Best Study Group Apps for Students: 14 Picks by Job

The best study group apps for students cover six jobs between meetings: chat, scheduling, shared files, flashcards, task tracking and reading together. Most groups need only the first three in week one: a group chat, a scheduling poll and one shared folder. Add the others when a job starts slipping.

We make StudyDuo, one of the 14 apps below. We hold it to the same two questions as the rest: what it does for a group, and what it doesn't. If you're still looking for people, that's a different search. Compare apps that pair you with a study partner, join a public Discord study server, or start with classmates in your own course.

The 14 apps at a glance

We read each company's own pages on November 13, 2026, and every number in the table comes from them. Free plans change, so open the link before you plan a term around one.

A group chat people actually read

Pick the chat your members already open every day; a tidier app that nobody checks loses.

GroupMe

GroupMe is Microsoft's free group messaging app for iPhone, Android and the desktop browser. A group can hold 5,000 members, but Microsoft's help page warns that groups over 200 get noisy: GroupMe works as reply-all, so every answer notifies everyone.

• Good at: one chat for a whole class, at no cost.
• Falls short: in a big group, a study question sinks under everything else.

WhatsApp

WhatsApp raised groups to 1,024 people and added in-chat polls in November 2022. Its Communities put related groups under one umbrella, with an announcement group that reaches every member at once.

• Good at: a course with one announcement group for dates and a smaller group per topic.
• Falls short: files sink in the stream, so keep them in the folder below.

Slack

Slack sorts talk into channels, so #exam-dates stays quiet while #questions is busy. On the free plan, messages are searchable for 90 days, and anything in a free workspace older than a year is deleted for good (pricing).

• Good at: a separate thread for each subject.
• Falls short: a 15-week term lasts 105 days, so by finals the first two weeks are out of reach unless someone pays.

Study group apps that find a time for everyone

All three polls below are free to start.

When2meet

When2meet calls itself "a free survey tool". You create an event from the home page without signing up, over specific dates or days of the week. One catch: for days-of-the-week events, it expects all participants to be in one time zone. A group spread across zones should poll specific dates instead.

Rallly

Rallly lets people vote in the browser without an account. Each slot converts to the voter's own time zone unless the organizer locks one, and every option gets a yes, if need be, or no. The free plan takes votes on three polls at a time, or one without an account. It deletes a poll 30 days after its last date if nothing happens (pricing).

Doodle

Doodle now has organizers sign up for a free account before a poll goes out; voters still don't need one. A free poll can offer 20 time slots, and free users share the link from their own email. Hidden polls, deadlines and automatic reminders need Doodle Professional.

When every name is on one slot

Seeing other people's answers changes your own. James Zou, Reshef Meir and David Parkes analyzed every Doodle poll created in the US from July to September 2011 (CSCW 2015). In 345,297 open polls, where voters saw earlier answers, people marked 53% of slots as available. In 7,390 hidden polls, they marked 39%.

The extra yeses went to slots that were already very popular or very unpopular. The authors' reading: voters want to look flexible, and an unpopular slot rarely wins, so agreeing to it costs little. Poll creators picked open or hidden themselves, so this is a pattern, not proof. Before you book, ask who'd rather not; in Rallly, "if need be" says it for them.

One folder for notes and past papers

Google Drive

Each Google Account includes 15 GB of storage, shared across Gmail, Drive and Google Photos. With link sharing on, anyone with the link can open a file without signing in, and one file can go to 600 email addresses (sharing help).

• Good at: one folder for slides, past papers and the group's summary.
• Falls short: once a member's Gmail and photos fill those 15 GB, Drive blocks most of what they do except downloading and deleting.

Microsoft OneNote

OneNote is free on every supported platform. A shared notebook has to live in OneDrive or SharePoint, and a free Microsoft account comes with 5 GB of OneDrive. Microsoft's sharing guide covers Windows, Mac, iOS and the web, and says you can't share a notebook from Android.

• Good at: one notebook with a section per chapter, for groups on Microsoft accounts.
• Falls short: a link to one section opens the entire notebook, so keep private notes in a notebook of their own.

Flashcard decks the group shares

Quizlet and Anki have their own write-ups: Quizlet among apps for studying with friends, and Anki in a medical school group. Two more free options:

Knowt

Knowt offers learn mode, spaced repetition and practice tests for free, and imports Quizlet sets. People you share a set with can study it but not edit it (sharing help), and a password option is free for students. The paid Ultra plan removes ads, at $7.99 a month billed yearly (plans).

Brainscape

Brainscape keeps creating, sharing and studying your own cards free, including cards others share with you and control over who can edit. Making a class private takes Pro, listed at $7.99 a month, so on the free plan your group's cards aren't private.

