Yes — you can use ExpenseBot on your phone. ExpenseBot works on iPhone, iPad and Android as a mobile web app. Open ExpenseBot in your phone's browser to capture receipts and use your account. You do not need the Google Sheets app to use ExpenseBot.
Want an ExpenseBot icon on your Home Screen? In ExpenseBot, open Settings → Install ExpenseBot → Add to Home Screen and follow the instructions for your browser. On iPhone or iPad, you can also open ExpenseBot in Safari and choose Share → Add to Home Screen. Then open the ExpenseBot icon. If the install card is absent because ExpenseBot is already installed, use the existing icon or continue in your browser.
The Google Sheets app is optional for directly viewing or editing the underlying spreadsheet. It is not a replacement for ExpenseBot's mobile interface. For spreadsheet-specific instructions, see viewing and editing your spreadsheet on mobile.
En español: Sí, puedes usar ExpenseBot en tu celular desde el navegador. Para añadir su icono, abre Settings → Install ExpenseBot → Add to Home Screen. Google Sheets es opcional para editar directamente la hoja; no es necesario para usar ExpenseBot.
