Money grab
Literally nothing to offer other than a glorified speed tracker, that cashes in on its name implying it has some use for train fans. All it does it show you speed. To keep track of max speed achieved you need to pay a subscription!!! That's the first screen that shows when you launch tbh, 'pay us'. Also the map it has (of train lines around the world allegedly) is unusable as the moment you try and zoom out a bit it zooms you back in to your position. If you want a speed tracker, there's a Speedometer app in the store and it's free. Don't let this Densha Otaku app fool you that it offers anything else for true densha otaku. Such a waste of a good name, and for that as well you should be ashamed.
