Passta is a fully offline password manager for KeePass (.kdbx) vaults. NO NETWORK, NO ACCOUNTS, NO TRACKING Passta contains no networking code at all. There are no servers, no sync service, no analytics, and nothing to sign up for. Your passwords live in a standard, encrypted KeePass file that you control — and they never leave your device unless you move them yourself. YOUR VAULT, WHERE YOU KEEP IT Open vaults in place from iCloud Drive, Dropbox, On My iPhone, or any storage that appears in the Files app. Passta remembers the location and reopens the file securely — it never makes hidden copies. EVERYTHING YOU EXPECT FROM A PASSWORD MANAGER • Open and edit KeePass vaults (KDBX 3.1 and KDBX 4) • Create new vaults directly on your iPhone or iPad • Unlock with Face ID • Fill passwords in Safari and other apps with AutoFill • Strong password generator • Find duplicate passwords • Organize entries with groups and auto-categorization • Key file support for stronger vault credentials OPEN FORMAT, NO LOCK-IN Passta uses the standard KeePass format supported by KeePass, KeePassXC, KeePassDX and many other apps on every platform. Your vault is yours: open it anywhere, today or in ten years. SERIOUS ABOUT SECURITY Vaults are protected by the KDBX 4 format's modern cryptography, including Argon2 key derivation. Biometric unlock keys are stored in the iOS Keychain, protected by Face ID. PRIVACY Passta collects no data. Its App Store privacy label is "Data Not Collected" — because there is literally nothing to collect.

A measuring toolkit for carpenters, builders, and anyone renovating a home. LO BAN RULER — AT TRUE SCALE Three rulers built from the original specifications: 52.2 cm, 42.9 cm and 38.8 cm. Enter a measurement and the app shows which segment it falls into on all three rulers at once. What makes it different: the scale on screen is drawn at true 1:1. One centimetre on screen is one centimetre in the world, computed from the physical size of the device in your hand. A calibration screen using a bank card lets you verify it yourself. Edge mode pushes the scale to the very edge of the display so you can lay an object against it. Two-step plus and minus buttons sit either side of the number field, with hold-to-repeat — no deleting and retyping a long number because you were off by a millimetre. HEADING COMPASS A multi-ring dial built after traditional instruments, read from the outer ring inward. Drawn at high resolution and scaled down, so it stays sharp when you zoom. Two colour sets to choose from. Devices without a magnetometer still work fully: type the heading in and every ring still resolves. CALENDAR Lunar and solar calendar, public holidays, and your own events. Notification reminders, with lunar-date recurrence so annual observances do not drift. MEASURE WITH THE CAMERA No ruler to hand? Point the lens instead: mark two points in the room, the app estimates the distance between them and reads it against all three rulers. Every measurement carries an error band, and the app says plainly when a figure is not firm enough to settle a segment — when the band straddles a boundary, or when one end of the line landed on a surface the app inferred rather than saw. It will not settle on a number it does not trust itself. When you need a firm figure, the physical ruler and the number pad are both still there. Camera access is only requested when you open camera measuring or the compass on camera, and declining locks nothing else. ABOUT Free to download, and the compass on camera is free too. An optional one-time Pro purchase unlocks five professional dial tiers and taking photos while measuring with the camera. No subscription, no ads, no account required. Works offline — every calculation runs on the device. The app collects no data and sends nothing to us or any third party. Buying Pro is handled by Apple's App Store. Details in the privacy policy.

Verdict
The clearest difference is in-app purchases: Passta at none against Lo Ban AR's 1. Lo Ban AR's advantage is iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
