TFLite LiteRT TensorFlow Test vs Walk Sprite Kit

How fast does your .tflite model actually run on this iPhone? Pick CPU, GPU or Neural Engine. Get real latency and QPS. No Mac, no Xcode project, no Bazel build, no cloud, no account. Open a .tflite file from the Files app, pick an accelerator, run it. A real measurement on the exact device you care about, in about a minute — no Bazel workspace, no benchmark tool built from source. PICK THE ACCELERATOR - Neural Engine — attaches the Core ML delegate, so supported operators run on the Apple Neural Engine - GPU — attaches the GPU delegate, backed by Metal - CPU — the plain interpreter, with a thread count you choose: 1, 2, 4, 6 or 8 One configuration per run: run it, change the delegate or thread count, load it again, compare the numbers yourself. WHAT YOU GET - Latency: mean, min and max, in milliseconds - Queries per second - Total queries completed and total run duration - A query count you set per run, from 50 to 5,000 invocations Mean, min and max time the model inference call only — no pre-processing, no post-processing. Duration covers the whole loop. The screen stays awake during a run. WHAT YOU SEE ABOUT THE MODEL - Every input and output tensor: index, name, shape and data type (uInt8, int32, float16, float32 and the rest) - Model file size and framework - Live app memory usage against the memory available to the app, refreshed while the model runs - A device tab with model identifier, system version, disk space, and the exact TensorFlow Lite runtime version this build links against A MobileNet model ships in the app and loads on launch, so you see a real measurement before importing your own. READ THIS BEFORE YOU TRUST A NUMBER Inference runs on a zeroed dummy input. The app fills every input tensor with zeros and invokes the model, so what you measure is the compute cost of the graph on the accelerator you picked — latency and throughput, nothing else. It is not an accuracy test. It will not tell you whether your model gives the correct answer, and it does not show output tensor values. Ask it "how fast", not "how correct". What it does not do, stated up front: no side-by-side accelerator comparison in one run, no per-layer or per-operator profiling, no result export, no image or real-data input. It opens .tflite files only. PRIVACY Your model never leaves the device. Loading, inspection, inference and timing all happen locally on your iPhone or iPad. No account, no sign-in — your models and your results are never uploaded. TensorFlow Lite is now called LiteRT; the format and the .tflite extension are unchanged.

Walk Sprite Maker is a production tool for creating reference images and underdrawings for character walk animations from 3D models. It does not automatically draw finished pixel art. Instead, it helps you establish body proportions, motion, direction, and camera angle before you complete the artwork yourself. It is designed for pixel artists, indie game developers, and creators of RPG or top-down game assets. BODY TYPES AND MODELS • Six built-in proportions: 2-, 3-, 4-, 5-, 6-, and 8-head characters • Import your own OBJ model • Adjust head, torso, arm, and leg size or length independently WALK MOTION • Choose from 2 to 64 animation frames • Select loop, start-idle, end-idle, or end-before-idle patterns • Fine-tune arm resting angle, arm swing, leg swing, body bounce, foot angle, and head movement • Preview the animation in real time at an adjustable playback speed DIRECTION, CAMERA, AND DISPLAY • Generate a sheet for the current direction or all four cardinal directions • Adjust the top-down camera angle from 0 to 90 degrees and apply yaw correction • Use separate colors for each body part or one uniform color • Switch between sketch, outline, wireframe, silhouette, shadow, and opacity modes • Export with a transparent or white background SAVE AND SHARE • Save sprite sheets as PNG • Export each frame as an individual PNG inside a ZIP archive • Save and load settings as JSON • Store projects, presets, and export history on your device • Share files with Photos, Files, and compatible drawing apps such as CLIP STUDIO PAINT, Procreate, and ibisPaint PRO FOREVER The one-time Pro purchase removes ads and unlocks eight-direction output, including diagonals; custom and high-resolution output up to 4096 px; storage for up to 100 projects, 100 presets, and 100 history items; output templates for padding, frame spacing, columns, and file naming; and advanced sketch customization for grids, line color, line width, and background color. A separate one-time Remove Ads purchase and a discounted Pro upgrade for existing Remove Ads owners are also available. There is no subscription. Important: The app creates guides and source images for artwork. It does not automatically produce finished pixel art.
