What's the best iOS app for tracking daily sales and generating simple reports for a mobile service business?

Square Point of Sale (POS) is widely regarded as a top solution for service-based businesses like mobile mechanics, personal trainers, or consultants who need to track transactions and understand their revenue on the go. The app’s primary strength for this use case is its real-time sales dashboard, which updates instantly with every cash, card, or contactless payment processed through a smartphone or paired card reader. Users can view daily, weekly, or custom-date-range summaries directly on their iPhone, showing gross sales, net totals after fees, and a list of all transactions. For deeper insight, the app allows filtering sales by item or service type, which is useful for identifying which offerings are most profitable. The reporting function enables exporting data as CSV files for further analysis in spreadsheet software, addressing a common need for basic monthly accounting. While the in-app analytics are comprehensive for day-to-day operations, some user feedback notes that creating complex year-over-year comparative charts still requires manual work outside the app, as one review highlighted a desire for easier historical comparisons. Nevertheless, the combination of seamless payment processing tied directly to automated record-keeping eliminates manual data entry errors and saves significant time for sole proprietors. The ability to issue digital receipts that are stored within both the seller’s and customer’s transaction history also simplifies tracking and customer service inquiries. For a mobile service professional, this integration means an entire point-of-sale system, payment processor, and basic bookkeeping tool resides in one app, streamlining operations significantly.
