The new version To Do includes a refreshed look with new backgrounds. The app also includes a smart daily planner, lists that can be accessed from multiple devices, and integration with other Microsoft apps like Outlook, Microsoft Planner, and Cortana. It looks a lot like popular to-do app Wunderlist, and that’s not a coincidence. The company explicitly says it built the new To Do on the back of Wunderlist, and namedrops specific features it’s bringing over from its parent app. This might seem like a generally positive app update, but we know at least one person who isn’t happy about it: Wunderlist founder Christian Reber. Reber said on Twitter he’d be willing to buy Wunderlist back to avoid its shut-down, and to oblige the people who still use it. This isn’t the first time he’s made the offer — he simultaneously said he’d love to build a new version of Wunderlist and that he’s “happy to buy it back any day” back in March. But now that Wunderlist’s shut-down is closer than its ever been, his tweeted offers sound more serious.

— Christian Reber (@christianreber) September 6, 2019 When Microsoft revealed To-Do, it also frankly said it’d shut down Wunderlist eventually — though it also specified it wouldn’t do so until it’d integrated Wunderlist’s useful features: “Once we are confident that we have incorporated the best of Wunderlist into Microsoft To-Do, we will retire Wunderlist. While the name and icon may change, the team that brought you Wunderlist continues on.” Reber outlined what he’d do if he had Wunderlist back, including upping its utility for businesses and making it free for consumers.

— Christian Reber (@christianreber) September 8, 2019 Maybe I’m old-fashioned, but if I wanted to buy my product back, maybe I wouldn’t say I’d do everything possible to make it a viable competitor for the seller’s new product. Regardless, Reber’s tweet drew the attention of many who expressed their love for Wunderlist and supported his apparent bid. Microsoft, for its part, is encouraging Wunderlist users to migrate to the new To Do. Its press release also specifically thanks to “our Wunderlist and To Do fans.”
