Keikai Spreadsheet supports both desktop and modern mobile browsers, you can easily access a Keikai-powered view from your tablet or smart phone.
Note that due to the nature of the spreadsheet, when designing the view for mobile users, you should consider to display a suitable (smaller) range that is easier for the users to navigate and use.
This inventory list example allows users to view the spreadsheet, edit the "shipped" column, and view the updated Stock-Current column in real-time. A conditional formatting rule is applied to the Stock-Current column, it displays an orange background when the stock is 50% and a red background when the stock is 20% of the previous month.
