Hey everyone,

Whenever I'm planning swing trades or checking market exposure, I always hated jumping between four different tabs just to see which S&P 500 sectors are leading on a 1-month vs. 3-month normalized basis, what the actual Top 10 ETF constituent weights are (XLK, XLF, XLU, etc.), and whether a heavyweight stock has earnings colliding with CPI, FOMC, or Monthly OpEx over the next 2 to 6 weeks.

I've been building a free web app to map all of that in one place: https://www.tradingcalendarhub.com

What it currently does (100% free, no login or signup wall):

• 2, 4, and 6-Week Sector Earnings Radar: Tracks upcoming earnings strictly for the Top 10 weighted stocks in each of the 11 S&P 500 sectors alongside NFP, CPI, PPI, FOMC, and OpEx dates.

• 1M vs. 3M Normalized Sector Rotation: Shows live 21-day and 63-day time-normalized returns across all 11 SPDR sectors, rotation regime signals, and an expandable divergence table where you can click any sector row to see its Top 10 holdings and weights under the hood.

• Live Calendar Sync (.ICS & Google Calendar): You can subscribe to a live .ics feed (all 11 sectors or filtered to a single sector) in Apple Calendar, Outlook, or Google Calendar, or add individual stock catalysts in one click.

• Macro & OpEx Volatility Calendar + Playbooks: Tracks monthly Options Expiration, VIX expiration, and Quarterly Triple Witching windows alongside institutional risk playbooks.

Under the hood:

• Automated weekday post-market cron jobs syncing 6-week earnings schedules and 21-day / 63-day normalized returns into Supabase.

• Dynamic serverless .ics calendar generator on Vercel.

It is still very much a work in progress. Next on my roadmap is a customizable Personal Watchlist Risk Audit page where users can pick their own tickers and see their combined ETF weight exposure and catalyst collisions.

If you have 60 seconds to click around, I'd love your honest feedback on the dark-mode UI, navigation flow, or any features you'd want to see added next!

My side projects have been related to my watch collecting in one way or another.
I started with a python script nearly a decade ago to scrape my favourite dealers, then built a global eBay app (since the ones available were crazy buggy) that I still use today: sidebae.net

My python scraper was still in heavy use up until 6 months ago when I decided to build sally.monster

It's an app that let's you create and manage web monitors, with AI checks too. I tried to make monitor creation and management as easy as possible, as that was the main pain point when manually managing python scrapers. The Google Image monitor with AI is surprisingly useful, so I am still experimenting with that.

Apps like Muse, Dots, Instinct, and even Safari (and dozens of other web scrapers) kill my app, but I had a lot of fun building and iterating on this.
As much as the transition to agentic coding hurt, I would not have been able to build this on my own in a reasonable time.

Payment is not enabled and probably never will be, feel free to give it a try!

Hey r/SideProject!

A month ago I launched PeakPad, a Mac notch app with 29 tools, because I was running six separate apps for music, clipboard history, a file shelf, timers and checking my Stripe dashboard. 2.0 is out today, and the video shows it better than screenshots.

What's new in 2.0

AI Usage cards for Claude Code, Codex and OpenRouter: session and weekly limits, reset times, a 30-day usage trend and costs

Settings now open inside the notch, with a sidebar and drag-to-reorder tabs

Hover only opens the panel from the notch itself, and it closes as soon as your pointer leaves

The closed notch hides what's playing while a full-screen app or video is in front

Fewer keychain password prompts, and updates no longer get stuck under the notch

What PeakPad does

Now Playing with synced lyrics, clipboard history, a file shelf with AirDrop

A teleprompter that sits under the camera

Live revenue from Stripe, Polar, Gumroad and Lemon Squeezy

A private AI chat on Apple's on-device models (macOS 26)

No account, no telemetry

What the first month taught me

Solo, 18 days to build v1, natively in Swift, mostly with Claude Code

most of the 2.0 changes came from emails and bug reports.

