The Home screen shows basic information about the device: the obvious one – the name and model of the device on the top, and the gauges displays battery level and storage space used. The bottom graphs displays the latest values of CPU and RAM consumption, and Wifi usage. (Note: In some devices, a few graphs may be omitted to improve performance).

Device – General

  • Device Name – The Name of the device. It can be changed on your iOS device’s settings panel > General > About > Name.
  • Model Identifier – Device model Identifier. It is used to identify each generation of devices (and sets of configurations). For instance: The iPhone SE is “iPhone 8,4” and the iPhone 6S Plus is “iPhone 8,2”. In some cases, there are some variants of the same generation with different identifiers – the iPhone 7 for instance comprehends the models “iPhone9,1” and “iPhone9,3”.
  • Model Name – It is the common name of the model. “iPhone 5S Global”, “iPhone 5S CDMA”, “iPhone 7 Plus”, etc.
  • Total Storage – Displays the total storage on the device’s SSD. It is usually less than the marketted value. For instance: 55.24 GB in an iPhone 5S 64GB – this difference comprehends the storage that the operating system takes. The same value is shown on the device’s settings panel > General > About > Capacity. Again, the value will not match, as Apple uses the decimal connotation (where 1GB = 1000000000 bytes), and Lirum Info uses the binary connotation (where 1GB = 1073741824 bytes). In an upcoming update, we will let the user choose the desired connotation.
  • Available Storage – Free space available for the user’s Apps, music, photos, etc;
  • Storage in Use – self explanatory;
  • Model Number – Shows the regulatory model numbers for the model identifier. Each model number is a smaller variation or regional sets: The iPhone 5S Global (iPhone6,2) contains model numbers A1457 (UK/Europe/Middle East), A1528 (China Unicom) and A1530 (Asia Pacific). In an upcoming update, the app will display the current model number;
  • Hardware Model – Specifies the internal hardware set of the device. For instance, the iPhone 6S comprehends the N71Ap (Samsung CPU) and N71mAP (TSMC CPU).

Device – Display

  • Size – display diagonal size, shown on the selected unit (metric/imperial);
  • Area – area of the display;
  • Resolution – screen resolution in pixels;
  • Retina Display – is a brand name used by Apple to define a higher pixel density for the displays. According to Steve Jobs, the number of pixels for a Retina Display should be about 300 PPI for a device held at 10 to 12 inches from the eye. Then, the images and text would be so crips, that the pixelations would be not visible to naked eye;
  • Pixels – is the total amount of pixels on the screen;
  • Density – the amount of pixels per inch on the screen;
  • Aspect Ratio – is the proportional relationship between the screen’s width and height;
  • Color Depth – is the number of bits used by the system to represent each single pixel. Earlier devices used less bits, thus being able to represent less colors. (an 8 bit color depth would be able to represent 256 colors, and a 24 bit – also known as “True color” – can represent 16,777,216 color variations;
  • Amount of colors – check the entry above;
  • Contrast ratio – is the ratio of luminescence between the blackest and the whitest pixels possible for a single frame on the device;
  • Display type – the underlying technology of the display;
  • Wide color gamut – it’s the name Apple gave to the DCI-P3 color space (designed as a standard for digital movie projection for the American film industry). Most displays before the iPhone 7 (2016) used sRGB (standard RGB);

