Make Your Website Elements Unique

People often ask a 'techie' friend to design a Sign Up Form for them or hire a 'web guy' that one of their friends referred.


Others look overseas or for low-cost open source alternatives for Sign Up Form.

Get Back More Time With POWR

Also, customizing these apps usually requires coding experience or another designer to help -- costing even more resources.


In a world where scammers infiltrate sites every day, many other Sign Up Form apps out there aren't built with security in mind, which could expose your customers or worse -- crash your whole site. Not with POWR!

CASE STUDY: POWR put Rbia Shades on the success track

A few months after Rbia Shades launched at local fairs and craft shows, they were looking for a way to sell online.


They wanted to visually appeal to site visitors and demonstrate the quality of their product and lightweight, ergonomic designs.


Their web host did not provide an adequate solution for this, and after some research, decided to give POWR a try.

Shortly after signing on with POWR, Rbia’s first step was to install a popup. They increased their contacts by over 250% (over 600 real contacts).


Soon after, they added our Social Feed app and grew their social media following to over 6000.


Next, they added a Media Slider as a visual way to quickly show their products to new site visitors as they entered their homepage to show how the accessories looked in real life. It showcases their products well and gave customers a great on-site experience.


In fact, they quickly found that visitors who interacted with POWR apps on their site stayed engaged 2.5 times longer than ever before.
