App for realtime crypto/fiat value? (2023 Update)

Yes, there are several apps available that can help you track the value of your cryptocurrency holdings in fiat currency. Some popular choices include:

CoinTracking: This app allows you to track your trades and calculate your gains and losses in fiat currency. You can also generate reports for tax purposes and track your portfolio value in real-time.

CoinTracking Portfolio Manager: This is a web-based app that allows you to track your portfolio value in real-time, and calculate your gains and losses in fiat currency.

Delta: This app allows you to track your portfolio value in real-time, and supports over 8,000 cryptocurrencies. You can also view charts and market data, and set alerts for price changes.

CryptoCompare: This App gives you crypto coin value in fiat currency, also gives you an option to compare it with other coins, also gives you market analysis with charts and news.

There is (was?) also another quite nice one but it's unfortunately linked to the ill-fated FTX, so who knows what will become of the app, but here it is, Blockfolio. Blockfolio: This app allows you to track your portfolio value in real-time, and supports over 8,000 cryptocurrencies. You can also set alerts for price changes, and view charts and market data.

It's worth noting that these apps are not official or endorsed by the IRS, so it's important to do your own research and consult with a tax professional before using them for tax purposes.

Please make sure that you only use reputable and well-established apps, to avoid any fraud or security risks.
