Noesis AI by Sapiens Qualia is the definitive architectural toolkit for Machine Learning Engineers, Data Scientists, and AI Researchers. Built to eliminate the guesswork in model deployment and hardware provisioning, Noesis provides an offline, lightning-fast suite of calculators and profilers to optimize your LLMs, CNNs, and datasets directly from your iPhone or iPad. Whether you are provisioning GPUs for a 70B parameter model, tracking tensor dimensions through a deep convolutional network, or calculating LoRA parameter reductions, Noesis AI delivers immediate, mathematically precise answers. CORE ENGINEERING TOOLS: • VRAM & GGUF Estimator: Instantly calculate hardware memory requirements for model inference at varying quantization precisions (FP16, INT8, INT4). Estimate exact disk storage space required for quantized GGUF models. • Training Compute Calculator: Estimate total PetaFLOPs required for training runs and map them directly to H100 and A100 GPU hours. • KV Cache Estimator: Provision memory limits based on batch size, context window length, layers, and hidden dimensions. • LoRA Parameter Profiler: Calculate base vs. trainable parameters and analyze memory reduction percentages dynamically. DATA & CODE ARCHITECTURE: • Dataset Profiler: Utilize our high-speed C++ file stream engine to instantly parse massive CSV datasets, returning row counts, column metrics, and structural integrity without sending your data to the cloud. • Math-to-Code Rosetta Stone: Access an offline library translating complex machine learning formulas directly into PyTorch and C++ conceptual implementations. • Tensor Dimension Tracker: Prevent runtime crashes by calculating exact output shapes and receptive fields through multi-layer CNN architectures. • Token Cost Analyzer: Estimate API expenditures for OpenAI and Anthropic models instantly. A TRIUMPH IN ENGINEERING: Noesis AI is not just a tool; it is a masterclass in cross-platform software architecture. • Zero Vendor Lock-In: Driven entirely by a proprietary, universal C++20 mathematical logic core. • Absolute Privacy: No internet connection required. No telemetry. Your configurations, datasets, and calculations never leave your device. • Universal SQLite: Features a fully embedded C-based SQLite amalgamation for the Prompt Library, bypassing host-OS restrictions for absolute data portability. • Native SwiftUI: Experience a flawlessly fluid, responsive interface that adapts natively from the iPhone’s compact screen to the iPad’s expansive workspace. Stop guessing your hardware requirements. Architect your AI with precision. Designed by Sapiens Qualia

Understand your AI and cloud costs without jumping between provider dashboards. API Usage brings OpenAI, Anthropic, and Vercel billing data into one clear, customisable view. Connect multiple organisations, choose the metrics and time ranges that matter to you, and keep important totals visible on your Home Screen. BUILD YOUR DASHBOARD - Track daily spend across configurable time ranges - Break down costs by project, service, API key, workspace, or model - Choose list, bar, line, area, or donut chart styles - Create compact or detailed tiles for each organisation CHECK COSTS FROM YOUR HOME SCREEN - Turn any dashboard tile into a widget - Choose the organisation and metric for each widget - Use small, medium, or large widget layouts - Keep snapshots updated in the background when iOS allows MADE FOR MULTIPLE PROVIDERS - Connect more than one organisation per provider - View OpenAI, Anthropic, and Vercel independently - Add, edit, or remove organisations at any time YOUR CREDENTIALS STAY ON YOUR DEVICE Credentials are stored in the iOS Keychain. API Usage communicates directly with the provider you connect and does not send your credentials or billing data to a Barolo AI server. API Usage is an independent product and is not affiliated with, endorsed by, or sponsored by OpenAI, Anthropic, or Vercel.

Verdict
The clearest difference is iOS requirement: Noesis A.I. at 17.0 against API Usage's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
