Frequently asked questions
How much does an app cost?
Simple apps start from the price on our pricing page. Apps with multiple user types (for example customer, vendor and delivery partner) cost more; we share a fixed quote after understanding your features.
Do I need both Android and iOS?
Many Indian businesses start with Android only. With Flutter, adding iOS later is quick and affordable.
