different from an ios app design contract, this document will outline the details of your mobile app agreement and will serve as a general consensus on the terms of the project and its completion. below we’ve listed the essential contract elements of a mobile app development agreement, however, you may need to make some adjustments to the contract by adding or removing sections. this is where you include the detailed specifications of the project at hand, what you as the developer promises,and how each step will be handled. here is where you set out the payment structure and fee you’re charging for the services rendered—whether that be a fixed rate or an hourly fee. if it’s the former, it’s essential to lay out exactly what your services include and when the client pays. this is a really important part of your app development contract, it needs to be carefully considered and discussed.
