      Mobile App Development Review from Max Levchin

      We've partnered with HDWEBSOFT who have created our app using .NET. The feedback from our customers we've received has been overwhelmingly good. We had heard positive things about the idea even before we released the app, so it's encouraging to see those comments continue once it has been out. HDWEBSOFT was set up from the start. The design team was outstanding; they completed the job on schedule and within our allocated budget. They followed a well-defined procedure that was in place.

What impresses me most about Bytes is the level of value that they provide. Highly recommend.

      We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project. We appreciate the agency's dedication and professionalism.

      They worked on our app and continue to work on it to this day. We originally had a bad experience with various developers and ended up with a bunch of code and no functioning app - touchzen took the code and audited it and made it work and it work great now. Can't complain - still going to work with them and I would recommend to anyone who wants it done right.

      HashStudioz Technologies is a huge contributor in helping us update our systems. They've built internal portals for our customer base and our dealer base, and as we continue to grow, we use them to enhance those two solutions they created for us.Regarding the process, we start with a meeting to lay out what we want, whether it's a solution or an upgrade to a solution. We look to them for advice and insight, what theyve seen, and what they think is the best way for us to go theres back and forth communication regarding getting everything set up. After that, they put out a great statement of work for us and have a kickoff meeting to start the task weve known each other for so long that everything is routinary.we are delighted with the functionalities that HashStudioz Technologies has developed over the years, which has streamlined our processes. we also praise their friendly approach to explaining things and making everything smooth.

      HashStudioz Technologies developed our devices UX/UI so we could view and pull data. The goal was to have interface capabilities to turn the data into explainer graphs and the ilk. At the beginning of the project, I provided HashStudioz Technologies team with Arduino-based demo boards that interacted with specialized frontend hardware that captured usable data. I also gave HashStudioz Technologies information about the protocol and data format I was using. HashStudioz Technologies delivered a usable UX/UI that met our needs within two sprints, despite working with hardware they had no experience with. we were satisfied with HashStudioz Technologies's work and project management we had sprint review meetings and project progress meetings with the project manager.