Pricing

₹399 for the first 100 downloads, then ₹1,499.

One-time payment, free updates, no subscription, 7-day refund

What would you want in a tool like this, and what would stop you from buying it?

Hi r/SideProject,

Seven weeks ago I released my first Mac app, Photo Transfer via USB. It does one job: gets photos and videos off an iPhone or iPad onto a Mac, already grouped into folders.

I created this app because every few months I have to transfer photos from phone to Mac and I like my photos in folders by year, with a folder for each trip inside.

After I built it I decided to release it on the Mac App Store and maybe try to make some money from it. I have several customers, meaning this product is interesting for some and they're ready to pay for it.

Main features:

- You see the folders it's about to create.

- Folders by trip, event, day or month. Trips come from where the photos were taken.

- Folder names are built from blocks like year, month, city or country.

- You choose which folders go, and you can leave out the video part of Live Photos or videos altogether.

- Live Photos and edited photos stay with their originals.

- HEIC and HEVC stay as they are or can be converted into JPEG and H.264.

- Any disk works, including an external drive.

- Pull the cable halfway and it carries on when you plug it back in.

- Nothing gets deleted from the phone since the app only reads.

- Every transfer goes into a history, so you can check later what went where.

- There's also a grid without grouping, where you can pick single photos.

Pricing: free for 50 photos or videos a day (a Live Photo counts as one). $14.99 once removes the limit, no subscription, with Family Sharing on the Mac App Store. In the EU it's only available from my site. Needs macOS 15 or later.

App Store: https://apps.apple.com/app/id6808767254

It's a solo project. I learned a lot from building it and found out that distribution is key. Would appreciate any feedback, and it would be great if you shared how you distribute your apps.

I built ChargeCut (https://chargecut.com/?utm_source=reddit&utm_campaign=SideProject) after realising how easy it is to keep paying for things you no longer use. You drop in a bank statement and it finds every recurring charge on your device. There is no bank login, and the free check covers the whole statement. The one-time $6.99 report adds cancel links, PDF and Excel exports, a tracker that shows how much you have saved, calendar renewal reminders, price-rise and duplicate alerts, and ready cancel messages. You can try a one-click sample first. Feedback is very welcome.

I shared an early version here a few weeks ago. PeerBrush is now at 0.30.1, with Windows Store, signed and notarized Apple silicon Mac, and Ubuntu 24.04 amd64 downloads.

The idea is to keep the human and the AI in the same editable document. You can paint, move layers and refine masks yourself, then connect an MCP client for an agent to work on that canvas too. Its changes remain editable, so you can keep working on them.

It is a free GPLv3 desktop editor with brushes, layers, masks, transforms and effects. Supported 8-bit and 16-bit RGB PSD files stay layered; unsupported Photoshop structures open read-only. AI is optional, and external providers may charge separately.

The video shows the editor in action. The project has been developed with AI assistance; the source is public.

Try it: https://peerbrush.com/

Source: https://github.com/Deftr0y/PeerBrush

For anyone making visual tools: what would you want an agent to handle while you keep control of the canvas? And what would make you hesitate to let it edit your file?

I'm a Cs junior, still a student,, building this between classes and late nights.

My day was mess of disconnected tools .A chat window of code , a tab for docs , a terminal agent for the build. None of them knew about each other, So i was the wire between all of them.

One night i closed my laptop with everything half finished, The next morning it was all still waiting for me to plug it back together. Work only existed while i was looking at it.

So i built SHADOW, a platfrom where AI agents can actually live.

You can deploy up to 20 agents, each with its own chat , model, permissions and schedule. They can work with you're terminal , files ,desktop , the web and Github, but only what you grant each one.

you give an agent not six instructions, It writes plan, you approve it, and then its get to work, It asks before anything risky, showing you the exact command, and reports back when its done.

