Signal GH is a tool for users of the HDHomerun networked digital TV tuner who want to monitor and improve their Over The Air (OTA) reception quality. It graphs signal quality from multiple channels simultaneously, allowing a user to more rapidly adjust and upgrade OTA receiving hardware, i.e., cables, connections, splitters, pre-amps, and antennas. Snapshot the state of your system using the Experiments tab to keep track of what worked and what didn't work. United States users also have the benefit of a map of digital television broadcasting towers. Depends on the accuracy of your device's compass. If you don't have an HDHomerun, you don't need this product. If you do have an HDHomerun, and use it for over the air reception, you will likely find it useful. If the automatic scan does not find a station you expect, tap on the station's real digital channel in the unused channel column under Settings. Signal GH does not support QAM (digital cable) Please make sure your HDHomerun is set to use a broadcasting channel set and not a cable channel set. You cannot use this software to watch video on your iOS device. This is a diagnostic tool.

Your smart home's batteries, in one place. LoopJuice helps you keep track of battery-powered accessories in Apple Home. Find batteries that need attention, follow their history and plan your next replacement or recharge. KEEP YOUR HISTORY TOGETHER Turn on optional iCloud sync to combine battery history and maintenance information collected on your iPhone and iPad using the same Apple Account. Data stays locally available and syncs through your private iCloud database. Export and import saved data, browse stored history and recover available records. Notification and display preferences remain specific to each device. SEE WHAT NEEDS ATTENTION Browse accessories by room or in a grid, with clear battery rings and the lowest readings first. Search, mark favorites, ignore devices and switch between homes. Low and Critical views highlight batteries needing attention. Unreachable accessories with a last known charge above 15% appear muted and do not increase the attention count or app badge. Warnings and the optional badge cover all your homes. UNDERSTAND BATTERY LIFE Explore history charts with useful 7-, 30- or 90-day ranges when readings are available. See approximate remaining-life estimates from usable history and indications of unusually fast drain. Real charging status is shown when an accessory reports it. Choose whether a battery is rechargeable to set the default for new maintenance entries, without changing its reported readings. REMEMBER REPLACEMENTS AND RECHARGES Record maintenance dates, battery types, quantities, charging methods and notes. Recognizable battery illustrations help identify common types. Reuse details entered for the same manufacturer and model, and compare completed cycles with matching batteries. Work through a maintenance round on iPhone, iPad or Apple Watch, with Undo if needed. WARNINGS THAT FIT YOUR HOME Set a default low-battery threshold or customize it per accessory. Enable battery warnings, silence them for 24 hours or choose Remind me tomorrow for an individual accessory. BATTERIES AT A GLANCE • Widgets for one, two or multiple accessories, battery overviews and batteries running low soon. • Maintenance round, Batteries to prepare, Battery history and Charging list widgets. • Home Screen, Lock Screen and Apple Watch options, with independent home selection where supported. • Siri and Shortcuts for checking batteries and attention items. • Control Center opening controls on iOS 18 or later. • An in-app gallery showing widgets in context and explaining supported sizes. Widget options vary by device and type. The Apple Watch companion shows the latest information received from your iPhone. Made for iPhone, iPad and iPhone Duo, with layouts that adapt as available space changes. Includes light and dark appearances and English, Dutch, Spanish, Portuguese, French and German. No LoopJuice account, ads or third-party analytics. Requires Apple Home access and compatible accessories that expose battery information through HomeKit or Matter. Some report only normal or low status, and charging information varies. Estimates are approximate. iOS manages background updates; continuous monitoring is not guaranteed. Warnings depend on available readings and notification settings. Optional sync requires iCloud and an internet connection; history depends on previously saved or synced readings. Sharing an Apple Home does not share private history between different Apple Accounts. LoopJuice monitors batteries and does not control accessories.

Verdict

The call

The clearest difference is price: LoopJuice at Free against Signal GH's $2.99. LoopJuice also leads on update cadence (every 4 days vs every 4 months) and rating (5.0 vs 4.6). Signal GH's advantage is ratings volume (544 vs 3) and chart position (#86 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
