I keep a spreadsheet of every productivity app I have installed since my second year at Waseda. It currently has 61 rows. Each row has an install date, an uninstall date if there is one, and a one-line autopsy. Most autopsies say some version of the same thing: “duplicated something I already had” or “spent more time configuring than using.” I mention the spreadsheet up front because it is the reason you should trust — or at least calibrate — what follows. Most “best app” lists are paid placements wearing a costume. You can tell because every description glows, the same ten apps appear on every list, and the author somehow has affiliate links to all of them. I have no affiliate links, no advertising relationships, and a documented history of uninstalling things I was excited about three weeks earlier. Some of the most-promoted “student apps” are missing from this post entirely, and that is deliberate. I will get to them at the end.
Notes, and the argument I keep having with myself about them
The app I have kept longest is Obsidian, free for personal use, and it is the best free note-taking tool available in 2026. It stores plain markdown files locally on your machine and lets you link notes to each other, which over time produces something people call a knowledge graph and I call “the folder that finally replaced my seventh paper notebook.” There are seven notebooks on the shelf above my desk in Setagaya, all full, all nearly unsearchable, and the day I accepted that grep beats flipping pages was the day Obsidian won. The learning curve is real — my first vault was a mess of orphaned notes for about two months — but the payoff compounds. If you are doing thesis work, long research projects, or anything you will still care about in three years, this is the one. The paid tier is only their sync service; I sync my vault through Git for free, and Dropbox or iCloud work fine if Git sounds like homework.
Notion is the tool I recommend to people who look at Obsidian and visibly deflate. It bundles notes, databases, project tracking, and wikis into one polished interface. It is heavier, and your data lives on their servers rather than your disk, which bothers me more than it will bother most people. But for someone who wants one place for class notes, an assignment tracker, and a reading log, it works, and the free tier in 2026 includes unlimited blocks for personal use. Group workspaces have limits, though small project teams fit under them — the shared workspace is genuinely good for group projects, which I say through gritted teeth as someone who left his Waseda study group because we lost forty-plus minutes per session to social drift. The tool was never the problem there.
If both of those sound like more machinery than you want, Standard Notes is free, open source, encrypted, and deliberately simple. I keep my journal in it. Nothing about it will impress anyone, which is roughly the point.
The flashcard hill I will die on
Anki is free on desktop and Android, a one-time $25 on iOS, and it is the single highest-return app on my spreadsheet. It implements spaced repetition — the SM-2 algorithm classically, or the newer FSRS — and I have used it daily since my algorithms course at Waseda, where I took Cornell notes on paper and then converted the cue column into cards every Sunday. That pipeline got me through exams that flattened people smarter than me. The desktop interface is ugly and dated; the mobile apps are nicer; none of that matters, because the algorithm is the product. Do not be seduced by prettier flashcard apps with worse scheduling. We have a full Anki guide if you want the deep version — med students and language learners live inside this thing for good reason.
RemNote is the one alternative I take seriously. It merges note-taking with spaced repetition: you mark parts of your notes and it generates the cards. Less mature than Anki, more elegant, and a reasonable choice if maintaining two separate systems is the thing that would make you quit both. I tested it for a semester-length experiment in 2023 and went back to Anki, but I logged it as a close call, not a failure.
Keeping myself off my phone, with mixed results
Forest is free on the web and about $2 on mobile. You plant a virtual tree, and if you open your phone before the timer ends, the tree dies. When I first read that description I laughed, then I installed it, then I discovered that my brain apparently assigns real moral weight to a cartoon tree. It works better than it has any right to. The free web version with the browser extension is identical to the mobile app, which is rare honesty in this market.
Cold Turkey is what I escalate to during crunch periods. It blocks the sites and apps you specify for a set time, and in some configurations you literally cannot disable it without restarting your computer. The free version covers blocking; advanced features are paid. This is the external commitment device for people — me, some weeks — who cannot be trusted around Reddit and YouTube during focus hours.
For the timer itself, Pomofocus is a free web app, no account, opens and starts counting. I ran my pomodoro logs through three fancier timers before concluding that the fancy ones added nothing but settings screens. If you want the technique rather than the tool, our Pomodoro guide covers it.
Calendars, tasks, and the boring backbone
Google Calendar is free and is the default for a reason: it syncs everywhere, integrates with everything, and has never once broken on me in a decade. My entire scheduling method is treating study blocks like meetings I would be embarrassed to miss. Use it even if everything else in your stack is different.
