The next thing is already decided. Rundle runs your routine one step at a time, so you are not standing in the kitchen at 7am deciding what happens next. A calm ring counts down. When it ends, the next step is already on screen. Built for how ADHD actually works: • One step at a time. Not the whole list. • A visual countdown you can read from across the room, and on your lock screen. • Park a thought the moment it interrupts you, and come back to it when you are done. • See the week you actually had. No streaks to protect, no guilt for the days you missed. Every routine is free. All of them. There is no cap and no upsell in the middle of your morning. The one time upgrade adds routine reminders and every theme. No subscription. No account. No ads. No AI. Your data stays on your device and syncs privately through your own iCloud. There is no server, so there is nothing for us to see. Accessibility is not an afterthought: • Full VoiceOver in the routine runner • Dynamic Type up to the largest accessibility sizes • Reduce Motion honored • Haptics can be switched off
