iPerfman vs DeckVision
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
iPerfman
This utility measures maximum achievable bandwidth on IP networks across Apple platforms. It offers a beautiful speedometer and speed chart, allowing for LAN testing and advanced parameter adjustments to simulate network conditions.
- Bandwidth measurement
- Speedometer and speed chart
- LAN network testing
- Customizable test parameters
- UDP mode performance testing
- Bandwidth limiting simulation

iPerfman measures network performance between your device and a compatible iperf3 server. Run TCP or UDP tests on iPhone, iPad and Mac. The free version allows three tests per day; Pro unlocks unlimited tests and advanced controls. Measure and investigate: - Test upload, download or both directions, with separate results for each direction. - Follow throughput in live charts. View UDP jitter and packet loss, TCP retransmissions, and round-trip time when those measurements are available. - Save completed tests with their configuration and interval results, then rerun a test or review its history. - Choose an IPv4/IPv6 interface when running a server, or listen on all interfaces. Unlock Pro with a monthly or yearly subscription, or a one-time Lifetime purchase. Pro adds unlimited daily tests, advanced iperf3 parameters, comparison of saved results, and full report export. The yearly subscription includes a seven-day free trial for eligible customers. Existing Lifetime purchases remain valid. iPerfman uses iperf3 3.21 through IperfSwift. A compatible server or second device is required for a network test; this is not an internet speed-test service. The Apple TV app uses a separate interface and has a different feature set.

DeckVision
This app uses your iPhone's camera to automatically detect and label playing cards in real-time. It allows for manual correction of detected cards and exports your annotated data in a format compatible with machine learning tools. All processing is done on-device for privacy.
- Real-time card detection
- Automatic image capture
- Annotation review and correction
- Create ML export format
- 100% on-device processing
- Browsable image library

DeckVision turns your iPhone into a playing card training data collector. Point the camera at any arrangement of cards, and DeckVision automatically detects and labels each one in real time using on-device machine learning. When detections stabilize, the image is captured automatically -- no tapping required. Every captured image goes into a review queue where you can inspect bounding boxes, correct misidentified cards, and delete false positives before they pollute your dataset. Edits are non-destructive, and you can return to any image at any time. When your dataset is ready, export everything as a single zip file in Create ML object detection format. The archive includes all annotated images, an annotations.json file with bounding boxes and card labels, and a metadata.json file with detection confidence scores and correction history for full provenance tracking. Key features - Real-time card detection with automatic capture when the scene stabilizes - Full annotation review and correction after each scan - Browsable image library with thumbnail grid and detail editing - Create ML-compatible export with annotations and metadata - 100% on-device processing -- no data ever leaves your iPhone - Camera permission managed transparently, revocable at any time DeckVision is built for machine learning practitioners, researchers, and anyone working to improve playing card detection models with real-world, human-verified training data.

Verdict
The clearest difference is rating: DeckVision at 5.0 against iPerfman's 4.5. DeckVision also leads on in-app purchases (none vs 2) and update cadence (every 4 days vs every 3 weeks). iPerfman's advantage is ratings volume (4 vs 1) and device support (5 vs 1). On price and ads there is nothing between them.
