How to Choose the Right Framework

Ask yourself:

·        Are we building for iOS, Android, or both?

·        Do we need native performance (e.g., gaming, AR)?

·        Is design flexibility more important than cost?

·        Do we have an in-house dev team with existing skills?

Tip: For many founders estimating the cost to build a mobile app in the UK, hybrid frameworks like Flutter or React Native help reduce time-to-market while keeping quality high, and you can always move to native once you scale.
