Models Zoo vs DevToolkit
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Models Zoo
Explore and experiment with various AI models directly on your device. This app allows you to chat with language models, generate images, process audio and video, and inspect model performance without needing a server or account. It's designed for developers to easily integrate AI into their own applications.
- On-device AI model catalog
- Chat with language and vision models
- Image generation and manipulation
- Audio processing and speech synthesis
- Model inspection and benchmarking
- Swift code export for integration
- Privacy-focused local inference

Core ML Models is a curated, on-device AI playground. Download any model from the built-in catalog and try it out instantly — no server, no account, nothing leaves your device. Every model is an open-source release converted from PyTorch to Apple's Core ML format and tuned to run efficiently on the Neural Engine, GPU, or CPU. WHAT YOU CAN DO • Chat with small language models (Gemma, etc.) including multimodal vision+text • Generate images from text with Hyper-SD • Remove backgrounds, matte video subjects, and colorize old photos • Estimate depth and reconstruct 3D faces from a single photo • Detect and classify with YOLO, SigLIP, and zero-shot open-vocabulary models • Separate music stems with Demucs and transcribe audio to MIDI with Basic Pitch • Clone voices and synthesize speech with Kokoro and OpenVoice • Super-resolve images with SinSR and RealESRGAN. DEVELOPER TOOLS, NOT JUST A DEMO • Inspect — see every .mlpackage's input/output tensor shapes, data types, compute-unit setting, on-disk size, and Core ML metadata at a glance. • Benchmark — run warmup + timed iterations on your own device and get average / median / min / max latency plus memory delta. Switch compute units (All, CPU+GPU, CPU+ANE, CPU only) to find the fastest config for your hardware. • Swift Code — export a ready-to-paste Core ML loading + inference snippet wired to the model's actual input/output names, so integration into your own app is copy-paste fast. DESIGNED FOR THE NEURAL ENGINE Each model ships with compute-unit settings tuned per-architecture (Neural Engine, GPU, CPU) so you get the best inference speed Apple Silicon can deliver. OPEN AND TRANSPARENT Every model in the catalog links back to its original paper, repository, and license. Conversion scripts are public on GitHub so you can see exactly how the .mlpackage files were produced. PRIVACY FIRST All inference runs locally on your device. The app only fetches model files from public storage over HTTPS — there are no analytics, no ads, and no account to create. REQUIREMENTS • iPhone or iPad with Apple Silicon recommended for best performance • Some large models require several GB of free storage and ≥ 6 GB RAM

A developer's toolkit in your pocket. SSH, SFTP, FTP/FTPS, DNS, Ping, Traceroute, HTTP, WebSocket, SSL and more — all in one app, no accounts, no data sent to the cloud. A single password encrypts everything and keeps it on your device. 13 professional tools, one interface. Native iOS 17 app; no ads, no tracking, no backend. NETWORK DIAGNOSTIC TOOLS • DNS Lookup — A, AAAA, MX, NS, TXT, CNAME records; multiple types in one query • Ping — live latency chart, avg/min/max and packet loss statistics • Traceroute — UDP-based, per-hop latency with reverse DNS • Redirect Checker — follows the HTTP redirect chain step by step; loop detection • SSL Checker — TLS certificate, chain, expiration, cipher suite, SAN list FILE TRANSFER (FTP/SFTP) • FTP, FTPS and SFTP protocol support • Folder upload and download (recursive, including subdirectories) • File permissions (chmod) — numeric mode with preview • Rename, move, copy, bulk delete • Tappable breadcrumb for fast directory navigation • Home icon jumps to the root directory in one tap • Connection details and passwords stored encrypted REMOTE SHELL (SSH) • xterm-256color emulation — top, htop, vim and other screen apps work smoothly • Password, OpenSSH Ed25519 private key, and Secure Enclave-backed P-256 key auth • TOFU host key verification; warns against MITM attacks • Customizable keyboard shortcuts: Ctrl, Esc, Tab, arrow keys, pipe, tilde, slash • Reorder shortcuts by drag and drop • Active SSH sessions stay alive in the background WEB DEVELOPMENT • Built-in browser — WKWebView with Console, Network, and Storage panels • HTTP client — GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS; header editor, JSON/Form/Raw body • WebSocket — connect, send/receive text and binary frames, live log, 500-frame buffer • History for previous requests (HTTP and WebSocket) FILE MANAGER • Local file browser with tappable breadcrumb • Syntax-highlighted code editor: JSON, YAML, Markdown, JavaScript, TypeScript, Python, Bash, HTML, CSS • Image viewer and editor — crop, resize, convert to PNG/JPG/WEBP/HEIC/GIF/ICO, quality control • PDF reader • Media player: MP4, M4V, MOV, MP3, AAC, WAV, MKV, WEBM, AVI, FLV, TS, OGG • Archives: ZIP, TAR, GZIP, BZip2, XZ, 7Z, RAR extraction; ZIP compression • Hardened against archive attacks like zip-slip MEDIA PLAYER (from URL) • MP4, MOV, MP3, M4A, AAC, WAV • HLS live streams (.m3u8) • Custom headers like Authorization and Cookie (HTTPS only) • History of loaded streams NOTES • End-to-end encrypted notes — protected by your app password • Attach photos and files • Attachments open directly in the in-app viewers SECURITY • On-device PBKDF2 (200,000 iterations, SHA-256) and AES-GCM encryption • All connections, passwords, SSH keys, notes, and history stored encrypted • Atomic password change with automatic rollback on failure • Auto-lock — immediate, 1 min, 5 min, 10 min, 30 min, 1 hour • Auto-wipe after too many wrong password attempts (optional; 3, 5, 10, 15, 20) • SSH private keys can be generated inside the Secure Enclave; the key never leaves the device • No data is sent to any cloud. No backend. No account required. WHO IS IT FOR? System administrators, backend and web developers, DevOps and network engineers, and anyone who tinkers with servers and networks. One app, one password, fully local — a professional workstation in your pocket. WHAT CAN YOU DO? • Connect to a remote server via SSH, run commands, tail logs • Transfer files and folders over SFTP, change permissions remotely • Verify DNS, SSL, and redirect chains when launching a new domain • Diagnose network issues with ping, traceroute, public/local IP • Test a REST API, try a WebSocket endpoint • Watch live console output and network traffic in the built-in browser • Download a ZIP archive, extract it, edit the code inside with syntax highlighting

Verdict
Models Zoo and DevToolkit are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
