■ Beyond "I messed up yesterday, forget it" Piano practice, drills, memorization… "Only 5 minutes yesterday." "Not feeling it today." If that counts as zero, nothing sticks. TodoFarm plants each task as a seed and lets kids water it by the amount they did. 5 min = 5 min's growth. 20 min = 20 min's growth. Every bit of effort grows the plant. Hit 100% and harvest the reward. ■ Easy to use (3 steps) ① Parents plant seeds like "10 hours of piano" or "30 pages of drills" ② Kids log each day's amount (time / count / pages) = watering ③ Reach 100% and harvest the registered reward! Units: hours, count, or pages. Against a 10-hour goal, today's 30 minutes = 5% banked. Yesterday's effort doesn't disappear tomorrow. ■ What's different — 0/1 becomes 0-100 If tracking is just "done or not done," a 5-minute day counts as failure. Perfectionist kids give up on the whole thing. TodoFarm accumulates whatever they put in. "5 min today, 20 min tomorrow, 0 the next day." With waves, total progress still moves forward. ■ Wither feature — slip up, then come back You can also wither plants manually. On days when you can't keep going, wither it from the parent panel. When you decide to try again, you can pick up where you left off. "It's about to wither — let's go!" ■ Choose the daily watering limit "Water once per day" / "Unlimited" — both work. Lessons: once a day. Exercise: many times. Flexible. [Tips for setting up tasks] · Start with small seeds that can ripen in 3-7 days. Let them feel the joy of harvest early. · Pick the unit that fits the goal: Piano → time (minutes) Drills → pages Recitation → count ■ Great for kids and families who… · Have big motivation swings · Give up after one missed day · Are perfectionist about 100% or nothing · Work on long cumulative goals (lessons, drills) · Want to move forward even a little · Need to see "I did try today" visualized TodoFarm measures total effort, not 0/1 completion. Keep going on the wavy days. ■ Safe and private · Ads appear only on the parent management screen. The farm screen kids use is completely ad-free. We don't track users. · All your child's data stays on your device. Nothing is sent externally. May your days feel a little lighter. ■ Sister apps "TodoBank" — bank promises in a passbook — "how many to go" shows as a balance. "TodoGatya" — for slow mornings — kids draw the next task from a gacha and start with a surprise.

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
The clearest difference is in-app purchases: TodoFarm at none against Time Vessel's 3. TodoFarm also leads on iOS requirement (15.1 vs 17.6). Time Vessel's advantage is update cadence (fortnightly vs every 6 weeks). On price, ads and device support there is nothing between them.
