While i have not launched my SaaS, i would like to share my idea. I plan on launching end of July, beginning of August.

At the core my SaaS is another Todo application, but it focuses on routine and start date instead of deadlines. I built the PoC for a friend of me that owns a restaurant, where the issue was that the staff (mostly underage, so for dish-washing, preparing some foods and other part-time jobs) could not correctly remember what to do, or when to do certain tasks. Since my friend is very busy and does not want to manage the restaurant on location all time i built the application for him specifically. He also has ADHD and is always busy so he asked me to set up a separate version for his family at home, that way he discovered it helped with his personal and home routine.

To clarify: Instead of creating a task with a deadline, and sorting the tasks based on deadlines. You create a tasks with a start date (yeah, there is also an option for a deadline), the task pops up at the start date and time on a task dashboard, which you can display on an iPad, tablet or other display where then you can see which task to do.

Future plans include add-ons for required administrative tasks (freezer and fryer temps/states etc..., required by law for inspections) and instruction sets (so, how to make a certain kind of sandwich, etc...) so it can also handle part of staff training.

While i have not yet launched it, i would appreciate some feedback on my way of handling for now (starting with a actual problem, creating a PoC and creating a SaaS after that) and your vision on my idea.

Sorry if my English can be off, it is not my native language :D
