NeoSpectra Scan App vs Proxygen
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
NeoSpectra Scan App
This application allows users to scan and analyze samples using a specialized spectrometer to predict their internal properties. It provides insights into scanned materials, requiring both the hardware scanner and a development license.
- Scan samples with NeoSpectra-Scanner
- Analyze sample properties
- Predict inner material characteristics
- Obtain insights from scanned data
- Requires development license

NeoSpectra Scan App enables you to scan/analyze samples using NeoSpectra-Scanner, in order to predict their inner properties. Analyze, scan, and get insights about samples using Neospectra Scanner. Requires the Neospectra Scanner, the world's smallest FT-IR spectrometer, and a development license.
Proxygen
This tool allows developers to intercept, inspect, and modify HTTP traffic from their iOS devices on a Mac. It offers advanced features like JavaScript scripting for traffic manipulation and a syntax-aware editor for debugging API endpoints.
- Send iOS device traffic to Mac
- Modify proxied traffic with JavaScript
- Match and replace headers/body data
- Syntax highlighting HTTP editor
- WebSocket and SSE message capture
- Local VPN extension for proxying

Proxygen is the best HTTP proxy tool for testing apps and debugging remote API endpoints right on your iPhone, iPad and Mac. And it’s built to delight you while doing it. Features • Send iOS device traffic to remote Mac • Write JavaScript to modify proxied traffic • Store state in variables for use in Editor • Match and replace headers and body data • Test API endpoints with assertions • Transform data with custom recipes • Syntax highlighting HTTP message editor • Message history with powerful filtering • WebSocket and SSE message capture • Store all data in documents SEND TO MAC Easily capture HTTP messages from an iPhone or iPad on your Mac. Traffic is mirrored to the paired Mac over local network even when the iOS app is not active. The Mac app can intercept and edit data of requests and responses before they are forwarded. No more futzing around with Wi-Fi proxy settings and trusted certificates. SCRIPTING Write JavaScript code that modifies proxied traffic. Scripts have access to requests and responses, letting you rewrite headers, URLs and body content, inject data, or implement conditional logic that goes beyond what static rules can express. SYNTAX AWARE EDITOR Edit requests from the message history or create new to any target. All previously sent requests are kept in the project file so you can return to your work later. The editor uses Tree-sitter for fast language parsing and syntax highlighting. It handles decoding of HTTP content automatically, letting you focus on testing the remote API. SERVER GRADE PERFORMANCE The magic lies in a little custom HTTP proxy that the iOS app runs in a local VPN extension. This proxy was developed using SwiftNIO, a framework for bizarrely fast asynchronous network applications. The proxy can perform TLS Manipulator in the Middle (MitM) to see inside HTTPS connections and apply custom logic to each message. To put it bluntly, you’ve probably never seen a HTTP proxy this fast before. And you likely won’t notice that your web browsing is even proxied at all. PRIVACY Proxygen contains no third party frameworks for crash reporting or analytics. Note that Proxygen is a TLS MitM proxy, which means that it sees HTTPS network traffic in plain text. This data is transferred from the proxy to the Proxygen app and stored as part of the project document. Make sure you handle the documents accordingly, as they may contain sensitive data such as session tokens and login credentials.

Verdict
The clearest difference is review sentiment: Proxygen at 83% against NeoSpectra Scan App's 0%. Proxygen also leads on rating (4.3 vs 3.0) and update cadence (every 2 weeks vs every 6 weeks). NeoSpectra Scan App's advantage is in-app purchases (none vs 4). On price, ads, device support and iOS requirement there is nothing between them.
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. Proxygen sells 4 in-app purchases, starting at $2.99 per month. NeoSpectra Scan App asks for nothing beyond the download.
Proxygen holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Proxygen has 18 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 0% of NeoSpectra Scan App's written reviews are positive against 83% of Proxygen's.
NeoSpectra Scan App ships an update every 6 weeks, Proxygen every 2 weeks. The most recent releases landed on September 10, 2026 and September 21, 2026 respectively.
