I don’t have slow internet either. Then, you have to tap through like five nested menus to get to the kit my kid wants to build, and after tapping that… same story, waiting to load. Then, the instructions are weird, sometimes impossible to actually replicate in the real world. Whoever thought replacing paper instructions for kids toys with this junk ought to be fired. ### 1/5 — Will not work *2023-08-04, version 7.0* won’t work ### 1/5 — DON’T USE *2023-03-30, version 7.0* Instructions make no sense. If you want to make something that’s not in the booklet, use website instead. ### 1/5 — Nothing wrong with the app. *2022-12-06, version 4.9* The app is completely fine and well done but The set I bought being the Levers, linkages & structures was missing a 11 pieces. I wouldn’t recommend buying that set. ### 1/5 — Cool but not quite *2021-01-16, version 4.0* I find the 3D app to be a nice instruction. The key problem is that the instructions are often out of sequence making you remove parts to assemble the next step when it should have been done a couple steps earlier. It's too bad since the education is solid. ### 1/5 — It’s impossible *2020-12-21, version 3.995* I looked and looked and I could not find my kit. I found it in the wrong section and I clicked on it but it was the totally wrong but the kit is very good quality though I think you should just use the pdf ### 1/5 — This is stupid *2020-08-03, version 3.995* Horrible made so hard annoying ### 1/5 — Horrible the worst app ever *2020-02-12, version 3.995* It is the worst app I’ve ever seen the report button doesn’t work and it glitches all the time ### 1/5 — Does not load iPad 2019 *2020-02-03, version 3.995* Just goes to a black screen ?? ### 1/5 — Doesn’t work for me. . . *2020-01-25, version 3.995* Tried to use it for the STEM Greenhouse. The instruction for this don’t include the basic assembly of the greenhouse ; just the optional models!? Even then it keeps crashing. The button for reporting errors / issues with the instruction crashes the app. No use at all. ### 1/5 — The worst present ever *2019-08-04, version 3.994* I wonder if I can give 0 stars? I got this for my 6 year old son, he loves building things and is really clever with stuff like this. But this stuff is super hard to put together. The instructions are very difficult. The blocks are so hard to connect I have to do most of them for him. Plus if they are connected wrong the they are a pain to get apart, even when using their special tool. Once build you can’t really play with it. We did/ I did the crane, while my boy was mainly watching or in tears because he wasn’t able to do it himself, 4 hours later we had a crane that can’t lift anything because it just falls apart. More tears.... I can’t believe how easy this thing falls apart, but yet is sooooo hard to pull apart when you have to. Also the app would freeze then after closing somehow it was showing a different way of putting it together. I’m sorry but this is the worst toy I was ever handed. The amount of tears this thing has caused isn’t funny. ### 1/5 — Pieces missing *2019-01-06, version 3.94* The app is ok but I wouldn’t recommend this game. I just got it for my son's birthday and the first construction we try is short on pieces. ## Most critical reviews (10 lowest-rated) ### 1/5 — Does not work on iPhone *2026-05-31, version 9.7* It’s May 31, 2026 and just downloaded the app but it doesn’t work with iPhones. The app opens but it just shows a wheel spinning but never actually loads. ### 1/5 — Nuke this app now! *2026-05-27, version 9.7* it’s pretty good BUT u only gave me 5 times to use it! like then u made me make a idiotic account in this stinking app. And when I clicked it,it said access denied! Fix this or i sue u! also the instructions it stupidly glitching like crazy and I got i headache because of this trash. If ya fixzit I will rate it 5 stars. ### 1/5 — Incorrect instructions *2026-04-18, version 9.7* Horrible instructions. It’s out of order, having to repeatedly pull apart the model to install a piece that should’ve been placed 5 steps ago. It’s missing steps altogether, and it’s got wrong instructions. Only a lifetime of LEGO and gundam allows you to build it in a reasonable time. ### 1/5 — Does not understand *2026-02-16, version 9.7* Putting a combination that