SmallStepper – A Simple Task Manager, Habit Tracker, and ADHD-Friendly Planner Too many things to do? Not sure where to start, even after making a to-do list? SmallStepper helps you focus by showing you just one small step at a time. Break down goals, routines, and everyday tasks into manageable steps. Instead of seeing an overwhelming list, the home screen displays only the one thing to do right now. No complicated dashboard. No information overload. Just one clear next step. SmallStepper can be used as a simple task manager, daily planner, habit tracker, routine planner, and productivity tool for anyone who finds traditional to-do lists overwhelming. 【How It Works】 1. Create a goal. 2. Break it down into small, achievable steps. 3. Focus on the single step shown on the home screen. 4. Complete it and move on to the next step. For example, when the developer finds it difficult to get out of bed in the morning, they use small steps such as: “Move my hands and feet” “Roll out of bed” “Drink some water” Even a difficult task can feel more manageable when it is broken down into tiny steps. 【Features】 ・Focus on one task at a time ・Break large goals into small, manageable steps ・Create morning routines, evening routines, and daily habits ・Use repeating goals to build consistent habits ・Work toward shared goals together with others ・Sync your data across multiple devices, including iPhone, iPad, and Mac (Supporters only) ・Schedule reminders and task notifications ・Review completed tasks in your history ・Level up and unlock titles as you make progress ・Receive encouraging messages after completing a step ・Turn encouragement messages off in Settings ・Check your current step from an Apple Watch ・View your current task with a home screen widget ・Use Easy Japanese and multiple language options ・Simple and distraction-free interface 【Useful For】 ・ADHD-friendly planning ・Managing attention and distractibility ・Starting tasks when you feel overwhelmed ・Daily task management ・Habit tracking ・Morning and bedtime routines ・Studying and school assignments ・Work and productivity ・Tidying and household chores ・Remembering what to bring ・Breaking down large or stressful tasks SmallStepper was designed by a clinical psychologist with the aim of making task management easier for people who experience inattention, distractibility, executive function difficulties, or information overload. You do not have to complete everything at once. Focus on what you can do right now, take one small step, and create more moments of “I did it!” Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
