You can get in touch with our bespoke web app development agency in case you feel the need to get maximum performance from the app or find out what the bottlenecks for the product are. App maintenance services include the modifications of your app if needed after it is launched. Apart from that, the list of maintenance services includes upgrades, adding new features upon request, adding new ones if required. A maintenance agreement is not the thing of first importance when it comes to product development, and we do understand that. So in case, there’s no such an agreement yet, feel free to get in touch with us.
