Some may think only a 'techie' in the office or a self-proclaimed 'expert' on Facebook can develop a Guestbook without a hitch.


Others look for low-cost alternative Guestbook apps from overseas or open source Guestbook apps that claim to have what they're looking for.

CASE STUDY: POWR put Rbia Shades on the success track

Rbia Shades needed to expand beyond its region by bringing its products online. They needed a low-maintenance, non-techie solution.


After much research, they chose POWR as their no-code tool of choice.

Rbia started to see success with POWR Popup almost immediately, adding over 600 new contacts in the first 90 days.


They then realized that there was a complete suite of other solutions they could use to improve their online experience for site visitors.


Soon, Rbia embedded an Instagram Feed app on their website and noticed site visitors who interacted with the app doubled the time spent on their page while growing their followers to over 11k on Insta at the same time.