  • CPU Name – internal name of the CPU inside the SoC;
  • Cores – amount of CPU Cores inside the CPU;
  • CPU Core Base – Base micro-architecture of the CPU and it’s name. Not to be confused with the SoC: For instance, on the iPhone 7, the SoC (System on Chip) is called Apple A10 Fusion, while the CPU inside this SoC is called Hurricane (and is an ARMv8-A architecture compatible CPU);
  • CPU Actual Clock – clock speed used in the CPU – can be lower than the maximum clock achievable;
  • CPU Maximum Clock – maximum clock achieved on the CPU specifications. Depending on the device, the SoC may set the CPU to this speed if the usage is too high;
  • Manufacturing Process – To be concise, is half the distance between identical features in a semiconductor array – typically between memory cells or transistors depending on the chip. Each lithography process is different from one another, and there is a whole industrial complex designed for each process. Smaller distances lets more components to be integrated into the core die, and usually improves performance, and uses less power, while dissipating less heat;
  • CPU Pipeline Depth – Instruction pipeline size on the CPU;
  • Cache L1 – CPU Caches are hardware memory caches used by the CPU, to reduce the average cost (time and energy) to access data from the main memory. Each level of CPU cache is designed to specialized situations and kinds of data: The L1 (Level 1) cache is usually the more expensive, faster, and closer to the internal CPU processing circuitry – also, it’s designed to cache program instructions and some immediate data. Caches Level 2 and 3 are slower, cheaper and larger – but still they are much faster and more expensive than the device’s main memory.
  • Cache L2 – check entry above;
  • Cache L3 – check entry above;
  • Instruction Set – Is the programming architecture of the assembly instructions recognized by the hardware. Each set consists of native datatypes, instructions, registers, interruptions, exception handlers, I/O operations, etc;
  • CPU Issue Width – Issue width or Window size, is the maximum amount of instruction that can be issued in the same clock cycle. Providing more than one issue width greatly enhances performance along with the pipeline depth;
  • Out of Order Execution – Determine if the CPU has the out-of-order feature. Older processors can only run “In-order” instructions: commonly the original order of the program. The “in-order” paradigm is slower and less effective, as the CPU core stays idle while performing one operation and waits for it’s result. In “Out-of-order”, intelligent queues are used, thus maximizing effectiveness of memory and I/O calls (that are really time expensive) – This feature allows the processor to handle commands based on the availability of input data, rather than by their original order in the program;
  • Designed by – The Company that created the structure and design of the CPU.;
  • Manufacturer – The Company responsible for the manufacture of the SoC. In some cases, multiple companies are in charge of the CPU production – such as Samsung and TSMC for the iPhone 6S and 6S Plus;

  • Memory – Total amount of RAM memory installed on the device – not to be confused with the device storage: (in an “iPhone 7 128GB” , the 128GB determines the storage, not the memory – in this case, this iPhone has 2GB of memory);
  • Memory Clock – memory bus frequency – sometimes higher than the bus frequency;
  • Memory Type – Memory technology. At this time, there are three types of RAM in use: LPDDR, LPDDR2 and LPDDR3. LPDDR – Low Power Double Data Rate, is also known as mDDR – mobile DDR. LPDDR2 is a dramatically revised version, usually with better power consumption and clock speeds, the same applies for LPDDR3;
  • RAM Free – Unused RAM;
  • RAM Active – Memory currently in use by running applications;
  • RAM Wired – Portion of RAM that can’t be moved to the persisted storage. Usually it is the memory used by the iOS and can’t be allocated to other applications.;

This tool performs comparison of device specs: the devices can be chosen on the bar below (tapping the “this device” button on the device selection screen, makes the App to match the current model in hand).

Green are used to show the “better” value (in some cases, it may be the smaller value, like in dimensions as weight, depth, CPU manufacturing process, etc).

Orange indicates the “worse” value in the current comparison.

Red indicates the worse value between all devices.

Tools – CPU Monitor

Even though the iPhone 7 and 7 Plus feature a 4 core CPU, the system never sees all 4 cores: there are 2 sets of cores, one of each usage situation (high usage and high power consumption / low usage with low power consumption). In devices with 3 real simultaneous cores (like the iPad Pro), the tool shows all 3 cores.

The CPU monitor shows a graph with the usage history of all CPU Cores. To show a single graph, instead of one graph per core, go to the Main Menu > Settings > Force One CPU Graph.

Tools – Memory

  • The tool shows the Free Memory in the device. Keep in mind that this is the unused RAM (the real available memory would count the inactive portion as well).
  • The “Boost” feature releases chunks of memory that are in the inactive portion, and forcefully releases them to the “free” portion. If this feature is not being shown on your device, check if it has a working internet connection available. If the option is still not available, feel free to contact us (keep in mind that the boost option is only available on the Lirum Info Full).
  • The “Memory Details” option shows the detailed partition of memory page states (with precise amount of bytes in each section – active, wired, inactive and free). For details on what each type means, check this documentation, on the “Device – System” section.

