Possible disadvantages

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • 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
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.
  • Exercise and Physical Activity
    Flexito contains around 200 exercises to pick from. You can select from predefined routines or create your own routines.
  • Free Access
    Flexito does not have accounts or subscription or ads, it's entirely free.

Questions & Answers

As answered by people managing Nullstack and Flexito.fit.

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
