You're not lazy. You're not broken. You just have a task app that doesn't get it. It shows you everything at once. All 47 items. And somehow expects you to "just prioritize" when you're already running on empty. So you stare at the list. Feel overwhelmed. Close the app. Feel guilty. Repeat tomorrow. We built something different. WHAT IF YOUR LIST GOT SHORTER ON HARD DAYS? Not because you deleted things. Not because you gave up. But because the app understood that today isn't yesterday. Open KammyTask. Tell it how you're feeling—like checking a battery. On rough days, you only see what you can actually handle. The overwhelming stuff? Hidden until you're ready. No guilt. No "you're falling behind." Just a shorter list that matches your reality. "BUT I'VE TRIED SO MANY APPS" We know. We've tried them too. Apps that punish you for missing a day. Apps with 47 features you'll never set up. Apps designed for people who wake up energized and stay that way. That's not us. That's probably not you either. If your energy is unpredictable—whether that's ADHD, chronic fatigue, long COVID, fibromyalgia, autoimmune stuff, burnout, or just life—you need a list that flexes with you. If you've ever said "I just need a low-key day" and wished your task list would listen, this is that. IF SPOON THEORY MAKES SENSE TO YOU This app will too. Some days you have twelve spoons. Some days you have two. Most apps don't care—they show you a twelve-spoon list regardless. KammyTask asks how many spoons you've got, then shows you a list that fits. THOUGHTS RACING? JUST TALK. You don't have to type when your brain is spinning. Open the app, hit record, say everything that's bouncing around in your head. AI turns the chaos into a list. You didn't have to organize anything. BIG TASKS FEEL IMPOSSIBLE? "Clean the house" isn't a task. It's a mountain. Tell us the mountain. We'll break it into steps small enough to actually start. REST COUNTS HERE Took a break? Log it. Went for a walk? Log it. Sat outside for five minutes? That counts. Self-care isn't cheating. It's part of your progress. WE WON'T MAKE YOU FEEL BAD No "Don't forget!" notifications. No "You're falling behind!" warnings. No streaks that break and make you feel like a failure. Come back after a week away? We just say welcome back. That's it. Your progress is a number that only goes up. Tasks, rest, small wins—they all count. Nothing gets taken away. BUILT BY SOMEONE WHO GETS IT We made this for family members who needed a different approach. Watching them struggle with apps that made hard days harder—that's why this exists. We're not here to fix you. We're here to work with how you actually are. This is a task app, not a medical tool. But it's a task app that finally makes sense. TRY IT BEFORE YOU DECIDE No signup required. No credit card. No "enter your email to continue." Just open the app and start. See if it clicks. If it helps, stick around. $3.99/month with a free trial—we kept it accessible on purpose. If it's not for you, no hard feelings. We hope you find what works. YOUR ENERGY CHANGES. YOUR LIST SHOULD TOO. Download KammyTask.
