Strikingly specializes in creating one page websites, which means all the different sections are on the same page and you can scroll between them. The templates are very well done and work great on all resolutions. Speaking of which, you can use the iOS or Android apps to update your website on the go or just check the analytics.
There is a blog section with all the standard features included and a very basic contact form.
There is a free plan available which allows for unlimited websites, 5GB bandwidth and even a "store" where you can sell one product per site. You won't be able to sell digital products through the store though.
For $8/month you'll get 50GB bandwidth, a free domain and 5 products per store.
I would recommend Strikingly if you want great looking one-page websites that are not very information-heavy.
