The honest truth

Your phone was
built to beat you.

Infinite feeds. Perfectly-timed notifications. Algorithms that know you better than you know yourself. Willpower alone was never a fair fight — so Stratum changes the rules.

Stratum app blocking settings

App Blocking

Silence the noise.
The moment you start.

The instant your session begins, Stratum locks every app that would steal your attention. The wall goes up automatically — no willpower required.

  • TikTok, Instagram, YouTube — all blocked
  • Activates the moment your timer starts
  • Works natively with iOS Screen Time
  • Choose exactly which apps to silence

Focus Timer

Every minute,
where it matters.

Your to-do list and your timer together in one session. Every second is automatically tagged to the right subject — your stats build themselves as you go.

  • Pomodoro or countdown — your choice
  • Linked to tasks and subjects automatically
  • Vertical drain bar shows time remaining at a glance
  • Pause and resume without losing your streak

  • Urgent, approaching, and safe — colour-coded instantly
  • Progress bars show how far through each task you are
  • Calendar view for the full semester picture
  • Everything in one place, not scattered across four apps

At-a-glance breakdowns of your study hours by subject, day, and week. Streaks, totals, and trends — all built automatically while you work.

  • Hours per subject, tracked without lifting a finger
  • Weekly bar chart with daily breakdown
  • Streak counter to build consistent habits

Student reviews

Built by a student.
Trusted by students.

★★★★★

"Finally deleted my old screen time app. Stratum actually blocks things instead of just showing me charts after I've already wasted the afternoon."

Emma T. — UNSW, Law
★★★★★

"The deadline view alone is worth it. I can see exactly what's due and when, colour-coded by urgency. My anxiety around assignments dropped massively."

James L. — USYD, Engineering
★★★★★

"Love that it tracks my hours by subject without me doing anything. The stats just build up as I go. It makes me actually want to keep going."

Priya M. — Monash, Commerce
★★★★★

"I've tried every study app out there. Stratum is the only one that felt like it was designed for a student, not a productivity influencer."

Ryan K. — UQ, Medicine
★★★★★

"The blocking is real. Instagram literally won't open during a session. That one feature changed how I study more than anything else I've tried."

Sophie A. — Melbourne, Arts
★★★★★

"Calm, clean, no fluff. Other apps feel like they were built to impress you. Stratum just quietly helps you study. That's a huge difference."

Lachlan B. — ANU, Science

Common questions

Questions answered.

Yes — Stratum is free to download and free to start. Core features including the timer, app blocking, and deadline tracker.
You can block any app on your iPhone through iOS Screen Time. Popular choices are TikTok, Instagram, YouTube, Snapchat, and X but the choice is entirely yours. Stratum activates the block automatically when your session starts and removes it when you finish.
Stratum is currently available on iOS only. Android support is on the roadmap — follow along for updates.
When you start a session, you select a subject — for example, LAWS2014, Chemistry, or Maths. Stratum automatically attributes every minute of that session to that subject. Over time, your stats screen builds a full breakdown. No manual logging, ever.
All your data — tasks, deadlines, session history — is stored securely. We don't share your personal study data with third parties. See our privacy policy for full details.
Apple's Screen Time shows you what happened after the fact. Stratum makes something happen in the moment. It uses Screen Time's blocking capability as an engine, then layers a full student workflow on top — timers, tasks, deadlines, and stats built specifically for how students actually work.
