My kids and I are very disappointed. ### 1/5 — Whose Decision Was It To Change The App?!?!! *2026-07-12* The new app is ridiculous. My son has the older model and it’s his favorite. He doesn’t want the newer version and he hates the updated app. If it’s not broke, there is no need to fix it and there was no need to change the app. It was much more engaging with a better variety of activities and controls. Everything everyone else is saying is absolutely true. This has been a huge disappointment for my kiddo and my pockets. If I pay for an item, I expect to be able to utilize it entirely and to its fullest capability. It’s a little insulting that you’ve removed that option after already receiving full price. Would it have been impossible to keep the old app available as well? Lego…do better! **Developer response:** Thank you for leaving your review and we’re sorry to hear that the new LEGO® DUPLO® Trains app has affected your son's play experience. Feedback like yours really helps us improve the app as we try our hardest to create fun and engaging ways for builders to play. If you wouldn't mind sharing more details, please reach out to us at LEGO.com/Service. We would love to know more. - Priv, LEGO® Customer Service ### 1/5 — Leider wirklich schlecht *2026-07-12* Ich verstehe es nicht, die alte App war nicht perfekt, aber die neue ist ein absolutes Downgrade. So wird ein glücklicherweise haltbares Spielzeug per Software künstlich nutzlos gemacht. **Developer response:** Hi! Danke, dass du dir die Zeit genommen hast, um uns eine Bewertung zu hinterlegen. Wir geben dein Kommentar gerne an das Entwicklerteam weiter. Falls du Fragen hast oder weitere Details mit uns teilen möchtest, dann melde dich bitte über LEGO.build/Service bei uns. 🙂 - Henny, LEGO® Kundenservice ### 1/5 — Terrible update loss of experience *2026-06-08* Absolutely horrible update for this train set. It has made it a really poor playing experience for the old red trains with lack of interactive buttons, speed control, action blocks. Seriously bring back the old app. **Developer response:** We’re sorry to hear that the new LEGO® DUPLO® Trains app has affected your experience with the red trains. We’re always working to create fun and engaging play, and feedback like yours really helps us improve. If you’d like to share more details about what’s not working for you, please reach out to us at LEGO.com/Service. - Coryne, LEGO® Customer Service ### 1/5 — Old app better *2026-06-07, version 1.0.0* The old app was much better the new app has no Games. So boring ### 5/5 — I Like Trains *2026-05-21, version 1.0.0* Next Update, Can You Add A Track Builder? ### 1/5 — New app not as good *2026-05-18* The previous app was much more fun, engaging and interactive. Made it feel like you were actually driving the train. The new app doesn’t give the same feeling just a bunch of pointless videos. **Developer response:** Thank you for your feedback! We're always looking for ways to improve our apps, and sharing your experience is very valuable to us. We really appreciate your patience and support! - Redd, LEGO® Customer Service ### 1/5 — Honteux *2026-05-02* À l’époque je laissais mes enfants jouer avec l’ancienne application aujourd’hui la mise à jour n’apporte plus rien de sympathique! **Developer response:** Merci d'avoir pris le temps de partager votre expérience. Si vous souhaitez nous en dire plus, n'hésitez pas à nous contacter via LEGO.build/Service. - Marine, Service Client LEGO® ### 1/5 — Old trains better *2026-04-06* Older trains app was much much better, please release it again **Developer response:** We’re sorry to hear that you aren’t enjoying the new LEGO® DUPLO® Trains app. We'd appreciate your feedback, please reach out to us at LEGO.build/Service, if you'd like to share your experience. – Priv, LEGO® Customer Service ### 5/5 — Amazing *2026-03-30* We really love the duplo train. We didn’t actually know that the app would allow us to control the train’s motion, sounds, and lights and that we would be able to record ourselves using the sound bricks. We just thought that the train looked cool in the store. The app is just awesome. We highly recommend this train for 2 to 3-year-olds. They will think it’s incredible. ## Frequently asked questions about LEGO® DUPLO® Trains ### What does the LEGO DUPLO Trains app do?
