Hi HN, I am the creator of Exfault. I am building autonomous AI agents that find vulnerabilities in Android apps.I have noticed there are growing number of AI native pentesting tools for web apps but very few for mobile or Android. With more mobile apps being shipped quickly due to vibe coding, I wanted to build an AI native security tool specifically for Android apps.Exfault combines static and dynamic analysis with AI agents using tools like adb,jadx, apktool for static analysis and reverse engineering, frida for dynamic analysis, hermes-dec for React native decompilation.
The AI agents have access to real Android emulators to peform navigation, explore functionality and validate vulnerabilities before reporting them improving both the quality of reports and also the rate of false positives.Instead of uploading an apk or aab, you can simply enter an Android package name (com.example.app), Our backend automatically acquires a compatible build, installs it in an emulator so the agents can test your app.For authenticated testing, you can provide test credentials and the agent will automatically sign in and continue exploring the authenticated attack surface. I&#x27;m also working on a human-in-the-loop login helper for more complex authentication flows involving MFA, Email verification etc.There&#x27;s a free demo available if you&#x27;d like to try it on your own app.I&#x27;d really appreciate your thoughts and feedback!<a href="https:&#x2F;&#x2F;exfault.com" rel="nofollow">https:&#x2F;&#x2F;exfault.com</a>

Hi HN, I&#x27;m an indie dev who built this to settle a long-running argument with my teenage son about who lifts more at the gym. 
I wanted a workout tracker to kept our data side-by-side on a leaderboard, and let us swap training plans without texting screenshots back and forth. 
Nothing I tried did all three without a subscription wall, so I wrote my own.Most of the app is free, it covers the full workout experience and progress tracking with 80+ exercises.
The one-time purchase unlocks multiple plans, custom movements, and the social&#x2F;sharing features, mainly to pay for the infra.The mobile app is React Native via Expo with Expo Router, NativeWind for styling, Zustand for state (every store is user-scoped via an AsyncStorage key prefix so account switches do a clean rehydrate, good way to have several using using the same app), Reanimated for animations, and react-i18next across six locales. 
The core workout loop is fully offline, and a Firebase layer sits on top for optional cross-device sync and the social features. 
Backend is a small workspace of Firebase Cloud Functions v2 that handle cross-user fan-out (friend requests, shared plans, shared movements) with rate limiting and anti-spam in Firestore triggers.Published a few weeks ago, I can proudly but surprisingly see the daily usage increasing.This is my first mobile app since a while (was doing some 10+y ago), keen for any feedback since it gave me the excitement of building some more.Android only for now, iOS to be published soon.

Back in 2019, I was a CS student in Iraq. I taught myself Node.js, React, and TypeScript. Then in 2020, the pandemic started, and honestly, it was perfect timing for me because suddenly a lot of local businesses needed delivery web apps.I was lucky enough to know some of those business owners, and I ended up building 4 delivery apps by myself. I was coding solo, finishing the apps, setting up Docker, deploying everything, and actually getting paid for it while I was still in my second year of college. It felt unreal. I remember telling my parents, “I have my own money now, you don’t need to give me.” It was one of the best feelings in my life.Later, I got an internship at a company, and I was so happy about it. I honestly couldn’t believe I was already working as a developer while still studying.After the internship, I had an idea for a mobile app. I learned React Native in one week and felt really comfortable with it. I started building the app, but eventually it failed and during that time, I managed to get freelance contracts.Then AI came, and suddenly the bar became much higher.I thought maybe I should build a SaaS product, so I tried that too… and failed again. Somehow, after that, I got another remote contract with a different company. Then I landed the biggest contract of my life — my dream job — with a well-known open-source company.The CTO and the team were incredibly kind. At that point, I knew Go pretty well, but mostly for backend REST APIs and CLI tools. Then the CTO gave me a huge task: build a bidirectional gRPC streaming system that could send debugging files from clients on different devices to the server and then stream them into an admin dashboard.It was a massive task.I told him, “Sure, I can do it,” but honestly, I had never worked with a codebase that big before, and I had zero experience with microservices.So during the first week, I bought Udemy courses on microservices and gRPC. I stayed awake all night learning about streaming and diving deeper into Go. I remember one time I literally didn’t sleep for an entire day because I was so focused and excited.That period was probably the happiest moment of my career.I learned so much, got feedback from senior engineers, finished the feature, integrated it with the Next.js dashboard, shipped it, and finally got it merged.And then… that was it.No more tasks.I felt empty after that.Now with AI raising expectations so much, and with me living in Iraq where remote work is basically the only way to work on meaningful projects, the market feels brutally competitive. On top of that, there are fake jobs, agencies wasting your time, and fake opportunities just to make you fill out useless forms.Now I’m sitting here struggling to even get an unpaid role.I contacted people.
Applied to countless jobs.
Contributed to open source projects hoping someone would recognize my work.
Built 3 failed SaaS products.I genuinely feel like I did everything I could.Every single day I try to improve myself and find work, even unpaid work, if it means joining a real established company and growing with a team.But nothing is working.What went wrong?
What did I do wrong?I still love tech. Recently, I even bought a DevOps course because I’m trying to stay relevant and become more than just a full-stack engineer.But honestly, I’m starting to lose the fire that once made me obsessed with learning.And I know this isn’t only my problem. There are thousands of people out there trying their best to get their dream job too.It’s difficult.what can I do more?

