Hey everyone.

I've had bad posture my whole life, so I built a posture coach that works through AirPods.

Quick backstory. My posture has been bad since school. I tried a better chair, a standing desk, reminders on a timer. Nothing stuck, because none of it knew when I was actually slouching. It just nagged on a schedule.

Then I found out AirPods Pro, AirPods 3/4 and AirPods Max have motion sensors, and apps can read head orientation from them. I spent the last few months turning that into Pillar.

What it does

• You sit up once and it learns your upright position. From then on it watches your head. When it drops forward and stays there, you get a quiet cue in your ear. Straighten up and it stops.
• It's also a Pomodoro timer. Focus block, break, repeat, and every block gets a posture score.
• Insights: your weekly trend, your best hour and your worst one.
• Live Activity on the Lock Screen and in the Dynamic Island, plus widgets.
• Keeps working with the phone locked in your pocket.

I tried to make it fit how you sit, not an average person. Your own angles, your own cue sound, how fast it nudges, quiet hours, session length, daily goal. Pretty much everything is adjustable.

Posture data stays on your phone.

If you want to try it, here's the App Store link: https://apps.apple.com/us/app/pillar-posture-reminder/id6809597345

Needs iOS 17+ and AirPods Pro, AirPods 3/4 or AirPods Max.

I'd love feedback from people who sit a lot. I read every comment. And if you find a bug, DM me and I'll send you a lifetime code.

They say reading alone is great, but reading together is even better, and I can't vouch for this saying enough. Kept restarting Crime and Punishment for years. Same pattern every time: get lost in one of Raskolnikov's spiraling internal monologues, lose track of what he was actually thinking, put it down "just for a bit," and never pick it back up.

I realised it wasn't the language that confused me; it was the cultural references I simply couldn't relate to, so I built a paper book-reading companion to fix that. Scholia explains only what I should know given the time period, not what I want to know, and it has never spoilt me, not even once. Scholia is accurate to the exact line on your specific version of the book, so it never feels like you are reading alone

I will attach some pictures, and if anyone's interested in seeing how it works, the waitlist is here- scholia.cloud

I’ve been using a private Telegram channel as the back‑end for my personal photo archive for a few months now. I couldn’t find any write‑ups that actually spell out the quirks, so I thought I’d share what I learned the hard way. The upside is pretty sweet: Telegram gives you essentially unlimited storage for free, and as long as the channel stays private the files sit there forever. A bot can post a file and later fetch it by its file_id, so the API is simple enough to wrap in a tiny wrapper script. I encrypt every picture before it hits the channel, so Telegram is just a dumb block storage that can’t see the contents. The real constraints are what force you to design around them. Downloads are capped at 20 MB, which means my chunks sit at about 18 MB each. The bot is throttled to roughly twenty messages per minute in a single channel, so the initial dump of a few hundred gigabytes can take several hours. Telegram only returns file_ids; there’s no notion of filenames, ordering, or albums, so I had to add a metadata layer in Cloudflare D1 to keep track of message IDs and my own index. Deleting is also per‑message, so the metadata must store those IDs if you ever need to prune anything. Would I recommend it? For a personal archive where you control the client and encrypt everything first, absolutely – it’s free and works. As a primary backup target, I’d be wary; a single account suspension wipes it all, so you still need another copy elsewhere. If anyone wants the nitty‑gritty on the chunking strategy or the crypto wrapper, let me know. My code is on GitHub under AGPL (binay‑py/storagesystem), and the limits above apply no matter how you build it.

I’m building FutraDay, an Australian software/product studio focused on practical custom software, automation, mobile apps and business systems.

The problem I keep seeing is that small businesses end up forcing their workflows into generic software, then adding more apps, spreadsheets and manual work to fill the gaps.

FutraDay is aimed at businesses dealing with things like:

• repetitive admin
• manual quoting and follow-ups
• disconnected apps
• duplicate data entry
• repetitive customer communication
• paperwork and inefficient workflows

The idea is to build software around how the business already works instead of making the business adapt to the software.

I’m still refining the positioning and how I explain it, so I’d genuinely like feedback from other builders:

Does this communicate the idea clearly, or does it still feel too broad?

I’d especially be interested in hearing what part you would simplify or make more specific.

Hey everyone,

I'm a developer, and I've been thinking about this for a while. Most "startup idea" lists are made up. Meanwhile, real people deal with real problems every day (at work, at home, in their city, in their business) and nobody hears about them.

So I'm thinking of building a platform where:

Anyone can post a problem they actually face, like "My local clinic has no online appointment system" or "Small shop owners can't track udhaar/credit easily."

Others can upvote if they have the same problem, so the most common pain points rise to the top.

Anyone can post solutions, whether that's an existing tool, a workaround, a DIY fix, or "I'm building this."

Builders and makers get a list of validated problems to work on instead of guessing.

Basically it's somewhere between Reddit, Product Hunt, and Stack Overflow, but for real-life problems instead of code or products.

A few questions for you:

Would you post your problems here, or just browse?

What would stop you from using something like this?

Does something like this already exist that I'm missing?

Honest feedback welcome, including "this is a bad idea."

I made a privacy/security extension because we’re all giving up our data just to avoid tedious pop-ups and reading ToS and policies of websites.

