With Appmaker, you can easily turn your Shopify store into an app: it automatically synchronizes with your data and recreates all the details (menu, product info, etc.). You can create both Android and iOs apps. 

Appmaker - Mobile App Builder includes all the popular features for a mobile app, including push notifications, and also provides you with analytics to learn how users interact with the app.

Appmaker offers a free plan: you can create an app for free but you won’t be able to use push notifications or integrate product reviews. You’ll also pay a 2% fee on each order made via the app.

Paid plans are Basic, Growth, and Scale: they cost $99, $249, and $999 respectively. They differ in the number of supported integrations and the level of support: in Growth, you’ll get an implementation specialist to assist you, and in Scale, you’ll have a dedicated success manager and custom app support.