Peak unemployment for a software engineer. What did I do wrong?

I built Opencom, an open-source alternative to Intercom for customer support chat, with knowledge-base and AI support, and mobile apps for push notifications etc.It includes a web widget, agent inbox, customer&#x2F;company profiles, conversations, realtime messaging, AI support and a live demo. The aim is to provide a simple, self-hostable foundation for teams that want Intercom support without being locked into a large SaaS platform.Salesforce has just announced its acquisition of Fin, formerly Intercom, for around $3.6bn. Customer communication is important infrastructure, and I think there should be a credible open-source option.Built with TS, NextJS, React Native &amp; Expo, and Convex backend for easy setup and ability for full self-hosting. Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;opencom-org&#x2F;opencom" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;opencom-org&#x2F;opencom</a>.Appreciate any feedback on architecture, self-hosting setup, and which Intercom-style features people would want before using it in production, along with any other thoughts.It is entirely OSS - no paid features behind a paywall. I hope this could become a community project.

I built an expo-module that makes it easy to integrate CallKit&#x2F;Core-Telecom into a React Native app. I&#x27;ve built a VoIP app before and this was one of the hardest parts. The existing react-native-callkeep is harder to use, isn&#x27;t easy to set up VoIP notifications with and hasn&#x27;t been updated in two years. This new module is tested with the latest versions of iOS&#x2F;Android, Expo and LiveKit. It has a simple and unified API across iOS&#x2F;Android.

Hi HN,My name is Matt and I&#x27;ve been working on a project called Manger, a mobile app used for livestock management. As a child, I grew up in a rural area with chickens, cows and other livestock around me. At the same time, I&#x27;ve always been passionate about technology. About a year ago, I launched Manger on iOS, and, more recently on Android. Just this past week, I launched RFID tags for poultry, called &quot;eFlock Smart Poultry Tags&quot; along with a companion scanner. The &quot;killer feature&quot; of the app is long-range scanning support (up to 15 feet), which can be used to count and identify animals. I imagine it has some other &quot;current&quot; uses, for example, finding young chickens that have been spooked and hiding in grass.The app is written with React Native and uses PouchDB, backed by SQLite. What makes this really neat is that you can sync your data across devices via a (local!) CouchDB server. At my homestead, my wife typically takes care of chickens and records how many eggs we&#x27;ve collected each day. On the other hand, I take care of rabbits and record their weight, as we keep them for meat. All of the data syncs between our iPhones. I currently have a Raspberry Pi setup running CouchDB and it has been working well. The goal for the app is to always be offline-first, with sync and backup functionality backed by on-premises hardware. This is a &quot;beta&quot; feature, as it&#x27;s currently undocumented and I don&#x27;t sell the hardware for that (yet).The eFlock Smart Poultry Tags are passive UHF. It took me quite a bit of time to find a chip &#x2F; antenna combination that has &quot;long rage&quot;, while being &quot;small&quot;. It&#x27;s a trade off. The tags are 45.5mm x 19.5mm x 1mm and are perfectly fine for adult chickens. I think they are fine on young chickens as well - about 8 weeks when they become fully feathered. Tags are 3D-printed with TPU, which makes them flexible and durable. At the time of this writing, nine months into my test on 32 chickens, only one so far has been damaged.The scanner, eScan H103 SE, is sourced from a manufacturer in China. Similar situation as with the tags, it took me quite a while to find something that is &quot;long range&quot; while staying relatively affordable. Depending on make &#x2F; model, livestock scanners (LF&#x2F;HF) range from a few hundred to upwards of a thousand dollars, so the scanner is definitely on the cheaper end of this spectrum.My next upcoming feature are functions for number-type properties. For example, get the totals, average, maximum or minimum number of eggs collected within some specific time frame. Along those same lines, (local!) AI integration where you can simply ask &quot;how many eggs did I collect last week?&quot;.I have quite a few exciting long-term plans as well.Here&#x27;s a video of the scanning feature:

