Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Seek by iNaturalist

  • Identification quality depends on how well iNaturalist community data covers a given region, so obscure or under-photographed species can be misidentified.
  • It lacks the deep plant care guidance that commercial apps like PictureThis provide, since it is an identification tool, not a gardening assistant.
  • Observations made in Seek are not automatically added to the iNaturalist research database unless separately uploaded, which surprises some users expecting automatic contribution.
  • The offline model download is a meaningful app size, which matters on devices with limited storage.
  • Because there are no accounts, there is no cross-device sync of identification history.

Udemy

  • Course quality varies significantly as Udemy allows anyone to create and sell courses without vetting
  • No formal credentials or degrees offered, unlike Coursera and edX which offer institution-branded certificates
  • Courses are self-paced with no instructor interaction or support, making structured learning difficult for some students