does not fit ### 1/5 — Do not buy *2025-10-20, version 9.7* Instructions for kits are ONLY available through this app, which requires internet access and compulsory registration. Thee is NO OTHER WAY to get instructions - even the “download PDF” button in the app doesn’t work, it just downloads an empty file. This is for a hands-on building kit - the app should never have existed, much less be required for an offline, no-electricity-required toy! ### 1/5 — Trash *2025-01-25, version 9.4* This app is utter garbage. As an engineer with experience with Fusion360, this app is just a waste. LEGO has a much better interface for building their kits. Not only are these CAD drawings/blow ups not complete, the assembly is almost always in the incorrect order that requires you to remove parts just to put another part in the middle. 😡 while building the physics laws sharpening wheel, the completed CAD solution was nowhere near the complete picture on the box. Amazing idea, TERRIBLE implementation. ### 1/5 — These instructions are absolute garbage *2025-01-07, version 9.3* There are no instructions in the box and you are required to use the app. The order of the instructions in the app make no sense and you need to put pieces physically through other pieces, which is impossible. Which is sad since this is a physics product. ### 1/5 — Stuck Authenticating *2025-01-02, version 9.3* After I log in “successfully” it just sits authenticating…its useless ### 1/5 — It’s junk *2024-12-27, version 9.3* It’s totally a piece of junk. Do not install. Seriously. Do not. It is a waste of hard drive space. ### 1/5 — It dosint work *2024-01-30, version 9.0* It dosint work ## Most praised reviews (10 highest-rated) ### 5/5 — I love it I you're haters hate you be not me I love your game I listen to the haters *2025-06-29, version 9.7* I love it ### 5/5 — Easy amazing *2020-11-29, version 3.995* This thing is amazing it actually works ### 5/5 — Bugs fixed, stars added *2019-02-07, version 3.98* I posted a critical review based on bugs that were promptly resolved, so I am updating my review to 5 stars as promised. This is a cool app that replicates in many ways the expensive and trendy LEGO classes that are offered in many cities. The STEM pulley mixer is still missing some critical components. Thanks!! ### 5/5 — Great? *2019-01-06, version 3.94* Great. ### 4/5 — BEST BULID *2025-07-09, version 9.7* The Chinook double blade helicopter I built is amazing. The app itself is awesome because it is 3d enabling you to spin it round while building. I still haven’t explored the app enough but it is wonderful and all the projects are worth the money. ### 4/5 — Great,but needs a little work *2020-12-12, version 3.995* So basically,this has a lot of instructions,but it doesn't have the ORIIGINAL steps from the ORIGINAL kits,so it makes us do impossible steps,but besides that,it's a great app ### 3/5 — Not the best(but the kits are great) *2022-03-15, version 4.5* This is a decent app but needs improvement. The exploded view is great, but the “instructions” are awful! The actual kits themselves are great and I would rate them ⭐️⭐️⭐️⭐️⭐️.I hope that they improve this app in the future. ### 3/5 — The idea is good but manufacturing defects *2021-08-30, version 4.3* The pieces are poorly designed, because in the 3D model some of them are one orientation and in reality they are actually another way, so they don’t fit. Good idea but poor execution and in no way comparable with Lego technic. ### 3/5 — Don’t use these instructions *2020-01-12, version 3.995* You are much better off downloading the pdf instructions from the web site. These are poorly ordered, require pieces to slide through other pieces in impossible ways, and even show pieces floating in space. They have a button to report problems with the instructions, but it causes the app to lock up. The toy itself is great, though. ### 3/5 — Good idea, but needs work. *2015-04-20, version 1.0* I got a chance to use the product today, I loved the idea and can't wait to properly get my hands on it. As for the app the concept is great, however scrolling and zooming is too fast and sensitive. The aspect ratio seems wrong and the models are too small. But hopefully these issues will be sorted down the line. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
