Given Instinctive Notes works with your patients medical data, privacy and security are critical in deciding how the service is delivered.
The Android operating system simply is not secure enough for Instinctive Notes to be confident that patient medical data would be protected. There are too many exploits and malware, even in the official Play Store, that could compromise an Android device and therefore compromise patient privacy.
If the situation changes we may consider a native Android app, but there are no current plans to do so.
