Frequently Asked Questions

What is SPAR!?

SPAR! is a fun and social way to build healthy habits.

It’s simple:

  1. Challenge your friends to do something, on a set schedule. (“Hit the gym, 3x a week”)
  2. “Check in” when you do the challenge activity by posting fun video selfies for the group to see. SPAR! keeps score so you always know where you stand.
  3. A challenge creator can choose to add a cash penalty for missed check-ins. At the end of the challenge, the winner gets the money!

What makes SPAR! effective?

SPAR! works because it’s fun. Try a “Dance party” challenge or “Learn a new instrument” with your friends – you’ll see.

SPAR! also works because it penalizes failure. Losing money sucks. When there’s a fee for missed check-ins, SPAR! makes you pay for your own laziness. Want to get fit? Try 50 push-ups a day for 1 month, with a $20 penalty. You won't miss much.

How many people can participate?

As many as you want. We've found that challenges are most fun and intimate with about 20 players max.

Why do you need my debit or credit card?

If you’re not playing for cash, we don’t need any payment info

But SPAR! works best when there’s real money on the line. To join a challenge with a missed check-in penalty, we require a card on file, to make sure you pay up as promised for any misses.

When does a challenge start?

Challenges begin at 3am the day after the creator hits start. This ensures everyone has time complete the first check-in, with no unfair surprises.

Why is the daily check-in cutoff 3am the following day?

Because people often stay up late! A 3am cutoff time gives you time to complete your check-ins before your day ends, without having to scramble to meet an artificial deadline at midnight.

Can I join a challenge already in progress?

Yes. Invited players can still join a challenge for 24 hours after it has started. You can also leave the challenge without penalty during the same period.

Can I quit a challenge already in progress?

Yes. You can leave a challenge penalty-free in the first 24 hours. After that, you can quit by selecting "give up" and paying a flat $20 fee into the pot.

What happens in a tie?

If there's a tie, the players with the fewest misses split the pot.

If no one misses any check-ins at all, then no money is exchanged.

What if not everyone I invite wants to do the challenge?

No problem. Challenges are opt-in, so if someone you invite doesn't respond or isn't interested, the rest of the group just plays without them.

My friends are cheating — what can I do?

Get better friends. Seriously. Challenge creators can “flag” to strike bogus check-ins, but come on: lay down some peer pressure and remind your friends that there are no cheat codes in life.

How do I get my money?

When you win a pot, the money accumulates in your in-app balance, which you can see in the settings page.

When you’re ready, you can cash out and send your balance to your bank account. Missed check-in fees are always deducted from your in-app balance before charging your credit or debit card.

How does SPAR! make money?

SPAR! takes a 10% cut of every pot. Credit card transaction fees and engineers are expensive!

Do you have a version for Android?

Not yet – we will soon!

Does it work outside of the US?

Yes. Currently SPAR! works in the US, Canada, the UK, Australia, and New Zealand.
