How to utilise this in your designs

During sign-up, you could try showing how many of a user's phone contacts have been active recently, as social proof from real friends tends to persuade more than strangers.

Snapchat Add Friends screen with "31 of your contacts were online this month!" shown. Quick Add list includes Amanda, Steohanie, Rory with blue checkmarks and green online dots.

Snapchat

When users choose between options, you could add specific social proof to each one, alongside a rating of how well matched that option seems to be for them.

UI shows four colorful card options: Quiet your mind (92%), Get things done (88%), Be confident (79%), Keep your cool (54%) each with match %, learners count, and purple Add buttons.

Example from

Ahead

You could frame a user's next milestone with social proof, showing how many others are about to hit that same target, so the goal feels achievable and shared.

The app UI features "Getting sober" with Day Zero, "Next milestone" Day One due in 23 hours, plus "You and 491 others have this milestone next," highlighted by an arrow.

Example from

I Am Sober

When users choose between routes, you might ease hesitation with a short line of social proof, e.g., noting that one has been 'taken by many' drivers.

GrabMaps route selection UI shows two route options: 49 min 60.2 km "Best" with 3 traffic lights, tolls, RM9.03 cost, "Taken by many Grab drivers," and 52 min 57.2 km "Shortest distance."

You could try showing a live count of how many people are doing the activity right now, using social proof as gentle pressure for users to start too.

Calm meditation app UI shows sessions "Have a Heart," "Memories" with 668 meditating (underlined), and a yellow-orange session card noting 671 meditating together (underlined).
