CriticalPath – Advanced Profiler for Android
I am excited to announce the project I am working on: an advanced mobile app profiler for Android. Its primary purpose is to optimize app performance and make it faster. Additionally, it serves as an excellent debugging tool. The main distinction between existing tools, such as Perfetto and the Android Studio Profiler, is the ability to synchronize the trace with a video recording of your app. This allows you to see the app's UX alongside what's occurring within the app to identify what's causing slowdowns. Another key feature is the ability to click on any slice and view the cross-thread…
CriticalPath – Advanced Profiler for Android launched on February 28, 2024 with 66 votes, #885 of 3,962 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
CriticalPath is an advanced profiler for Android that helps developers optimize app performance and debug issues. It synchronizes performance traces with video recordings of the app, allowing developers to see the user experience alongside internal behavior to identify slowdowns. Users can click on any performance slice to view cross-thread execution paths of function calls, tracing from user actions to specific points. This helps pinpoint performance problems like slow functions, inefficient network calls, and main thread bottlenecks. The tool includes smart code instrumentation designed to minimize overhead.

Make your mobile app faster. Instrument and record a trace in minutes. Syncronize your trace with the app UI video.
Optimize your mobile application for faster performance and enhanced responsiveness. Identify and address performance bottlenecks in your mobile app. Context is key! Understand what’s happening in your mobile app and precisely when it occurs. With CriticalPath, you can record a trace file synchronized with a screen recording of your app’s UI, eliminating the need for tedious searches to pinpoint issues. The critical path highlights the dependencies between functions to identify performance bottlenecks in multi-threaded environments. It allows you to see the order of execution of functions as a result of a user action and identify what is slowing down the response. You don’t need to manually…from crpath.app

An open source performance monitoring tool2024 · github.com · ▲135Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…
Appstat – Process Monitor for Windows2025 · pragmar.com · ▲86Hey HN, I made a Windows process monitor for app developers and advanced end users. I wanted a taskmgr system-level graph view per app. Windows procmon, while capable, has always been tedious to set up (esp. if not used often). That's pretty much the whole idea behind the app--to simplify app-level monitoring, to make it easy. I hope some of you find it useful!
- PNProdscape.net – Map your mobile app2022 · ▲36
Hello HN, Long-time lurker, first-time poster here. I've created a service that creates a "flow map" of your mobile app. Check it out at: https://prodscape.net. The goal is to reduce last-minute regressions, promote holistic discussion, and help develop more ownership within an organization. This is something that I would have liked to have had when I was working at a big company. Some caveats: 1.) Only iOS is currently supported but Android-support will be coming soon. 2.) You need a developer-signed IPA file (see the guide on creating an IPA file here:…
Perforator – cluster-wide profiling tool for large data centers2025 · github.com · ▲78Hey HN! We are happy to share Perforator – our internal cluster-wide profiler with great support for native languages and a built-in AutoFDO pipeline to simplify sPGO builds. Perforator allows you to profile most binaries without having to recompile or adjust the build process. We use it at Yandex to profile each pod inside a large cluster at modest speed (99Hz), collecting petabytes of profiles every day. There's a blog post about it at https://medium.com/yandex/yandexs-high-performance-profiler-.... Inspired by Google-Wide Profiling, we started continuous profiling…
