I´ve been testing several ad builders, a lot; Celtra wins in every parameter, easy to use, scalable, fast, solid, friendly environment, metrics, reports, etc

It can easily be used for templated designs.

I appreciate Celtra Ad Creator the most for its remarkable usability, speed, intuitiveness, and power. The component-based drag-and-drop platform is known to create a "templated" design; however, this has been proved wrong as it provides comprehensive features that let you make captivating ads with HTML5 mobile technology swiftly. Compared to bulky Flash banners, which take a reasonable amount of time in quality assurance tests, code-free creation via Celtra removes such issues while still producing reliable results ideal for professionals in the visual arts industry.
