### 5/5 — Great

*2025-03-29, version 1.8.25*

Great

### 3/5 — Looks like removed it

*2025-01-11*

I will removed from January 16th 2025 because it’s not available in your app because yeah I think developers remove the 3 Apps Lego Boost and MINDSTORMS and Connected train. Yeah but it’s came out 2018 because new app in 2025 now in 2018 and 7 years later it’s gone forever now new app 2025 and Today. Thank you now. Developer removed in January 2025

**Developer response:** The apps LEGO® Boost, LEGO® DUPLO® Connected Train and LEGO® MINDSTORMS® Inventor are still available to download via the App Store. For easier install, please make sure that your device is fully compatible with the apps (can be checked via LEGO.build/DeviceCheck-Apple) and that you have enough storage. If you need further help, please let us know via LEGO.build/Service-Apple. 🔍 - Marine, LEGO® Customer Service

### 1/5 — Awful

*2025-01-10, version 1.8.21*

Adds next to nothing to make a child play with the train

### 2/5 — This app could be much better

*2024-12-26*

I think this app is too infantile to be worth the effort. I don’t even want my son to play with a screen, so i definitely don’t want him to do that to play some lame game. Basically, this should have been geared more for adults who love be playing with their kid’s toys because trains are fun at any age.

The best part is that you can remotely control the train, but even then the controls are inconvenient because the screen is packed with too much junk.

This app should just focus on designing your own track and then see it traveled in first person view, somehow coordinated with the actual toy. That’s it.

**Developer response:** We're sorry to hear you didn’t enjoy the app. We appreciate your feedback, though.  We're always working hard on adding new features, and creating the best experience for our fans. We know some families may want to limit screen time, which is why your train can still push to start and stop – no app required.  - Todd, LEGO® Customer Service

### 1/5 — Too much storage

*2024-12-16, version 1.8.21*

My kid enjoyed this game lots, but then he wasn’t able to download any other games because this took so much. He was devastated. Now he lives on the streets as I enjoy retirement. It also takes so much battery life

### 3/5 — Very large file size

*2024-06-06, version 1.8.21*

Why does such a simple train control app need to be so large ?

### 5/5 — Renewed love

*2024-05-12, version 1.8.21*

My son recently rediscovered his train at 6, he’s had it since he was 3. He now invents new games with his train and incorporates other toys along with his duplo! He loves using the app to control it. Keep the updates coming and please make new tracks available in store and online!

### 1/5 — Bluetooth stopped working

*2024-03-19, version 1.8.21*

Tapping the app and train option no longer searches for a train using Bluetooth.

### 3/5 — Heavy as hell

*2024-02-22, version 1.8.21*

Why the app to control a little train should be 1.25GB?!

### 3/5 — Doesn’t work with two trains

*2024-01-23*

I have two Duplo trains, and two phones. I used to be able to have each of them connected, but right now, when I connect one train, the phone for the other train shows it disconnected. Power cycling the disconnected train causes the train that was connected to disconnect.

**Developer response:** Hmmm.that doesn't sound right. Feel free to get in touch with us at LEGO.build/Service-Apple and we'd be happy to troubleshoot with you. 📞 Henny, LEGO® Customer Service
