Short answer
Record the class, get a transcript, then one-tap bulleted key points and a concise summary you can study from. Reviewing a summary beats scrubbing through audio when exams are close.
On-device processing keeps recordings private, and there's no per-recording paywall to worry about mid-term.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
