Keepy hides your private photos, videos and documents behind a PIN. A second PIN opens a decoy vault that looks exactly the same, so you can show it instead of the real one. START WITH YOUR FIRST FILE Create your PIN and open your vault. Add photos, videos or documents, organize them into albums and return to your saved collection whenever you need it. Viewing saved files works offline. CAREFUL IMPORTS Keepy checks that a copy was written and its record saved before offering to remove the original from Photos. Import results show what succeeded and what needs another attempt. Removing originals is your choice. BACK UP AND RESTORE Create a ZIP backup of your photos, videos, documents and albums. Password protection is enabled by default, and Keepy verifies the archive before sharing. Restore a Keepy backup into a vault while keeping existing files. Store the archive outside Keepy and keep its password somewhere safe. PINs, browser sessions and settings are not included. SEPARATE VAULTS Use different PINs for separate collections. Add as many optional decoy vaults as you like, and let any vault ask for its PIN more than once. Every vault has the same screens and settings. Choose another app icon for your Home Screen. These features offer discretion, but they cannot guarantee protection against inspection or coercion. MORE WAYS TO USE YOUR VAULT Browse with a separate web session for each vault, open Telegram or WhatsApp web sessions, and use on-device photo enhancement. Online services require an internet connection and follow their own privacy policies. FREE AND PAID OPTIONS Start with a free vault with import limits and advertising. Paid plans offer larger or unlimited allowances and remove ads. Unlimited storage is limited by your iPhone's free space. Everything you added before version 1.11 always stays accessible. Without an active plan, your newest items within the free limits stay open. Other items are locked but kept, can be deleted at any time, and are always included in Keepy backups. PRIVACY AND RECOVERY Vault files stay in Keepy's storage unless you choose to share, export or upload them. iOS Data Protection protects files on the device. The vault PIN is an app lock, not a file-encryption key. Keepy uses analytics and ads, with controls in Vault settings. There is no automatic cloud recovery and no forgotten-PIN reset. Back up before deleting the app or replacing your phone. SUBSCRIPTIONS Available plans, localized prices and any eligible free trial are shown before purchase. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account subscription settings. Free trials are available only to eligible accounts for the selected plan.

The translation, right where the original text was. Play a Japanese game, read a Chinese comic or browse an overseas shop, and OS Translator reads the text on your screen and translates it on the spot. While you use any other app, OS Translator reads your screen and shows the translation in a Picture in Picture window. When the screen changes, the translation follows within about a second. No screenshots, no copy and paste. TWO WAYS TO READ • Mirror mode — Place the PiP window at the top or bottom of the screen, and it mirrors the other half with the translation laid over the original text. Speech bubbles and product pages read just as they look. • Subtitles mode — Game dialogue, menus, chat and captions burned into videos appear as a list in the PiP window, starting with the paragraphs closest to what you're reading. • On iPad, put another app next to OS Translator in Split View or Stage Manager. The app mirrors it and lays the translation right over the original text. HOW IT WORKS • Pick the language to read and tap Start Translating. • Share your entire screen when iOS asks, then go to your game, comic or app. • Move and resize the translation window as you like. Stop anytime from the app or the screen recording indicator. GREAT FOR • Dialogue and quests in Japanese games • Manga, webtoons and web novels that haven't been translated yet • Product names, options and details in overseas shops • Social media and forums in other languages • Captions burned into videos ALSO • Reading direction for vertical manga • Choose whether to show the original text • Recent Translations keeps what you read so you can view and copy it again EVERY FEATURE FREE No limits on time or number of translations, and every feature is free. A short ad may play before you start translating. The only purchase is Remove Ads — buy once and it's yours for good. TRANSLATED ON YOUR DEVICE Reading the screen and translating both happen on your device with Apple's built-in text recognition and translation. What's on your screen is never sent anywhere or saved. Once a language is downloaded, translation works even in Airplane Mode. LANGUAGES Translate between 20 languages, including English, Japanese, Korean, Chinese (Simplified and Traditional), Spanish, French, German, Portuguese, Russian, Arabic, Hindi, Thai, Vietnamese and more.

Verdict
The clearest difference is ratings volume: Keepy at 48 against OS Translator's 1. Keepy also leads on iOS requirement (17.6 vs 27.0). OS Translator's advantage is rating (5.0 vs 4.8). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Keepy sells 5 in-app purchases, starting at $4.99 per month and OS Translator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
OS Translator holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Keepy has 48 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Keepy ships an update weekly, OS Translator every 8 days. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
