Shared effort, not pressure
Saktus brings the practical parts of studying into one place — planning what to do, testing what you know, focusing on a session, and keeping up with friends who are working towards their own goals.
A study system only helps when you can actually use it. Saktus keeps the core tools close together so you can move from planning a session to doing the work.
Recall the answer. Don’t just recognise the page.
Use flashcards to test what you remember, spot gaps in your understanding, and organise revision around the topics you need to learn.
Give one task a clear start and finish.
Use Pomodoro-style sessions to work in manageable blocks, with breaks between them. Keep your attention on the task in front of you.
Make your study day easier to follow.
Organise study blocks around the day ahead, keep your priorities visible, and know what you intend to work on next.
Add study blocks to your day and decide what deserves your attention.
Use flashcards to test yourself and share useful decks with friends when you want to study together.
Start a timer and give the task in front of you a dedicated block of time.
See the study time friends have chosen to share and use it as a nudge to return to your own plan.
Your own routine. Your friends beside you. One place to study.
Flashcards put your memory to work. Test what you know, notice what needs another look, and build decks around the subjects and topics you’re studying. When deck sharing is available, learn from the material your friends have prepared too.
How does an action potential initiate across a neuronal cell membrane?
Your study time tells one part of the story. See your own focus time alongside friends who choose to share theirs, and use that visibility to encourage one another to keep showing up.
No shame for a quiet day. No claim that the longest timer means the best learning. The point is to make effort visible and studying feel a little less solitary.
Saktus is free to use. The study tools and social features described here are part of one student-focused experience — not a maze of plans or a trial that expires.
No credit card required to start
No expiring free trial period
No paid study-tool paywalls
Saktus began as FlowState Productivity with a straightforward idea: make it easier to plan study time and follow through. It is being built around real student routines — preparing for assessments, keeping track of subjects, practising what you know, and finding a little momentum alongside friends.
The name has changed to Saktus. The reason for building it has not.
The Saktus mobile app is in development. For now, you can start with the web experience.

In active testing
Make a plan, choose a topic, start a focus session, or invite a friend into your study routine. Saktus is free to use.
Bring your friends into the routine.
Make studying a shared effort. Connect with friends, exchange useful flashcard decks, and compare study time to see how everyone is showing up. Keep the focus on the work — and help one another stay consistent.
Study alongside friends
Know who you’re studying with and make individual study sessions feel less isolated. Saktus should support a sense of shared momentum without turning every session into a public performance.
Share flashcards
Pass useful decks between friends instead of rebuilding the same revision material from scratch. Shared cards should make it easier to learn from one another’s preparation.
See the time you put in
Compare study time over a clearly defined period, such as a day or week, with friends who have chosen to share their activity. Use the comparison as encouragement, not as a judgement of who is the better student.
