Epson iProjection is a wireless projection app for iPhone®, iPad®, or iPod® touch. This app makes it easy to mirror your device's screen, and project documents and photos wirelessly to a supported Epson projector. [Key Features] 1. Mirror your device’s screen and output your device’s audio from the projector. 2. Project your photos in the "Photos" app, project documents loaded in this app, and project in real-time video from your device's camera. 3. Easily connect your device by scanning a projected QR code. 4. Connect up to 50 devices to the projector, display up to four screens simultaneously, and share your projected image with the other connected devices. 5. Annotate projected images with a pen tool and save the edited images on your device. 6. Control the projector like a remote control. [Notes] • For supported projectors, visit https://support.epson.net/projector_appinfo/iprojection/en/. You can also check "Supported Projectors" in the app's support menu. • While mirroring your device’s screen, video and audio may be delayed depending on the device and network specifications. Only unprotected content can be projected. • Use the mirroring feature to project videos in the "Photos" app. [About Projecting Documents] • The following file types are supported when projecting using "Documents". - Microsoft® Word - Microsoft® Excel - Microsoft® PowerPoint - Keynote - PDF - JPG - PNG - The file types mentioned above are also supported when stored in cloud file services • Depending on the document, the projected image may differ from the image on the computer or at the time of creation, for example, some characters may not be projected correctly. If this occurs, use the mirroring feature ("Mirror device screen") instead. • Animations and screen transition effects, videos, and audio are not played. Use the mirroring feature to play them. • We recommend testing the projection in advance when using this app for presentations. [Using the App] Make sure that the network settings for the projector have been completed. 1. Switch the input source on the projector to "LAN". Network information is displayed. 2. Connect to the same network as the projector from "Settings" > "Wi-Fi" on your iPhone/iPad/iPod touch. 3. Start Epson iProjection and connect to the projector. 4.

About

Shift Assistant

Features
Read full description

Shift Assistant schedules alarms from your roster—not another clock. Enter how you rotate and when a shift starts: 2-on-2-off, morning/swing/night, fixed weekdays, or a custom plant cycle. Wake, leave, and clock-out follow the shift; rest days stay quiet. Weekday schedules can follow national holidays: off on official rest days, still on for makeup workdays. After you change the roster, tap Update alarms. Overnight shifts stay on after midnight, and the clock-out alarm remains. Wake, leave, and clock-out can ring through Silent if you allow alarms; snooze shows a live countdown on the Lock Screen and Dynamic Island. Sleep is a regular notification—tap I’m already asleep if you went to bed early. Home screen widgets show leave countdown and your next shift. Mark plant rest, actual clock-out, or holidays on the calendar.

Verdict

The call

The clearest difference is in-app purchases: Epson iProjection at none against Shift Assistant's 1. Epson iProjection also leads on iOS requirement (15.0 vs 18.0). Shift Assistant's advantage is update cadence (every 4 weeks vs every 6 months). On price, ads and device support there is nothing between them.
