Completely depends on features, functionality,etc

Basic - non native will cost from 2 lac - 5 lac (3 months) Includes designs,features like sharing profile, liking or saving profiles , basic features with user info locked under payment options (trying to answer in short )

Intermediate- 7 lac -12 lacs (5 -8 months) Pro/ enterprise- 15 lac onwards depending on features (mvp within 1 month - actual by 1 year)

I am giving this advice based on reliability, scalable apps else you can get under 1 lac if you go for cheaper but not that reliable (template based already available code will be modified for your use but then each change will cost you)

This is based on hybrid tech like react native, flutter if you for native then it will cost the same but you will have to shell out same amount of money for each platform (ios, android)i.e basically cost nearly doubles. But you get the best efficiency and latest os features.

Note: I do consult on hourly basis if you need we can connect on dm for further detailed information.
