Your day only has 24 hours. It is a beaker with an absolutely fixed capacity, not an infinitely stretchable to-do list. Time Vessel provides a brand-new "time physics" perspective. We abandoned complex settings and anxiety-inducing deadlines, visualizing all schedules and external disturbances into the three most intuitive physical materials, allowing you to truly "see" and "touch" the volume of time: Free Liquid: Can be freely manipulated and dragged, but just like real hydraulic principles, it cannot be compressed. Represents tasks that you can arrange flexibly but must guarantee the full duration of focus. Elastic Jelly: Excellent extensibility. It can be squeezed and have its compression rate set, but cannot be shifted freely. Represents daily routines with flexible time boundaries that can be adapted at any time. Solid Glass: Hard and its position is absolutely locked. It cannot be compressed, nor can it be shifted by other tasks. Represents the sacred and inviolable fixed schedules in your life (e.g., important meetings, force majeure, deep sleep). Whether you use it to plan your day in advance or just to record the "occupation" of today by completed tasks, Time Vessel allows you to intuitively perceive: when solid glass and free liquid fill the beaker, there is no extra space left for today. It gently reminds you through physical laws—when the cup is full, it's time to rest. Here, there are no weekly plans, no monthly views, and no automatically generated repeating templates. Because life cannot be accurately predicted, and anxiety often comes from excessive attempts to control the future. Every day is a brand-new day. No red overdue warnings, no mountains of guilt. With a simple swipe or long press, you can truly feel the physical feedback as tasks are completed and dissipated. Whether you swipe away the last arrangement of the day, or choose "Clear All" in the menu at any time to start fresh—no matter how today went, when you wake up tomorrow, you will still be greeted by a clean, translucent vessel. [Pricing & Developer Program] We believe in extreme transparency and sincerity. Time management is a long-term habit. To let you fully and completely experience the physical resistance and settling sound of Time Vessel before deciding to pay, we offer a 7-day free trial. After the trial ends, you can flexibly choose a short-term subscription plan based on your needs; to maintain the purity of the product and indie development, we also retain the most traditional and simple one-time purchase "Lifetime" option. We absolutely do not set sneaky hidden charges, giving the choice entirely back to you.

Verdict
Face Diary and Time Vessel are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
