Wish you could have more time? Now you can! We save people just like you over 1 hour per day using Flexblocks! Flexblocks is an auto-scheduling app designed to optimize your day so you waste less time procrastinating. Here's how it works: When you have something to get done with a start and end date it goes in your calendar, and you're extremely likely to complete it, but tasks that have deadlines like your annoying math homework or physics lab don't, hence they go on to-do lists. The reason your math homework ends up being done right before the deadline is because you brain needs to see time set aside.. Introducing Flexblocks! Flexblocks fixes this problem by instantly scheduling timeblocks for you to complete these tasks before the deadline. Unlike any other apps, we learn what times work best for you to create the perfect schedule everytime! ------------------------------- We would love to hear feedback about the app. If you have any questions or concerns please reach out via any of the channels below: Instagram: @flexblocks Email: admin@flexblocks.app Notes: At present, all of our plans are paid because as a business we need to be able to pay the team to continue adding incredible features to improve your experience. The student plan is discounted significantly to allow all students access to this incredible software. Improvements to the auto-scheduling feature, calendar integrations, and re-occurring events are coming in the VERY near future. Current use at this stage in the development will enable us to bring these features to market much faster.
