Delivery Approach
Vibe set out to replace endless swiping with something more deliberate, matches based on real compatibility. Intobi built the app fast, without compromising on personalization, through a focused, phased approach.
Discovery
Intobi began by rethinking what makes a dating app meaningful, compatibility over endless swiping, and defined the core: a survey-driven matching engine, location-aware date suggestions, and an onboarding flow that feels thoughtful rather than tedious.

Matching system
Intobi built a robust compatibility engine that automatically connects users with the most relevant profiles. Users simply complete an extensive, dynamic questionnaire on personality, lifestyle, and preferences, then let compatible matches come to them.
Fun activity suggestions
To replace awkward, repetitive first dates, Vibe recommends unique activities based on users’ interests and proximity, simplifying date planning and encouraging more memorable, natural first encounters.
Match and set a date
Users can send structured date proposals before entering a chat. Once a date is confirmed and a small fee is paid, users move seamlessly into chat to plan the details, increasing the likelihood of actual meetups.
Smart scheduling & availability sync
An intuitive interface guides users through the entire process, from onboarding and matching to selecting activities and confirming dates. Micro-interactions, animations, and structured flows keep the experience playful yet highly functional. Suggested time slots, availability prompts, and automated reminders reduce drop-offs between matching and meeting.
Seamless in-app experience
Suggested time slots, availability prompts, and automated reminders reduce drop-offs between matching and meeting, ensuring dates are set quickly, clearly, and with minimal user effort.
Results
The personalized, compatibility-first approach delivered measurable gains in matching, retention, and engagement – a location-aware date engine lifted first-date acceptance 10–12% while cutting decision fatigue, dynamic surveys pushed average sessions to 12–14 minutes, and 85% of beta testers called onboarding “thoughtful.”
