While we all know Canva and how easy it is to create social media posts and images through their web app, they also offer a super-simple mobile app to help you create Stories.
You can choose through numerous layouts and templates based on your brand's aesthetics, like Vintage, and theme-based, like Valentine's Day and Holidays.
Our favorite templates are Black & White and Digitalism. Of course, this is totally subjective to our aesthetics. We're sure you'll find another style that fits to your brand.
If you have a Canva account and use their web app, you can login and sync the designs from web to mobile.
