Study with flashcards scheduled by the SM-2 spaced-repetition algorithm, the same approach Anki uses: cards you find hard come back sooner, cards you know come back later. Everything runs offline on your own device, which makes it usable on a commute with no signal.
How to study with spaced repetition
Make a deck and add cards — a prompt on one side, the answer on the other.
Review the cards the scheduler puts in front of you today.
Rate each card honestly. That rating is what decides when you see it again.
Come back tomorrow. The scheduler builds the next session from your ratings.

Questions
What scheduling algorithm does it use?
SM-2, the spaced-repetition algorithm behind Anki. Intervals grow for cards you answer well and shrink for cards you do not.
Does it work offline?
Yes. Cards and scheduling live on your device, so a review session needs no connection at all.
