Looking for a way to add a time selector without date

I am trying to create a medication timer app and am looking for a component to be able to add a specific time for someone to take a dose of medication. I am also looking for a way to select a time duration between doses. Example: Select a starting time to take a medication (07:00 am) and then I need to have a selection for the duration between doses (4:00 hours).

Any suggestions would be greatly appreciated.

Hi @salexander71 ,

There would need a collection that store time and fraction, this can be shown on list on modal screen.

fraction store number that will be added to date, it is calculated down to minutes.
