Call your mother.

Twenty minutes on the phone with a parent or grandparent earns you a fragment of a real stock. They pick which one. You pick up. It is the only app that makes you feel better after using it.

Real stock tokens on Robinhood Chain. Call length verified by the app. Both of you say yes first.

The average adult calls a parent once every eleven days, for six minutes. Grandparents get less. This is unacceptable.

So we attached a stock to the phone call. Leveraging the full weight of the capital markets, Grandma Coin makes it financially irresponsible not to call.

Introducing Most-Favored-Grandchild rates, guaranteeing huge returns for families.

Fragments earned per callOne 20-minute call. Nana chose Coca-Cola.

BeforeYou called. Nothing happened.
AfterYou called. Coca-Cola happened.

This is the most impactful reset of the family phone call in the history of the family phone call. It puts more love in grandparents' weeks and, separately, a small amount of Coca-Cola in your wallet.

The proof is
in the calls

Every relative picks their own stock. Rates are set by the vault and by anyone in the family who tops it up. The only rule is twenty minutes, both of you on the line.

They opt in once.

Your relative installs nothing. They get one text with a link, tap yes, and pick a stock. Most pick the one they already talk about at dinner. That is the point.

How consent works
02

You call. Actually call.

The call is placed through Grandma Coin, which bridges both phones. That is how we know it happened and how long it lasted, without recording a word. Twenty continuous minutes, both lines open.

How a call is verified
03

Fragment lands. Both wallets.

A fraction of their pick moves from the vault to you and to them. Grandma now holds Coca-Cola on Robinhood Chain. She will not check it. She will mention it at bridge.

Frequently Asked Questions

For grandchildren
What is Grandma Coin?

A small incentive attached to a phone call. You call a parent or grandparent for twenty minutes, the app confirms the call happened, and a fragment of a real stock token lands in both of your wallets. The stock is their choice.

Is this financial advice?

No. It is a phone call. The fragments are real Robinhood Chain stock tokens and they go up and down. The call is guaranteed to improve your week. The token is not.

Can I put the phone down and walk away?

The app samples audio energy on both ends without recording anything. Twenty minutes of silence is not a call. Twenty minutes of Grandpa on the weather is, unfortunately, a call.

Where do the stocks come from?

A vault, funded at first by us and later by families who top up their own relatives' rates. Nothing is minted from nothing. A fragment only pays if the vault already holds it, and the vault balance is public. See the vault.

Does Grandma need a wallet?

One is created for her when she replies YES. She does not need to know that. If she asks, tell her it is like a savings account that Coca-Cola runs. That is close enough.

For parents and grandparents
Why is my grandchild suddenly calling every Sunday?

Some of it is the Coca-Cola. Most of it is you. Take the win.

Can I change my stock?

Yes, once a quarter, by replying to the text with a new ticker. Changing it mid-call is not supported and would be confusing for everyone.

Is it affiliated with Robinhood?

No. We build on their chain like anyone can. Not affiliated with Robinhood, Coca-Cola, Costco, or any grandmother.

Pick one. Any one.

Type their number. We handle the timer, the token, and the part where you feel good after.
