The LEGO MINDSTORMS Robot Inventor App will be discontinued on October 1, 2026, with no further updates or support. Resources on LEGO.com will guide you in transitioning your play experience to the LEGO Education SPIKE Prime App. Note: A full 1:1 experience or firmware replacement cannot be guaranteed. Create intelligent remote-control robots and vehicles using interactive in-app building instructions, with the LEGO® MINDSTORMS® Robot Inventor App! For use with the LEGO MINDSTORMS Robot Inventor (51515) set, this companion app has everything you need to build Charlie, Tricky, Blast, M.V.P. and Gelo, each with their own unique abilities. Then get ready to code and play your way through 50+ challenging activities. A fun build-and-play experience As you construct each robotic toy using the step-by-step building instructions in the app, you’ll complete a series of fun coding activities along the way. But if you prefer, you can also download a PDF version. Coding, the fun way If you’ve ever used a visual coding environment, you’ll be right at home with the Robot Inventor App’s colourful drag-and-drop canvas based on Scratch. Each coding element is grouped into categories so you can quickly find what you’re looking for. As well as using the coding canvas to complete the 50+ activities included in the app, you can also code your own activities for an even greater challenge – or, if you’re a more advanced coder, you can also use Python. Take control The Robot Inventor App includes a remote-control feature so you can get your robot walking, dancing and firing with just a few taps! You can also customise it to create your own personalised controller. Learn while you play While you’re building, coding and playing with your robots, you’ll also be exploring, experimenting and learning. Advanced machine learning Using your device’s camera or microphone, you can train your models to recognise and react to objects and sounds… even your own voice! A community of fan models The Community section of the app lets you build and code a growing collection of fun models submitted by some of our fans. Share your cool creation If you’ve designed and built your own amazing robot, you can take a photo of it and upload it to LEGO Life for everyone to see. You can also get loads more inspiration from what others have created. Key Features: Intuitive drag-and-drop coding interface based on Scratch 50+ fun and challenging activities for beginners and more advanced users Machine learning with advanced object and sound recognition Community section with fan models and inspiration Hub to hub connection for extended play possibilities Help Centre with lots of tips for learning and exploring Text-based Python coding for more advanced users Bluetooth connectivity for wireless communication Remote control for instant action Consistent experience across iOS, macOS. Digital building instructions included in the app Kids gain STEM skills through playful learning IMPORTANT: This is not a stand-alone app. It’s used to build and code interactive LEGO robot toys included with the LEGO MINDSTORMS Robot Inventor (51515) set.

My 51515 set is second hand, but it’s high quality made it look as good as new. The app, however is kinda weird. I can’t put my stuff on the community section, and tricky’s basketball launcher is wired when you attach it to tricky, and one step of Charlie’s drum set is also wired. All in all, this gets 4.8⭐️s. ### 4/5 — Why are you discontinuing it? *2026-06-05* Why are you discontinuing the app, people paid lots for a product you want to technologically lock down. It was a good app ### 3/5 — Bugs *2026-05-30* Make those last bug fixes with the remote before you discontinue ### 5/5 — Mega *2026-05-20* Ich finde diese App Mega cool und habe sehr viel Spaß und Erfahrung mit dieser App. Aber warum wird die App Eingestellt?Was soll ich dann mit dem Roboter? Ich hab so viele Programme die dann weg sind. Find ich schade.😢 Bitte schnell antworten! Danke !! ### 1/5 — Not functional *2026-05-16* Lego mind storms was discontinued so pls fix this ### 2/5 — App update *2026-04-15, version 10.5.0* My class iPads won’t consistently connect anymore to my inventor robots anymore. Why is this? Would love for someone to directly email me at ksnickell at aurorak12.org. ### 5/5 — perfect, just some issues with my hub *2026-03-06* used this without problems for what, 3 years? now the new spike prime hub updat ehappened, and now it doesnt connect to either the app or the computer, idk which. also, i believe that this app is superior to the spike prime one, becuse of the controller extensions and hub to hub communication. also, i would love if someone could tell me if theyve had this problem before. ### 3/5 — Votre site bogue *2025-12-03* La Croix directionnelle et les boutons ne marchent plus. ## Frequently asked questions about LEGO® MINDSTORMS® Inventor ### What does the LEGO® MINDSTORMS® Robot Inventor App do?
