Both brands are currently testing smart e-cigarette products that require hardware and software to connect via Bluetooth. Currently, RELX has officially launched its smart e-cigarette product, RELX Lingdian, while the MOTI smart e-cigarette Moti S has not yet been officially released.

Bluehole found relevant review regulations regarding tobacco in the App Store review guidelines.

1.4.3 Apps that encourage the consumption of tobacco products, the use of illegal drugs, or excessive alcohol consumption are not allowed in the App Store. Apps that encourage minors to consume any of the above substances will be rejected. Facilitating the sale of marijuana, tobacco, or controlled substances (except for authorized pharmacies) is also not permitted.

It is currently unclear whether the removal of the two apps is related to Apple's review guidelines.
