What’s the best approach for developing a customer loyalty app with rewards, points, and user engagement features?

Hi everyone,

I’m planning to develop a customer loyalty app that helps businesses reward their customers through points, cashback, and exclusive offers. The goal is to improve customer retention and engagement while giving users an easy way to track their rewards.

I’m currently in the planning stage and would appreciate advice on a few things:

What’s the best tech stack for building a loyalty app (mobile + web dashboard)?

How can I securely store and manage loyalty points to prevent fraud or manipulation?

What are some must-have features for a modern loyalty system (QR codes, referral programs, gamification, etc.)?

Are there any recommended third-party APIs or SDKs for reward management or customer analytics?

Should I consider blockchain-based loyalty systems, or is a traditional database sufficient?

If you’ve developed or worked on a loyalty or rewards app before, I’d love to hear what worked well (and what to avoid).

Thanks in advance for your insights! 🙌
