Full functionality with a small one-time unlock fee, no subscriptions! Your task list should match how your brain actually works — one thing at a time. SingleThread turns your Apple Reminders into a single, calm, focused list. Instead of an intimidating wall of everything you "should" do, you see one clear reminder at a time, in order, and you process it — complete, skip, or delete — before moving to the next. It's built for people who feel overwhelmed, who are neurodivergent, or who simply want their to-dos to stop feeling like noise. Why it helps • One at a time. Your human brain does one thing at a time — your task list should reflect that. Just one reminder fills the screen, so every task gets your full attention. • Order that makes sense. Sort by priority, by due date (soonest first), or alphabetically. Pick whichever removes the most thinking. • No decision paralysis. See the reminder, act, move on. Fast. Smooth. Calm. Everything you need, nothing you don't SingleThread stays out of your way, but it's as full-featured — or as bare — as you want. Every capability can be turned on or off in one simple Settings screen: • Complete, Skip, or Delete each reminder with a tap, a swipe, or the action buttons. • Hide reminders from projects you don't want to see (with "Excluded Projects"). • Hide undated (someday) reminders, or show them when you're ready. • Show or hide reminder dates — keep the screen as minimal as you like. • Fast add by voice: dictate a reminder, complete with due date and recurrence, right from the microphone button (or hide it with one switch). • Change how it looks: System, Light, or Dark appearance, plus larger text sizes across the whole interface. Thoughtful by design • Works with your existing Apple Reminders — everything you've already captured stays right where it is. Two-way, in place. • Calm visual design that gets out of the way. Big, legible text. Nothing flashing at you. • Accessible — designed with clear hit targets, complete descriptions and labels, and full support for Apple's rendering commands. Built for quiet productivity Whether your to-do list is a source of anxiety or just a source of clutter, SingleThread gives you a smaller, softer way through it. One item at a time, in an order you choose, at the pace that feels right. Enable the features that help, hide the ones that don't. Your reminders. One at a time. In order. At your pace. SingleThread works with your existing Apple Reminders and syncs across your devices. Available on iPhone, and iPad, with a matching Apple Watch app and widgets; install on any one to get going. No account to create — your reminders stay in place.

Verdict
The clearest difference is ads: SingleThread at none against When's shown. When's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.
