FlashFi vs Portseido: Two Multi-Currency Trackers for Global Investors

Disclosure: FlashFi is a competitor to the products mentioned.

Disclosure: FlashFi is a competitor to Portseido. This is our honest assessment based on publicly available information.

TL;DR¶

Choose Portseido if you want a dedicated investment tracker with strong performance analytics (TWR/MWR), dividend tracking, and broad exchange coverage across 70+ markets. It has a free tier, a native mobile app, and is built specifically for international stock investors.

Choose FlashFi if you want investment tracking plus personal finance management — cash accounts, debt, savings — in one multi-currency app. FlashFi is designed for the full financial picture, not just your portfolio.

Quick Comparison¶

Pricing Breakdown¶

Portseido offers three tiers:

• Free — $0/month. 1 portfolio, up to 50 transactions. Full access to reports and analytics. No ads.
• Plus — $8/month (billed annually). 1 portfolio, up to 200 transactions. Priority email support.
• Pro — $12/month (billed annually). Multiple portfolios, unlimited transactions. All features unlocked.

Portseido also offers a 14-day free trial of Pro with no credit card required.

FlashFi has two tiers:

• Operator — $12/month ($144/year). Full investment tracking, personal finance, multi-currency.
• Apex — $39/month ($468/year). Everything in Operator plus advanced analytics.

At the entry level, Portseido wins clearly: it has a free tier that is genuinely usable for someone with a small portfolio. Even the Plus plan at $8/month undercuts FlashFi’s $12/month. At the full-featured tier, both Pro and Operator cost $12/month — but Portseido includes dividend tracking and performance analytics that FlashFi does not yet match.

The honest assessment: if investment tracking is all you need, Portseido offers more for less.

Exchange and Asset Coverage¶

Portseido supports over 70 stock exchanges worldwide, more than 20,000 ETFs, and cryptocurrency. FlashFi uses Tiingo for market data, which covers major US exchanges comprehensively and has reasonable international coverage, but has known gaps in some European and Asian markets.

If you trade on smaller international exchanges, Portseido’s coverage is broader. Check whether your specific exchange is supported before choosing either platform.

Performance Analytics¶

This is where Portseido differentiates itself from most consumer portfolio trackers:

• Time-Weighted Return (TWR) — Measures performance independent of cash flows. The standard for benchmarking.
• Money-Weighted Return (MWR) — Factors in timing and size of contributions. Your actual personal return.
• Benchmark comparison — Compare returns against market indices.
• Trade analysis — Evaluate the impact of individual trades on overall performance.
• FX impact separation — Automatically splits foreign exchange gains from investment gains.

FlashFi currently shows portfolio value over time, unrealized P&L per holding, allocation breakdowns, and net worth history. Useful for understanding what you own and how your net worth is trending, but Portseido is more rigorous about measuring how well your investments are performing.

Dividend Tracking¶

Portseido has dedicated dividend features that FlashFi does not offer: global dividend income tracking, yield and payout ratio monitoring, income projections, and withholding tax tracking across US, UK, Europe, Canada, Singapore, Australia, Brazil, South Korea, and more.

If dividend income is a meaningful part of your strategy — whether you are building a dividend growth portfolio or relying on investment income abroad — Portseido is the stronger choice. FlashFi does not have purpose-built dividend analytics.

Personal Finance¶

Portseido is an investment tracker. It does that job well, but it stops at the edge of your portfolio. It does not track bank accounts, savings, or debts.

FlashFi includes personal finance tools alongside investments:

• Cash accounts — Track bank accounts across multiple currencies, converted to your home currency.
• Debt tracking — Credit cards, loans, mortgages. Balances and interest rates in any currency.
• Savings tracking — Emergency funds, travel funds, goal-based savings across currencies.
• Net worth — Combines investments, cash, savings, and debt into a single figure with historical charts.

For a digital nomad with bank accounts in three countries, a credit card in USD, savings in EUR, and investments in multiple currencies, FlashFi shows the complete picture in one place.

Mobile and Broker Integration¶

Portseido offers native iOS and Android apps alongside its web platform, plus CSV imports from over 70 brokerages (Interactive Brokers, DEGIRO, Trading 212, Fidelity, Charles Schwab, and others). If you have an established portfolio with hundreds of transactions, importing via CSV saves significant time.

FlashFi is a web app designed mobile-first. It works well in phone browsers but is not a native app. All holdings are added manually — you search for a ticker, enter shares and cost basis, and pricing updates automatically from there.

Where Portseido Wins¶

• Price — Free tier is genuinely usable. Paid plans are cheaper or equal to FlashFi.
• Performance analytics — TWR, MWR, benchmark comparison, trade analysis, FX impact separation.
• Dividend tracking — Comprehensive dividend income tracking, projections, and withholding tax monitoring.
• Exchange coverage — 70+ stock exchanges and 20,000+ ETFs worldwide.
• Broker imports — CSV imports from 70+ brokerages. Much faster than manual entry.
• Native mobile apps — iOS and Android apps, not just a mobile website.
• FIRE calculator — Built-in financial independence planning tool.

Where FlashFi Wins¶

• Personal finance — Cash accounts, debt tracking, and savings across currencies. One app for your full financial picture, not just investments.
• Net worth tracking — Combines investments, cash, savings, and debt into one number. Portseido only tracks the investment side.
• Multi-currency as a foundation — Every screen is designed around managing money across currencies. Cash accounts, debts, and savings are all multi-currency, not just holdings.
• Simpler interface — Fewer features means less complexity. If you do not need TWR/MWR analysis, FlashFi’s dashboard is cleaner and faster to scan.
• No transaction limits — Both FlashFi tiers include unlimited transactions. Portseido’s free and Plus tiers cap transactions at 50 and 200 respectively.

Who Should Choose Portseido¶

Portseido is the right choice if you:

• Want a dedicated investment tracker with serious performance analytics (TWR/MWR)
• Rely on dividend income and need detailed dividend tracking and projections
• Trade on international exchanges and need broad market coverage
• Want to import transaction history from your brokerages via CSV
• Prefer a native mobile app over a mobile website
• Want a free tier to start with, or need to keep costs low
• Focus on investment performance rather than overall personal finance

Who Should Choose FlashFi¶

FlashFi is the right choice if you:

• Are a digital nomad or expat who needs to track both investments and personal finances in one app
• Have bank accounts, debts, and savings in multiple currencies that you want alongside your portfolio
• Care more about your total net worth than granular investment performance metrics
• Want a clean, simple interface without the complexity of TWR/MWR dashboards
• Need unlimited transactions from day one without worrying about tier limits
