Polycam
Polycam is a mobile and web app that creates detailed 3D models using LiDAR sensors and photogrammetry. It makes professional-grade 3D scanning accessible to everyone from architects to hobbyists. The app offers both free and paid tiers with cloud processing and a model library. While hardware limitations exist, its ease of use and versatile output formats make it a practical tool for various applications.
Product Overview
Polycam Review: Is This the Best Mobile 3D Scanner?
When Polycam launched in 2020, it arrived at the perfect moment. Smartphones were getting LiDAR sensors, and the demand for 3D content was exploding across industries. The founders saw an opportunity to democratize what had been expensive, specialized equipment. Today, Polycam has become one of the most popular 3D scanning apps, with over a million downloads and a growing community of professionals and enthusiasts.
How Polycam Actually Works
At its core, Polycam uses two main technologies: LiDAR scanning and photogrammetry. LiDAR (Light Detection and Ranging) uses laser pulses to measure distances, creating precise depth maps. This is available on newer iPhones and iPads with LiDAR sensors. Photogrammetry, the other method, works by taking multiple photos from different angles and using software to stitch them together into a 3D model. This works on any smartphone with a decent camera.
The magic happens in Polycam's processing algorithms. When you scan an object or space, the app captures hundreds of data points or images. These get uploaded to Polycam's cloud servers where sophisticated algorithms reconstruct the geometry, texture, and lighting. The result is a clean 3D model that you can view, edit, and export in various formats.
Who Should Use Polycam?
Polycam serves several distinct audiences. Architects and interior designers use it to capture existing spaces for renovations and presentations. Real estate agents create virtual tours of properties. Product designers scan physical objects for digital prototyping. Educators and students use it for interactive learning materials. Hobbyists and creators build 3D assets for games, VR experiences, or personal projects. Even archaeologists and preservationists have adopted it for documenting artifacts and historical sites.
Pricing: What You Actually Get
Polycam offers a freemium model that's fairly generous. The free version lets you create unlimited scans, but with some limitations: exports are limited to 100 polygons, and you get basic editing tools. The Pro subscription costs $20/month or $199/year and removes all restrictions. Pro users get unlimited polygon exports, priority cloud processing, advanced editing features, and access to the full model library. There's also an Enterprise plan for teams needing collaboration features and custom integrations.
What stands out is the value proposition. Compared to traditional 3D scanners costing thousands of dollars, Polycam Pro at $199/year is accessible. The cloud processing means you don't need powerful hardware on your end - your phone captures the data, and Polycam's servers do the heavy lifting.
The Verdict: Practical 3D Scanning for Most People
After testing Polycam across different devices and use cases, here's the bottom line: if you need quick, decent-quality 3D scans without investing in specialized equipment, Polycam delivers. The LiDAR scanning on compatible devices produces remarkably accurate results in minutes. Photogrammetry mode requires more patience and good lighting but can create detailed models when done right.
The main limitation is hardware dependence. Without a LiDAR sensor, you're relying on photogrammetry which demands more skill and ideal conditions. Processing times can vary from minutes to hours depending on scan complexity and server load. File sizes can be large, especially for detailed scans.
Despite these limitations, Polycam succeeds at its main goal: making 3D scanning approachable. The interface is intuitive, the community is active and helpful, and the output formats work with most 3D software. For professionals who need occasional scans or enthusiasts exploring 3D creation, Polycam offers a practical solution that's hard to beat for the price.
Key Capabilities
LiDAR scanning creates precise depth maps using laser technology available on newer Apple devices. This allows for quick captures of rooms and objects with millimeter accuracy, perfect for architectural measurements and product design. The scanning process takes just minutes and produces ready-to-use 3D models.
Photogrammetry mode works on any smartphone by taking multiple photos from different angles. The app guides you through the capture process with visual feedback, then processes images in the cloud to create textured 3D models. This is ideal for scanning smaller objects or when you don't have LiDAR-capable devices.
360 photo capture lets you create immersive virtual tours by stitching together panoramic images. These can be viewed in VR headsets or embedded on websites, making it valuable for real estate listings and venue showcases. The app automatically aligns and blends images for seamless results.
Free 3D model library contains thousands of user-generated scans that you can download and use in your projects. This community aspect saves time when you need generic objects or inspiration. All models come with proper licensing information and quality ratings.
Augmented Reality integration allows you to place your 3D scans into real-world environments using your phone's camera. This is useful for visualizing furniture in a room before purchase or showing clients how products will look in their space. The AR view maintains proper scale and lighting.
Multiple export formats include OBJ, GLTF, USDZ, and PLY files that work with most 3D software and game engines. You can adjust polygon count and texture resolution based on your needs, from lightweight web models to high-detail renders. Exports maintain material information and UV mapping.
Common Questions
For the best results, use an iPhone 12 Pro or later, or an iPad Pro with LiDAR sensors. These devices provide the most accurate scans through LiDAR technology. Android phones and iPhones without LiDAR can use photogrammetry mode, which requires good lighting and careful camera movement. The web version works for viewing and editing existing scans but doesn't support new captures.
LiDAR scans typically achieve accuracy within 1-2 centimeters for objects up to 5 meters away, making them suitable for architectural measurements and product documentation. Photogrammetry accuracy depends on photo quality and overlap, usually within 2-5 centimeters under ideal conditions. For precise engineering measurements, traditional surveying equipment still outperforms mobile scanning, but Polycam works well for most visualization and planning purposes.
Yes, models you create with Polycam belong to you and can be used commercially. The Pro subscription specifically grants commercial rights. However, models downloaded from the community library may have different licenses - always check individual model terms. For sensitive projects, ensure you have permission to scan locations or objects, as privacy and intellectual property laws still apply to 3D captures.
Processing times vary by scan complexity and server load. Simple LiDAR scans of small objects typically process in 2-5 minutes. Photogrammetry scans with 50-100 photos might take 10-30 minutes. Large architectural scans or complex objects with hundreds of photos can take several hours. Pro users get priority processing, which can cut wait times significantly during peak usage periods.
The free version allows unlimited scans but limits exports to 100 polygons and offers basic editing tools. The Pro subscription ($20/month or $199/year) removes polygon limits, adds advanced editing features, provides priority processing, and includes full access to the model library. Pro also offers commercial usage rights and higher resolution exports suitable for professional applications.
For LiDAR scanning: move slowly and steadily around the object, maintain consistent distance, and ensure good lighting. For photogrammetry: take overlapping photos from all angles (70-80% overlap between shots), use diffuse lighting to avoid harsh shadows, avoid reflective or transparent surfaces when possible, and keep the camera focused on your subject. Both methods benefit from using a tripod for stability and scanning in sections for large spaces.
