HOW PEOPLE USE IT
Five minutes on the commute. One quiz at lunch. A quick revision pass the night before an interview instead of a panicked scroll through twenty browser tabs. The streak is there to make the habit stick, not to guilt you.
WHY BITE-SIZE WORKS
Spacing beats cramming. Reading one clear explanation a day, then answering a question on it, moves knowledge into the place you can reach under interview pressure. Long articles feel productive and are forgotten by Friday.
FREE AND PREMIUM
Reading is free every day, with a generous daily allowance and three interview deep-dives a day. Premium removes ads and lifts every cap: unlimited deep-dives, bites and quizzes. Try it free for 7 days and cancel anytime in Google Play.
Whether you're preparing for FAANG, a startup, or your first dev job, five minutes a day beats five hours the night before.
