      Mobile App Development Review from Undisclosed

      Alexandra and GroupBWT did great job! Provided us with the detailed audit for our system, specified how it can be improved, what should be paid attention to during the re-design and provided the best practices we can utilize. Also they formed clear and detailed scope of work for the further re-design. They definitely know how audit should be performed and the deliverable was even beyond my expectations. Strongly recommend Alexandra and GroupBWT team!

      Web Design Review from Nick Scarpino

      Americaneagle.com has a seamless process from project ideation through completion. I found a lot of value in the system they have for mocking up the site during the design phase. Seeing the site on a mobile device and a desktop computer at that stage in the process was critical.

      David B's Review Sourced from Google

      I want to share my experience so others are aware of the tactics this company uses. I was first contacted via an unsolicited spam text message promoting app development services. I had never heard of this business before, nor did I request any information from them. To see who was really behind the spam, I replied with a simple question about app pricing. The next day, I was contacted directly by this company.What was most concerning is that they tried to claim I had emailed them asking for their services — which is completely false. I never sent them an email or initiated any legitimate contact. The only reason they had my information was because of their own spam outreach. This is both misleading and dishonest.Professional companies do not need to resort to spamming strangers or fabricating stories about how potential clients found them. This type of behavior demonstrates a serious lack of transparency and integrity. If a business cannot be upfront and honest during the very first interaction, it raises major red flags about how they would handle a client’s project, communication, data, and money over time.Based on my experience, I cannot recommend this company. Trust is one of the most important parts of choosing a development partner, and unfortunately, their conduct showed me they are not worthy of that trust. I strongly advise anyone considering working with them to be cautious and look elsewhere for reputable professionals.
