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.

Star Walk 2

  • Its object catalogue is far smaller than SkySafari Pro, so it has little to offer once someone wants to go beyond naked-eye stargazing.
  • It has no telescope control, unlike SkySafari Plus and Pro, so it cannot drive a motorised mount.
  • The free tier carries ads, which some users find intrusive during a stargazing session.
  • It shares a visual style with many similar AR sky map apps, so its differentiation beyond price is limited.
  • Content depth for deep-sky objects and satellite catalogues lags noticeably behind Sky Guide Pro and SkySafari Pro.
