Is there any way we can add a delete button in Appsheet form just as in-built save and cancel button. I wanted to add a functionality where the user can delete a record if the metric displayed on the form doesn’t suits our output?
A cancel on a new record’s form is as good as delete as the form and the record will not be saved if the user taps cancel.
Also you could add valid_if expression in the fields to ensure that if for example the metric does not suit whatever output you are expecting. A field value outside valid_if expression’s allowed values will not let the user save the form even accidentally and she/he will need to cancel the form, unless the user fills in the valid values.

Also please note that there is no delete record option in the form view because in case of form view for adding a new record, the record is not yet added till save is committed. For existing records, the form view helps in “editing” of a record.
So delete operation ( or action to be precise in AppSheet terminology) is available in summary ( table, deck, gallery, card )views or detail view.
