No ads. No account required. Just focus. FlowStack is a simple productivity timer, task manager, and routine app designed to beat procrastination and sharpen focus by having a clear name and timer for your task. Use it as a flexible timer for personal, work or study tasks, daily routines, or a focus tool if you struggle with multitasking or constant task switching. FlowStack keeps you on track and making real progress, one task at a time. In FlowStack, each task or to-do has an estimated duration and a timer that starts ticking down when you start the session. This makes it easier starting the task, and helps you get into a flow state by focusing on one task at a time. The current task is also shown as a Live Activity and in the Dynamic Island, making it easy to stay on task even while you're using another app. Once you're done, FlowStack pushes you into the next task. Need more time to finish the first task? Simply add more time to the timer, or continue in a flow state where time is unlimited. If you want to use it as a to-do list rather than focus session, you can also complete a task without starting the timer. Perfect for: • Procrastinators who struggle getting started • People with ADHD seeking simple focus tools • Anyone organizing tasks into daily routines • Users wanting a simple system for recurring tasks • Fans of Pomodoro and Atomic Habits (habit stacking, time blocking) • Professionals and students boosting productivity and focus • Anyone starting good habits—fitness, mental health, cleaning, learning, etc. What makes FlowStack different? • Flexible task timer.

We didn’t just update Clary; we completely reimagined it. We realized that for a productivity app to actually work, it needs to disappear. It shouldn't feel like "using an app"—it should feel like an extension of your brain. So we rebuilt everything—from the UI to the AI—to create the first frictionless planner. Clary is designed for "zero-thinking" capture. You don't fill out forms. You don't manually set dates. You simple speak, type, or snap, and Clary's completely overhauled AI engine understands exactly what you mean, where it goes, and when you should do it. It just works. Clary is different. We believe organizing your life shouldn't feel like a chore. It should feel like a conversation with a brilliant executive assistant who just gets it. Clary is the first task manager designed to be your AI co-pilot, handling the administrative drag so you can focus on what you do best: achieving your goals. WHY CLARY? Most to-do apps feel like data entry. Clary feels like magic. We use advanced AI to handle the tedious parts of planning—sorting, tagging, scheduling, and breaking down tasks—so you can focus on doing the work that matters. CAPTURE ANYTHING, ANYHOW Speak Your Mind: Just say, "Remind me to email the proposal tomorrow morning and follow up next week." Clary understands the context, sets the due date, and prioritizes it for you. Snap Your Notes: Have a messy whiteboard or a handwritten sticky note? Snap a photo. Clary's AI reads it and converts it into a digital checklist instantly. Brain Dump Freely: Overwhelmed? Type a messy paragraph of everything on your mind. Clary will deconstruct it into clear, manageable subtasks and organize them into your projects. MASTER YOUR WORKFLOW Smart Scheduling: Clary doesn't just list tasks; it helps you plan them. Our AI respects your wake-up times and working hours to suggest the best times to get things done. Visual Clarity: Switch between a powerful Kanban board for projects or a standard list for daily agendas. Focus Tools: Built-in Pomodoro timer to help you work in sprints, plus an Eisenhower Matrix to ensure you’re always working on what’s actually important, not just what’s urgent. Gamified Consistency: Build a productivity streak with our "Reflect" system. Track your progress daily and stay motivated. SEAMLESS INTEGRATION Google Calendar Sync: See your events alongside your tasks. Never double-book yourself again. Home Screen Widgets: distinct and beautiful widgets keep your goals front and center. Siri & Shortcuts: Capture tasks completely hands-free while driving or walking. CLARY FREE The perfect starting point for getting organized. Unlimited tasks and notes Standard reminders Up to 2 projects Basic AI capture CLARY PRO Unlock your ultimate productivity potential. Unlimited AI Intelligence: Unlimited voice-to-task, photo-to-task, and brain dump breakdown. Calendar Sync: Real-time 2-way sync with Google Calendar. Unlimited Projects: Organize every aspect of work, home, and side hustles. Advanced Analytics: Deep insights into your productivity trends and streaks. Stop fighting with your planner. Start getting things done. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.tryclary.com/privacy.html
