Space Widget brings the universe to your Home Screen. Every day there's a new picture of space, a nebula, a galaxy, a comet or an eclipse, with its story told by a professional astronomer. THE DAILY PICTURE • A new space photograph every day, on your Home Screen and in the app. • Every picture comes with an explanation written by a professional astronomer, and credits the people who made it. • Swipe up to travel back in time through more than 30 years of pictures, all the way to 1995. • Pinch or double-tap to zoom into every detail, and share any picture. • Pull down for new pictures. MADE FOR EVERY SCREEN • Widgets in every size, including extra large on iPad. • On iPad in landscape and on iPhone Duo, the picture and its story sit side by side. • The widget looks right on tinted Home Screens and keeps showing the last picture when you're offline. WIDGET STUDIO Today's picture on your Home Screen is free. Widget Studio adds more: • Put the title or the date on your widget. • Add Lock Screen widgets. • Pin any day you like, or let the widget pick a random picture from the archive. If you bought Space Widget before, Widget Studio is included. • Widget Studio is an auto-renewing subscription, yearly or monthly. The yearly plan starts with a one-week free trial for new subscribers. • Payment is charged to your Apple Account when you confirm the purchase, or when the free trial ends. • Your subscription renews automatically unless you turn it off at least 24 hours before the end of the current period. Renewal is charged within the 24 hours before the period ends. • Manage or cancel it any time in your Apple Account settings. Any unused part of a free trial ends when you subscribe. Pictures and explanations come from Astronomy Picture of the Day. Space Widget is an independent app and isn't affiliated with NASA.

IO

Forget paper checklists. Check I/Os directly on the machine – where sensors and actuators are located. IO-INSPECTOR is an independent third-party tool for commissioning and functional testing in industrial automation environments. With your iPad or iPhone you can observe, document and - if approved, technically permissible and safety-compliant - switch/control signals on site. Less shouting in the workshop, less manual checking and more clarity right where the work takes place. WHY IO-INSPECTOR? • Project and variable import (for TIA Portal® projects): Import variable lists from common export formats (e.g. .xlsx or .csv). IO-INSPECTOR adopts the structure, data types and comments from the file provided - manual re-entry is not necessary. • HMI View Smart Connector: Quickly connect to your system and conveniently access information relevant to commissioning. The Smart Connector is intended to simplify connection and access to the required displays/views in practice - without having to imply an official manufacturer affiliation. • Fast system connection: Detect and connect devices in the local network quickly and clearly. • Live status and targeted control (OPC UA): Connect to compatible controllers via OPC UA and check signals in real time. • Observe: Track changes immediately. OPC is also accessible via the WebSocket protocol. • Control: Set outputs or markers specifically (Force/Modify), provided this is activated in the environment and meets the safety requirements. • Diagnostics: Identify problems more quickly, such as cabling or logic problems. • Digital documentation (PDF): Check off test steps digitally, add notes (e.g. “Sensor defective”, “Adjustment required”) and export a PDF report with your company logo and timestamp. • Filter and search: Filter by status (“Open”, “Done”) or search directly by symbol name. • Mark changes (round-trip support): Mark typos or name adjustments in the app so that you can later apply them in your engineering project in a controlled manner. • Share and collaborate on projects: Share projects so colleagues can continue with the same project status - including testing status and documentation progress (depending on the sharing/export method chosen). TECHNICAL NOTES/REQUIREMENTS • Compatibility: Developed for environments with SIMATIC® S7-1200 (FW 4.0+) and SIMATIC® S7-1500. • OPC UA: OPC UA must be activated on the CPU. Basic access may not require an additional license depending on your configuration; Actual requirements depend on device, firmware and project configuration. • Signals: Supports digital and analog signals (depending on project/export data and target system). • Network/Offline: Use in the machine's local WLAN; Project-related features can also be available without the Internet (depending on the scope of functions). PRICES • Download IO-INSPECTOR for free to create projects and use network scanning. Upgrade options are available for extended functions (e.g. project import, HMI write access (power tags), PDF export, OPC interface, HMI Smart Connector). • Download IO-INSPECTOR and simplify commissioning. Legal notice/trademark: IO-INSPECTOR is an independent third-party software. SIMATIC®, TIA Portal®, S7® as well as S7-1200 and S7-1500 are trademarks of Siemens AG. This app has no business relationship with Siemens AG and is not developed, supported or distributed by Siemens.
