FAQ
- Does the widget update by itself?
- Yes. The Duodays widget updates at midnight on its own, so the day count changes without opening the app.
- Do I need to sign up to set a D-day?
- No. There is no account or sign-up. Pick the day you got together and you are done.
- How is Day 100 calculated?
- By default the day you got together is Day 1, so Day 100 falls 99 days after your start date. If you prefer, switch the counter to count the first day as Day 0.
- Does it remind me of monthly anniversaries, not just the yearly one?
- Yes. Duodays counts 1 to 11 months, every yearly anniversary and every 100 days, and reminds you a week before, the day before and on the day.
- Can I track more than one relationship, like my pet?
- Yes. Add extra counters for friends or a pet next to your couple counter.
- Can I add our photos?
- Yes. Add a photo for each of you on the couple card, and attach a photo to each memory.
- What happens to my data if I change phones?
- Everything stays on your phone. Export a backup file, photos included, and restore it on your new phone.
- Does Duodays have ads?
- Yes. Duodays shows ads to keep the app running.
