WaySync-M, which is the short for WaySync-Mobile, is a mobile tool for real-time diagnosis and performance evaluation of traffic signal timing plans. It enables users to develop virtual signal controllers on their mobile devices, which run the same timing plans as that running in the field. Together with its advanced features of geo-referencing and dynamic time-space diagram, it allows users to easily diagnose common issues with actuated coordinated signals, such as phase early return, transition, clock drifting, and erroneous offset inputs. It can be used as a supplemental tool for better timing coordinated traffic signals. Dynamic time-space diagram with Integrated vehicular trajectory for best diagnosis and performance evaluation of coordinated traffic signals. Key features: + Display real-time Time-Space Diagram (TSD) of the traffic signals + Display real-time traffic signal timing on Map + Check bandwidth and attainability when edit timing in TSD + Record GPS tracks and videos which can help engineers to improve traffic performance + Support optimization for non-common cycles * Wifi-only iPad cannot record GPS tracks without external GPS device. ## Key features - Real-time Time-Space Diagram display - Real-time traffic signal timing on Map - Check bandwidth and attainability in TSD - Record GPS tracks and videos - Support optimization for non-common cycles - Develop virtual signal controllers ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | One month Pro WaySync-M | $499.99 | one-time | ## Frequently asked questions about WaySync ### What is WaySync-M used for?

The record button and the four icons are back to their normal size and much easier to tap. • The floating map and video preview windows now sit flush against the control buttons, with no leftover gap. • iCloud Drive: your synced projects now appear in the Files app and on iCloud.com. Files were always syncing correctly — they simply weren't visible outside the app. • The iCloud folder is now named WaySync-M, matching the app. Your existing files stay exactly where they are; only the folder title has changed. • Tidied up the app's document folder so it lists only your own project files. • Fixed GPS trajectories not showing on the Time-Space Diagram when Location Shift is enabled. ### 2.9.22 — 2026-08-01 • Updated our free license policy and improved the experience after you sign up. • More reliable cloud storage connections, plus stability fixes and improvements. • Fixed: the floating video window no longer shrinks when you rotate the screen. • Camera preview keeps its correct proportions in Split View and in landscape. • Project files are saved more safely. • Various accuracy and stability improvements. ### 2.9.20 — 2026-07-21 This update brings a refreshed experience and a range of improvements across the app. • Modernized interface — We've refreshed the overall look and feel, including the main tab bar and navigation controls, so WaySync-M feels right at home on your device. The interface now adapts automatically to your version of iOS, so its exact appearance may vary depending on the iOS version you're running. • More accurate time handling — Time-Space Diagram playback and GPS trajectory recording are now anchored to the recording location's time zone, eliminating phase-band misalignment when working across time zones. • Better before/after studies — Travel-time and delay metrics now respect your configured stop threshold for more consistent results. • Simpler licensing — You can now request Mobile (and Windows) free trial licenses more easily during registration. • Smoother file handling — Opening .ti / .gps / .xml project files from other apps is now more reliable. • Real-time data collection improvements, along with numerous performance and stability enhancements throughout. ### 2.9.5 — 2026-04-01 This update from Apple will improve the functionality of this app. No new features are included. - Improve the interaction for deleting subsystem timing. ### 2.9.4 — 2026-03-20 - Bug fixes and performance enhensement. ## Apps similar to WaySync | App | Rating | Price | Category | | --- | --- | --- | --- | | [PedApp](https://appshunter.io/ios/app/pedapp/id1462460931) | 5.0 (3) | Free | Utilities | | [EARL : Smart Traffic Light](https://appshunter.io/ios/app/earl-smart-traffic-light/id6450411090) | — | Free | Utilities | | [SpeedCheck Manager](https://appshunter.io/ios/app/speedcheck-manager/id1580635676) | 5.0 (1) | Free | Utilities | | [PedConnex](https://appshunter.io/ios/app/pedconnex/id1462785633) | 5.0 (1) | Free | Utilities | | [AI Traffic Count](https://appshunter.io/ios/app/ai-traffic-count/id6743341415) | 4.5 (13) | Free | Utilities | | [Polara Field Service App](https://appshunter.io/ios/app/polara-field-service-app/id947593465) | 4.4 (16) | Free | Utilities | ## Related topics [echallan and signal](https://appshunter.io/ios/topics/echallan-and-signal) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
