5 public challenges you can start with friends this week

10/07/2026

If you already know what you want to do, the hard part usually is not planning. It is follow-through.

That is why DealUp works better when the challenge is concrete, visible, and easy to explain in one sentence.

Below are five public challenge ideas that work especially well in DealUp because they are simple to start, easy to share, and obvious to watch.

1. Be on time all week

Challenge idea: Show up on time for every planned meetup this week.

Why it works:

  • Easy to explain
  • Easy for friends to understand
  • Easy to verify
  • Naturally social

2. No sugar for 7 days

Challenge idea: No dessert, sweet drinks, or late-night sugar for 7 days.

Why it works:

  • Clear pass-or-fail moments
  • Easy proof updates
  • Relatable to a lot of people

3. Screen off after 9 PM

Challenge idea: Put the phone down after 9 PM every night this week.

Why it works:

  • Concrete daily deadline
  • High self-control tension
  • Easy story to share publicly

4. Save $100 this month

Challenge idea: Cut impulse spending and save the first $100 this month.

Why it works:

  • Simple target
  • Easy progress story
  • Good for friend accountability

5. Post proof of one workout every day

Challenge idea: Post proof of one real workout every day for 7 days.

Why it works:

  • Easy daily check-in
  • Obvious momentum
  • Social proof helps the habit stick

Why public challenges work better than vague goals

A vague goal sounds nice. A public challenge creates tension. When people can follow along, the question changes from “Do I want this?” to “Will I actually do it?”

If this challenge fits, open it in the app

This page explains the rule first. The app is where you invite friends, post proof, and keep the result visible from the first round.

Cold traffic should keep sharing public challenge pages first. Warm traffic can go straight to the App Store.
