Press and hold Command to view the available shortcuts. UI: Changed the Pickers in the Overview and Duration sections to use Form-based rather than Wheel-based. CAPABILITY: You can now add custom Protocol Headers CAPABILITY: You can now add a Custom Payload to simulate traffic generator signatures. General: Fixed a couple references in the Help text to obsolete UI elements. ### 2020.8(45) — 2020-10-29 New in PacketCalc 2020.8(45) Enhancements -------------- UI: Completely redesigned the interface for simpler navigation UI: Double-tap any Tile or Slider to copy the raw value to the clipboard UI: Long-press on any Tile or Slider to bring up a context menu to copy that individual Tile/Slider's value as Raw, JSON, or Soulver to the clipboard. UI: Tap on a Tile's value for inline help for that Tile. UI: Added several organizational sections (L1, L2, L1+L2, Duration, Overhead, Throughput, and Packet Overview) UI: Added Payload (bytes) tile UI: Added descriptive labels to Packet Size and MTU selections CAPABILITY: Added 2.5G, 5G, and 200G speeds CAPABILITY: Added several new Packet and MTU Sizes CAPABILITY: Added a "Lock to Size" MTU option Changed -------------- General: Under-the-hood changes for iOS 14 UI: Removed the Tabbed interface in favor of a less complex single-view app interface IU: Decluttered the interface by removing icons/symbols related to packet parameters UI: Removed disclosure chevrons (which revealed/hid controls) in favor of always showing controls for visible tiles UI: Removed Show/Hide Tiles Tab (and functionality) in favor of intelligent auto-tile-selection based on the current packet ### 2020.7(3) — 2020-04-04 New in PacketCalc 2020.7(3) Enhancement -------------- On iPad, added basic pointer effects, including: - Tile and Slider opacity change on pointer hover - Scale disclosure chevrons slightly on pointer hover Changed -------------- Changed the iOS deployment target to 13.4 in order to add pointer onHover() support. This requires that your iPad be updated to 13.4. ### 2020.6(16) — 2020-03-08 New in PacketCalc 2020.6(16) Fixed -------------- Disclosure chevron response to taps is more reliable. Fixed -------------- The ETH II, LLC, and 802.11 buttons disappeared under specific circumstances. Accessibility -------------- In response to requests for larger text sizes for the Headers, Sizes, Speeds, MTU, and IFG selector controls, these are now changed to use Button() rather than Segmented Control Picker(), since Button() allows for resizing text (and other stylings). Enhancement -------------- To gain vertical real-estate, added a Button at the bottom of the Headers, Sizes and Speeds tabs to Show / Hide the lower controls. Enhancement -------------- Header selector buttons are now colored to match their corresponding tiles. Enhancement -------------- To mitigate the disorienting "jumping" effect when protocol Headers are selected and deselected, Tile ordering is changed such that non-protocol Tiles are at the top of the ScrollView. The order is now Calculator Tiles, followed by Parameter Tiles, L1/L2 Tiles, and finally protocol Header Tiles. Enhancement -------------- Added a Calculator Tile group in the Show/Hide Tab Other -------------- - Tweaked colors (again) - Tiles are slightly taller - Removed Share button Icon - Changed Slider button shape to circular ### 2020.5(4) — 2020-02-17 New in PacketCalc 2020.5(4) This release improves handling of Tile Groups, which were introduced in version 2020.4(15). Fixed -------------- The L1/L2 Tile Group indicated it was partially enabled, even when all L1/L2 Tiles were enabled Fixed -------------- Intermittently, on restarting PacketCalc, tapping a disabled Tile Group had no effect. Fixed -------------- When upgrading PacketCalc, renamed internal Tile and Tile Group resources were not properly cleaned up. ## Apps similar to PacketCalc | App | Rating | Price | Category | | --- | --- | --- | --- | | [句子迷](https://appshunter.io/ios/app/id884715640) | 3.9 (8) | Free | Utilities | | [mDNS Utility](https://appshunter.io/ios/app/mdns-utility/id918208340) | 1.6 (5) | $0.99 | Utilities | | [Meck Sheriff](https://appshunter.io/ios/app/meck-sheriff/id917682360) | — | Free | Utilities | | [Send Smart](https://appshunter.io/ios/app/send-smart/id912763740) | 2.2 (10) | Free | Utilities | | [i Sound Level Meter](https://appshunter.io/ios/app/i-sound-level-meter/id912170360) | 4.5 (33) | Free | Utilities | | [TBM 910 Interior](https://appshunter.io/ios/app/tbm-910-interior/id869415980) | 5.0 (2) | Free | Utilities | ## Related topics [ethernet](https://appshunter.io/ios/topics/ethernet) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
