Pickup Delivery Date ‑Pickeasy , 599 reviews

If you have a very basic ecommerce model with local delivery, this is probably a great solution for you. If you have more complexity - multiple apps, bundling, discounts... then it may partially function for you. However be aware there are a lot of quirks and limitations. For example they can't account for discounts when calculating a delivery rate, which is a big deal. Support just blames Shopify. Another 'conflicting' app is Bold Variations, which support just blames on Bold... Not able or willing to help fix problems, they just blame other parties - shopify + conflicting apps.
