Reclaim your focus

You can use Karter across all your devices. Download the app on iPhone or Android, or open getkarter.com in any desktop browser, and your plan and progress follow you. You start by answering a few questions about your focus and your goal, and Karter builds your personal plan. Each day you do a short guided practice of three exercises that train your attention. When it's time to work or study, start a Pomodoro or a focus session with background sounds. Karter measures it all: your focus time day by day and your exercise results, compared with your first day, so you can see your focus change. Karter isn't just another focus timer. It's designed to help you train focus like a skill and see it grow day by day.

Most apps solve only one piece of focus. Blockers keep outside distractions away. Mindfulness apps help you calm down. Timers track your focus time, but only in a few fixed modes. Used together, they don't connect: your practice stays inconsistent, and features that have nothing to do with focus get in the way. That's why they rarely work.

Karter is built around one goal: improving your focus. That goal shapes your personal plan, your tools, your analytics and everything we add next.

Karter has two parts: a daily practice that trains your focus, and tools that help you use it.

The daily practice

• Breath: slow, guided breathing while you count each inhale. It calms you down and shows how long your attention stays put.
• Reflect: one thoughtful question to stay with until the timer ends. When your mind wanders, tap “I drifted” and come back. Every return is a rep.
• Anchor: watch a calm orb and tap only when it ripples. It builds steady attention and the patience to wait for the right moment.

The focus tools

• Pomodoro: classic work and break cycles for tasks you keep putting off.
• Focus session: 45 minutes of focus and a 5 minute break by default, adjustable up to 90 minutes for deep work.
• Sounds: natural sounds, like rain, waves or a stream, close to brown noise and tuned to help your brain get into focus mode.

Each exercise is built on a method studied in attention research: breath counting, noticing when your mind wanders, and sustained attention tasks. You can see the studies in How the protocol works. The studies tested those methods, not the Karter app.

Yes, Karter is built to work around your schedule. The practice is short enough to do on a lunch break. The focus timer fits into the work or study you already do, so you're not adding hours, you're getting more out of them. Pick a time that suits you and Karter reminds you. Miss a day and nothing is lost: there are no streaks to break, you simply continue tomorrow.

Karter gives you daily practice and shows how your results change compared with your first day, so you can see it for yourself. It isn't a medical treatment or a diagnosis.

Karter sits between three kinds of apps you may already know:

• Website blockers stop distractions while they run. Karter trains your attention, so it holds up even when nothing is blocked.
• Meditation apps help you relax. Karter uses breathing as a first step, then trains attention and helps you use it at work.
• Brain games make you better at the game. Karter trains focus directly and shows how it changes on your real work.

If you've tried blockers or meditation and still find it hard to stay on one thing, Karter is made for you.
