Best Investing Apps for Kids in 2026: An Honest Comparison

Search "best investing app for kids" and you get a wall of names — Greenlight, GoHenry, Acorns Early, Stockpile, Fidelity Youth, UNest. The problem is that they are not really the same kind of thing, so ranking them one-to-five is the wrong question. The right question is: which category fits what you actually want? Once you know that, the pick is easy.

Here are the four categories these apps fall into, what each is genuinely good at, and how to choose — without a spec table that will be out of date by the time you read it. (Prices and features change constantly; always confirm the current details on each provider's own site before you sign up.)

Category 1 — Debit card + allowance apps

Greenlight is the best-known here: a kids' debit card with allowance and chore automation, built to teach spending and saving habits — money in, money out, a little set aside. It has added a feature that lets kids buy stocks with a parent's approval, so a curious teen can get a first taste of investing. (GoHenry, the other big name in this category, was rebranded to Acorns Early in the U.S. in 2024, so in the States it now lives in the next category.) If you are weighing Greenlight specifically, see Greenlight alternatives for investing.

Best if: your main goal is day-to-day money skills — an allowance that runs itself, a card with guardrails, chores tracking — with investing as a nice-to-have rather than the point.

Category 2 — Managed (robo) custodial accounts

Acorns Early and UNest open a real custodial account (a UTMA/UGMA) for your child and manage the investing for you — you set contributions, and a diversified portfolio is chosen and rebalanced automatically. (In the U.S., Acorns Early is also where the former GoHenry's debit card and chores features now live, after Acorns rebranded it in 2024.) It is the hands-off way to actually invest for a kid.

Best if: you want money genuinely invested for the long term but do not want to pick funds yourself — automation over control.

Category 3 — Kid and teen brokerage accounts

Stockpile, Fidelity Youth, and Schwab's teen account are real brokerage accounts where an older kid or teen can buy and hold investments themselves (with a parent attached). Stockpile leans into buying and gifting individual stocks in a kid-friendly way; the major brokers offer teen accounts with their full investing toolset.

Best if: you have an older kid or teen ready to make real, self-directed trades and learn by doing — see the best custodial accounts for where to open one.

Category 4 — Kids' investment dashboards

MemoryBank is a different kind of tool: it does not open or hold accounts at all. It connects — read-only — to the real accounts your child already has, across different institutions, and shows them in one dashboard built for a kid to actually understand. A UTMA at one broker, a 529 at the state plan, a custodial Roth somewhere else — all in a single view your child can watch grow.

The part that sets it apart: a wall of numbers still needs a translator, so MemoryBank has Penny, a built-in AI money mentor who explains what your child owns — and the money terms behind it — in language matched to their age. A five-year-old, an eight-year-old, and a teenager each get an answer pitched at their level, tied to their own real holdings. That is the difference between a kid seeing an account and a kid understanding it.

Best if: you already have accounts open (anywhere) and what you actually want is for your kid to see and learn from them — the education layer, not another place to open an account. Here is how to see all your kid's investment accounts in one place.

MemoryBank is a display and education tool, not a broker, and earns nothing from which accounts you open or which of these apps you choose — which is why this comparison can be straight with you.

So which is "best"?

There is no single winner, because they answer different questions:

• Want a debit card + allowance? A spending app (Greenlight, GoHenry).
• Want hands-off investing? A managed custodial account (Acorns Early, UNest).
• Want a teen to trade themselves? A brokerage (Stockpile, Fidelity Youth, Schwab).
• Want your kid to watch and learn from the accounts they already have? A dashboard (MemoryBank).

Many families end up using more than one — say, a custodial account for the actual investing and a dashboard so the kid can follow it. They are not competitors so much as different layers of the same goal.

Frequently asked questions

What's the best investing app for kids?

It depends on the goal, because these apps are different categories. For a debit card and allowance, Greenlight (GoHenry became Acorns Early in the U.S. in 2024); for hands-off investing, a managed custodial account like Acorns Early or UNest; for a teen trading themselves, a brokerage like Stockpile or Fidelity Youth; and to let a kid watch and learn from accounts they already have, a dashboard like MemoryBank. There's no single winner — pick the category that matches what you want.

Is Greenlight an investing app?

Primarily, Greenlight is a kids' debit card with allowance and chore features. It has added the ability for kids to buy stocks with a parent's approval, so it includes some investing — but its core strength is teaching everyday spending and saving, not long-term investing.

What's the difference between an investing app and a dashboard like MemoryBank?

An investing app (or brokerage) is where the account lives and trades happen. A dashboard like MemoryBank doesn't hold money or place trades — it connects read-only to the real accounts your child already has, across institutions, and shows them in one kid-friendly view so the child can watch and learn. Many families use both.

Can one app do everything — debit card, investing, and education?

Not really, and that's fine. These tools specialize: spending apps do allowances and cards well, custodial and brokerage accounts do investing, and dashboards do the see-and-learn layer. Trying to force one to do all three usually means it does none of them especially well. Most families combine two.

Do these apps' prices and features change?

Yes, frequently — which is why this guide compares them by category and approach rather than by price or a feature checklist that would go stale. Before signing up for any of them, confirm the current pricing and features on that provider's own site.

What to do this week

1. Name your real goal: a card and allowance, hands-off investing, a teen trading, or a kid watching accounts grow.
2. Pick the category that matches — not the app with the most features.
3. If the accounts already exist, connect them in MemoryBank so your kid can actually follow the money, whichever provider holds it.
