Wispkin connects you with vetted local caretakers who tend the resting places of the people you love — on the days you can't stand there yourself. Living far from a loved one's grave shouldn't mean it goes untended. Post the cemetery and plot details, and a caretaker nearby offers to help: laying fresh flowers, cleaning the headstone and tidying the plot, or visiting on a recurring schedule you set once. HOW IT WORKS 1. Tell us about the grave — the cemetery, the plot, and a photo so it's found with certainty. 2. Choose your caretaker — vetted people in that town offer their price. Read their reviews and pick the one you trust. 3. See it done — your caretaker sends before-and-after photos of the finished visit. Your card is only charged once you've seen it and approved. WHAT WE TAKE CARE OF • Fresh flowers laid on the date you choose — a birthday, an anniversary, an ordinary Tuesday. • Gentle cleaning of the headstone and the plot around it, so the name reads clearly again. • Recurring care — weekly, monthly, or quarterly visits that continue on their own. WHY WISPKIN • Every caretaker is reviewed before their first visit. • Photo proof with every completed visit. • Pay on approval — your card is authorized when you book and only charged once you approve the finished work. Become a caretaker: you already know the cemeteries in your town. Set your own prices and service area, and get paid for every visit you finish — Wispkin handles the payment. Wispkin is a marketplace intermediary. Care is performed by independent caretakers, not by Wispkin. Payments are processed by Stripe; Wispkin never takes custody of funds.
