Best Free Step Challenge Apps for Groups and Friends (2026)

What Makes a Step Challenge App Worth Using

Four points decide whether an app works for a group step challenge: what the free plan gives, whether the challenge can be private, who pays for a bigger group, and whether the app checks the steps.

A free plan is not always the same thing. In this guide, "free" means that a person can create a challenge, invite friends, run it and see a leaderboard without paying. Some apps let anyone join for free but put private challenges or bigger groups behind a paid plan. Check who pays: the host only, or every member.

Private challenges matter because most people want to compete with people they know. The social accountability comes from the names on the leaderboard. A public challenge with strangers does not give the same push.

Step checks matter because one person who fakes steps spoils the challenge for everyone. Some people shake the phone, type a step entry in a health app by hand, or give a tracker to someone who walks more. An app that accepts any number puts that result on the leaderboard.

What Upkeep's Free Plan Gives You

Upkeep is a step challenge app for private groups on iPhone and Android. Challenges are invite-only. The host sets the daily step target, from 3,000 to 50,000 steps, and the length of the challenge. Any host can turn on auto-roll, so a new round with the same people starts when the challenge ends. Steps sync from Apple Health on iPhone or Health Connect on Android. Manually entered steps never count.

Members always join free. On the free plan, a host can run a group of 3 to 15 people for up to 7 days, and up to 3 duel or group challenges at the same time, plus solo challenges, which do not count toward that number. For a bigger or longer challenge, only the host pays.

Pacer, Stridekick and Strava

Pacer: Pacer is a pedometer and walking app. Its App Store listing says it counts steps when the phone is in your hand, pocket or bag, and syncs with Apple Health and Apple Watch. The listing mentions friendly challenges and walking groups. It offers a free version and a Premium subscription; the listing shows Pacer Premium Yearly at $49.99. The listing does not say which features are Premium only. Pacer's site says you can start a free step challenge, invite friends, family or coworkers with a link, and follow a shared leaderboard.

Stridekick: Stridekick runs step and activity challenges for friends, families and workplaces, and lists 11 challenge modes. It connects to wearables such as Fitbit, Apple Watch, Garmin, Withings, WHOOP and Oura, or tracks with a smartphone. The Free plan has public challenges only, up to 7 days long, for 10 participants, with 5 challenge modes. Private challenges need a Pro plan, from $12.99 a month for 10 participants and up to 45 days. Only the organizer needs Pro; participants join with a free account. Read the full Upkeep vs Stridekick comparison.

Strava: Strava is a social app for running, cycling, hiking and over 50 other sport types. Its App Store listing describes monthly challenges that earn digital badges, and clubs with channels, routes, events and polls. It has a free version and a paid subscription. The listing does not mention step counting.

StepBet, Habitica and Outwalk

StepBet: StepBet is a step game with real money. You bet into a pot to join a game, and you must reach personalized step goals each week. Most games are six weeks long, and most bets are $40. Players who reach their goals for the whole game split the pot. StepBet keeps 15% of the gross pot to pay referees, transaction fees, game hosts and support. It says it does not generally have free games. StepBet connects to your tracker for step counts, monitors steps and can ask a flagged player for more data.

You can create your own StepBet game for free, without a membership, and invite friends with a game code or link. The game runs for 5, 6 or 7 weeks. The bet options are $30, $40, $50 or any custom amount over $25. A game must have a bet of $40 or more to appear publicly.

Habitica: Habitica is a task and habit app that works like a role-playing game. You check off a task in the app when you complete it in real life, and you earn gold, experience and items. Parties let friends team up, and challenges are shared task lists. Its App Store listing does not mention Apple Health or step tracking, so a walking goal is self-reported. Habitica says it can be fully enjoyed for free, with an optional subscription from $4.99 a month.

Outwalk: Outwalk is a free step tracker with custom leaderboards for friends, global and regional rankings, and in-app chat. On iPhone it reads steps from Apple Health. The only in-app purchase in its App Store listing is Remove Ads for $1.99.

The Verification Problem

The biggest issue in a step challenge is trust: are the steps on the leaderboard real? Upkeep takes steps from the phone's health store, ignores manually entered steps, and checks synced days before a winner is final. A day that does not look like real walking can be removed from a challenge result.

StepBet also checks steps, because real money is at stake: it monitors steps and can ask a flagged player for more data. But that check comes with the bet. Each player puts money in the pot. On Upkeep, step checks are part of every challenge, and members join free. Read how to stop cheating in a step challenge for more.

Why Groups Choose Upkeep

Upkeep is built for a private step challenge with people you know. Members always join free. Each member passes or fails each day against the daily target, so the challenge rewards showing up daily, not one big day. Manually entered steps never count, and Upkeep checks synced days, so the winner earned it.

Friends on iPhone and Android join the same challenge, and an Apple Watch, Fitbit, Garmin or Galaxy Watch counts when its steps reach Apple Health or Health Connect. For a bigger or longer challenge, only the host pays for Upkeep Pro or a Creator Pass. To plan your first challenge, read how to run a step challenge.
