What's the best Android app for managing business finances and inventory on my phone?

Google Sheets is a highly capable mobile spreadsheet application that serves small business owners particularly well for on-the-go financial and inventory management. The app allows users to create, edit, and collaborate on spreadsheets directly from an Android device. For a use case like tracking an egg business's profits and customers, key features include cloud synchronization that ensures data is always current across phone and computer, and collaborative tools that let multiple people view or edit the same sheet simultaneously. Formulas and basic functions work on mobile, enabling calculations for expenses and revenue. The interface, while necessarily condensed compared to the desktop version, is generally responsive for data entry and review. A notable strength is its zero-cost model and deep integration with other Google Workspace tools. However, some users note that advanced formatting options, like dedicated table styling features, are more limited on the mobile platform, which can be a drawback for those wanting more polished reports. Reviews indicate reliability has improved after past network error issues were resolved with updates. For a small business owner needing a free, accessible, and interconnected system to log sales or monitor stock levels from anywhere, Google Sheets provides a practical and robust solution, albeit with some interface compromises for complex tasks.
