Almost everything worth knowing about an ETF is free: expense ratios, holdings, overlap, distributions. So what do paid tiers sell? Depth, workflow, comfort, not answers.

- Never pay for data you can get free; no paid app knows which ETF performs best - Consider paying only for weekly-used workflow: cross-brokerage aggregation, serious alert customization - The most expensive subscription is the one you pay for and never open - Screening is a five-minute job a few times a year; save the subscription money, it compounds too - Free screener for most people, paid only if the workflow earns its keep

Run the free comparison first: Overlap ($4.99 one-time) covers 108 ETFs, fees, overlap, and returns, one screen.
