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 — including card backs — screenshots of passwords and credentials, photographed WiFi and router labels, and other private images — entirely on your iPhone. It even scans in Airplane Mode — 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 — you're always the one who decides. RollGuard finds identity documents wherever they're hiding in your camera roll — passports, national ID cards, driving licenses, health and tax documents, residence permits — 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 — and growing. Before you hand over your work phone. IT prepping a device for return, or handing one back yourself — 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 — 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 — 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?" — 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 — every category, every action, no artificial limits inside that window, re-scannable anytime — 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 — 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 — 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 — you make every call.

About

Voice Note to Text

Features
Read full description

Read your voice messages instead of listening to them. Share a voice note to the app, and a few seconds later the text is on screen, ready to copy into a reply or share as a .txt file. HOW IT WORKS 1. Long-press a voice note in your chat app, tap Share, then "Copy to Voice to Text". Or pick any .opus, .m4a, .mp3 or .wav file from Files 2. The language is detected automatically; around 100 languages are supported 3. Read the transcript, tap Copy, or Share .txt Transcription runs entirely on your iPhone using a speech-recognition model that ships inside the app. Nothing is uploaded, no account is needed, and it works with no internet connection at all. WHY IT IS DIFFERENT Most transcription apps send your audio to a server and charge a monthly subscription. This one does neither: your first 3 transcriptions are free, then a single one-time purchase unlocks unlimited use, and your recordings stay on your phone. It is built for voice notes you already have, from any chat app, in any language, on any iPhone, with no regional restrictions. BUILT FOR • Reading voice notes in meetings, on the train, in a library • Voice messages in a language the built-in transcript does not cover • Keeping a searchable text copy of important messages • Voice memos, voicemail and interview recordings PRIVATE BY DESIGN • 100% on-device speech recognition • Works in airplane mode • No account, no sign-up, no analytics • Your audio and your transcripts never leave your phone Free to download, with 3 transcriptions included. After that, one one-time purchase unlocks unlimited transcriptions. No subscription, ever. Voice Note to Text: Offline is an independent utility. It is not affiliated with, endorsed by, sponsored by, or in any way officially connected with WhatsApp LLC or Meta Platforms, Inc. WhatsApp is a registered trademark of Meta Platforms, Inc.
