Doesn't support HOTP Doesn't work with otpauth:// URLs--a must. Manual HOTP entry appears broken as well. Import via camera shows the image upside down (Nexus 6  LMY48I). Camera import appears to succeed  but HOTP scans are still misinterpreted as TOTP. For reference  Yubico Authenticator works where FreeOTP fails and the ZXing scanner works correctly.