What the research says about shared decks

Studying someone else's deck is already the norm. In a survey published in Memory in 2022, Inez Zung, Megan Imundo and Steven Pan asked 901 undergraduates at a large US university how they use flashcards. The 701 who used digital flashcards said where their premade sets came from, and they could pick more than one answer:

These students used premade sets 56% of the time, and that's where study group apps can quietly cost you learning. Steven Pan and four colleagues ran six experiments with 284 undergraduates (Journal of Applied Research in Memory and Cognition, 2023). Each student spent equal time with cards they filled in themselves and with premade ones. Two days later, self-made cards produced better recall (d = 0.45) and, in most experiments, better answers to application questions (d = 0.29). Paraphrasing and copy-and-paste both helped; retyping a definition word for word didn't.

So split the chapters, but keep writing your own cards for your weakest topics, even when a classmate's deck covers them. The authors note that editing someone else's cards hasn't been tested.

How you review matters too. Megan Imundo, Inez Zung, Mary Whatley and Steven Pan ran three experiments with 698 undergraduates (Metacognition and Learning, 2024). Students practiced vocabulary on paper flashcards, alone or with a partner, and learned about the same amount either way. In the first two experiments, though, students working alone predicted test scores about 20 percentage points above what they got, while pairs predicted accurately. Solo students told to answer out loud were as accurate as the pairs. Between meetings, say your answers aloud; at meetings, quiz each other.

A board that shows who does what

Praveen Aggarwal and Connie O'Brien studied group projects in marketing courses in 2008 (Journal of Marketing Education). Social loafing, doing less when your share blends into the group's, grew with the scope of the project and the size of the group. Several rounds of peer evaluation during the project reduced it. A board builds both into a study group's week: small cards with one name each, checked at every meeting.

Trello

Trello is free for up to 10 collaborators and 10 boards per Workspace, with unlimited cards and files up to 10 MB. Three lists cover most groups: This week, Doing and Done, with a due date on every card.

• Good at: seeing at a glance whose card hasn't moved.
• Falls short: an 11th member means paying, from $5 per user a month on yearly billing.

Todoist

Todoist is free for five personal projects with up to five people each, 5 MB uploads and one week of activity history. That fits a small group that mostly needs names and due dates.

Asana's free Personal plan is built "for one or two people" and has two seats (pricing), so it suits a pair rather than a group.

Reading and annotating together

Social annotation puts the group's highlights and questions on the text itself, next to the line they're about.

Hypothesis

Hypothesis includes private groups in its free tier. Only members see what's written in a private group, and people join through an invite link (private groups). For a PDF saved on your computer, notes sync across copies of the same file by its "fingerprint". The group can email one PDF around and still read each other's comments. That works only on a laptop or desktop, in Chrome with the extension, and scanned pages need selectable text (saved PDFs).

Perusall suggests study groups set up a book or journal club course. On courses created after July 6, 2026, each student pays a platform fee of $5 to $25, set by the instructor. The instructor, the department or the school can cover it for the whole class instead (pricing). A course can get a waiver in cases such as first-time use. Use it if your instructor already does.

Kelly Miller and three colleagues tracked 79 students in a flipped physics course at Harvard who read and annotated in Perusall before class (Frontiers in Education, 2018). Of them, 95% completed all but a couple of the reading assignments. Across the course, students averaged 13.3 annotations per assignment. The number of sittings a student read in predicted exam scores; the number of annotations didn't.

Two limits: the annotations were graded, which a study group's aren't, and the authors co-founded Perusall. The data show a link, not a cause. The habit worth copying is opening the text more than once before you meet.

A set time to study on camera

StudyDuo, ours, adds a seventh job: the solo hours between meetings, spent at the same time on camera, with no host and no link to send. Study Hour begins once a day at one shared moment, shown in each member's local time, and lasts an hour with no break. Focus Room never closes. Follow your groupmates, and the app tells you when one of them starts studying.

It won't replace the apps above: StudyDuo has no group chat for a private group, no shared files, no flashcards and no shared task board. Mics are off in both rooms, so talking a problem through needs a call elsewhere. You can message one person at a time; a 1:1 session adds a mic and chat for two people with verified photos. Free accounts get an hour in the video rooms each day, and Premium, free for a new account's first 14 days, lifts that cap. More on the room itself: an online study group that's always running.

Starter stacks by group type

Which study group apps you need depends on the group: three friends on one campus can skip what a group spread across time zones relies on. Start with the row closest to yours.

Once the tools are set, the meetings need content: 20 activities for a study group, plus a host's playbook for calls when you meet online. For the call itself, see the boards and quiz games to open during a session.
