Choose the learning job before the app
Evaluate the free version against one real weekly task. If the limit prevents that task, treat the free tier as a demo rather than a long-term solution.
A useful shortlist separates the core learning activity from supporting features. A product can be excellent for one job and still be the wrong centre of a weekly plan.
Build a repeatable week
Choose a session length you can repeat, then assign a clear action to each session. Track completed minutes and meaningful outputs—lessons finished, pages understood, conversations held—not streaks alone.
Use the finder for an initial shortlist and the planners to test whether the time commitment fits your real week before paying for a long term.
What this comparison can and cannot prove
