Mobile App Functionality Development for Plant Desings Co

5.0 Feb 26, 2024

After a rough start to the project which was partially due to the state of the code Indeema inherited, the Indeema team made a breakthrough about 8 months after starting the project in that enabled clear and measurable progress. While the initial milestones took much longer to reach than originally estimated, once these issues were solved I was able to work with the team on additional changes and improvements in a productive manner. The app works as intended, and communication with the Indeema team became mostly seamless by the second stage of the project. After figuring out the code that they inherited which was not in an ideal state, and after some changes to key personnel, communication surrounding expectations and timeline became very transparent.

Mobile App Dev for Full-Service Technology Agency

5.0 Oct 10, 2017

They are very responsible and accessible; you can reach them pretty much 24/7. If something needs to be done, it doesn’t matter that they are in a different time zone, they always dedicate a project manager who can answer the call, or send a chat message back. Communication has never been an issue. Even if we find something critical, or our customer finds something that needs to be fixed, their turnaround time is really fast, and things are sometimes done overnight.

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.
