Appstle Loyalty Reward Program

This is a very robust app with all the loyalty features we needed, and at a very reasonable price. Visual customization of the widget isn't as easy as with some others, but they allow access to a CSS panel and HTML injection, which, if you're a little savvy, give more control than the competition. Probably the best part of working with Appstle is their 24/7 support team, and it truly is 24/7. Occasionally something needs to be escalated, but even then they always get back to you within a day or so. Easy 5/5 stars.
