Todoist is built to capture and organise everything you might do. Rymi is built to commit to the few things you will do today. The disagreement is about whether your list should be comprehensive or chosen - and it decides almost everything else about how the two apps feel.
Todoist rewards the capture habit: every stray thought goes in, filed and labelled, ready for a filter to surface later. That is a real strength, right up until the list stops being a day you do and becomes a system you maintain. Rymi is what you reach for when you have felt that shift and want the opposite.
For capturing a high volume of tasks quickly and having them on literally every platform, Todoist is the best there is. Capture is the fastest in the category, natural-language input is excellent, and projects, labels, filters, and priorities give you real power to organise. Sync is reliable on every device, including Linux and smartwatches, and it has recently added an AI voice-to-task feature. It is fast, reliable, and polished in ways a younger app is not.
The free plan is capped (around five projects); Pro is about $5 a month, roughly $60 a year after a recent increase. If you are cross-platform, or you capture hundreds of things and need power filters to keep them in order, Todoist is the correct choice - and Rymi is not competing for that job. It is worth saying clearly: Todoist is clean and fast, not bloated. Its depth is a feature.
Rymi drops the backlog for a daily commitment. There are no projects, labels, filters, or priorities to maintain - you capture freely, then each morning choose the few things that matter today and commit to them. It is free, native to Apple, keyboard-first, and needs no account. The point is not that Rymi manages your system better; it is that there is no system to manage, which for the right person is the entire relief.
The honest concession is straightforward. Todoist is more powerful, genuinely cross-platform, and far better for high-volume capture and complex filtering. If that is what your work needs, Rymi will feel like it is missing things - because it left them out on purpose. Rymi is a task tool for Apple that does less; that is the trade, stated up front.
