Welcome

A reason to walk, made with sponsorship.

ESPL is an app that helps you keep walking — by setting a step goal, a period, a sponsorship, and a recipient up front.

Whether you reach the goal or miss it, the sponsorship is delivered according to the rules you set in advance.

ESPL in 30 seconds

“Who does what, and where the money flows” — in three lines.

  1. Sponsor designs the challenge

    Stakes the sponsorship and decides the step goal, the period, and the recipients. The walker themselves, family, friends, or a company can all be sponsors.

  2. Challenger walks

    Steps are recorded automatically through HealthKit (iPhone) or Google Fit / Health Connect (Android).

  3. The sponsorship reaches a recipient

    On success, it goes to the success-case recipient. On a miss, it goes to the failure-case recipient. The distribution follows the rules you set in advance.

The sponsorship never disappears.
It always reaches someone — following the rules you set in advance.

02 / Actors

Only three actors

ESPL runs on these three roles. One person can play more than one of them.

  • Sponsor

    What they do
    Funds the sponsorship and decides the step goal, the period, and the recipients
    Examples
    Yourself, family, friends, your company, etc.

  • Challenger

    What they do
    Walks
    Examples
    Yourself, family, friends, etc.

  • Receiver

    What they do
    Receives the sponsorship based on the outcome
    Examples
    Yourself, family, a charity, the Sponsor, etc.

You can start solo

For example, you can be the Sponsor, the Challenger, and route the success-case sponsorship to a family member. You don't need to invite anyone — you can start today.

03 / First Steps

Four steps to begin

Download → Sign up → Connect steps → Practice challenge. “See details” on each card takes you to deeper help.

  1. Download the app

    Download the ESPL app for free from the App Store or Google Play.

    Go to download

  2. Sign up

    Launch the app and follow the on-screen guide to create an account. An email address and a passcode are enough — about 30 seconds to finish.

    See the signup steps (Japanese)

  3. Connect step data

    Connect HealthKit on iPhone or Google Fit / Health Connect on Android so your daily steps are recorded automatically. Android users — check the prerequisites first.

    See Android notes (Japanese)

  4. Try a practice challenge

    Before using a real sponsorship, try a small goal on the practice environment (testnet) — for example, “6,000 steps a day for 3 days”. Once you're comfortable, run a real challenge on the production network with family or friends as the recipient.

04 / Common Concerns

The four worries we hear most

Of the questions we get before people start, these four come up the most. Quick answers below.

  • Does it cost anything?

    Downloading the app and using its basic features is free. When you run a challenge with a sponsorship, you do pay the sponsorship itself (in yen-denominated JPYC) and a small blockchain gas fee (a few yen to a few dozen yen per transaction). There is no monthly fee.

    See JPYC and gas fees

  • If I miss the goal, does the sponsorship disappear?

    No. The sponsorship is distributed automatically to the failure-case recipient you chose when you created the challenge. You can route it back to the sponsor, to family, to a charity — anything decided in advance. The operator never confiscates it.

  • Aren't JPYC and wallets hard to deal with?

    No setup is required from you. The container for the sponsorship (your wallet) is created inside the app automatically when you sign up with an email address and a passcode. You don't have to manage private keys or seed phrases yourself. JPYC can be understood simply as “yen-denominated sponsorship”.

    See JPYC explained

  • Will steps record reliably on Android?

    iPhone connects through HealthKit and Android through Google Fit or Health Connect, both recording steps automatically. On Android, the exact setup differs slightly by device and OS version — please check the guide for the first time.
