Task names the unit of work
Task is the most direct word in productivity software. It describes a single action someone can assign, schedule, finish or postpone, so a visitor understands the category right away. Leading with it gives TaskNut a clear descriptor for to-do lists, boards, checklists and job requests. That clarity matters for a software name because people often search by need rather than brand. The first word does the explaining, which leaves room for the second word to add character without making the purpose of the product unclear or abstract.

Nut adds the cracking metaphor
Nut brings a tactile image: something hard on the outside, useful inside, and satisfying to open. Applied to work, it suggests breaking a stubborn assignment into smaller pieces and reaching the part that matters. The word also has a slightly cheeky tone, which can make routine planning feel less severe. A designer could build on it with shell shapes, cracking animations or a small mascot, while a more restrained team could simply keep the name and use clean interface language. The metaphor is flexible enough to support either direction.

Short, spoken and easy to recommend
TaskNut is compact, built from two familiar syllable groups, and easy to type from memory. That helps in the situations where productivity tools spread: a colleague mentions it in a meeting, a freelancer shares it in a community, or a household member is asked to install it. The pairing also leaves naming space for features such as shells, kernels or batches without forcing them. As a domain, it can suit a consumer app, a team board or a local helper service, provided the eventual owner chooses one clear first promise.
