Do more in less time with 25-minute blocks. Take it one block at a time and surprise yourself with how much you can accomplish. Inspired by tried and trusted time management techniques. Block & Flow is simple, beautiful and will get your productivity flowing. FEATURES: - A 25-minute visual countdown keeps you focussed and avoiding distractions. - Manage your energy levels with regular breaks - Measure your day, week and longer by how many blocks you finish. - Colour code a block for the activities that you do often or care particularly about. - Goals enable you to be intentional with your time. - History gives you an understanding of where your time goes. - A block’s duration can be changed to your ideal time. WHY IT WORKS: - It makes it easy to get the day started. Just do your first block. - Creates an enjoyment and satisfaction as you see all that you get done. See your blocks build up one by one. - It is clear when to stop. Stop when your block has finished, or after you have done x many blocks for the day. - Every block that you finish is a small success. As these small successes build-up, your self- belief grows. - If you keep finishing your blocks. The time will add up to a lot and you will surprise yourself. (We under-estimate what we can do in the long term). WHO IS IT FOR? People tell me that they do x many blocks a day, or over a week which is fantastic. A few people have been completing their blocks for a year and more. I imagine someone completing their blocks over a month, a year and ultimately many years. I believe they will grow as a person, stretch themselves, and be surprised with what they are able to learn, create and accomplish. This is what excites me and motivates me to do my best for someone that chooses Block & Flow. What will you accomplish, one block at a time?

Verdict
The clearest difference is in-app purchases: Countdown Timer Nano at none against Block & Flow's 3. Countdown Timer Nano also leads on iOS requirement (15.0 vs 17.6). Block & Flow's advantage is rating (3.9 vs 3.5) and update cadence (every 3 weeks vs every 3 months). On price, review sentiment, ads and device support there is nothing between them.
