PocketBacktest

How would that portfolio actually have done?

Type the tickers, set the weights, pick a period, tap Run Backtest. You get a clean growth chart and the numbers that matter. In about ten seconds, with no account and no spreadsheet.

BUILD IT YOUR WAY • Save multiple portfolios of stocks, ETFs, and crypto • Start from a preset - 60/40 Balanced, All Weather, Three-Fund, Total Nasdaq, Crypto Blend and more • Split weights evenly with one tap, or type them to the decimal • Duplicate a portfolio to try a variation without losing the original • Swipe to delete; each portfolio keeps the colour it uses on the chart

TEST IT PROPERLY • Periods from 1 week to 5 years, YTD, or the full available history • Rebalancing: Buy & Hold, Monthly, Quarterly, or Annually • Add recurring contributions - daily, weekly, monthly, quarterly or yearly • Set your own risk-free rate for the risk figures

THE NUMBERS • Total return, CAGR, and ending balance • Money-weighted return (MWRR) once you are adding contributions • Maximum drawdown - the worst peak-to-trough fall along the way • Volatility, Sharpe, Sortino, Calmar, and beta • Contributions are excluded from the return maths, so money you paid in is never counted as growth

READ THE CHART • Compare every portfolio on one chart, side by side • Drag to inspect any single day; press and hold, then drag, to measure a range • Turn the phone sideways for a full-screen chart • Optional log scale, or start everything at 100 to compare shape rather than dollars • Export a run as CSV and a chart image, zipped and ready to share

MADE TO LIVE ON YOUR PHONE • Ten themes, each with a genuine light and dark version that follows your System setting • Portfolio Pulse widget keeps your last run on the home screen • Ask Siri: "Run a backtest in PocketBacktest" • Full Dynamic Type, VoiceOver labels, and Reduce Motion support • Prices are cached, so recent runs still work with a weak connection
