About BLACTAIL

Native and cross-platform mobile apps

Blactail is a software development company based in Delhi that builds native and cross-platform mobile applications for Android and iOS. The company describes itself as an Indian software house that takes the whole mobile app development process off the client's hands, from the first conversation through to publication in the app store.

From first conversation to launch

The process starts with a discussion of the client's requirements. A technical expert then arranges a call to talk through the idea in detail, usually once a non-disclosure agreement has been signed. The team plans and builds the product in a predictable way, and the company says it aims to avoid surprises along the way. The work ends with submission to the App Store and the product's launch.

User experience and interface design

The company says it is specialised in smooth, attractive UI and UX design that gives users a good experience. The design work sits in the same team that writes the app, so the interface and the code are planned together and the collaboration that follows is set up to produce better results.

Serving startups and larger enterprises

Clients include startups and established enterprises. The company names fintech, edtech, foodtech and healthtech among the industries it has built products for, and it describes its technology consulting as serving businesses across a range of sectors.

Custom apps for Android and iOS

The company builds customised Android and iOS apps designed to meet each client's expectations. Its team is made up of mobile app designers and mobile application developers who work to the client's requirements rather than a fixed template.

Corporate wellness and other projects

Beyond consumer and business apps, the company's material refers to corporate wellness programmes that address mental health at work. It also describes its focus on computing, IT and networking, where it says it offers technology solutions for organisations that want to develop their own projects.

Based in Delhi

Based in the capital of India, the company says it draws on the city's technology talent and its own consulting experience. It says it has advised more than 92 businesses in a range of industries.
