Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Memrise
- The free tier caps daily reviews tightly enough that consistent vocabulary building in practice requires the Pro subscription.
- Memrise phased out much of its earlier community-created course library in favour of official courses, so learners who relied on community decks for less common languages lost access to that content.
- It teaches vocabulary and set phrases well but offers comparatively thin grammar instruction, so it works best as a companion to a grammar-focused course rather than a standalone method.
- Language coverage for the flagship Learn with Locals video feature and speaking practice is uneven, concentrated in a handful of popular languages.
- Unlike Anki, the spaced repetition algorithm and content are closed and cannot be customised or exported, so a learner cannot take their review data to another tool.
Sky Guide
- It is iOS-only, unlike SkySafari which also covers Android and desktop.
- It has moved from one-time purchase to a subscription model, and long-time users who paid once for earlier versions have criticised the change publicly.
- Pro tier pricing is high relative to Star Walk 2 for broadly similar core stargazing functionality.
- It has no telescope control, unlike SkySafari Plus and Pro, which limits it to naked-eye and camera-based observing.
- Its relationship to other apps under the same distribution platform is not clearly documented, which makes long-term support commitments harder to assess.
