STL Viewer

Features
Read full description

STL Viewer is a free, offline 3D model viewer for iPhone and iPad. It opens STL, 3MF, OBJ, PLY, OFF, 3DS, GLB and glTF files, measures them, estimates the print, shows them in AR at real size and converts them to STL. Your models never leave your device and no account is needed. AT A GLANCE • 8 file formats: STL, 3MF, OBJ, PLY, OFF, 3DS, GLB, glTF • Works fully offline, with no upload and no sign-up • Free: no subscription and no in-app purchase • No pop-up, timed or full-screen ads; at most one small banner • 17 languages, on iPhone and iPad VIEW IN AR AT REAL SIZE Place your model on a real desk or floor with AR Quick Look and see its true size before you print it. The camera is used only while AR is open. MEASURE AND ESTIMATE THE PRINT • Measure the distance between any two points, in millimetres • See dimensions, volume, surface area and triangle count • Print estimate: weight, filament length, print time and cost, by printer class, material (PLA, PETG, ABS, ASA, TPU, Nylon), layer height, infill and walls • Cut through the model with a section view CONVERT AND EXPORT TO STL Turn an OBJ, 3MF, PLY, OFF, 3DS, GLB or glTF model into a binary STL in millimetres, ready for any slicer. Every triangle of the source is kept, even when the on-screen preview is simplified. INSPECT EVERY DETAIL • Orbit, pan, zoom and fit to screen • Shaded or wireframe, perspective or orthographic • Front, back, left, right, top and bottom views from the view cube • Change the colour and the surface look: plastic, glossy, wood, stone or carbon SHARE • A rotating 360° GIF • A 9:16 video for stories • An STL copy, only when you choose WORKING WITH 3MF 3MF is the format most modern slicers save. STL Viewer reads the geometry inside a 3MF so you can check a part before printing, with real-world units from the file. Modifier meshes and negative volumes are left out, so you see the part itself. A 3MF that holds only print data, such as G-code, says so instead of opening empty. LOCAL AND PRIVATE Models are processed on your device. STL Viewer does not send model files, filenames, paths, geometry or dimensions to any cloud service, advertising provider or analytics platform. WHAT IT DOES NOT DO STL Viewer is for viewing, measuring, sharing and STL export. It does not edit, repair, slice or print models. Textures, materials and animations are not loaded. Native CAD formats (STEP, IGES, SOLIDWORKS, Fusion) need to be exported to STL, OBJ or 3MF first. QUESTIONS AND ANSWERS How do I open an STL file on iPhone or iPad? Tap Open file in STL Viewer, or choose STL Viewer from Open With or Share in the Files app. Is STL Viewer free? Yes. There is no subscription and no in-app purchase. At most one small banner appears after a model is ready. Does it work offline? Yes. Opening, measuring, AR and export all run on the device without an internet connection. Can I open a 3MF from Bambu Studio, PrusaSlicer or Cura? Yes. The part's geometry opens with its real units; print settings and plates are not read. Can I see an STL in AR at real size? Yes. Tap the AR button to place the model in your room at its real size. How do I measure an STL on iPhone? Open the model, tap the ruler, then Measure distance, and tap two points on the model. Can it estimate filament and print time? Yes. Print estimate shows weight, filament length, time and cost from the part's volume and your printer class, material and settings. It is an estimate, not a slicer result. How do I convert OBJ, 3MF or GLB to STL on iPhone? Open the model, tap Export, then Share as STL. How do I open a GLB or glTF file on iPhone? Open it like any other model. glTF files must keep their buffers embedded; use GLB if yours has a separate .bin file. Are my files uploaded anywhere? No. Models stay on your device.

AgentCmd

Features
Read full description

AgentCmd is a native remote control for the Qwen Code CLI's server (qwen serve) that runs on your own computer. Start the server in your project, pair your phone by scanning the QR code it prints, and drive your coding agent from anywhere on your network — or over a VPN or tunnel. It speaks the CLI's own protocol, so the phone shows exactly what the desktop does: • Live transcript — prompts, the agent's thinking, streamed replies, and every tool call as it happens, with token counts and timings. • Approvals on the go — approve or reject file edits and shell commands, with the diff or command right there. Choose how much to auto-approve per session. • Full agent toolbox — switch model and reasoning effort, browse and @-reference files, attach photos or files, and reach Plugins, Channels, Scheduled Tasks, Goals and workspaces. • Pick up any conversation — your sessions are listed newest-first; open one and its history is restored. • Notifications — get told the moment a task finishes, fails, or needs your approval, even while the app is in the background. • Yours end to end — the agent runs on your machine and this app talks only to it. No account, no analytics, nothing sent to us. Access tokens live in the device keychain; unencrypted HTTP is allowed only to local/private addresses. Requires the Qwen Code CLI (Node.js 22+) running qwen serve on your computer. Not sure yet? A built-in Demo shows a complete session offline, no server needed. AgentCmd is an independent client. It is not affiliated with, endorsed by, or sponsored by Alibaba or the Qwen team.

Verdict

The call

The clearest difference is ads: AgentCmd at none against STL Viewer's shown. STL Viewer's advantage is chart position (#191 vs unranked) and update cadence (every 5 days vs every 10 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