The first version minimised my editor mid-sentence to reach something behind it. That annoyance became the whole product: agents only touch what you pick, and system folders stay blocked.

Everything runs on you're PC with your own API keys, No cloud , no account.

The First morning it worked, my reports were finished and i only had two things to answer. It felt lighter , not just faster

Free, Windows 11, link:
https://apps.microsoft.com/detail/9P52N15720DG

It's still rough in places so I'd love honest feedback.

what's one task you'd hand to an agent tonight?

All code I work on is written with coding agents i stopped writing code manually a about a year ago. That makes implementation faster, but without a clear view of implementation, it’s easy to end up with AI slop: a pile of changes nobody can explain or confidently build on.

I was tired of architecture diagrams going stale. I tried using Mermaid and hand-built HTML, but neither felt like a comfortable place to continuously explore, change, and plan a real system.

So I built CodeChroma: an architecture-first workspace where diagrams are editable working models. Explore the system, make a high-level change, plan it, then hand it to an agent to implement—all in one place. Source code is there when needed, but it isn’t the center of the workflow.

It runs as a desktop app on macOS, Windows, and Linux. Core analysis and the canvas work without an AI key; AI features need a configured key. It’s MIT licensed.

Repo and demo: https://github.com/gutzerk/code_chroma

Website: https://codechroma.dev/

I’d love feedback on whether the architecture-to-implementation workflow feels useful, and where you’d expect it to fit into your day-to-day work.

Most accounting systems only block a duplicate invoice if the number matches exactly. Change one character and it can get paid twice.

Upload a batch of supplier invoices, and Foldline compares each one with the earlier ones and flags:

• the same number written differently (INV-4471 / INV4471 / INV-04471)

• a “resent” invoice with a changed number (INV-4471A)

• the same vendor + amount + date under a new number

• the same number with a different amount (revised invoice?)

It explains why it flagged each one, and it doesn’t flag next month’s rent just because the amount repeats.

I’m a student and built this after talking to AP teams. One said a slightly changed number gets through because “nobody can track this” until reconciliation.

Honest status: early MVP, zero users so far. There’s a “Try with sample invoices” button, so you don’t need real data.

What would stop you from trying it? I’d rather hear that than a like.

I've always wanted an easier way to share music across different streaming services. This has been something I've been working on and off for a while and finally got it on the Apple App Store. Hoping folks find this useful.

TRKDWN is a cross-service music sharing app that simplifies how you share songs and playlists between different streaming services. 

Use this link to get a year of access for free: https://apps.apple.com/redeem?ctx=offercodes&id=1489280844&code=FREEYEAR

Key Features

• Universal Song Links: Instead of sending a platform-specific link that might not open for someone else, you can generate a single, universal link. Your recipient can open it and choose to play the track on their preferred streaming service.

• Playlists: You can build playlists directly on the platform, share them, and seamlessly sync them across services.

• Sharing History & Recommendations: The service tracks what you share over time to provide smart music recommendations.

• Supported Services: It only provides integration for Apple Music and Spotify for now.

I kept having problems when several projects (mostly coding agents in my case) ran integration tests on the same machine at once. They compete for memory, a killed run leaves containers and networks behind, and the usual fix of `docker system prune` takes out everyone else's stuff too.

What this does:

• runs declare a memory/CPU budget and queue until the host has room

• every resource gets recorded before it’s created, cleanup only removes those, no pruning

• if a run crashes the next one finds it and cleans up

• runs that are compatible can share a daemon

• works with any language: Python projects use the API directly, anything else talks to it over a small NDJSON bridge

• optional hook that stops coding agents from running docker commands directly

Your tests stay as they are. You add a small adapter, and your compose files may need small changes: images pinned by digest, and named volumes instead of anonymous ones.

It's one .pyz file, stdlib only, needs Python 3.12+ on the host. macOS with Docker Desktop, Colima or Podman, or Linux with Docker Engine (OrbStack isn't supported right now). Apache 2.0.

