We use checklists in our day job, so it's very familiar! The ability to add notes or comments helps us keep track of what we've done today as well as where things are at with all projects that have been started but not yet completed (e.g., "Incomplete Project"). I don't particularly like how you can only do one checklist per task/project if there were multiple steps involved - this makes managing them difficult when they're more than two items long. There could be an option within each step item to create subcharts instead of having separate ones. This would make it easier to manage several lists together without going back & forth between tabs. If you need something simple, try using Google Keep first because its simplicity will likely appeal most to people who aren't used to project planning tools such as Microsoft Excel etc. Keeping track of ongoing.
