GrindSession

GrindSession is a focus timer that helps you work in deep, distraction-free blocks - then reflect on how each one went and watch your focus habit build over time.

Start a timer, do the work, and when it ends jot down how focused you felt. Every session is saved locally, so your history and stats are always yours - no account, no cloud, fully offline.

Highlights

1. Focus timer - pick 15, 25, or 50 minutes (or a custom length), then start, pause, resume, or stop.
2. Set your intention - name what you are focusing on before you start; it stays on screen while you work and pre-fills your reflection.
3. Daily focus goal - set a target for the day and watch a progress bar fill as you rack up sessions.
4. Menu-bar countdown - the remaining time lives in your menu bar, so you stay on track without the window open.
5. Breathing warm-up - a short, skippable breathing exercise settles you before each session begins.
6. Post-session reflection - rate your focus 1-5, pick a mood, tag the project, and add a note about what you worked on.
7. Session history - every session grouped by day, with time, duration, focus level, and your notes.
8. Productivity analytics - total focus time, your daily streak, average focus, peak hour, a 7-day chart, a colourful activity heatmap, and a by-project breakdown.
9. Session-end notifications - a gentle native notification when a block finishes.
10. Keyboard-first - start a session, pause, stop, and save your reflection without touching the mouse. A built-in shortcuts panel keeps every key one click away.
11. Light and dark - a clean native macOS design that follows your system appearance automatically.
12. Local-first and offline - everything is stored on your Mac in a plain SQLite database. No account required.

How it works

Open GrindSession, choose how long you want to focus, and hit start. A calm breathing warm-up eases you in, then the countdown runs - in the window and in your menu bar. When time is up you get a notification and a quick reflection prompt to capture how it went.

Over days and weeks the History and Stats tabs turn those sessions into a picture of your focus habit - your streak, your best hours, and how much deep work you are actually getting done. Everything stays on your Mac - no account, no cloud, fully offline.

Perfect for

1. Deep work - writers, developers, and designers who work in focused blocks.
2. Pomodoro fans - anyone who runs 25-minute sprints and wants them logged automatically.
3. Habit builders - people who want a daily focus streak and honest stats to keep momentum.
4. Reflective workers - anyone who likes to note how each session felt and spot their patterns.
