FAQ
Frequently asked questions
-
Is the app free to use?
Yes. The app is free to download and its basic features are available at no charge.
A sponsored challenge may also involve the sponsorship amount, a 2% operator fee at completion, and network fees. Review the amount shown before confirming an operation.
-
What happens to the sponsorship if I don't reach the step goal?
The recipient for an unmet challenge is set when the challenge is created.
Review the challenge conditions and recipient shown in the app before joining.
-
If I miss my daily goal even once, do I fail?
Not necessarily. How many days out of the period count as success is agreed in advance when the challenge is created.
You can design it as, say, “hit the goal on 5 out of 7 days and it counts” — so you can start with a bar that works for you.
-
Who manages the sponsorship?
The sponsorship is held under the rules set when the challenge is created.
When a blockchain transaction is used, the applicable conditions and recipient are shown in the app. Review them before confirming.
-
Can I use it without crypto knowledge?
You can review the goal and challenge conditions in the app before deciding whether to join.
If a challenge uses JPYC, see the JPYC page and the current in-app instructions before proceeding.
-
How is this different from a regular step counter?
A regular step counter is centered on recording steps.
ESPL combines a step goal and period with optional sponsorship and recipient settings.
You can walk for yourself, or design a challenge to have someone you care about walk.
-
Can I use it without involving family or friends?
Yes — challenges that work solo can be created.
You can also invite family, friends, or a sponsor when that suits your challenge.
