Mobile App Development Company in Atlanta

A focused MVP takes 8 to 14 weeks from kickoff to store submission. A mid-scale product with a custom backend and third-party integrations takes 3 to 6 months. Payments and enterprise builds with processor certification, security reviews and multiple user roles usually run past 6 months, and we sequence them around your bank partner's and processor's timelines. You see working software on a real device every two weeks.

No. Appther is remote-first, with its US entity registered in California and the US-facing team working Eastern Time hours for Atlanta clients, so stand-ups, demos and escalations fall inside your working day. A named senior engineer is your single point of contact from kickoff to launch.

Yes. We design for PCI DSS 4.0 from the first screen: card data is tokenized at the point of entry with your processor or gateway, the app and backend are kept out of scope wherever possible, logging never sees a card number, and every transaction carries an audit trail. We build idempotent payment flows and a reconciled ledger, handle Regulation E error resolution, and prepare the documentation your QSA and bank partner will work from. The assessment and any licensing remain with you; our job is to make them straightforward.

Yes. Consumer, merchant and marketplace apps usually start on Flutter or React Native so one codebase covers both stores on one budget. Products that depend on payment hardware, heavy graphics or platform-specific features go native in Swift or Kotlin. The choice is made in discovery and written into the scope.

We work through the regulatory surface with your counsel in discovery and build the app to it. HIPAA work means encryption, role-based access, audit logging and a business associate agreement where the data calls for one. GLBA means safeguards for financial data and documented vendor controls. Georgia's breach-notification law means an incident-response plan that meets the notice clock, tested before it is needed. Controls are documented as they are built so an assessor can follow them.

You do, entirely: repositories under your organization, store accounts in your company's name, infrastructure in your own cloud tenancy. We sign an NDA before discovery, assign intellectual property as each invoice clears, and if the work ever moves in-house the handover is a matter of revoking our access.

After go-live we run hypercare, checking crash rates, payment failures, latency and store reviews daily and fixing what surfaces. Then you pick a support tier with a written SLA, OS-update coverage, security patching and a monthly report on retention and performance, with a capacity review before holiday volume.
