It is easy to build apps if your data is already in Smartsheet.
Use your Smartsheet account to sign into AppSheet. You can then build mobile apps using any of your data sheets. In fact, AppSheet is already aware of some Smartsheet-specific column types like Harvey Ball and Color. All AppSheet functionality works seamlessly with Smartsheet data.
If you are a business customer of Smartsheet, the solutions team at Smartsheet can also help you with your AppSheet integration.
