Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.

This eliminates forgotten passwords and ensures a smoother login experience for your users. Beyond authentication, the app allows you to customize registration forms to capture specific business data. You can easily add fields like National ID, Birth Date, and Gender.
Passwords kill conversions. OTP+ swaps them for phone OTP login via SMS or WhatsApp plus one-tap Google and Apple social login. Customer login and signup take seconds: no passwords, no resets, no abandoned carts. Add phone OTP verification at checkout to confirm real shoppers and cut fake orders, RTO and chargebacks on COD.
