Read full description

This tool shows you the ultimate precise time of day. To achieve this, it uses a special internet time protocol to fetch the time from an atomic time server. We are proud to offer version 5 of the Gorgy Timing Atomic Clock. The program is one of the classic applications since the early days of the Apple App Store and has been continually improved based on user feedback. The Gorgy Timing Atomic Clock shows the precise time of day. To achieve this, it uses a special internet time protocol to fetch the ultimate precise time from cesium atomic clocks available on the internet, or any other time server you like. The graphical display mimics the clock display of the legendary Gorgy Timing clocks, which are used in professional radio and television studios, and we spent much effort to bring the original feeling of these wickedly expensive clocks to your iPhone. This app is used by BBC studios, astronomers, concert promoters, etc. Version 5 contains the following functions: * Universal support for all iPhone, iPad and iPod touch devices running iOS 15, iPadOS 15, watchOS 9 or higher * Optimized for the latest iOS, iPadOS and watchOS, full 64 bit support * Alarm function with snooze (touch anywhere on the screen), volume fade-in, based on weekdays * Alarm time based on seconds (not minutes) * Local time / UTC time mode * Alarm notification window instead of normal alarm sound, if app is not running or in the background * Use playlists or a manual picker selection from your own music library as alarm sounds * The alarm sound is also playing when the device is muted, or the display is switched off, and also works in AirPlay environments * Customizable time server sources * Colors: green, red, blue, yellow, white, dark green, violet, pink, orange, turquoise and hidden, with a separate color option for digits, seconds and segments * Alternative visual display of fractional seconds (1/60th sec. resolution) * 12/24 hours display * Optional second tick sound * Full landscape support (including settings dialog) * Touching the display lets the buttons and status bar fade out * Touching the display again will add the current date (in all orientations) * Disabled screen auto-lock * Options "sync at startup", "hourly", "daily", or a sync button for manual syncing * The last known time delta is used when started without sync * "Night mode", which dims the display using a slider, shows the seconds with only one dot (to prevent a hard brightness switch between second 59 and second 0), switches off the tick sound, and reduces screen updates to save battery * To minimize burn-in effects (especially on the iPhone X OLED display), the clock is doing micro movements when running longer than 5 minutes * VoiceOver support Answers to common questions: * An application can not set your device's system time, so a time sync between the atomic time and the device time is not possible. * If you want to wakeup with music, please do not exit the app before going to sleep (which would result in a local notification dialog without music in the morning), and do not lock your device. Be aware that running an application all the time, even without display, consumes battery, so please make sure that your iPhone is fully charged before you go to bed, connect it to your charger, or use the app's Night mode, which is much more energy-saving.

Offloadr

Read full description

Offloadr backs up footage right on your iPhone and iPad – from card to SSD and NAS, verified and documented. No laptop, no subscription, no cloud. PROJECTS – SET UP ONCE, USE ALL SHOOT Create a project and Offloadr remembers everything that doesn't change: destination drives, verification method, companion files and the shoot day. Next time you open the app everything reconnects – the next offload only needs the card. The shoot day counts up automatically. History is grouped by project, with total size and a combined report per production. If you just want to back up one card quickly, the old path is still there: no project, two taps. EVERY FILE VERIFIED INDIVIDUALLY Offloadr copies each file and then reads it back from the destination. Only when the checksum matches the original does it count as secured. If even one file fails, Offloadr says so clearly – full screen, in red, with the number of affected files and the instruction not to erase the card. You can also have the source read a second time (3-way check). If it differs from the first read, the card or the reader is faulty – a failure a normal verification cannot catch. WRITTEN THROUGH TO THE MEDIUM Offloadr forces every file to physically reach the flash cells before it counts as secured. Without this, a drive reports "written" while the data still sits in its volatile cache – unplugging would lose it. Not switchable, because the entire promise depends on it. HANDOVER PACKAGE, AUTOMATICALLY After every offload the destination holds everything a clean handover needs: • ASC MHL v2 in the "ascmhl" folder – numbered generations, directory hashes and a chain file, exactly as Pomfort Silverstack, YoYotta and Hedge expect • PDF report with file list, checksums, duration, throughput graph and thumbnails • Metadata as CSV and JSON – capture dates, camera details, GPS optional • Complete log of the operation PDF, log and metadata go into the "_Offloadr" subfolder – next to the clips there are only clips. MHL CHECKER Re-verify a backup later: the MHL manifest is read back and every file recomputed. That tells you whether anything on the drive has since been corrupted or went missing while copying on. Manifests from Silverstack, ShotPut Pro or Hedge work too. MORE • Two destinations at once (SSD and NAS) in a single pass • Photos and videos from the Photos app as source, including iCloud download • Incremental: skip files already backed up – for interrupted offloads • Live Activity on the Lock Screen and in the Dynamic Island • Battery and free-space check before starting • Warning when a card was already backed up within the last 24 hours • Proof per history entry: time, device and checksum – detects later modification • German and English VERIFICATION METHODS xxHash-64 by default – the same thing Silverstack, Hedge and ShotPut Pro write. SHA-256 for jobs where a broadcaster or archive requires it. NO CLOUD, NO ACCOUNT Offloadr works entirely on device. No account, no sign-up, no analysis of your footage, no cloud transfer. Your data goes from the card to your drive – nowhere else. REQUIREMENTS A card reader or drive on the USB-C port, or a NAS share mounted in the Files app. Speed is set by your hardware: over 1 GB/s on NVMe via USB-C, more with Thunderbolt on iPad Pro.
