Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
eBird
- It does not identify birds for you, so a beginner needs Merlin or field guide knowledge alongside it.
- Data quality depends on volunteer regional review, so unusual sightings can take time to verify or may be rejected.
- The interface is built for structured data entry rather than casual browsing, which some users find less inviting than a photo-first app.
- Hotspot and rare bird alert usefulness varies heavily by region, since it depends on local birder density submitting checklists.
- As a research tool first, some workflows such as trip list exports and taxonomy changes prioritise data accuracy over ease of use.
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.
