DOTS CALENDAR — Countdown Widget Dots Calendar puts a beautiful, minimal calendar right on your home screen. Every day of the month is rendered as a filled circle, giving you an instant visual sense of where you are in the month — and how much time you have left until the next big day! SET A DEADLINE. Watch the days count down. Add a target date and Dots Calendar shows you exactly how many days remain. Whether you're counting down to a trip, a deadline, an event, or anything else that matters to you, the countdown is always a glance away. PROGRESS AT A GLANCE. Enable the progress bar to see a visual timeline stretching from your chosen start date to your deadline. No numbers to crunch — just a clean, satisfying bar that moves a little each day. MAKE IT YOURS. Customise the colour of today's marker, your deadline day, and the widget background. Prefer a fixed look regardless of your system appearance? Switch between Dynamic, Light, and Dark background modes with a single tap. SIMPLE. PRIVATE. NO NONSENSE. Dots Calendar collects no data, requires no account, and has no subscription. A one-time Lifetime license unlocks full colour customisation.

Verdict
The clearest difference is in-app purchases: NFC Toolkit at none against Dots Calendar's 1. NFC Toolkit also leads on update cadence (every 5 days vs every 5 weeks) and iOS requirement (15.0 vs 18.2). On price, ads and device support there is nothing between them.
