      Awital Ifrah Program manager at Masa Israel journey
      5.0
      Cross-Platform Review from Awital Ifrah

      Masa came in with a pretty loose idea and AppMakers helped turn it into something solid. What I appreciated most is they didn't overcomplicate it or try to make it into some giant monster platform. They listened, asked smart questions, and helped us focus on what would actually matter for alumni and current participants. The end result felt thoughtful and realistic. I'd definitely work with them again.

      Startup Review from Moishi Stern

      We create live events. We wanted a site that shows what we do without making people dig. AppMakers listened, trimmed the fluff, and gave us pages that read fast and look good on a phone. The quote form asks the right things and our team can update galleries without calling a developer. They stayed on schedule and answered messages the same day. The whole process was calm and clear. We already see better inquiries. It feels like a real upgrade, even before the full rebuild.

    JanBask Digital Design Reviews & Testimonials

    • Terry Heller
      Terry Heller CEO at Preferred Roofing
      5.0
      Web Development Review from Terry Heller

      As a growing roofing company, we knew our old website wasn't doing justice to the kind of work we do at Preferred Roofing. It looked outdated, was hard to navigate, and didn't reflect the level of professionalism we bring to our projects. We wanted to change that. Our main goals were to create a new website that would clearly show our services, build trust with new visitors, and make it easier for people to contact us or request quotes online. We also wanted the site to work well on mobile phones because a lot of our customers use their phones to search for roofing services.So, we hired JanBask Digital Design to completely redesign and develop our website. We were looking for a partner who would not only build us a great-looking site but also guide us through the process and make sure the site helped us grow our business.They asked detailed questions about our services, customer base, and how we wanted people to feel when they visited the site.Scope of the work included:Designing a responsive website from scratchCreating unique pages for all our services (roof repairs, installations, gutter services, etc.)Adding a clean, easy-to-use contact form and quote request systemThe new website has made a real difference for us. We've received more calls and quote requests since the launch, and customers often mention how easy it was to find what they were looking for on our site. The new layout makes our services very clear, and the site feels clean, modern, and professional which is exactly what we wanted. It has definitely helped us build more trust with new visitors.Project management was excellent. JanBask kept everything organized and walked us through each step. They gave us regular updatesWhat stood out the most was their care and attention to detail. They didnt just build a pretty website they made sure it worked for our business. They didnt rush the process either they truly wanted us to be happy with the final product.

      Web Development Review from Jason Anish

      When we approached JanBask Digital Design, our companyAustin Financial Services, Inc.was going through a critical branding transition. While weve been around for over 40 years and have built a solid reputation in asset-based lending, our online presence didnt reflect the trust, speed, and flexibility we offer to our clients. We needed more than just a website redesignwe needed a digital experience that could communicate our value, streamline how potential clients learn about our services, and ultimately drive real business conversations.We specifically hired JanBask to help us accomplish a few main goals:Modernize our websites look and feel without losing the credibility and seriousness expected of a financial company.Improve the user journey for business owners and financial decision-makers who are looking for fast, flexible credit solutions.Create a strong foundation for future digital marketing efforts like SEO, paid ads, and client onboarding automation.Make the site mobile-friendly and easy to navigate, especially for busy executives browsing on the go.We had tried updating our site with internal resources and freelancers before, but it never really hit the mark. So we were cautious going inbut hopeful.JanBask started the project with a series of discovery calls where they really took the time to understand not just what we do, but why we do it and who we do it for. They dug into our client personas, our lending process, and even how our sales team follows up on leads. It felt like they werent just designing a websitethey were building a tool tailored to how we actually work.What stood out most to us was their ability to translate financial language into something both clear and client-friendly. Were used to dealing in technical lending terms, but JanBask found a way to keep things professional and easy to understand. Thats not easy to pull off.

      We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.

      For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

      I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Frequently Asked Questions

What is a cross-platform app development company?

A cross-platform app development company is a company that offers a seamless approach to mobile app creation. It goes beyond the traditional method of building separate apps for iOS and Android, opting instead for a single codebase that utilizes cross-platform frameworks like React Native or Flutter.

Businesses look for cross-platform mobile app development services because of these challenges:

  • Low or declining brand visibility and sales
  • App development using two code bases is slow and inefficient
  • Updates are limited and slow to deploy
  • Costly maintenance fees
  • Limited app functionalities and features

With cross-platform app development companies, businesses can experience faster development times and potentially lower costs. Their framework experts ensure the app functions flawlessly on both iOS and Android devices, creating a flexible app that can reach a wider audience without the burden of maintaining separate codebases.

Success story

In the following success story chosen by our experts, we highlight how a cross-platform mobile app development company improves business efficiencies:

  • Challenges: An American video rental company needed to upgrade its existing mobile app that was built with outdated coding practices, faced performance issues, and lacked device and orientation optimization. Its user interface (UI) was not intuitive, and it failed to load on a variety of devices.
  • Solutions: Simpalm refactored the codebase, improving app performance and ensuring smooth operation on modern devices. Its new intuitive UI was now optimized for various devices and orientations. The team also integrated a proprietary AI engine alongside an off-the-shelf solution to create recommendation algorithms. These algorithms learn user behavior and suggest relevant content and deals, driving higher in-app purchases and monetization.
  • Results: The collaboration improved the client’s mobile app. This resulted in increased user engagement, higher in-app purchases, and greater monetization for the client.

What do cross-platform app development companies do?

Cross-platform app development companies specialize in creating mobile apps that function seamlessly on both iOS and Android devices using a single codebase. Here’s a breakdown of their core services:
