Project Summary

Blink22 developed the iOS version of a money-management app for KhataBook, working from provided requirements and using Figma for design.

The client praises Blink22's professionalism, communication, and reliability in meeting timelines.

Key Challenges

Rapid growth with insufficient in-house engineering capacity
Need to develop an iOS version of an existing Android app and address additional product requirements

Project Deliverables

Project Solution

Blink22 built an iOS version of the client's existing Android money-management app. The vendor broke client requirements into development tasks, provided cost estimates, developed the iOS app, and did limited frontend work on Android; design, wireframes, and prototyping were produced in Figma. Blink22 continues to work as part of the client's team and follows standard project management practices using Jira and Slack.

Project Outcome

iOS app exceeded one million downloads and trended in India
Achieved a 4.4-star rating with ~35,000 reviews and strong organic ranking
App size reduced to ~10MB and achieved a 99.7% crash-free rate
Early success metrics: single-digit Google rank within 60 days and 300,000+ downloads shortly after launch

Quality of Deliverables

“The mobile app’s iOS version has reached over a million downloads, and it’s on the top business category chart. The app is also well-made; it’s crash-free and light. Blink22 is professional and communicative, and they set realistic timelines. They deliver on time, and they’re also cost-effective. This review is an update by the client company.
