don’t own. Finding them is tedious and having to filter is terrible. Even when you go to add a new set, the list doesn’t have the icon to show if it’s in your collection already. You have to dive down into each one to see. Terrible updates. Not worth using anymore.

### 1/5 — Age ID verification

*2026-08-18, version 4.3.6*

You have to submit a real ID just to verify your age on a lego app to keep track of your stupid brick sets and build maps ARE YOU FREAKING KIDDING ME??? WITH KIDS WEBS SERVICE THAT HAS BEEN INVOLVED IN MANY DATA LEAKS??  STOP HUFFING PAINT LEGO

### 5/5 — Better than the real thing

*2026-08-18, version 4.3.6*

Way better for osd people like my self to make the pieces are perfect accurate.

### 4/5 — 4/5

*2026-08-18, version 4.3.6*

It wood be good if you could do more stuff

### 5/5 — Lego builder

*2026-08-18, version 4.3.6*

This is an amazing app it helped me understand where the pieces go and what to do with them. Good job for the people that made this app a thing
