Stockfly
Tracks your actual investment portfolio across brokers and currencies, and tells you your real return — not the misleading number your broker shows you.

Description
Most brokerage apps show you a return percentage that doesn't account for when you added or withdrew money, which makes it look like you're doing better or worse than you actually are. Stockfly fixes that by calculating your money-weighted return (the number that actually reflects your timing of deposits and withdrawals), tracking dividends with tax already factored in, and pulling all your holdings — even across different brokers and currencies — into one clear view without the jargon.
Stockfly is broker-neutral: instead of connecting to a specific brokerage API, it lets you import your holdings from a single spreadsheet and then tracks live pricing, per-holding and portfolio-wide IRR, dividend withholding tax, and performance versus market indices. It includes plain-language stock insights on trends and valuations, a what-if planner for modeling target allocations, and exportable tax summaries in PDF or Excel. The product is built by a solo founder (Sedat Kaan Gozum) with an explicit no-ads, no-jargon design philosophy, and authentication is handled via Google Sign-in.
💬 Our review
The short version: if you've ever looked at your brokerage's "return" number and suspected it doesn't actually reflect what you put in and took out, Stockfly's money-weighted IRR calculation is the fix — it's a genuinely more honest number than what most retail platforms show by default.
Compared to free built-in broker dashboards, Stockfly's value is being broker-neutral and multi-currency, so it works whether your holdings are spread across two or five platforms — something no single broker's app can do for you. Against dedicated portfolio trackers like Kubera ($150/yr+) or Sharesight (from $15/mo for full features), Stockfly is considerably cheaper at $4.99/mo or $49/yr, and its free tier already includes unlimited holdings, which is generous. The tradeoffs: it's a solo-developer product (continuity risk if the founder moves on), spreadsheet import is manual rather than live brokerage sync, and tax exports are aimed at simple withholding scenarios rather than full multi-jurisdiction filing. For a hobbyist or serious individual investor tracking a multi-broker portfolio, it's a fair deal; for someone needing audited, accountant-grade tax output, it's not a replacement for Sharesight or a real tax tool.
