Some customer testimonials

Our customers recommend us.

Simonini has been the partner of SBCBM - the Brazilian Society of Bariatric and Metabolic Surgery since 2019 in the development of the groundbreaking BARILIFE app, dedicated to patients who have undergone bariatric surgery. Their commitment to development, dedication in finding solutions and the challenges overcome throughout these years allowed us to reach 370 thousand users on the platform in 2025. We thank Simonini for their dedication in continuing, together with our Board, the work on this app that is a pioneer worldwide.

Since we started our partnership with Simonini Software in 2020, we have counted on a team that is accessible, fast and always engaged in solving problems. They are also extremely proactive, bringing ideas that truly improve our app. The team goes beyond what is expected, always suggesting strategic improvements and ensuring a stable experience for users. This dedication and commitment have made Simonini Software an indispensable partner for Hyupp's growth.

Ahmed Kadura

CEO • Hyupp

I have been working with Simonini for over 5 years. I have also recommended them to other friends in the market. They have never disappointed me or left anything unresolved. They have never answered me with something like "it's not my fault". They have always been 100% committed and open to new projects, new features and also to necessary fixes. They work with great expertise and creativity, delivering on time and with quality. They are truly responsible and competent. Before Simonini, I tried 4 other companies and couldn't make progress. I finally have a technology PARTNER for my business.
