Monk Free Gift with Purchase

While the analytics really leave something to be desired, the ease of use to set up this app, personalize it, stack discounts and features, and create a better customer experience is really all top-notch. The customer service in itself is worth every penny. I've reached out to them multiple times through the chat and have had resolutions and answers well within an hour. They're friendly, quick to respond, and open about what they know needs to improve and their plans for doing so.
If you're looking for a super easy, user-friendly experience to enhance your customer's experience, I would 100% recommend Monk.
