FAQ

Common questions about app development in Mumbai.

How much does app development cost?
App development starts at ₹2,50,000 for a cross-platform React Native app (8-day sprint). Native iOS or Android starts at the same price. Full SaaS with web + mobile from ₹4,50,000. All GST-inclusive; UPI and Razorpay EMI accepted.
How long does it take to build an app?
We deliver a cross-platform app MVP in 8–10 days. A full SaaS product with web + mobile takes 10–14 days. We run daily Loom walkthroughs so you always know progress.
Android or iOS — which should I build first?
For most Indian businesses, Android first is the right call — it covers 95%+ of the Indian smartphone market. We recommend React Native so you get both platforms from one codebase cost-effectively.
Will you publish our app to the Play Store and App Store?
Yes. App Store and Play Store submission is included in all app development plans. We handle all certification, screenshots, descriptions, and any rejections until your app is live.
Do I own the app source code?
100% ownership. We hand over the complete source code via GitHub on delivery. All accounts — Google Play Console, Apple Developer, Firebase — are transferred to you. We lock nothing.
