How to Build Your App Stack Without Getting Overwhelmed
The biggest mistake students make is downloading 15 apps and using none effectively. Follow this rule:
The 3-App Rule:
- One flashcard/revision app (Anki or Quizlet)
- One organization app (Notion or OneNote)
- One focus app (Forest or Focus To-Do)
Everything else — mock tests, video lectures, current affairs — can be accessed through a browser. Do not let app management become a form of procrastination.
Frequently Asked Questions
Are paid apps worth it for exam preparation?
For most students, free apps and resources are more than sufficient. The free versions of Anki, Notion, Embibe, Khan Academy, and YouTube channels provide everything you need. Consider paying only for mock test series (Testbook, etc.) specific to your exam, as these provide the most direct value through exam-pattern practice.
Which is better — Anki or Quizlet?
Anki is better for serious, long-term spaced repetition with its superior algorithm. Quizlet is better for quick flashcard creation and casual study. For competitive exam preparation spanning months, Anki is the stronger choice. For board exam revision over weeks, Quizlet is easier to start with.
Can I prepare for exams using only free apps?
Absolutely. Anki (free on desktop and Android), Khan Academy, Notion, YouTube channels, and NCERT textbooks (free PDFs from ncert.nic.in) provide a complete preparation ecosystem at zero cost. Use CalcHub for any calculation needs during practice. Many toppers have cracked exams using only free resources.
How do I avoid getting distracted by apps while studying?
Use apps only for their intended study purpose. Turn off all notifications except your focus timer. Keep study apps on your home screen and move social media apps to a folder on the last page. Better yet, use a tablet for study apps and keep your phone in another room during study sessions.
