Your current app is unmaintained and keeps getting rejected by the stores.

FAQs
Mobile App Development questions
How much does an app cost to build?
A cross-platform MVP with auth, a core feature set and payments usually sits between £2,700 and £7,500. Larger products with custom backends go beyond that. We give a fixed price per phase.
Native or cross-platform?
For 9 out of 10 business apps, cross-platform is the right call — one codebase, one team, both stores. We recommend native only when you need heavy device hardware access or 120fps graphics.
Who owns the code?
You do, in full, from day one. It lives in your repository and your app store accounts, and we hand over everything at the end of each phase.
