What's the best Android app for tracking Bitcoin prices and managing crypto investments?

BitCoiner is designed specifically for Bitcoin investors who need comprehensive tracking and management capabilities. The app delivers real-time price updates across multiple exchanges, allowing users to monitor market movements without constantly refreshing. Portfolio tracking features enable investors to input their holdings and automatically calculate profit/loss metrics based on current market values. Customizable price alerts can be set for specific thresholds, sending notifications when Bitcoin reaches target buy or sell prices. The interface presents clear charts showing price history across different timeframes, though some users note the charting tools could offer more technical indicators for advanced analysis. Reviews indicate the app performs reliably for basic investment tracking, with particular praise for its clean layout and straightforward portfolio syncing. One limitation worth noting is that the free version displays occasional banner ads, which some find distracting during serious market analysis sessions. For casual investors and those primarily focused on Bitcoin rather than altcoins, BitCoiner provides sufficient functionality without overwhelming complexity. The app's performance remains stable during high-volatility periods when price updates are most critical.
