Educational ETF screener for iPhone
Understand any ETF before you buy.
Answer a few plain-English questions. See the funds that fit you — and exactly why. Open up what's actually inside, all on your device.
The problem
You keep hearing "just buy an index fund." But which one? And what's even in it?
There are thousands of ETFs and a wall of jargon — expense ratio, AUM, tracking error, distribution yield. So most people do one of three things: buy something blind and hope, freeze and miss out, or feel too embarrassed to ask.
You don't need someone to tell you what to buy. You need to actually understand what you're looking at — what's inside it, whether it fits you, and what the numbers mean — so the choice feels like yours. That's the whole reason WhatETF exists.

What WhatETF reveals
Everything WhatETF reveals about a fund — so you can decide with your eyes open.

Matches that fit you, not a sales list.
Answer a few questions and WhatETF shows funds that fit the risk profile you set — never a "hot picks" list, never a nudge to buy. Educational matches, built around you.

See exactly why. No mystery rankings.
Every match opens a factor-by-factor breakdown — Category fit, Risk match, Expense ratio, Size & liquidity, Diversification, Goal alignment — that adds up to the score you see. Nothing hidden.

Open the black box.
See what's actually inside a fund — the real holdings, not a vague label. Finally know what you'd own.

"What if I'd invested?"
Pick a fund, an amount, and a date, and see how that amount could have grown over time — clearly illustrative, for learning.
Past performance does not guarantee future results.

Weigh funds side by side.
Line two or three funds up in one view — fit score, expense ratio, size, and category, row by row — so the trade-offs are obvious.
See the whole story.
Multi-year price history laid out clearly — watch how a fund has actually behaved over time.
Keep an eye on what you're learning about.
Save funds to a watchlist and see how they moved at end of day.
Finally understand the jargon.
A Learn hub and searchable glossary, plus tap-to-define for the terms that trip everyone up.

No black box. You can check our math by hand.
Answer a few questions
Reads your comfort and capacity for risk, combined conservatively.

A 0–100 score: a plain weighted sum of six named factors, on-device, instant.
See the why — and dig in
Factor reasoning, then holdings, history, and the simulator whenever you want.
We publish the recipe.
The full methodology lives inside the app — the exact factors, their real weights, and the rules (missing a number → drop that factor and rescale; never make a value up). No human adviser, no broker, no hidden ranking. Transparent, reproducible logic you can audit.
Straight about the data.
Prices and statistics are end-of-day, not live tick-by-tick — and the "data as of" date is shown throughout. Holdings are factual.
How it compares
Built for understanding, not for trading.

WhatETF isn't a brokerage and isn't an adviser. Nothing to trade, no account to open, no one nudging you. A calm place to learn — the rest is up to you.
Questions
A few honest answers.
Is this financial advice?
No. It's an educational tool. It doesn't recommend buying or selling anything, isn't a broker or adviser, and doesn't consider your full situation. Matches and model mixes are illustrative, for learning.
Is the data live?
It's end-of-day, not real-time — and we show the "as of" date throughout.
Is my data private?
Yes — no account or sign-up; your profile and saved funds stay on your iPhone. When fetching market data, only the fund symbol and an anonymous random install ID are sent; no personal data, never used to track you across apps.
What can WhatETF do?
Build your risk profile and surface matching funds, show exactly why each one fits factor by factor, open up the real holdings inside a fund, chart multi-year price history, run the "what if I'd invested?" simulator, compare funds side by side, keep a watchlist, and explain the jargon in a Learn hub and glossary.