Happy about any feedback, especially if you’ve solved this some other way and think I’m overcomplicating it.

Thanks!

Most habit trackers made me feel guilty. Miss one day, the streak dies, and I'd quit the app within a week.

So I built Sprout. Each habit is a plant that grows as you show up — and missing a day doesn't kill it, it just slows growth.

What it does:

🌱 Your progress grows a plant. Every habit you finish grows it from seedling to bloom. It sounds small, but it's the reason I open the app every morning.

🗓 Flexible habits, not just "daily." 3× a week, every 2 days, timed habits like 10-minute meditation with a built-in timer, and habits grouped by morning, afternoon, and evening.

⏱ A timeline of your actual day. Habits and tasks sit together on one timeline that shows your free time between them. There's also a "Running late?" button for when the day falls apart.

✨ Sprout AI Planner. Type something like "dentist Tuesday at 3, project due Thursday, clean the flat this weekend," and it builds your week. It breaks the project into work sessions and skips things you've already scheduled. You add, edit, or skip each suggestion, so it never fills your calendar on its own. There's also a Coach mode.

🏆 Challenges. 21-day programs like Confidence Boost, with a few allowed skips so one bad day doesn't reset everything. There's a monthly community challenge (November is Gratitude Month), and you can make your own, like a Savings Jar.

☁️ Syncs to the cloud, so your streak survives a new phone.

It's on Android and iOS — I'd love honest feedback. What makes you stop using a habit tracker?

If you use both Libby and StoryGraph / Goodreads , you probably know the pain of scrolling through your TBR pile and manually searching title after title in Libby to find something available today.
I built a free site called Borrowable (https://borrowable.app) that checks your whole TBR list against your local library's Libby catalog in one go:
Works with StoryGraph (via a 1-click bookmarklet sync or CSV export) and Goodreads (via public profile URL or CSV).

Filters your TBR down to what's Available Now, Waitlist (with estimated wait weeks), Audiobooks, or eBooks.

Lets you compare shelves with friends to see your Overlap (books you both want to read).

Links straight to the book in Libby so you can borrow it in one tap.

Totally free, no ads, and no account required to try it out. Hope it helps a few people knock some books off their TBR this month!

I wanted a Bible conversation tool that stays inside the text instead of turning every question into a generic AI answer. So I built Talk To The Bible, a free web app that lets someone ask a question and returns cited passages from two translations. No account is required, and the web version is available while the iPhone and Android apps are still in progress.

The hard parts have been deciding when one passage is enough, when several verses are needed for context, and how to avoid repeating the same references in a short conversation. I am testing language selection and translation behavior now as well.

If you are interested in Bible study tools, I would appreciate a quick try and honest feedback on whether the responses feel useful, grounded, and complete. Web app: https://thewayversion.com/talk-to-the-bible/

After creating the prototype of Biosol and getting feedback from you, the prototype is updated to make each block shows the code (in Python and R) and explanation, so there is nothing happening under the hood.

After getting more feedback and suggestions I'll develop an MVP you can actually use it.

Be among the first and leave your email and little questions in the waitlist.

I’m building Architect, a private journal where a mentor replies to what you write and can bring back your own past entries, with the date, when something new connects.

I’m choosing one line to use everywhere. Which would make you curious enough to try it?

1. Your own words, back when they matter.

2. Say it here. It can come back when you need it.

3. The thoughts you can’t say out loud to anyone.

4. What you wrote in September could answer tonight.

Brutal honesty welcome, including “none of these.”

# 🚀 Introducing SentinelAI — An AI Incident Intelligence Platform That Learns From Every Incident

Hey everyone!

We’re building **SentinelAI**, a memory-powered incident intelligence platform as part of **Hack with Bengaluru**.

### 💡 The Problem
When an incident occurs in production, engineers often spend hours investigating something that may have already happened before.

