Details can be improved
Works as advertised and is reliable working in the back ground which is awesome . (1) It’s very loud, would be great if there was an option to change the volume in app rather than relying only on the overall volume in iOS. (2) Further, would be neat if one could chose system sounds too or upload my own. People sometimes look at me strange when this very loud church bell suddenly rings from my pocket. A more subtile “ding” like an incoming message would be less conspicuous in that kind of situation. If the developer implements these two things I would pay 1€ for it, no question. Especially, if it keeps working reliable “like clockwork”.
