Appingine Reviews & Testimonials
David Dorough's Review Sourced from Google
I read reviews of almost 100 companies and spoke with reps from 5 before finally going with Appingine for my first app. I'm sure you can pay more for less quality from a different company but why would you? They were easy to work with and quick to respond to questions. They split the charges by stage of development like every professional company should.I needed to make several changes during development and the cost was reasonable. Anthony was awesome and helped me along every step of the way. Apple has more stringent requirements than Google and Appingine was able to get the app published on both stores. Looking forward to more projects with them. Once again, don't pay more for less, go with Appingine!

Rob has helped Valley Hi take its marketing efforts in newer and higher levels, thanks to their field knowledge and customer support. Thanks, Rob & Team!
ReVive Elite Care's Review Sourced from Google
We began working with TurnKey Digital in October, and our website officially launched in April. During our initial search, we spoke directly with the owner, who was knowledgeable and made us feel confident moving forward.Their team was responsive, professional, and highly collaborative throughout the process. As detail-oriented partners, we appreciated their patience and willingness to refine everything until it was exactly right.They delivered a beautiful logo and a cohesive website that truly reflects our brand. We’re extremely happy with the result and would highly recommend Turnkey Digital.
John Tanenbaum's Review Sourced from Google
My experience began in the planning stages back in the early spring of 2025 and every two weeks during the first 2 months we were in contact as the project took shape to develop the website. As the project progressed, we were having either weekly meetings or emails which accelerated the process. The last 6 weeks we were in constant contact, and the final end product was better than what we originally had hoped for our website. I can highly recommend Turnkey Digital to plan and execute your projects too. I am sure we will be utilizing their services in the future. John M. Tanenbaum, Castle Bay Management Services, LLC.

badpixel Reviews & Testimonials
Jessica Dally's Review Sourced from Google
"We loved working with badpixel!We had already started talking with some potential locations and we needed to quickly establish our logo and branding. With the questionnaire that kicked off our discovery, we were able to capture what we were looking for and it was clearly understood as we went into our first review and really liked what we saw. After a few modifications, we had our logo and style guide allowing us to start working on our social presence while the badpixel team continued to work on our Square website setup.Once the site was ready, they walked us through everything and we were able to jump in and take control! Getting a website up just before the holiday season was huge, it lead to our first sales and profit!"
Charlie Wellborn's Review Sourced from Google
Badpixel did an excellent job developing our site (shophearton.com). They were responsive, communicated consistently with us and our marketing team, and met our aggressive deadline. Thanks Sheila & Chris!
Joemoney 42's Review Sourced from Google
Working with Chris has been so easy and we could not be happier with the branding for our business! Always very personable and responsive to our input. No need to look elsewhere for great branding! Thanks!
