Mobile App Development Company in Seattle

A focused MVP is in both stores 8 to 14 weeks after kickoff. A mid-scale product with a custom backend and third-party integrations takes 3 to 6 months. Enterprise and clinical builds with security reviews, multiple roles and legacy integrations usually run past 6 months, and we sequence them against your peak season or pilot date. A new build lands in your hands every two weeks regardless.

No. Appther is remote-first, with its US entity registered in California and the US-facing team working Pacific Time hours, 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, which is more continuity than most agencies offer once the contract is signed.

If the app collects anything that could be linked to a person's health, fitness, sleep, reproductive care, biometrics or visits to a care facility, it very likely does, even if HIPAA does not. The act requires separate consent to collect and to share, a dedicated health-data privacy policy, deletion rights and a ban on geofencing near care facilities, and it carries a private right of action. We map every health-adjacent data flow in discovery with your counsel and design the consent and deletion experiences to the statute.

Yes. Consumer, retail and B2B companion apps usually start on Flutter or React Native so one codebase covers both stores on one budget. Products that lean on hardware, heavy graphics, background processing or platform-specific features go native in Swift or Kotlin. We decide during discovery and record the reasoning in the scope.

Compliance is mapped with your counsel in discovery and engineered into the product. HIPAA work means encrypted storage, role-based access, audit logging and a business associate agreement where the data calls for one, layered under Washington's health-data law rather than replacing it. Biometric enrolment follows the state statute: notice and consent first, no sale, published retention. For payments we keep card data out of your systems with tokenized checkout. Controls are documented as they are built, so an auditor can retrace them.

You do, without exception: repositories under your organization, store accounts in your company's name, infrastructure in a cloud account you control. An NDA is signed before discovery, intellectual property transfers with each payment, and bringing the work in-house later is a matter of removing our access.

Launch is followed by hypercare: crash rates, latency and store reviews are watched daily and fixed as they surface. Then you choose a support tier with a written SLA, OS-update coverage, security patching and a monthly report on retention and performance, with a scaling review before holiday peak or any launch you expect to trend.
