A little structure. A lot more headspace. Shasks brings tasks and projects together on iPhone and Apple Watch. Capture a thought in natural language, make a plan, and reuse the projects you come back to. BUILD THE PLAN ONCE. USE IT AGAIN. Give a project its tasks, sections, and deadlines. Complete it when the work is done, or set it to repeat for your next weekly review, monthly checklist, or recurring process. Repeating projects carry their template tasks and sections into the next occurrence. TYPE THE TASK. SET THE DETAILS. Write “Call Alex tomorrow 3pm p1” and Quick Add recognizes the date, time, and priority. Add deadlines, choose an existing list with #, or an existing tag with @. See the recognized details before you save. You can also dictate a task instead of typing. REPEAT ON YOUR SCHEDULE. Choose a regular calendar schedule or repeat after completion. Every Friday and a week after you finish are different plans; Shasks supports both for tasks and projects. CAPTURE WHAT YOU FIND. Send links, text, photos, and files to Shasks from the iOS Share sheet. Keep notes, checklists, and attachments with the task so the details are there when you need them. MAKE ROOM FOR TODAY. • Focus with Today, Upcoming, Anytime, and Someday • Organize with areas, projects, headings, and tags • Set dates, deadlines, time reminders, and optional location reminders • View read-only calendar events alongside your tasks, or copy a task to Calendar • Access tasks locally and keep them synchronized through your account • Check Inbox and Today from Apple Watch Shasks has no advertising and does not track you across apps or websites.
