      AI Development Review from Julia Antoci

      Leanware built the mobile MVP of our AI fitness assistant for iOS and Android. It started with discovery workshops that sharpened the product vision and shaped an MVP roadmap prioritizing launch features while leaving room for expansions like avatars and real-time feedback. They developed a conversational AI engine with custom prompt and context engineering tailored to fitness conversations, one that keeps continuity across sessions, remembers user progress and preferences, and keeps health guidance within safety standards. On top of that they implemented photo-based food recognition, smart search that understands fitness intent, personalized recommendations, progress tracking with AI-generated insights and coaching suggestions, and gamified response formats that make AI answers easy to read, plus the scalable backend behind it all. Their consultation saved us an estimated 20 to 30 percent in costs by avoiding unnecessary complexity, and we launched a functional MVP across the app stores in under eight weeks, faster than planned. Project management was exceptional: clear timelines, on-schedule delivery, and proactive communication via Slack, with expert recommendations guiding decisions rather than every choice being pushed back to us. Their technical skill and creativity made the whole thing feel less like hiring a vendor and more like building with a co-founder.

      Software Development Review from Anonymous

      Leanware delivered two significant projects for our e-commerce platform along with a steady stream of smaller fixes and enhancements. They built a new employee management page in our back office so our customers can create accounts, set permissions, and link employees to entities on their own, and when our mobile app's chat functionality needed replicating in the back office, they built a custom chat and messaging React library from scratch, integrated seamlessly with our design system and existing bespoke solution. Along the way they worked comfortably across Next.js, React, React Native, Apollo, GraphQL, and Hasura, and adapted to our implicit conventions. We ran week-long SCRUM sprints with check-ins three times a week, and they consistently hit the sprint goals on time; even when we needed hard pivots mid-sprint, they adapted without losing pace. As the engagement progressed they increasingly took the lead, asking well-informed questions and offering suggestions on code, product, and design that genuinely enriched the outcomes. What impressed us most was how swiftly they onboarded: given incomplete product descriptions, they asked the right questions to fill the gaps and picked up our undocumented code patterns without getting stuck on minor details. It felt like one cohesive team working toward shared objectives, free of the friction that usually comes with a third party

      Mobile App Development Review from Anonymous

      Leanware has partnered with us since Q4 2023 on two cloud-based mobile apps for iOS and Android, one built in Flutter and one in React Native, handling development on both and the UI/UX design on one. For one project they staffed a team of five mid-level developers, a senior developer, an architect, and a UX designer available as needed. They also took over an app that was unstable and nowhere near production-ready and turned it into a stable, solid product I'm genuinely proud to show. Their processes leave nothing to chance and the code that comes out of them is excellent; they've been flexible and thorough throughout. They meet deadlines, keep their promises, and are careful about what they commit to. The whole team has been great, and Alvaro, their Technical Product Manager, deserves a special mention for being remarkable. I hired them because they were upfront about what they could and couldn't do, and that honesty, together with the tremendous quality of their work, is what separates them from other providers. Both are getting harder to find these days.

      Web Development Review from Raj Sardana

      After working with Webisoft for a few months, I'm really pleased with the caliber of support and output I've had. I manage a little business, so I'm highly involved. I am aware that I have managed previous marketing companies a little too poorly in the past. However, Webisoft has shown me a great deal of patience and has taken the time to comprehend my unique demands and create a plan to address them.

5 Frequently Asked Questions About AI App Development Companies

How much does it cost to build an AI app?

Simple AI integrations using third-party APIs (e.g., OpenAI or Anthropic) or off-the-shelf builds can cost about $5,000-$20,000. For instance, a chatbot or search engine recommendation system.  

More complex AI applications with custom workflows, multiple integrations, and a polished UI range between $100,000 and $250,000. Enterprise-level builds that require custom-trained models and large-scale data pipelines can cost over $500,000. 

How long does it take to build an AI app?

A basic MVP using a pre-trained or off-the-shelf model can take around 2-3 months. A mid-complexity app, with custom features, multiple data sources, or advanced workflows, may need at least 4-11 months to build. 

Ultimately, the AI application development timeline will depend on your project's scope, complexity, security and compliance requirements, and business readiness. 

What is the difference between using an existing AI API vs. building a custom model?

An existing AI API (e.g., OpenAI, Anthropic, Gemini) offers access to a pre-trained model through a paid subscription or usage fee. This model is faster to launch, has lower upfront costs, and requires no in-house AI expertise to maintain. 

A custom model is built and trained on your own data, providing more control over accuracy, behavior, and proprietary advantage. However, it costs significantly more, takes longer, and requires ongoing retraining and infrastructure.  

Consider choosing custom AI if you have niche domain data, strict compliance requirements, and AI is your main differentiator. 

What AI features are worth adding to an existing app?

The AI features worth adding to an existing app will depend on your core business needs, goals, and existing tech stack. 

For companies moving beyond isolated AI features, AI-native workflow redesign involves rethinking processes around AI rather than simply adding AI tools to existing workflows.

The same study also found that 44.4% of tech founders believe that automation is the most beneficial AI feature, followed by customer personalization (22.2%) and AI-assisted productivity features (22.2%). 

How do you ensure data privacy and data security?

Reputable AI app development companies will isolate your data through encrypted storage (at rest and in transit), strict access controls, and clear data-handling agreements with any third-party AI providers used. 

To confirm the AI application development company’s legitimacy, consider the following: 

  • Search for compliance certifications relevant to your industry (e.g., HIPAA, SOC2).  
  • Require a written data processing agreement (DPA), which outlines where data is stored, who has access, and how it’s deleted.  
  • Obtain a copy of the AI API’s Terms of Agreement. It should explicitly state that the company and its model do not use your data for training.
