About this app
Core Beacons is a development tool for iOS. Core Beacons lists the advertisements of Bluetooth LE devices in range, as made available to applications by the CoreBluetooth API. Core Beacons lets you explore your "Bluetooth environment" and shows how your iOS device presents this environment to applications. Core Beacons displays general CoreBluetooth information and, if advertised by a device, service and/or manufacturer-specific data. Detailed parsing support is available for • ruuvi sensor tags: • Format 3 (raw data v1) • Format 4 (sensor data encoded in Eddystone URL) • Format 5 (raw data v2) • Eddystone: UID, URL (incl. Physical Web) & TLM frame types • mijia temperature & relative humidity sensor beacons (as far as this protocol is documented) • AltBeacon Core Beacons may be most useful when working with "beacon" type BLE devices.
App details
What you can learn from Core Beacons
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 5 screenshots above are Core Beacons's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Core Beacons runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #FCFCFC) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #3C84FC, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
