Our project involves developing a patient-facing iOS app for a medical device company, which means strict HIPAA compliance is non-negotiable. We're looking for iOS App Development Services in Austin that have demonstrated expertise not just in general app development, but specifically in healthcare regulations, secure data handling, and integrating with EHR systems. What specific certifications or past projects should we look for when vetting potential partners? Are there any local firms known for their deep understanding of healthcare data privacy within iOS environments?
