How can we help?

An educational iPhone app that helps you understand ETFs. Answer a few plain-English questions, see funds that fit your risk profile and exactly why, open up what's actually inside them, and learn the jargon.

No. Purely educational. It never tells you to buy or sell anything, isn't a broker or adviser, and doesn't consider your personal finances. Matches and model mixes are illustrative, for learning. The choice is always yours.

It scored well against the risk profile you built. Open any match to see the breakdown, Category fit, Risk match, Expense ratio, Size & liquidity, Diversification, Goal alignment, each contributing to a score out of 100. "Match" means "fits your stated profile," not "you should buy this."

No. It's end-of-day, not streaming or tick-by-tick, and we show the "data as of" date throughout. Offline, you'll see your last-synced figures. Portfolio and simulator values are estimated from those end-of-day prices.

103 US-listed ETFs from a curated dataset, plus end-of-day prices, multi-year history, and real holdings via our market-data service. Holdings are factual, we don't fabricate them.

Add the funds you hold, with units and average cost, or let a smart end-of-day price prefill the figures. WhatETF then shows an estimated value and allocation, a value-over-time view, a returns breakdown (including a money-weighted XIRR figure), a transaction ledger, and an illustrative DCA estimate. It's read-only and educational: it never connects to a brokerage, places no trades, and never tells you to buy, sell, or rebalance. Every value is estimated from end-of-day prices and stamped "as of" a date. It lives only on your iPhone.

It covers the whole ETF picture: a plain-English risk questionnaire and matches, the factor-by-factor "why it fits" breakdown, live end-of-day prices, full fund holdings and multi-year price history, comparing funds side by side, a watchlist, the "what if I'd invested?" simulator, a read-only Portfolio that tracks your estimated value over time, and a full Learn hub and glossary. No account, nothing to sign up for.

Data can have errors or delays, and past performance never guarantees future results. Always verify anything important.

Very. No account or sign-up; your profile and saved funds stay on your iPhone. See the Privacy Policy.

No, and you can't create one. Just download and start; your profile lives on your iPhone.

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, track the funds you hold in a read-only Portfolio with an estimated value and allocation, run the "what if I'd invested?" simulator, compare funds side by side, keep a watchlist with end-of-day changes, and explain the jargon in a Learn hub and glossary.

Supports VoiceOver, Dynamic Type, strong contrast, and Reduce Motion, every chart and risk meter has a text equivalent. Tell us if anything's hard to use.
