Web & Mobile App Design & Dev for Women's Fitness Company

I’m not very technical, so I called them again and again for updates, and they were always kind and answered me on time. Synergy Labs was also open to making changes for free. They provided three months of free maintenance. Half of the team was girls, so we talked a lot about the project, how it should be, how it should look, and why people should choose our product when there are so many fitness apps. I checked the process and performance through a board, including finished and pending tasks.

Synergy Labs didn’t limit themselves to development. They suggested adding features and three different plans for my services. For example, I hadn't thought about having a page for videos, but they showed me that it would be more organized to have videos on the app rather than having users go to YouTube. They did deep research before going into the task, clarified my needs, and checked if their needs conflicted with mine.

Why Trust Clutch

At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.

Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.

Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.

We evaluate service providers using a structured methodology that combines:

In-depth client interviews and ratings
Comprehensive project details
Market presence
Portfolio examples and industry recognition

This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.

Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.

We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.

Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.
