Build consistent habits with Sequential, an animated checklist that walks you through your own routines, workouts, musical practices, study sessions, meetings, or anything you can dream of. Designed to help you stick with it! Allow for the variables in life: It’s difficult to stick to routines in the midst of our chaotic lives. So when you run a sequence, you chose between three levels: the essential, moderate, and ambitious versions of your routine to account for the time or energy you have. Repeating the essential steps of a sequence builds the muscles to keep you on track, and makes sure you’re achieving the necessities. Structure without stress: Each step in a sequence only completes when you say it’s done, with customizable nudges to keep you on track without feeling like you need to beat the clock. No streaks: Focus on the day ahead without being shamed for missed days. No unnecessary data or bells and whistles to distract you while you’re trying to build a habit. Built for everyone: Designed by and for people with ADHD, but flexibile enough to help anyone who wants to do more with less time. And it fully supports VoiceOver and other accessibility features, so nobody is left out. I’m an independent developer and I’ve created Sequential to fill a real need in my own life. My priority is providing a useful and easy to use product, rather than price gouging and upselling. That means no tracking, no ads, and no AI. I don’t want your data, so Sequence doesn’t collect it. Features: - No ads, even in the free version - Optional voice notifications to speak each step of your routine out loud - Assign each step a level to allow your routine to fit into the time you actually have - Freely customziable push notifications to keep you on track - Assign an emoji to each step to quickly identify it at a glance - Simple and calm design that feels at home on iOS - 7 different timer styles, from whimiscal to minimal - Schedule your sequences to start at or end by a certain time, and get reminded when it’s time to start - Import and export your sequences to a plaintext format at any time - Full support for VoiceOver and other accessibilty features - Create unlimited sequences* - Choose from 16 themes and 37 different app icons* *Requires Sequential Unlimited purchase Terms of service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy policy: https://sequentialapp.net/privacy
