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.

Verdict

The call

The clearest difference is review sentiment: Flexblocks at 100% against Formalize's 25%. Flexblocks also leads on price (Free vs $1.99) and update cadence (every 10 days vs every 9 months). Formalize's advantage is rating (2.6 vs 1.0) and in-app purchases (none vs 3). On device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Formalize holds the better App Store score, 2.6 against 1.0. That said, the two scores are not equally well evidenced: Formalize has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Formalize's written reviews are positive against 100% of Flexblocks's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Formalize ships an update every 9 months, Flexblocks every 10 days. The most recent releases landed on September 14, 2026 and June 7, 2026 respectively.
