Log the thorough examination, the next date sets itself, and Cowstail reminds you before anything lapses.

Open the item and tap Log inspection. Set the date, the result (pass, monitor or fail), the inspector's name and any notes. Save, and the next due date is set from the item's interval.
In date is fine. Due soon is inside the last 30 days before the next examination. Overdue means the item should not be on the rope until it is examined. Home shows the due-soon items so you see them without opening Kit.
Due-soon items appear on Home, and Cowstail reminds you before they lapse by email, and by push when notifications are on. The six-month clock never depends on you remembering.
Pass sets the next date. Monitor records wear that is within limits but worth another look. Fail is recorded against the item so the history shows it should not go back on the rope until it has been examined again or replaced.
The item's inspection history is the record a supervisor or client asks for: date, result, inspector. Keep the serial numbers right and the history speaks for itself.
