Ruby Roll [Photo Diary]

This month, gone before you know it. Can you remember what you were doing last month? Ruby Roll is an app where you pick just one photo a day, and it fills in your calendar. By the end of the month, you can see your whole month at a glance. It's all there in your camera roll, but the month itself is gone. The photos remain — the memory doesn't. What you need isn't more photos saved. It's one decision, made every day. -- You choose, so you remember -- Photos are never picked for you. You decide which one represents today. Research backs this up: things you choose yourself are remembered better than things chosen for you. A photo an algorithm picked just drifts by. A photo you picked becomes a cue you can return to. Still, all you have to do is choose. Photos from that day are right there — just tap one. It takes seconds. No writing required. -- Made for you if -- ・You've tried journaling before, but it never stuck — though you always have your phone out ・Your camera roll is too full to ever look back at ・Someone asks "how's it going?" and you go blank ・You want to remember your kid's or pet's everyday moments, not just the big ones ・You want to see a hobby or workout routine laid out, month by month -- What you can do -- ・Pick one photo from that day's shots, and it joins your calendar ・Go back and fill in past dates too ・Videos count as "today's pick" too ・Add a widget to your Home Screen, and see this month at a glance ・Turn a full month into one shareable image ・Get a gentle nightly reminder to pick (time and on/off, your call) -- Before you start -- ・Your photos stay on this device. They're never sent to the developer or anyone else ・The only time a photo leaves your device is when you choose to share it ・Photo access is used only to show your photos in the calendar ・No account, no email required ・Miss a day? Nothing resets. You can always go back and fill it in ・Empty squares don't ruin the month -- Ruby Roll Royal (optional) -- The core app stays free, always. ・Add notes to your photos ・Pick more than one photo per day One photo a day. That's all it takes to keep the month. Ruby Roll — make the everyday a little more worth holding onto.
