Phaseboard
Read full descriptionHide full description
For the moments when products, prototypes, side projects, and late-night ideas are all alive at once. Phaseboard is a quiet, beautiful place to keep them, with each one's current stage, progress, and the one thing to do next. Every project breaks down the same way. From outermost to innermost: project, stage, task, subtask. Statuses roll up automatically as you check things off, so the dashboard always shows which projects deserve your time today. Projects now support deadlines, with a countdown on Home and on the project page. The Calendar page lists every deadline and task due date by month. Three new free widgets show the calendar and upcoming deadlines on the Home Screen. Two styles are available: Quiet, with soft lines and plenty of room, and Classic, the original engineering-manual look. Switch between them any time from the side menu. Phaseboard is built natively for iPhone, iPad, and Mac. Your projects sync privately through your own iCloud, with full offline support. Home Screen widgets, Lock Screen views, and a Mac menu bar tile keep what you're working on always in sight. Available in English, Simplified Chinese, and Japanese.
