About

Scalyx

Read full description

Scalyx is a safe space, not just a planner. Breathe here, log how you feel. And when you want to, lay out your day. Scalyx is made for ADHD brains and for anyone who gets overwhelmed easily. THE SAFE SPACE Guided breathing you follow with your eyes, long enough to come back down when everything is moving too fast. One affirmation a day: 365 of them, written one at a time, each with a short version for the days you’re only passing through and a longer one for the days you want to sit with it. A mood journal: note how you’re doing, without owing anyone an explanation. YOUR DAY, GENTLY Cards instead of a list: a colored icon, a time, sub-steps, a reminder. You tick it off and the title quietly gets crossed out. That’s it. A quick capture inbox: write it down now, plan it later. The idea is safe, and your head is clear. AN ASSISTANT THAT BREAKS THINGS DOWN Talk to it in English or French, by voice or by typing. Hand it the big task you can’t find a way into: it splits it into small steps and offers a schedule you accept with one tap. It can reschedule and edit too, when the day changes its mind. Your conversations are saved, and you can reopen them any time. STAYING WITH IT A focus timer that keeps running on the Lock Screen and in the Dynamic Island. Put the phone down and it keeps counting for you. EVERYTHING IN ONE PLACE Import your iPhone calendar and reminders, so there is nothing to copy over. YOUR DATA Private iCloud backup: switch phones, reinstall, and it’s all still there. When you write to the assistant, your message and the titles in your day are sent to an AI service to build the reply. Nothing else leaves your iPhone and your iCloud. MAKE IT YOURS 7 accent colors plus one of your own, 9 app icons, 2 typefaces (New York and Charter), light and dark mode. The app is in English and French, affirmations included. WHAT THE SUBSCRIPTION COVERS The assistant, sub-steps, rescheduling, early reminders, calendar and reminders import, colors and icons are part of the Scalyx subscription, which renews automatically. The rest works without it. Terms of Use: https://scalyx.app/conditions Privacy Policy: https://scalyx.app/confidentialite Scalyx is not a medical tool. It doesn’t diagnose anything, it doesn’t treat anything, and it doesn’t replace professional support. It’s a calm place to organize your day, at your own pace.