I built MySigner because every mobile release meant juggling Xcode, Fastlane, App Store Connect, the Play Console, plus a $200&#x2F;mo ASO tool and another for reviews. Five things. I wanted one command.So the main piece is `mysigner ship appstore`. It builds, signs, uploads, waits for Apple&#x27;s processing, then submits for review. Same idea for Android: `mysigner ship play-production`. It figures out what kind of project you have on its own (native, React Native, Flutter, Capacitor, Expo). No config file unless your setup is weird.The dashboard does the rest in one place. Screenshot Studio with device frames and translated captions for 30 locales, keyword tracking, reviews from both stores in one inbox, analytics synced daily from ASC and Play.On trust because I know this matters: the build runs on your machine, not mine. Your Apple cert and provisioning profile decrypt only inside your local build, my servers never see them in the clear. Credentials at rest are AES-256. Hosted on Hetzner US, no third-party data brokers. Audit log is hash-chained on the Team plan.Stack is Rails 8 with Hotwire and Tailwind. CLI is a Ruby gem, install with `gem install mysigner`.Pricing: free tier ships to TestFlight unlimited, full CLI, 1 app. Pro is $12&#x2F;mo for 10 apps with ASO and reviews and analytics. Team is $49&#x2F;mo with SSO and audit log. 14-day Pro trial, no card.Platform-wise, iOS shipping requires macOS because Xcode is macOS-only, that&#x27;s Apple&#x27;s constraint not mine. Android works on macOS, Linux, and Windows. The CLI has no native extensions so `gem install mysigner` works wherever Ruby 3.2+ does. I&#x27;ve mostly tested on macOS though. If you try it on Linux or Windows I&#x27;d really appreciate hearing if anything broke.Fastlane is honestly still the right tool if you&#x27;ve spent months tuning your Fastfile or need self-hosted CI in your own VPC. This is for indies and small teams who&#x27;d rather type one command than maintain a release pipeline.I could really use feedback. Bugs, weird workflow stuff, anything that doesn&#x27;t make sense. Limited time and limited team so any criticism is gold.Thank you :)

Hello everyone, I have been working on this for a year and it is such a difficult problem. mobile-ink is an open-source mobile infinite drawing canvas. There is not a strong open-source drawing engine beyond toy demos. Thus, mobile-ink aims to solve this problem and provide a state-of-the-art mobile note-taking canvas package.mobile-ink uses native Skia&#x2F;Metal to address issues with native rendering, pencil latency, eraser behavior, page virtualization, preview caching, memory stability, page interactivity, etc. It has many advanced features such as shape-snapping, primitives to integrate figures, custom backgrounds, pdf import, stroke selection, smooth zoom&#x2F;scroll, and more.The package is iOS + React Native as of now.

My friend and I are working on a CLI tool called fip-cli in Dart.Our aim is to automatically do the tedious tasks involved in setting up a Flutter project. Even though there exist some alternatives, our long term vision is to build something like the React Native&#x27;s Ignite CLI, but for Flutter.At the moment, we are at a very early stage of development and not yet ready to publish anything on pub.dev. We want to get our architecture just right before doing that, which is why we wanted to share it here for feedback.Repo: https:&#x2F;&#x2F;github.com&#x2F;cKalens&#x2F;fip-cliWould be happy to hear any thoughts about the architecture, code, or concept in general. Any feedback on our CLI design in Dart or any language would be greatly appreciated.

Expo’s new `expo-age-range` module wraps Google’s Play Age Signals API on Android and Apple’s Declared Age Range framework on iOS, exposing `age-range` requests to React Native developers.It’s intended to help apps comply with age-assurance laws (e.g. in Texas, Utah, Louisiana). The module is in alpha.

Expo adds AgeRange module wrapping Apple and Google age-verification APIs

Yes, exactly. We also have iOS and macOS targets, so a direct competitor to React Native as well.

# This is a Expo Framework

Expo is a framework and a platform for universal React Applications. 
It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy,
and quickly iterate on iOS, Android, and web Apps from the same JavaScript/TypeScript codebase.

# Requirements

- Node.js LTS release or greater
- Git
- Watchman for macOS users

# Recommended Tools

- VSCode Editor
- Yarn
- Windows users: PowerShell or Bash via WS

# Installing Expo CLI

```bash
 # install the command line tools
 npm install --global expo-cli
```

## Getting Started 

Create a new app:
At this point we should have Expo CLI installed on our development machine and the Expo Go App on an iOS or Android physical device or emulator.
If not, go back to the Installation guide before proceeding.

# Initializing the project

```bash
# Create a project named my-app.
# Select the "blank" templata when promped
expo init my-app

# Navigate to the project directory
cd my-app
```

First, run the development server:

```bash
expo start
# or
npm start
```
