I need software like Todoist or Microsoft To Do that 1) I can buy and not rent, and 2) I don't have to have an existing account with someone to use (like Microsoft To Do will only work with a Microsoft account). I just want an app I can buy once and not have it tied to an email account. I've found a lot of apps like Todoist that want you to keep paying them money month after month, year after year, so a $4/month app turns out to cost hundreds of dollars over the long run. I'll pay $50 for something like ToDoist once, not year after year after year. No thanks.
