Achieve the best possible visual quality

Real-time comparison of expected and implemented design. Built into iOS simulator.
We made Flawless for those, who are obsessed with quality of mobile apps.





We believe, that everybody should become a better professional and achieve the very best we can. Every day, at every project, with every mobile app.
Amazing people support our vision — our first users, opinion leaders, friends and advisers. We are making Flawless App together with them:
  • Alex Shelpuk was involved in many our user interviews. He suggested several tech solutions for the current version of Flawless App. Alex works as a Head of Software in famous pet startup, Petcube.
  • Pipedrive founder, Ragnar Sass kicks our asses all the time. He motivates us to move faster and work smarter. And, we founded Flawless at his hackathon, Garage 48.
  • Sergey Lem is the fastest bug reporter ever. He tested our builds 5 minutes after we sent it! Thanks to Sergey Flawless App is so polished now :)
  • Sergii Zhuk is senior Android developer, our friend & advisor. We talked with him about Flawless even before Flawless App was done. Sergii always helps us!
  • You probably have heard Vixentael security talks. Anastasiia Voitova is a lead engineer, mission-driven speaker and red-hair Swift magician. She made for us 2.5h lecture on designer/developer workflow and how to fit Flawless App in it.
  • Andrey Skrupnic is a Head of Software in hardware startup, Concepter. He pushed us to launch paid product faster! It’s very inspiring advice from one of the first alpha users.

  • We met with Alexsander Akers during our Berlin trip. He gave us very useful insights on iOS development workflow in big product companies. Alexsander proposed ideas on integrating our product into that workflow.
  • Hector Zarate showed us how designers and developers can smoothly work together, even on such complex modular apps, like Spotify. Also, he kindly explained the concept of design language in dev environment.
  • Ignacio Romero is iOS developer in our beloved Slack. Thanks to Ignacio we fixed the signing issue. New users will no longer see the warning message: “this app is from an unidentified developer...”
  • Artem Novikov works as a Senior UX Designer in the huge Ukrainian development company, EPAM. Artem was with us since the first alpha version and helped to polish our product UX.
  • Kate Gridina is a proactive Ukrainian iOS developer. We met her in Berlin. She described development workflow in large e-commerce mobile teams. Also, Kate shared Flawless with fellow engineers to get us more feedback.

  • Peter Witham stays with us since the first day and till now (thanks God!). He often reported weird crashes, suggested new features, helped us with PR and proofread our texts. Perfect user!
  • Artem Stepanenko is Ukrainian iOS Engineer. While we were visiting Berlin, Artem shared a lot of insights on visual quality control and how it usually checked in Europian companies.
  • Marat Ryndin was very honest about our first buggy product. Marat is a product designer and thanks to his UX reports we fixed many weird interactional issues.
  • As a senior design manager, Bogdan suggested us many cool features to make Flawless App useful for design teams. Bogdan Pryshedko introduced us to his ex-team at Yalantis, who beta-tested our product :)
