RollGuard
Read full descriptionHide full description
Find the sensitive photos hiding in your camera roll before someone else does. RollGuard scans your photos for passports, driver's licenses, national ID cards, payment cards โ including card backs โ screenshots of passwords and credentials, photographed WiFi and router labels, and other private images โ entirely on your iPhone. It even scans in Airplane Mode โ proof that nothing is uploaded, nothing is analyzed in the cloud. There's no account to create. Review what's flagged, then keep, hide, or delete โ you're always the one who decides. RollGuard finds identity documents wherever they're hiding in your camera roll โ passports, national ID cards, driving licenses, health and tax documents, residence permits โ built and tested against real specimen documents from 180 countries and territories, in more than 30 languages. It doesn't just spot things that look like documents: passports and modern ID cards from any country are read and checked against their own machine-readable rules, and anything it can't verify is still flagged for you to decide. Passports from 100 MRZ-verified states have checked out against their own check digits in testing. Deep coverage for Australia, New Zealand, the UK, Ireland, Canada and the US, broad coverage across Europe โ and growing. Before you hand over your work phone. IT prepping a device for return, or handing one back yourself โ a fast scan flags anything private that shouldn't travel with the hardware. Before you sell or trade it in. Old passwords, screenshotted 2FA codes, a photo of your license from years ago โ RollGuard finds what a factory reset alone won't help you notice before it's gone for good. Before you hand your phone to family. Kids playing games, family scrolling through photos โ a quick pass first means nothing private turns up by accident. Before you travel. A lighter camera roll for border crossings and unfamiliar hands. Or just a spring clean. "What's actually in my thousands of photos?" โ most people genuinely don't know. Find out what's hidden in there. RollGuard's free tier does more than a typical free trial: it runs a genuinely complete scan of your last 30 days โ every category, every action, no artificial limits inside that window, re-scannable anytime โ with the full review queue included: real thumbnails, tap to zoom, and keep, hide, or delete, all free. It also keeps going: working through the rest of your library on its own, showing you a real running count of what's flagged out there. Pro unlocks the review queue for everything beyond your last 30 days โ without it, finding a specific older flagged photo yourself would mean scrolling through thousands of images by hand; Pro does that for you. One-time purchase, forever: no subscription, no recurring charges, ever. RollGuard also flags possibly sensitive images using Apple's own on-device detection, following your iPhone's Sensitive Content Warning setting โ nothing about those images ever leaves your phone either. RollGuard never tells you your library is "safe." It flags what it finds for your review โ you make every call.

Your calendar manages your schedule. Annidiem remembers the days for you. If you think you're a bit ahead of the curve, this one's for you. Birthdays, weddings, exams, trips, the day your baby arrived, the day you moved in โ the days that matter deserve better than a crowded calendar. Some are still ahead of you. Some already happened. Either way, they deserve somewhere to stay. Flip the bottom-right corner of a card and it turns over into that day's own record. You don't have to wait for the day itself โ write while you're looking forward to it, while you miss it, or the moment it crosses your mind: photos, thoughts, voice memos, short videos, each one stamped with the place and weather of that moment. No folders to create, no "where should this photo go" โ it belongs to a day, so it stays with that day. If you remember which day it was, you'll find it again. And when the same day comes round again, every year keeps its own: this year never mixes with last. When a day is no longer in focus, put it away โ not throw it out. It leaves your home screen and stops reminding you, while the diary and photos stay, ready to bring back. Life gets simpler. The memories don't have to. - TALK TO THIS DAY โ flip a card over for that day's own record; write whenever it comes to you - ARCHIVE โ put days that no longer need your attention away, without deleting anything - CARD WALL โ big countdown numbers for every day that matters - TICKING MOMENTS โ live days/hours/minutes/seconds; past days keep counting up: 1000 days together, 90 days smoke-free, day 300 of the project - WEEK & DAY OF YEAR โ which week and day of the year today is, at a glance - PHOTO COVERS โ pick a photo for a date and the card becomes its face - ON THIS DAY โ the days that happened on today's date in past years surface on their own - DYNAMIC ISLAND โ pin any day to your Dynamic Island - WIDGETS โ gradient cards, Lock Screen widgets, and a large widget that shows your next five days - ERA OF DAYS โ one 3D timeline for all your days: days with photos stand along the road, tap one to fly in - APPLE WATCH SYNC โ a glance at your wrist: watch app and watch face complications, updated from your iPhone - TAKE A BREATHER โ the screen dims, and the fireworks begin - WORTH SHARING โ five share card styles: gradient, minimal, poster, midnight, photo - ANY RHYTHM โ daily, weekly, monthly, or an interval you set yourself; paydays and bill days stay in step - FIND ANY DAY โ search titles, notes, even "August"; filter to this month, the next 30 days, or what's already past - ASK SIRI โ "how many days until New Year?" works, and so do Shortcuts and system search - REMINDERS YOUR WAY โ the day itself, or 1/3/7/14/30 days ahead, at a time you choose - TYPE DAYS, GET DATES โ enter "100 days" and the date computes itself - FACE ID LOCK โ auto-lock in background; some days are yours alone - CALENDAR BRIDGE โ import from system Calendar; export .ics/JSON to iCloud Drive - ICLOUD SYNC โ sign in to iCloud and every device stays in sync - DATE CALCULATOR โ days from birth to today, or today to payday; days between dates, business days, and more - ON-DEVICE AI BLESSINGS โ Apple Intelligence writes personalized blessings, fully offline (iPhone 15 Pro or later) One-time purchase ยท No subscription ยท No ads ยท Collects no data โ your data stays on your device and in your own private iCloud database, and everything works offline.

Verdict
The clearest difference is in-app purchases: Annidiem at none against RollGuard's 1. Annidiem also leads on device support (3 vs 1) and iOS requirement (18.0 vs 26.0). On price, update cadence and ads there is nothing between them.
