PAKEDOU vs BIM Design Lab Studio

PAKEDOU is a simulation app that visualizes network packet flow in real time. Place and connect 14 types of network devices - Router, L2 Switch, Firewall, Load Balancer, NAT, DNS Server, WAF, CDN, and more - on a canvas, and watch HTTP, DNS, ICMP, ARP, and TCP packets flow through your topology with animations. [Who is this for?] - Anyone who wants to visually understand how networks work - Students preparing for CCNA, CompTIA Network+, or similar certifications - Trainers looking for hands-on teaching material for new engineers - Anyone who wants to learn routing, NAT, and VLAN by doing [Two modes for progressive learning] Simple Mode: Packets are delivered just by connecting cables. Routing and MAC resolution are automatic. Even networking beginners can start exploring immediately. Realistic Mode: Simulates real network behavior. Requires routing table configuration, default gateways, ARP resolution (broadcast request -> unicast reply), TCP 3-way handshake (SYN -> SYN+ACK -> ACK), and DNS name resolution. [Educational feedback] When a packet is dropped, the app shows "Why it failed" with an explanation and a hint to fix it. On timeout, a device-type-specific explanation is auto-generated based on where the packet got stuck. [Key Features] - 14 network device types (Client, Server, Router, L2/L3/VLAN Switch, Firewall, LB, NAT, DNS, WAF, CDN, Proxy, Internet) - Color-coded protocol display: HTTP, DNS, ICMP, ARP, TCP - Device configuration (IP/subnet, routing table, ACL rules, VLAN ID, DNS A records, NAT rules, etc.) - Tap a log entry to expand L2-L7 packet details - Manual/auto packet send (choose protocol, source, destination) - Domain-based send (auto DNS query -> HTTP send for real-world flow experience) - SQL injection and XSS attack packets (for WAF testing) - Save/load topology (Free 1 slot / Pro 5 slots) - Playback speed control (0.25x-10x) - Pinch-zoom and pan navigation - First-launch tutorial (6 swipeable pages, each with a built-in Canvas animation) - Starter topology auto-load (Client -> L2 Switch -> Server placed right after the tutorial) - UI in 16 languages (Japanese, English, Simplified Chinese, Traditional Chinese, Korean, Spanish, Brazilian Portuguese, German, French, Hindi, Indonesian, Russian, Italian, Turkish, Thai, Vietnamese) auto-detected from device locale [Today's Outage] Every day, one broken network arrives. Send packets, read the logs, fix the settings, then check your answer. Every challenge is verified by the simulator itself before it is published: it is guaranteed to be broken and guaranteed to be fixable. Inside the day's challenge, Free users can also operate Pro devices (Firewall, DNS Server, VLAN Switch, Load Balancer, WAF). After clearing it, share your move count, hints used and time. Offline, 14 bundled challenges are always available. Story, hints and explanation come in all 16 languages. Pro users can also replay the past 30 days. [Free / Pro] Free: 5 device types, max 5 devices, 1 save slot, with ads Pro (one-time purchase, price shown in the store): all 14 device types, unlimited devices, 5 save slots, no ads, detailed logs, past 30 days of Today's Outage Already purchased? Tap "Pro" in the toolbar, then "Restore Purchase". [Privacy] Topologies you create are stored locally on the device, and the app itself does not send your data to external servers. The Free version displays Unity Ads, whose SDK collects device identifiers and similar data. See our privacy policy for details. Ads are shown only after you choose whether to allow personalized ads on first launch, and you can turn personalized ads off at any time under "?" > "Ad settings".

Learn how professional Building Information Modeling (BIM) actually works — by doing it, not just reading about it. BIM Design Lab puts you through the real workflow MEP and structural engineers use every day: start from one shared building model and build your discipline's systems on top of it, exactly like joining a live, linked Revit project. TEN DISCIPLINES, ONE SHARED BUILDING • Electrical — receptacles, lighting, panels, transformers, and switchboards wired into real branch and feeder circuits • Fire Alarm — initiating devices, notification appliances, control panels, and zone circuiting • HVAC — air handling units, VAV boxes, diffusers, and air distribution zones • Plumbing — water heaters, fixtures, and distribution branches sized by fixture units • Low Voltage / Security — access control panels, cameras, card readers, and door hardware • Data/Telecom — structured cabling, data outlets, wireless access points, and cable bundles • AV — racks, amplifiers, speakers, displays, and audio zones • Fire Sprinkler — fire pumps, standpipes, sprinkler heads, and hydraulic zone demand • Structural — footings, columns, beams, framing bays, and tributary load paths on real grid lines • Architectural — walls, doors, and windows placed directly onto the shared building Every discipline builds on the same levels, rooms, and grids — the way a real MEP or structural engineer links to an architect's central model rather than starting from scratch. A COMPLETE, DETERMINISTIC WORKFLOW • Floor plan canvas — place and wire equipment, room by room, level by level, with color-coded rooms and devices • Distribution trees & riser/framing diagrams — see your equipment hierarchy as a schematic • Schedules — panel, device, fixture, and framing schedules generated live from your actual model, never typed by hand • Load calculations — connected load, demand load, and percent-of-capacity, computed deterministically for every discipline (amps, CFM, GPM, PSF, wattage, or WSFU depending on the trade) • QA/QC engine — a rules-based checker, with its own rule-code namespace per discipline, that flags unassigned devices, overloaded circuits, and missing connections before you'd catch them on a real job • Undo/redo and full project history on every edit LEARN AS YOU GO • A dedicated step-by-step Guide for every discipline, each with a plain-language comparison to how the same step works in professional Revit-based tools • Progress tracking that's actually tied to your work — phases and skills complete automatically as your model reaches real milestones, not by checking a box • An illustration Gallery of BIM and construction-document reference concepts, zoomable and swipeable • Practice tasks that drop you straight into the workspace to try a specific skill WHO IT'S FOR Engineering and architecture students, CAD/BIM drafters leveling up, and anyone curious what a professional multi-discipline BIM workflow actually looks like — without needing an expensive license or a real project to practice on. PRIVATE BY DESIGN • Everything runs on your device • No account, no sign-up required to use what you've purchased • Your project data never leaves your iPhone or iPad BIM Design Lab is a free download. The Architectural guide is free to read. One in-app purchase, All Access, unlocks every discipline's Design workspace and every discipline's Guide — no subscription, no per-discipline pricing, no recurring charges.