Tools – Storage

  • The tool shows the amount of Available Storage space in the device. This determines how much data can be stored on the device, in form of photos, music, documents, app, and other files. If the value gets close to zero, consider removing some apps or movies, and use the “Boost” option;
  • The “Boost” feature makes the phone storage to be completely full, so the operating system can send a clear cache signal to all Apps. Each App will then delete their temporary and cache files, and some storage will be released. Keep in mind that the feature is not supposed to be used in a daily basis, as it takes time for the cache files to accumulate. Using the option repeatedly has no effect. If the feature is not being shown on your device, check if it has a working internet connection available. If the option is still not available, feel free to contact us (keep in mind that the boost option is only available on the Lirum Info Full).

The “Storage Details” option shows the precise values of available space in bytes, and all system partitions:

  • /private/var – Mount point for /dev/disk0s1s2 (user’s data partition). This is a bit different from the Filesystem Hierarchy Standard, where it should be at /var, but a symlink placed at /var redirects to this point, giving some compatibility. It is the largest of the two partitions, and stores all iTunes AppStore applications, media, settings, photos, etc. Before version 1.1.3 of the old iPhone OS (now called iOS), all this information were stored in /private/var/root. For security reasons, in iPhone OS 1.1.3, Apple made most applications to run under the user ‘mobile’, and moved all data to /private/var/mobile.
  • /Developer – By default, this folder is empty. Only when you connect your device to XCode, and active the “Use for Development” option, the content of a ‘DeveloperDiskImage.dmg’ is decompressed by /usr/libexec/mobile_image_mounter into this partition.
  • / – Primary hierarchy root and root directory of the entire file system hierarchy.
  • /dev – Device Nodes, common to any Unix/Linux systems. Content is read-only, because it’s files actually do not exist, and are transparently handled by the kernel.

Tools – Battery

  • The tool displays the current charge level of the battery, and some minimum estimations based on that.
  • By tapping “Check Battery Internal Reports”, the detail screen shows the current Battery Wear Level and some detailed information.

Tools – Connection Rate

  • This tool displays the current flow of data on your wireless connection. Each full panel is equivalent to the selected unit displayed on the top (default: MB). If the connection is slower, you can choose to focus on a kB, so any transfer will easily be recognizable. The options for this panel are:
    • Display Options – determines if the App should display both panels (download and upload), or just one of them;
    • Focus Unit – the unit that each full panel is representing. If the “auto” option is selected, the unit changes according to the connection speed;
    • Blocks – amount of blocks displayed for each unit. Available options are 100, 200 and 500 blocks (if the focus unit is a MB, and the selected option is 500 blocks, each block represents 2097 bytes).

Tools – Gyroscope Sensor

  • Shows real time status of the gyroscope sensor data in each axis. The measurement unit is radians / second.

Tools – Accelerometer Sensor

  • Shows real time status of the accelerometer in each axis. The measurement unit is g (where 1g = 9.80665 m/s²)

Tools – Speakers

  • The tool is intended to test the speakers by generating a sound in the selected amplitude and frequency. It also shows the status of the Silent Switch.

Tools – TouchID

  • The tool performs a TouchID verification and reports its result.

Tools – Touchscreen

  • Tests the touchscreen by showing each touch point (their coordinates) and the pressure (if the App is running on a 3D Touch enabled device).

Tools – LCD Colors

  • The tool makes the LCD to display a certain color. To compare the specific color with other devices, it is recommended that the brightness is adjusted to the maximum value. (By tapping on the Hex HTML value of the color, it is displayed in the whole screen).

Tools – Vibration

  • Performs a sample vibration on the device. The test may fail on iPhone 7 and 7 Plus at this time, due to differences on the Taptic Engine API.

Tools – Camera

  • Tests the camera hardware and displays detailed data about the raw image generated (Resolution, pixels, size (as a PNG file), and size as an uncompressed JPG file.
