  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving

Questions & Answers

As answered by people managing Flexito.fit and Nullstack.

What makes your product unique?

Flexito.fit's answer

  • Flexito is entirely free without ads or subscriptions.
  • You do not need an account. Open it and start stretching. There's no sign-up and no login.
  • It works offline. It's an installable web app (PWA). After the first visit, all routines and their exercise images work without a connection.
  • It runs anywhere. It works in any modern browser on phone, tablet or desktop, and you can add it to your home screen like a native app.

Why should a person choose your product over its competitors?

Flexito.fit's answer

Because it's a free alternative to all other payed and freemium apps in this space.

Apps like Bend are good, but most of their routines sit behind a monthly subscription. Flexito gives you the same kind of guided daily stretching for free.

How would you describe the primary audience of your product?

Flexito.fit's answer

  • People who sit at a desk all day and want to undo stiff necks, backs and hips
  • Beginners building a daily stretching or mobility habit
  • Runners, lifters and other active people looking for quick warm-ups and cool-downs
  • Anyone who has tried a stretching app and stopped at the paywall

What's the story behind your product?

Flexito.fit's answer

As many of you out there, I sit too much in my chair during the day and I'm trying to stretch more often and strengthen my back/core muscles.

There are a lot of "free" apps out there e.g. Bend or DownDog that are helpful but I was annoyed with ads and limitations where you can only do a single routine once a day etc. So I built Flexito as a free and open alternative.

Which are the primary technologies used for building your product?

Flexito.fit's answer

Flexito is built on Angular and it runs entirely in your browser.

Who are some of the biggest customers of your product?

Flexito.fit's answer

  • Everyone who stretches daily
