Grest job jeminie ### 4/5 — Rediscovering this app! *2026-07-10, version 2.0.5* This is great, i used to play bve on my old pc, good to see a way to play this is back. Where are you supposed to put the bve routes you download though? ### 3/5 — It is important to add back the permission for us to add Hmmsim2-based addons *2026-06-16, version 2.0.2* I am writing for expressing my concerns regarding the latest update for Hmmsim Legacy. It is observed that ONLY Addons written in OpenBVE format can be imported as an Addon. However, my workshop has been developing some addons that are written in the Hmmsim 2 format (those including scenarios and AI train), as we have spent countless hours reverse engineered the addon format that you have created. I hereby hope that one can allow users to add Hmmsim 2-based addons to Hmmsim Legacy, to increase the flexibility, as well as allowing some profound projects to float back to the surface again. ### 4/5 — 재밌는 흠심레거시 *2026-06-09* 제가 흠심레거시를 플래이 해보면서 진짜 잘만들셨고 특히 안내방송,환승음악이 조금 아쉬워요 안내방송 이랑 환승음악을 바꾸신다면 별 5개 줄수 있을거 같습니다! 별 4개 정도 드릴게요!~ ### 4/5 — リアルになったけど *2026-06-07* 空とか影とかのグラフィックが綺麗になっていいと思いますが、その分バッテリーの減りが早くなります.. 仕方ないですけどね あと、スマホだけで路線追加できるようになったのは助かりますがやり方が分かりません！！ 公式さん！教えてください！ I think it's good that the graphics of the sky and shadows are beautiful, but the battery will decrease faster.. I can't help it though Also, it's helpful to be able to add routes with just a smartphone, but I don't know how to do it!! Official! Please tell me! ### 3/5 — Addons *2026-06-04, version 2.0.2* Its not working with bve or hmmsim addons. Lot of textures are not load and everything is empty space ### 3/5 — It became not good add ons when updated *2026-06-02, version 2.0.1* How can I still use the wold version the new version makes the addons worse ### 5/5 — An incredible return *2026-05-31, version 2.0.1* I first got this game shortly after it released, when I was still a young teen with my first iPad Mini. Back then it was my favourite game to play, and I recently got it again on my iPhone 16 Pro without any loss in enjoyment. To see this app suddenly get its first revamp in 10 years brings me joy. Thank you. ### 5/5 — 드디어 업데이트..!! *2026-05-31* 업데이트 해주셔서 정말 감사합니다.. 최고에요 쨩!! ### 4/5 — 레거시 업데이트 *2026-05-31* 이번 업데이트 너무 좋은데 옛날 버전에서 쓰던 열차들을 사용하면 튕기는게 많네요 5점 주고싶은데 튕기는거 고치면 좋겠어요 ### 5/5 — 有空， *2026-05-31, version 1.2.7* 他自己去：有 ### 4/5 — 제작자는 노선추가를 안하고 관리도 하지않는 거이 방치상태 입니다 *2026-05-23, version 1.2.7* ㅠㅠㅠ ### 5/5 — 안녕하세요 *2026-03-21* I’m korean using japanese Apple ID, so I can’t speak japanese. This game is the best mobile train simulator. ### 4/5 — 흠심1하고 좋아서 돈주고 깔았는데 *2026-02-14, version 1.2.7* 새로운 노선 추가하는게 많이 복잡하긴 해도 노선 추가만 하면 잘 구동되서 좋네요 ### 4/5 — Could do with a line 7 extension to seongam *2026-01-15, version 1.2.7* Could do with a line 7 extension last cheongdam to seongham ### 4/5 — 無料にした方がいいかも *2026-01-08* このゲームは神ゲーです。路線追加分かりませんけど楽しいです！