PicDiary alternative for choosing, not collecting
PicDiary is the better pick if you want a calendar of daily photo highlights with voice notes and monthly stories. Signet is the better pick if you want to keep only the few moments that matter, with a sentence and a seal, no daily reminders and no purchases. Neither promises cloud backup, so keep your photos in your own library too.
Both apps treat photos as the center of a journal. PicDiary invites you to fill the days of the month; Signet invites you to keep only a few.

What PicDiary is
PicDiary, by Benedikt Kehl-Waas, is described in its listing as a photo journal that combines a diary with a photo album. It lists a calendar view, up to five photos and notes per day, voice notes with a transcript that can be polished by AI, random daily memories, monthly stories, favorite days, daily reminders and widgets. It supports eleven languages, requires iOS 13.0 and is free to use with optional Pro features. The US store shows about ninety ratings averaging near 4.9.

Where PicDiary is stronger
- A friendly daily habit. The calendar view and gentle reminders suit people who do want a routine of one highlight a day.
- Voice notes. Speaking a moment and getting a transcript is something Signet does not offer.
- Wide system support. It requires only iOS 13, so older phones can run it.
When to choose PicDiary
- You enjoy the ritual of a daily highlight and want reminders to keep it going.
- You want to capture the day by talking.
- You have an older iPhone that cannot run iOS 17.
When to choose Signet
- A calendar full of empty days makes you feel behind. Signet has no calendar to fill.
- You want each kept moment to feel chosen, with a seal and a date.
- You want a year-end scroll of what mattered, not every day.
- You want no purchases at all.
Moving from PicDiary to Signet
There is no import between the two. Choose the best moments from your PicDiary calendar and add them to Signet one at a time with a line and a seal.
Keep PicDiary for the daily habit if you enjoy it, and use Signet for the few moments you want to keep as objects.
A practical test is to use PicDiary through one month and then count the days you filled out of obligation rather than interest. If that number is high, Signet's one-moment-at-a-time approach, with nothing to fill and no reminder to answer, may be the gentler fit.

Frequently asked questions
Is Signet like PicDiary?
Both are photo-centered and private, but PicDiary is built around a daily calendar and Signet around a few chosen moments with a seal.
Do they back up my photos?
Neither promises cloud backup in its listing as we read it. Signet says plainly it does not provide backup, so keep your photos in your own library.
Which is free?
Both are free to download. PicDiary has optional Pro features, and Signet has no purchases.
Can Signet record voice notes like PicDiary?
No. Signet takes a photo or a sentence and a seal, without audio.
Does Signet show a calendar of my days?
No. It shows a collection of the moments you kept and a year scroll, not a calendar that marks empty days.
Signet is for the moments worth keeping: a photo, a sentence, and a seal.
