No external productivity tools are designed with your process in mind. Instead of changing your process to fit some tool, change the tools to work around your process.
With our executive app processes, instead of building an app that works on every device with full-featured branding and design, we're building an app for your device(s) with the built-in material designs provided by Apple and Google. You may be surprised what powerful tools can be built within a reasonable budget when you take the app stores and 20 year old devices off table.
3rd-party tools collect data for a variety of reasons. At best they use it in aggregate to improve their features and services. At worst they use it to develop revenue channels without your permission. Your custom executive app can be locked down in a more secure way than any 3rd party tool.
