First, I'd make sure you are very familiar with the requirements for medical- and drug-adjacent apps in iOS. These rules are enforced haphazardly so be prepared to have to justify your app upon submission or updating.
Second, hand-written prescriptions are not much longer for this world so I'd consider the OCR part just a hook to get started and some initial traction - but you'll definitely need to find something sustainable.
> 1.4.2 Drug dosage calculators must come from the drug manufacturer, a hospital, university, health insurance company, pharmacy or other approved entity, or receive approval by the FDA or one of its international counterparts. Given the potential harm to patients, we need to be sure that the app will be supported and updated over the long term.
> 5.1.3 (i) Apps may not use or disclose to third parties data gathered in the health, fitness, and medical research context—including from the Clinical Health Records API, HealthKit API, Motion and Fitness, MovementDisorder APIs, or health-related human subject research—for advertising, marketing, or other use-based data mining purposes other than improving health management, or for the purpose of health research, and then only with permission. Apps may, however, use a user’s health or fitness data to provide a benefit directly to that user (such as a reduced insurance premium), provided that the app is submitted by the entity providing the benefit, and the data is not shared with a third party. You must disclose the specific health data that you are collecting from the device.
