How to make a Standard Fiori application offline

Hi Team,

We have a requirement to make a standard fiori application(e.g. count stock) offline using a platform(and not using indexedDB / sqllite). I did my research and found some ways as below:

1. using smp and offline odata: It involves coding at both frontend and backend side and amount of the code to be inserted depends on the complexity of the standard application involved.

2. Sap Mobile development kit: This platform is available only for android, also i could not find any example or tutorial where it is making a standard Fiori application offline.

Is there any other, Better way we can add offline capabilities to the above said FIORI applications?

Also If this can be done with minimal code infusion to the existing FIORI applications?

Thanks in advance.

Warm Regards,
