This is a very fun app to play on my iPad when I want to play my custom StepMania charts on the go. There are a few problems, though not as bad as this one: offline play. Playing offline for long enough causes the game to lag when playing a hard song or simply spamming the buttons. If this problem would ever be fixed, I will gladly change my rating to 5-star. Aside from that specific problem, I love this app!

Over all this ddr game is pretty good but some songs need more than 2 notes simultaneously to play and thats kinda awkward playing on the phone and i dont have a controller that connects to my phone to fix this the option to change where the buttons are is nice but i can't find one that i can play comfortably with 4 fingers.

While looking for a way to play simfiles on the road, I found this. It works pretty well, although there are a few bugs that need to be fixed or a few design improvements. First, importing custom songs through a website works, but it can be a bit clunky at times. It would be great if we could also manage simfiles through the Files app, because there's been a time where a zip file would be imported incorrectly and caused the game to crash on startup, forcing me to reinstall the game. Second, adjusting the offset is a little weird because the value doesn't use the millisecond format that is seen in most other rhythm games. This means that I've tried to change the offset to 100ms and it ended up being a lot higher than that, which would make the notes appear 2 minutes after they were supposed to and I was unable to change it back. This also required a reinstallation. The other issues I have are just small nitpicks and polishes: song previews can sometimes overlap each other or skip like a CD, adding a pause button would be useful, tapping a lane causes the next note in that lane to disappear even if that note is really far away, shock notes aren't implemented, a no-fail mode would be nice, and the app causes my phone to quickly heat up. This is still a great simfile player and I would recommend this to anyone looking for a DDR phone app, but fixing these small problems would make the app even better than it already is.
