Timeframe: A simple MVP may take 3–4 months, while a full-featured app could take 9–12 months.
When planning your budget, it’s important to consider the Cost to Hire App Developer, as this can significantly impact your overall development plan.
Step 9: Post-Launch Support and Updates
Launching your app is just the beginning. To retain users, you’ll need to:
Release regular updates with new features.
Fix bugs and improve performance.
Gather user feedback and optimize accordingly.
