Ratings and Reviews



hi there..
it’s very easy to use program, I love it 😎
but previous design was better, if possible add hour and minute ...🙏

Developer Response ,

Thank you for your comment.
When creating the swift version, we excluded "hour", "minute", and "hour minute" from the time combinations. But I found that some needed it.
We will consider it as an additional item for the next version upgrade.
