Shortcut: Instant Chat
Send Messages Without Saving Contacts
The brief
Context and goals
Our role: Mobile App Development, UI/UX Design, Message Intent Integration.
Shortcut: Instant Chat provides users a quick and convenient way to send messages using popular messaging platforms without needing to save the receiver’s contact number, simplifying instant communication across apps.
Built as a utility tool by Karma Technolabs, Shortcut: Instant Chat streamlines the process of starting conversations on major messaging apps by removing the friction of contact saving. By supporting WhatsApp, WhatsApp Business, Telegram, Viber, and Snapchat, the app allows users to enter a phone number or ID, compose a message, and send it with a single tap. The focus is on speed, efficiency, and reducing unnecessary steps in everyday messaging tasks.
Since its launch, the app has been improved with UI enhancements, performance optimizations, and extended support for multiple platforms, making it a practical tool for both personal and professional quick messaging requirements.
Requirements
What the product had to achieve
Deliver a fast, frictionless messaging experience without traditional contact requirements.
Support Multiple Messaging Platforms
Offer seamless quick messaging across WhatsApp, Telegram, Viber, Snapchat, and more.
Simplify Input Workflow
Design an interface where users can quickly input, send, and complete messaging actions with minimal taps.
Deliver Consistent Performance
Ensure the app runs smoothly on a wide range of devices with quick loading and minimal footprint.
Our approach
Problems we solved
Technical and UX challenges overcome to support reliable multi-platform linking.
ChallengeReliable Multi-Platform Linking
How we solved itIntegrating deep links across multiple messaging platforms required precise intent handling and fallback validation. We implemented robust URI schemes and conditional app detection logic to ensure accurate redirection without crashes, misrouting, or unsupported platform errors.
ChallengeUser Input Efficiency
How we solved itThe core experience depended on minimizing friction in number entry and platform selection. We optimized form structure, auto-focus behavior, and validation flows to reduce taps while maintaining clarity and preventing incorrect input submissions.
ChallengeBroad Device Performance
How we solved itTo ensure smooth performance across diverse Android devices, we optimized widget rebuild cycles, reduced unnecessary state updates, and streamlined layout rendering, resulting in consistent responsiveness even on lower-end hardware.
