Mobile App Development Company in Boston

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. Clinical, device-connected and enterprise builds with review-board approval, EHR integration and verification records usually run past 6 months, and we sequence them against your enrolment or semester date. You see working software every two weeks throughout.

No. Appther is remote-first, with its US entity registered in California and the US-facing team working Eastern Time hours for Boston 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, and for device projects we work with shipped units in hand rather than emulators.

Yes. We build patient-reported-outcome and eCOA apps, medical-device companion apps and remote-monitoring products, following IEC 62304 software-lifecycle practices and 21 CFR Part 11 where a study requires electronic records and signatures. We produce requirements traceability, risk analysis inputs, verification records and audit trails as part of the build, work with your regulatory and quality teams on the design history, and test device pairing on production hardware in real homes before enrolment begins.

Yes. Patient-facing, student and consumer apps usually start on Flutter or React Native so one codebase covers both stores on one budget. Products that connect to medical devices, lean on heavy graphics or need platform-specific features go native in Swift or Kotlin. We choose in discovery and write the reasoning into the scope.

We map the regulatory surface with your counsel during discovery and design the app to it. For 201 CMR 17 that means a written information security program, encryption of personal information on the device and in transit, access controls and monitoring, and an incident-response plan that meets Chapter 93H. HIPAA work means role-based access, audit logging and a business associate agreement where the data calls for one. FERPA means student records are accessed only by authorized roles with consent and logging. Each control is documented as it is built, so an auditor or an IRB can trace it.

You do, and it is written into the contract: repositories under your organization, store accounts in your company's name, infrastructure in your own cloud tenancy. An NDA comes before discovery, intellectual property transfers as invoices are paid, and moving the work in-house later is a matter of removing our access.

Go-live opens a hypercare window: crash rates, latency, device-pairing success and store reviews are watched daily and fixed as they surface. After that you select a support tier with a written SLA, OS-update coverage, security patching and a monthly report on adoption and performance, with evidence packs for your next HIPAA or 201 CMR 17 review.
