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.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Alеrtly sells 3 in-app purchases, starting at $5.99 per 7 days and FlowStack sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
FlowStack holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: Alеrtly has 82 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 9% of Alеrtly's written reviews are positive against 100% of FlowStack's.
Alеrtly ships an update every 4 months, FlowStack every 5 days. The most recent releases landed on June 1, 2026 and September 8, 2026 respectively.
