There are two or three hours in most days when studying is impossible but listening is not. Commuting, the gym, cooking, walking somewhere.
Studyflash fills exactly those hours: point it at a deck and it produces an episode. It is not a text-to-speech reading of your slides. It walks through the key concepts in order, so it functions as revision rather than as noise you stop hearing after four minutes.
The transcript stays in sync
Read along while it plays, click any line to jump the audio there, or search the transcript when you are somewhere you cannot use audio at all. On mobile, playback continues when you lock the screen or switch apps.
What it is good for, and what it is not
Hearing material in different words reinforces what you have already studied, and it is genuinely useful for the second and third pass over a topic.
It is not active recall, and listening will not do what the flashcards do. Use it for the dead time rather than instead of the deck.
