App that turns photos into postage stamps on iPhone
Stamp Diary's capture flow is built around the stamp itself. Open the in-app camera and a perforated, stamp-shaped frame sits over the viewfinder, so you compose inside the final shape instead of cropping afterward. A Square option sits next to the shutter, a flip button switches between the front and back cameras, and a library button lets you pick an existing photo from your camera roll instead of shooting a new one.
After the shutter, you name the stamp and save it straight to your diary. Every stamp is marked with its capture date and time (for example '08 Jul 2026, 12:04') and placed on that day's page, so the timeline builds itself. Open any stamp later to view it full size, attach an emoji, edit its name or details, or share it on its own. This is what makes it a photo stamp journal app rather than only a stamp camera app with stamp-shaped viewfinder: the stamp is the entry, not just an export.
How to organize photo stamps into custom collections
The Collections screen starts with two built-in sets: All Collection, which holds every stamp, and Favorites, which fills up as you mark stamps for quick access. Below them sit your Custom Collections. Tap the plus button, give the collection a name such as 'Travel', 'Rare Finds' or 'Flowers', and add stamps to it; the Flowers card in the screenshots shows a preview row of its stamps, a count of 3 and the date 8 Jul 2026.
You can rename or update a collection anytime and add or remove stamps. The same stamp can appear in more than one set: in the screenshots the bouquet stamp sits in both All Collection and the custom Flowers collection. The description says the collection stays tidy and searchable, so this digital stamp album app stays easy to browse.

Notebook-style diary app with a new page for every day
Most photo journals show an endless scroll. Stamp Diary is instead a daily photo diary app, closer to a one-photo-a-day journal: one page per day, in a page-based layout that behaves like a paper notebook. Each date gets its own page, the page shows that day's stamps in a grid with their times, and moving between days is a page flip. A Today button jumps back to the current date, and the description says you can flip through dates to revisit earlier entries.
An empty day is not hidden; it appears as a blank page with a note that there are no stamps yet, which is a small nudge to capture something. The point of the design is focus: you see one day at a time without clutter. The same page layout is what gets exported when you share, so this aesthetic visual diary app for iPhone looks the same on screen and in a post.
Stamp diary app with iPhone Home Screen widgets
Stamp Diary ships with Home Screen widgets, shown in its App Store screenshots. The medium widget is labelled 'Latest Stamp' and displays the most recent stamp beside its date and weekday; the small widget shows a single stamp with its date. Placing one on the Home Screen means the last moment you captured is visible without opening the app, which works as a gentle reminder to add today's page.
Widgets are not mentioned in the App Store description; the screenshots are the source, and they show one medium and two small widgets on an iPhone Home Screen. The two small widgets in that screenshot show different stamps from the medium one, so the small widget is not limited to the latest stamp; the listing does not document how each widget picks its stamp.
How to share a diary page as an image on social media
Sharing in Stamp Diary is one tap from the share icon at the top right of a page. The app renders the whole day (header, date, weekday and stamp grid) as a single clean image so you can send it to any app. In the screenshots the exported page is opened in a social story editor, which is the intended use: the layout is built to look right in a post or story without extra cropping.
The same works for collections: you can share a collection snapshot instantly, and single stamps have their own share button on the detail view. The description frames this as celebrating milestones in your stamp journey, but a plainer use is sending a day's page to family in a group chat instead of nine separate photos.
