New: You can now focus on a task by clicking it, and drag & drop tasks to reorder! This makes shifting priorities and concentrating on a single task simple and tactile.
We've expanded our analytics into a new "Stats & Analytics" suite that includes the original Productivity Graph plus several new stats cards to give you deeper insights into your habits.
📅 Productivity Graph (Heatmap) — The original calendar-style heatmap (contribution-graph inspired) showing focus density over time.
- My Stats: Total Focus Points, Current Streak, Longest Streak
- 📊 User's Stats Card (Dynamic) — Personalized stats that update when you sign in:
- Total Focus Time
- Completed Sessions
- Most Productive Day
- Total Classic Pomodoros
- Total Reverse Pomodoros
- 🔁 Most Used Pomodoro Card — A small chart showing which Pomodoro type you use most (Classic vs Reverse).
These cards can be shown together on a dashboard or broken into their own section for advanced users.
- 🔄 Auto-save Preferences - Your settings are always remembered
- 🔧 Granular Controls - Customize every aspect of your timer experience
- ⚡ Quick Reset Options - Start fresh anytime with one click
- 🔒 Privacy-First - All data stored locally, no account required
We provide an opt-in sync feature so you can keep streaks and stats consistent across phones, tablets, and computers. Syncing is optional — the app remains fully functional without an account and stores data locally by default.
How it works:
- 1️⃣ Register your email on your PC/Laptop to upload your current stats
- 2️⃣ Sign in with the same email on your iPad/Phone
- 3️⃣ Your data automatically syncs after each session!
We take safety seriously: synchronization is opt-in and secured (data is uploaded only when you register and sign in). By default data stays local; if you opt into sync, we keep your stats synchronized across devices while providing clear controls for disconnecting and removing synced data.

🍅 Classic Pomodoro Timer Features
Classic is the traditional Pomodoro experience reimagined with full customization. It’s perfect when you want strict timeboxing, predictable transitions, and repeatable short work sprints.
- Strengths: predictable flow, great for tasks that benefit from strict timeboxing (coding sprints, study blocks, focused editing).
- Mode behavior: Fixed-length countdown sessions (work, short break, long break).
- Full customization: You can set the Pomodoro, Short Break, and Long Break durations anywhere from 1 minute up to 999 minutes — and save the values as presets.
- Session automation: Auto-start between sessions, configurable session count before a long break, and visual progress indicators.
- Best for: users who prefer regimented sessions, quick resets, and measurable, repeatable progress.
⏱️ Reverse Pomodoro Timer Features
Reverse keeps the same UI, themes, and analytics, but changes the timing model: instead of starting with a preset countdown, it counts your focus time and rewards you with breaks.
- Strengths: excellent for open-ended deep work, creative flow, and for users who resist fixed session lengths.
- Two sub-modes:
- Standard Mode — default behavior with a 1-hour maximum session cap. You can still customize how breaks are awarded (break-tier mapping) and other reward settings; the max cap itself remains fixed in Standard.
- Dynamic Mode — unlocks full flexibility: you can configure the maximum work session up to 6 hours and customize break tiers, making this ideal for longer, uninterrupted deep-work sessions.
- Mode behavior: Stopwatch-style (counts up); breaks are earned based on accumulated time tiers instead of preset countdowns.
- Best for: deep-focus sessions, creative work, and anyone who wants to earn rest based on effort rather than being forced to stop by a timer.
