Comparison
InstantPWA vs Smile.io
Loyalty points program, or the install prompt that makes repeat visits easier?
Smile.io runs points, VIP tiers and referral rewards for e-commerce stores. InstantPWA has nothing to do with loyalty mechanics — it simply gets your store installed on the home screen so returning is one tap, which can complement a loyalty program rather than replace it.

When to pick which
Use Smile.io if you need a rewards/points program to drive repeat purchases. Use InstantPWA when you want to reduce the friction of coming back at all — home screen icon plus optional push — regardless of whether you run a loyalty program.
