Eeto is a linear calendar that uses colored milestones to help you easily visualize your events on a timeline. Think of milestones as a short or long term goal, a company deadline, a product release, an anniversary, your prom night, or a wedding. Milestone events are big in importance, but small in scale. Using Eeto’s linear timeline design, you’ll quickly understand Eeto’s ability to put events and deadlines into perspective. Most calendars show months in blocks, weeks in loops, or days in vertical views. But like most sane humans, Eeto views time as a straight path, forward and backward. We are a small team, and Eeto is a work in progress. We’d love to hear your suggestions for future releases. For now, you can create events (including recurring) and get a feel for the user interface. In the future, we hope to bring you features like sharing, print, import, custom colors, and plug into other apps. We hope you enjoy this project and please share your thoughts!