いい点ゲームオーバーない100キロだせるやりやすい　　　　　　　　　期待通り変わらなくて良かった ### 4/5 — 열차추가 *2025-11-26, version 1.2.7* 열차가 더 있으면 좋을 탠대 배포 분은 또 안대요 추가하면 1점+ ## Most critical reviews (10 lowest-rated) ### 1/5 — Don’t buy. *2026-08-02, version 2.0.5* This game, no matter what, crashes. Even when I set every graphics setting to the lowest, it never loads up any route. Reloaded and tried again millions of times, same result. Stuck on the menu eternally. If I could give 0 stars I would, there’s nothing here. It IS a scam ### 1/5 — This sucks *2026-06-12, version 2.0.2* At this point, just bring back the old hmmsim 2. Keep the remake as another app but with a different train as the picture. Hmmsim 2 should’ve gotten an update where you can import routes in apple files like how this remake got. My trains doors are the only thing along with the wheels that load in this remake ### 1/5 — Startet nach Update nicht mehr *2026-06-01* Das Spiel startet nach dem Update auf dem MacBook Air M3 nicht mehr! ### 1/5 — 개쓰레기어플 *2024-12-08* 돈받고 팔았으면 업데이트 하는 성의라도 보여야 되는거 아니냐? 사후지원은 눈꼽만큼도 없는데 옹호하는 애들 진짜 이해안간다. 제발 업데이트 좀 해라 양심없는 사람아 ### 1/5 — 노선이 너무 없음 *2024-07-01, version 1.2.7* 아니 노선이 두 개 있는게 말이되요!!!!??? 아니 빨리 업데이트 좀 해주세요!! 그리고 1,2,3,4,5,6,7,8,9호선이 다있어야지 이중에 2,7호선만 있으면 어떻합니까? 2호선 신차랑 7호선 신차랑 다른호선 빨리 늘려서 업데이트 해주세요!!!!!!!!!!! ### 1/5 — iOS는 어떻게하라는거지? *2023-09-03, version 1.2.7* 아니 노선을 다운받는건 알겠는데 제작자 채널에서 공식으로 알려줘야지 다른사람들이 알려주면 안드로이드만 다알고 iOS는 어케하라는겨? 아는사람도 있지만 그래도 노선 만들기 싫으면 이거라도 알려주던가 ### 1/5 — Mettez des add-ons directement sur l’app store *2022-08-12* Bon jeu avec des graphismes de qualités,mais s’il vous plaît, mettez plus de lignes parce que c’est compliqué d’en mettre sur IOS faites une mise à jour avec plus de lignes !!! ### 1/5 — Not worth the time *2021-12-25, version 1.2.7* Have downloaded this multiple times not just on old last iPhone but now today with brand new Iphone 13 I’ve tried deleting / reinstalling the app & still not got anywhere from doing it…. Absolute waste of time, effort & money. Don’t recommend this at all ### 1/5 — 頼む！ *2021-08-08, version 1.2.7* 人追加してくれ！！！！！！！！ ### 1/5 — 開けない *2021-04-11, version 1.2.7* アプリを 開こうとしたら、アプリが落ちる 何度もやっても落ちる これが1年も続いてるし 謝罪も無いしアップデートも無いし 酷い ## Most praised reviews (10 highest-rated) ### 5/5 — The game has been transformed *2026-07-19, version 2.0.5* This app is essentially the gateway to open BVE for mobile, thanks for the new legacy update. Highly recommend ultra high-quality graphics.. ### 5/5 — 유저분들 공지(2.0.3업뎃) *2026-06-18* 님들 이번주 업뎃있어요 그 애니매이션 출입문 스도 정광판 정차위치 모니터 적용 돠요 ### 5/5 — 사운드문제 *2026-06-11* 에드온으로 받은 노선을 플레이하면 가속 또는 제동시 구동음이 이어지지 않습니다. 예를들어 가속시에 가속 구동음이 나다가 중간중간 감속음이 나는 식으로 말이죠. 에드온으러 추가한 건 다 그런거 같습니다 동일 에드온을 Open bve에서플레이 할때는 괜찮으나 hmmsim 에서만 그런현상이 발생하네요 ### 5/5 — Update ideas! *2026-06-11, version 2.0.2* I love the return of one of the train apps EVER. BUT THERE’S TWO THINGS I ACTUALLY WANTED TO SEE IN THIS APP! The first one, is a new train line added to this game instead of an add-on! The second one, is a passenger cam I actually want to see the POV of one of the passengers in the station and/or in the Train! ### 5/5 — 10년만의 업데이트 *2026-06-07, version 2.0.2* 퀄리티가 대폭 상승했네여 게임할 맛 나네요 ### 5/5 — 드디어 *2026-06-06* 게임엔진의 한계로 더이상 업데이트가 진행되지 못했던 흠심2가 업데이트 되어 정말 기쁩니다. 어릴때 BVE와 흠심메트로를 즐겨했던 유저로써 흠심2의 화려한 복귀는 언제나 환영입니다 ㅎㅎ ### 5/5 — 업데이트라니! *2026-06-04* 정말 옛날에 설치해두고 오래동안 안하다가 했더니 폰에 안맞더라구요 그래도 좋다 싶었는데 업데이트 해주셔서 좋습니다ㅎ 더 발전된 모습 기대하겠습니다! ### 5/5 — 最高 *2026-06-03* 今回のアップデートでiPhoneだけでできるようになったんで神です。ただ、UIは前に戻して欲しい… ### 5/5 — 레거시 업뎃 *2026-06-02, version 2.0.1* 와 퀄이 개쩐다! 개발자님, 최적화 문제 고쳐주세요! 그거빼면 완벽해요! ### 5/5 — 와!!! 드디어 업데이트 되었네요 *2026-06-01* 최고의 어플입니다 감사합니다~!!!^^ --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
