Relativity Widget allows you to visualise Einstein's theories of relativity right on your home screen. Two modes : • Special Relativity: imagine that you are in a spaceship travelling at a chosen speed. If you travel fast enough, time will pass differently on earth... • General Relativity: you are on earth while a friend of yours went on a journey, in a spaceship, at a chosen distance to a Schwarzschild black hole. If you are close enough, time will pass differently in the spaceship... Relativity Widget clocks represent the difference in time flow, since midnight, between a high speed / high gravity experiencing reference frame and a low speed / gravity one, according to Einstein's theory of relativity.

About

VaultPony

Features
Read full description

VaultPony creates and opens encrypted containers on iPhone and iPad. A vault is a single encrypted file that holds a private filesystem, and only your password opens it. The containers are compatible with VeraCrypt, so you can open the same vaults on the desktop and back. There is no account, no cloud, and no network access. Your vaults are just files, kept wherever you choose, On My iPhone, iCloud Drive, or a third-party storage provider. Features: Create and open VeraCrypt-compatible containers, with a choice of cipher, hash, and filesystem (FAT or exFAT). Hidden volumes: conceal a second vault inside the first. Two passwords, and the outer one gives no sign the hidden one exists. The outer volume can be write-protected so normal use will not overwrite the hidden data. Header backup and recovery, in-place password change, and keyfiles. Face ID unlock, auto-lock when the app leaves the foreground, a privacy screen that hides vault content in the app switcher, and a no-trace mode that never writes decrypted content outside the vault. A full split-view layout on iPad; browse and preview side by side. Localized in English, German, Spanish, French, Russian, and Brazilian Portuguese. VaultPony is free and open source, built on a shared Rust core you can inspect. It is not affiliated with or endorsed by IDRIX; VeraCrypt is a registered trademark of IDRIX.
