3 brilliant free, open-source (FOSS) apps students should try this weekend (Aug 14–16)

Published Aug 14, 2026, 12:45 PM EDT Dibakar Ghosh is a tech journalist at How-To Geek, where he focuses on Linux, Windows, and productivity tools. His goal is simple—help readers at every skill level get more done with the tech they use every day. He began his writing career in 2016 with WordPress tutorials, later moving into digital marketing, where he spent years reviewing complex tools for marketers. His work has also appeared on Authority Hacker, where he’s shared in-depth guides on digital workflows and online productivity. That experience now shapes his journalism, blending analytical depth with practical, real-world advice. When he’s not writing or testing software, Dibakar is usually watching movies or playing video games. He’s a huge Christopher Nolan fan and a strong proponent of the theater experience. In gaming, he has sunk hundreds of hours into Insomniac’s Spider-Man series, Returnal, Prototype, Darksiders, and Final Fantasy titles. Being a student is hard. You have to manage and organize piles of notes and study materials, somehow keep it all in your head, and on top of that juggle classes, assignments, and chores that never seem to let up. And so, to help you out, here are three brilliant free and open-source apps that can take some of that pressure off your shoulders and make student life a little easier. Anki Turn boring studying into a game of remembering Anki is a flashcard app built around two ideas: active recall and spaced repetition. Instead of re-reading your notes over and over, hoping they stick, you turn them into flashcards—a question on one side, the answer on the other—and quiz yourself from time to time. The sessions are short, so you can knock one out in five minutes here and there, and before you know it, the things you kept forgetting start sticking. What makes Anki stand out from other flashcard apps is how it asks you questions. After answering a question, Anki lets you rate how difficult you found it to recall the answer. If you find it hard, that card shows up more often. If it was easy, it shows up less often. This way, Anki keeps surfacing the information you tend to forget or mess up, and through repeated exposure, helps ensure it sticks in your long-term memory. I personally think Anki is a surprisingly good alternative to doomscrolling. It's primarily a desktop app, but it's available on smartphones too, and you can sync your decks across devices. So instead of reaching for reels during those idle five-minute gaps in your day, you can run through a deck and sharpen your knowledge. Anki is cross-platform and available for Windows, macOS, Linux, and Android, though the official iOS app (AnkiMobile) is a paid app. Habitica Turn your student life into an RPG Habitica is a gamified habit tracker that turns your real-life tasks and habits into a role-playing game (RPG). You get a character that you can level up and customize with gear that you unlock as you complete more tasks. It also has a health bar, and failing to complete tasks costs you health points. Losing all your health will cause your character to die. The app lets you create three types of tasks: Habits, Dailies, and To-Dos. Habits are things you want to do regularly, often multiple times a day. This can be things like drinking more water throughout the day or reading before going to bed. You can create good habits and bad habits. Doing a good habit gives you XP or Gold, whereas doing a bad habit costs you health points. Dailies are recurring tasks you do once a day or on specific days. These can be workouts, group study sessions, or journaling. Missing them will cost your character health points. To-Dos are one-off tasks like buying a gift or donating to charity. They don't deal damage if you miss them, but if you ignore them for too long, they will turn red. Completing an old, red task earns you bigger rewards. This encourages a better-late-than-never attitude and incentivizes you to complete a task you set out to do, even if you're doing it late. You can set a reminder, ideally at the end of your school day, to open Habitica and check out everything you accomplished and what you missed. This lets you track your progress and see where you need to improve. However, the thing that I like about it most is the social layer. You can form a party with your friends and take on quests together. During a quest, everyone needs to complete their Dailies because if one person slacks off, the whole party takes damage. This way, you're no longer just letting yourself down when you skip your revision—you're letting your entire party down. That adds a layer of social accountability that's hard to replicate with a solo to-do app. Habitica is primarily a mobile app, but you can also use the web app to access it from your desktop. Paperless-ngx Stop worrying about where you saved that PDF Credit: Paperless-ngx Paperless-ngx is a document management system that you can use to store and retrieve all your study material—PDFs, research papers, notes, scanned handouts, and other academic material you've collected for your courses. It then uses OCR to extract text from your documents and makes them searchable by their contents, not just their filenames. Say you have a “Semester 1 Mathematics” PDF with a chapter on eigenvalues somewhere inside it. In a traditional file manager, searching for “eigenvalue” might get you nowhere if the term isn't in the filename. However, in Paperless-ngx, that search can pull up the document instantly because it has extracted and indexed the actual text inside it. There's also an optional AI layer built into Paperless-ngx that takes document search a step further. It allows you to use semantic search to find documents based on their meaning rather than exact keywords. This means you don't necessarily have to remember the specific terms used in a document—simply describing what you're looking for can surface the relevant documents. To power these AI features, you can either use a local LLM backend such as Ollama if you want to keep everything on your own machine or connect to a hosted AI service instead, like Claude or ChatGPT. Paperless-ngx is a self-hosted app. You can find information on how to get it up and running on its GitHub page. Your student life just got a lot easier Habitica should help you stay on track with the habits you're trying to build, Paperless-ngx should save you from ever having to think about file organization again, and Anki should drill those difficult concepts into your head through repeated quizzes instead of mindlessly re-reading your notes. Back in my day, these kinds of apps simply didn't exist, and honestly, we just struggled through it. But they exist now, and if you aren't using them, you're falling behind the students who are.
