Delta

Delta, now branded as Delta by eToro, is a multi-asset investment tracking app that allows individual investors to monitor portfolios of cryptocurrencies, stocks, ETFs, forex, bonds, commodities, and other asset classes from a single interface. The app is read-only and cannot execute trades or move funds.

Delta was founded in 2017 in Ghent, Belgium, by Lorenz Bogaert under the company Opus Labs NV. eToro acquired Delta in November 2019. The app supports over 10,000 crypto assets across more than 300 exchanges, and connects to major stock brokerages including Interactive Brokers, Robinhood, and Fidelity. It is available on iOS, Android, Windows, and Mac. A free tier covers basic portfolio tracking; the paid Delta PRO subscription adds unlimited account connections, real-time price updates, advanced portfolio analytics, and AI-powered market summaries.

Key features include customizable price alerts, on-chain analytics for crypto holdings, diversity analysis showing sector and geographic allocation, and an “insights” module that provides context on price movements. The app syncs portfolio data across devices and supports connection of crypto wallets and exchange accounts directly.
