The Tapcart app is the mobile version of the Shopify app.
We do not provide an "out-of-the-box" integration to connect Algolia to TapCart. If you have access to the code, it should be possible to add Algolia to your application, but will require some development work.
TapCart did launch a connector with Algolia in their marketplace. This integration has been built by Tapcart, we can not provide support for Tapcart with Algolia connector as this was built by an external vendor, and support requirements should be directed to the developer of the connector.
