Duet is a shared calendar for couples. Your anniversaries come with reminders, and the things you want to do together can go on the calendar and into to-do lists you can both see. See when your partner is free, never forget your relationship anniversary again, and actually take the trip you keep talking about. Keep everything the two of you share in Duet. SHARED CALENDAR You both see each other's plans, even when you're long-distance. Who's busy this weekend? When do you see each other next? Open the app and you'll know, no more asking "wait, what time was that?" Set weekly or monthly events to repeat, and add a reminder before they start. CALENDAR IMPORT Connect Apple Calendar or Google Calendar, pick one of your calendars, and its events show up next to your shared plans. You decide whether your partner sees them. ANNIVERSARY REMINDERS Birthdays, the day you met, the day you got together. Duet counts the days for you. Set a reminder and you'll hear about each birthday and anniversary ahead of time, plus milestones like 100 days, 200 days, and every year together. HOME SCREEN WIDGET Put the anniversary that matters most on your home screen and see how many days you've been together without opening the app. SHARED WISH LIST The cities you want to visit, the exhibitions you want to see together, the things you'd like for your birthday. Either of you can add to the list anytime. FROM WISH TO PLAN Write notes on a wish. That trip you want to take together? When you're ready, put it straight on the calendar and add to-do lists for it too. SHARED TO-DO LISTS Give each to-do an owner and a due date. To-do lists you add from a wish stay linked to it, so you both know what they're for. Download Duet and keep your plans, your important dates, and what you're getting ready for next in one place.

PinyPiny Life isn't something you only write down. It's something you piece together. Some days need only a sentence. Some memories deserve a photo. Some passing ideas feel right in a different font, a little color, or a sticker made from something you just photographed. PinyPiny is a visual journal where notes do not have to stay inside the lines. Words, photos, papers, fonts, colors, stickers, and animation can all become part of the way you remember. Write a simple diary entry, build a scrapbook-like collage, or shape each page like a tiny magazine made just for you. A different way to revisit your notes Open PinyPiny and your past entries become a stack of cards floating in a quiet, deep space. Swipe through them one by one and make finding an old note feel like part of the experience. Make every page your own • Choose from different papers and fonts, then pair them with the colors you like. • Move, rotate, and arrange content instead of keeping every line in a fixed column. • Place photos on the page or embed them directly between words. • Photograph something you love and turn it into your own sticker. • Add a touch of animation when a still page is not quite enough. A trip can hold photos, colors, and words from another language. Dinner can become the collage of the day. A sentence can sit proudly in the center of the page. A cat, a ticket stub, or a rainy afternoon can each have a place of its own. No design experience required There is no single right way to make a note here. Keep it neat or let it wander. Make it minimal or fill the page. Write three words today or spend half an hour arranging every detail. It is still your note. When a page feels complete, export it as an image and save it to Photos. The small pieces of an ordinary day can slowly grow into a visual journal that belongs only to you. PinyPiny is more than a place to keep information. It is a sheet of paper that can keep changing—a home for ideas, photos, and fragments of life. Piece together what happened today, the people you love, the places you visited, and the thoughts that appeared without warning. Years from now, may you find more than a paragraph. May you find the day as it really felt. Privacy Policy: https://pinypiny.lraitech.com/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is ads: PinyPiny at none against Duet's shown. PinyPiny also leads on update cadence (every 2 days vs weekly). Duet's advantage is iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.