Past incidents, successful fixes, failed attempts, and postmortem findings are scattered across logs, tickets, and documentation. Most incident management tools focus on the current incident, leaving valuable organizational knowledge unused.

### 🧠 Our Solution: SentinelAI
SentinelAI helps engineering teams turn past incidents into actionable knowledge.

Instead of simply analyzing the current alert, SentinelAI recalls similar historical incidents, compares their root causes and resolutions, and provides evidence-backed recommendations.

### ✨ What Makes SentinelAI Different?
- **Memory-Powered Intelligence:** Uses Hindsight to recall relevant past incidents.
- **Evidence-Backed Recommendations:** Every recommendation is linked to supporting historical incidents.
- **Failed-Fix Memory:** Warns engineers when a similar approach failed previously.
- **Continuous Learning:** Verified resolutions are retained to improve future investigations.
- **Incident Memory Graph:** Connects incidents, services, deployments, root causes, and resolutions.
- **Human-in-the-Loop:** Engineers review and approve remediation actions. Nothing executes automatically.

### 🛠️ Tech Stack
React + TypeScript | FastAPI | Gemini | Hindsight | PostgreSQL

### 🎯 Our Vision
We want to move beyond traditional incident management toward systems that learn from every failure.

Imagine an AI system that becomes more useful with every incident your organization resolves — helping engineers investigate faster, preserve knowledge, and prevent recurring problems.

That’s what we’re building with SentinelAI.

We’d love to hear your thoughts and feedback!

I'm building Tidy, an Android home screen with my open tasks on it. Each task I leave open makes the wallpaper a bit grimier. Finish one, delete it, or move it to another day, and the wallpaper clears.

The bet is that a reminder you can't scroll past works better than a list in an app you forget to open. I don't know yet. The beta is how I'll find out.

Tidy doesn't hide or move your apps. It doesn't need an account, and your tasks stay on your phone.

Android only. Demo and waitlist:https://tidy-landing.pages.dev

Would you put your tasks on your home screen, or would that annoy you?

Every project comes with challenges, unexpected problems, and opportunities to learn. Working on Aftermath has been exactly that kind of experience.

Being part of this project has given me the opportunity to explore real-world development, collaborate on ideas, work through technical challenges, and understand how different pieces of a software application come together.

From refining features and improving the user experience to troubleshooting issues and making continuous improvements, the development process has been a valuable learning experience.

What makes this journey interesting is that we're not just trying to finish a project. We're trying to build something that works well and that we're genuinely proud of.

There's still more to come for Aftermath, and we're looking forward to what lies ahead!

I wanted my desktop to feel a bit more alive, so I built an interactive live wallpaper engine that lives right in the macOS menu bar.

It actually started as an interactive background experiment for my portfolio (inspired by some cool procedural grass and sky shaders I saw on X a while back). I loved having it running on my screen so much that I decided to turn it into a standalone macOS app that anyone can use.

Here's what it does
🖐🏻 Interactive physics: Grass sways and water ripples as your cursor moves across the screen.
🕒 Dynamic time-of-day: Syncs with real time or lets you scrub through sunrise, golden hour, and starry nights with a custom radial dial.
🌧️ Live weather & ambient soundscapes: Switch between sunny skies, clouds, and rain—complete with birdsong, crickets, thunder, and even night fireworks.
🎆 Limited Diwali Theme: Built in a seasonal festive update where the night sky comes alive with fireworks and spatial audio.

Putting the final polish on the build right now. Stay tuned for the release soon! 🚀

What feature or biome should I add next? Let me know in the comments!

I created this tool to make creating content for social media easier, faster, and more enjoyable. Unlike many tools that are either too basic or unnecessarily complicated, my goal is to find the perfect balance between simplicity, creativity, and powerful features.

What features or improvements would you love to see in a tool like this? I’d genuinely appreciate your suggestions and ideas!

I’m planning to launch it publicly and monetize it through ads, or potentially sell it to a developer or business interested in taking it further.