Two smaller calendar tools earn their place. Cal.com and Calendly both have free tiers and replace the email tag of scheduling study group sessions or office hours — you send a link, they pick a slot. And Reclaim.ai, also with a free tier, is an AI scheduler that looks at your calendar, finds the gaps, and fills them from your task list. I was skeptical, tested it for six weeks, and kept it; if your schedule is chaotic enough that finding time is itself the problem, it earns its keep.
For tasks, Todoist is the best free manager I have used across every platform. The natural-language input is the killer detail — typing “submit essay tomorrow at 5pm” creates the task with the right date, and the free tier handles unlimited personal tasks. TickTick is the close competitor, with a built-in pomodoro timer and habit tracker and a more generous free tier; if you want tasks, timer, and habits in one binary, pick it instead. Sunsama deserves an honest footnote: it is the best daily-planning app I have tried, it forces you to time-block every task, and at roughly $20 a month I could not justify it as a student and still wince at it now. Paid only. Mentioned for completeness, not recommendation.
Research, writing, and the apps that saved my citations
Zotero, free and open source, is the standard academic reference manager, and the hours it saves are almost embarrassing to quantify. It grabs citations from any web page, organizes them, and generates bibliographies inside Word or Google Docs. I resisted it for one full term and formatted a 40-source bibliography by hand, once, as a control condition. Never again. If you write more than a few papers a year, install it today.
Pocket, free, saves articles for later and strips them down to a clean reading view synced across devices — my train reading between Setagaya and Shibuya runs through it. Readwise is paid, around $8 a month, and I include it anyway because it is the closest thing I have found to a personal knowledge OS: it aggregates highlights from Kindle, Pocket, and papers into a daily review and feeds Anki and Notion. Voracious readers should at least know it exists.
On the writing side: Grammarly’s free tier covers spelling, grammar, and basic style, and it is meaningfully better than the checkers built into Word or Docs — especially if English is not your first language, which for me it is not. Hemingway Editor, a free web app, highlights bloated sentences and passive voice; I run drafts through it when clarity is being graded. LanguageTool is the free, open-source, privacy-focused alternative that works in 25+ languages, for anyone writing outside English or uncomfortable with Grammarly reading their text.
For quick reference, three sites I treat as infrastructure: Wolfram Alpha handles most STEM computation free (the step-by-step feature is paid, but the bare answer is usually enough to retrace your own reasoning), Symbolab is the free-with-ads solver that shows more work for calculus and linear algebra, and Khan Academy remains the best free education on the internet when your textbook’s explanation of a topic simply does not land.
Sound, files, and the long-tail utilities
I would be a strange person to omit the site you are reading. Lofi Study 24/7 — our continuous stream plus free wallpapers — is the audio-visual layer of my own setup, and there is actual research on why ambient music helps. Noisli, free with ads, layers custom ambient sounds — rain, café, brown noise — and pairs well with the stream if you want lofi under rain. Brain.fm is paid-only music engineered for focus; some of its research claims hold up, some are marketing, and the free trial is the correct way to find out which category your brain falls into.
Files: Google Drive gives you 15GB free and is the default for assignment backups and group docs. Dropbox syncs more reliably but only gives 2GB free. MEGA offers 20GB free with end-to-end encryption, which is where my sensitive research data goes. For distraction-free drafting, FocusWriter is free and open source, Cold Turkey Writer locks you in until you hit a word count — brutal, effective — and iA Writer is a $30 one-time purchase that I paid happily but you do not need to.
What I would install on a clean machine
When a kohai asks me to set up their laptop, the kit is eight items: Anki for the daily fifteen-minute review, Obsidian or Notion for notes (pick one, commit), Google Calendar for time blocking, Todoist for tasks, Zotero once essays start, Forest or Cold Turkey for enforcement weeks, free Grammarly, and a bookmark to our stream. Then I make them promise not to install anything else for three weeks. The trap with productivity apps — I have the spreadsheet to prove it — is switching tools as a substitute for doing the work.
The skip list, from my own autopsy notes: Roam Research (paid, overcomplicated, Obsidian does it free), most “AI study buddy” apps (they do work you should be doing, and get facts wrong), subscription habit trackers (the free tiers were always enough), dedicated mind-mapping apps (paper won every test I ran), and paid video-course platforms when Khan Academy, MIT OpenCourseWare, and freeCodeCamp cover the material free.
The pattern in my 61 rows is unambiguous: the value came from the five to seven tools I used consistently for years, not from anything new. Anki paid off around month six, not week one. My Obsidian vault became a second brain after a year. Consistency compounds; novelty just resets the clock. For the study system these tools plug into, see study techniques that pair with lofi and building a daily routine.
