Your portfolio might include any combination of financial assets: stocks, bonds and mutual funds, to ETFs, 401(k)s and IRAs. Keeping track of all these assets can be a challenging, if not a daunting, task. Unless you’re happy just winging it (and you should not be happy just winging it), it’s important to know what’s going on with all your investments, all the time—not just once a year when you get your tax forms in the mail.

Fortunately, there are a number of mobile apps that offer up-to-the-minute information on all your investments in one tidy place. Let's take a look at four popular portfolio management apps that track your investments so you know exactly where you stand. (For more, see: Top 10 Biggest Mobile Apps of 2015.)

Personal Capital Finance

Platform: iOS, Android, Amazon
Cost: Free

Personal Capital integrates with more than 10,000 financial institutions, among them Fidelity, Charles Schwab Corp. (SCHW), PayPal and Wells Fargo & Co. (WFC). Sync virtually any investment account, including retirement and taxable accounts, and then track performance, allocation and fees with easy-to-read graphs and charts. Track investments by account, asset class or individual security. The Personal Capital “You Index” tracks your holdings and measures their performance against major market indices so you can see how you’re doing across your stock, cash, ETF and mutual fund positions. The Portfolio Checkup feature determines whether you can save money on mutual fund fees, and the Asset Allocation Review uncovers opportunities for diversification. Work with a personal wealth management advisor to discuss your investment needs via FaceTime, email or phone. Bank-level security uses a two-step remote authentication process.

SigFig Wealth Management

Platform: iOS, Android
Cost: Free

Use the investment company SigFig's Wealth Management app to track all your investment accounts for free, or let SigFig invest for you in a low-cost automated ETF portfolio. SigFig automatically pulls your investment accounts from more than 80 U.S.-based brokerages into a single dashboard to give you a real-time view of every stock, mutual fund, ETF and option you own, plus it snapshots your 401(k) plan and IRAs. You’ll get weekly email summaries of account performance, news that impacts your portfolio, and alerts that focus on your top gainers and losers. The app automatically analyzes your portfolio to find hidden fees and overexposure to a single stock/industry and risk levels. For a fee, users can optimize their returns with automated investing; SigFig will optimize your portfolio and provide daily monitoring to keep it on track with rebalancing, dividend reinvestment and tax-efficient strategies. The app's 256-bit SSL encryption provides the same level of security used by banks and brokerages.

Ticker: Stocks Portfolio Manager

Platform: iOS, Android
Cost: Free

The Ticker app lets you manage multiple stock portfolios—think growth, technology and retirement portfolios—from one dashboard. Colorful charts, graphs and detailed analytics show real-time account values, profit/loss, daily profit/loss, allocation money-weighted rate of return (MWRR) and time-weighted rate of return (TWRR), plus symbol-relevant news. Manually enter trade information for stocks, currency pairs (e.g., EUR/USD, USD/JPY, GBP/USD and AUD/USD), mutual funds and ETFs, including dividends, splits, buy/sell orders, ticker symbol, trade size, price, date and brokerage fees. Keep track of stocks with multiple watch lists, and create alerts to notify you if a stock trades above or below a trigger level you set, based on price, volume and percent changes.

USA TODAY MONEY Portfolio Tracker

Platform: iOS, Android
Cost: Free

Use the USA TODAY Money Portfolio Tracker app to see all your investment accounts in one place, including stocks, mutual funds, ETFs, 401(k)s and IRAs. The app, powered by SigFig, syncs with many U.S.-based brokerages, including E*Trade, Fidelity, Scottrade and Vanguard. Track account performance, view real-time quotes and news, and analyze your asset allocation, dividend yields and risk level. The app uses 256-bit SSL encryption for bank-level security, and sensitive information such as account numbers remains unidentifiable. Your portfolio is password-protected, and all information is read only, so nobody else can monitor your money.

The Bottom Line

Portfolio management apps make keeping track of your investments pretty easy—and something you can do from almost anywhere at any time. Some apps sync with your existing accounts while others require you to manually enter information on your holdings. In either case, such apps provide up-to-the-minute information so you know where you stand now as well as tools to help you get where you want to be in the future.
