Identification applications are real-time and more portable identification tools than DNA Barcoding, and they are applied widely in our daily life. DNA barcoding use sections of rbcL genes extracted from chloroplasts to distinguish species , while apps use taxonomy as their principle and AI technology as a tool. We formed a hypothesis that the APPs are more focused on better catering domestic plants, making them not adequate for cases especially scientific species identification while DNA barcoding will be more accurate but also more expensive.