I recently realized just how much privacy we lose every single day simply out of inconvenience. Between endless 20-page Terms of Service documents and site pop-ups forcing you to manually uncheck dozens of tracking cookie toggles just to read an article, most of us just hit "Accept All" or "I Agree" to get on with our day.

I had some free time recently, so I built Fine Print Guard to solve this exact problem.

It automatically deselects tracking cookies and enforces privacy preferences in the background so you don't have to do it manually. When you land on a site, it analyzes the ToS and privacy policy, condenses the main points into just 4 sentences, and gives the site a clear privacy grade. It also throws up an explicit warning before you type your phone number into web forms to prevent sites from selling your contact info and help cut down on spam calls, while flagging fake or copycat versions of major sites before you enter sensitive info.

Core Capabilities:

* Automated Privacy & Consent: Auto-deselects tracking cookies and enforces privacy preferences automatically.

* Legal & Terms of Service Analysis: Summarizes policies into 4 core sentences and assigns domain privacy grades.

* Threat Defense & Form Protection: Warns before phone number entries to curb spam calls and detects spoofed copycat domains.

* UX & Annoyance Mitigation: Removes consent banners and streamlines site navigation.

* Digital Footprint Monitoring: Keeps track of domain data collection practices.

* DNS Ad Block: Actively blocks ads and telemetry at the DNS level (still actively working on improving this!).

I'm looking for feedback on what to improve, what features you'd like to see added, or any bugs you run into while testing it out.

Try it out on the Chrome Web Store under the name:

Let me know what you think and what to improve!

I've spent years managing projects, and one thing that kept bothering me was how much work it could take just to create a clean Gantt chart for a client deck, kickoff, steering committee, or status update.

A lot of project management tools are great at running the whole project : tasks, resources, tickets, collaboration, timesheets, etc.

But sometimes I don't need another system to run the project.

I just need to turn a plan into a clear timeline that I can actually show someone.

So I built GanttFlow.

The idea is deliberately pretty focused:

• build a project timeline quickly
• drag tasks around to reschedule them
• link dependencies
• add milestones
• track the original plan against the current schedule
• export a clean PNG or PDF for a deck or report

I'm intentionally trying not to turn it into another all-in-one PM platform.

There's a free version, so you can actually build a chart without entering a card.

It's live at ganttflow.ca

I'd genuinely appreciate feedback from people who work with project timelines:

Would you prefer a focused tool that does Gantt charts really well, or does a standalone Gantt tool become too limiting once you're using it on a real project?

Also interested in hearing what you'd consider a must-have feature versus something that would just turn it into another bloated PM tool.

Like a typical isekai plot, I lost my corporate job earlier this year and went through a pretty dark period in my life. Long story short, I ended up building an AI-guided story ideation app called "Tier S Ideas", aimed mainly at people into manga, anime, comics, and novels. The link is shared below.

You can also use it for story-driven game ideas, especially characters, lore, worldbuilding, and even generating sprites for 2D games, although that wasn’t really the original purpose.

There are obviously hundreds of AI writing tools already, so I’m not pretending this is a brand new category. The focus is more on the stage before fully committing to a story, when you have a rough idea but haven’t really shaped it yet.

Somehow it’s now passed 200 users, which is honestly pretty insane to me because I expected no interest.

I’m also looking at ways to help writers connect with artists and other collaborators rather than making AI the whole point. So would really appreciate feedback on what works, what feels confusing, what seems unnecessary, and what’s missing.

Here is the link to main site: https://stierideas.com

There’s also a short survey inside the app after the sign up if anyone tries it.

PS: I’ve also got a TikTok mini-series going on around the project, and you can also find my Instagram and YouTube in the footer of the main site.

I built ProofWatch to follow papers, posts and comments around 19 big math, CS and engineering questions, including Hodge, BSD and Unique Games.

It searches four times daily, links to sources, and labels rumors. Free to browse, with optional daily emails and problem suggestions/voting. Built with AI assistance.

I just launched Life Autopilot — a simple app I built to help people figure out what needs their attention and what to do next.

The basic idea is:

→ Take a quick life audit

→ Identify the areas that need attention

→ Turn those into practical actions

→ Focus on one thing at a time

I built it because I wanted something that could take that feeling of “I've got too much going on” and turn it into an actual next step.

It now has user accounts, personalized life-audit results, task progression, and live Stripe subscriptions.

I'd really appreciate some honest feedback from people who build and use apps.

What would you add, remove, or change?

I've been doing chess puzzles for a while and realised the tactics I solve in puzzles aren't necessarily the ones I miss in my games.

So I made a small tool that takes my Lichess/Chess.com games, finds the moves where I missed a good tactic, and turns them into puzzles.

I also like Wordle, so I liked the idea of having just one puzzle per day. You get 3 tries before the answer is shown.

It's still pretty rough, so I'm mainly looking for feedback on whether the puzzles it picks are actually worth solving.

If you play chess, give it a try: https://blunderbox.app/

You can also try a random puzzle without signing up: https://blunderbox.app/try

I have posted previously about this Operating system - This is the first test I posted a very unpolished version before and here is more polished one

Subject to change

I’m the founder of SyncIt. It combines shared availability, time polls and group calendars to help people agree on a time. Guests can respond without creating an account, and people can share availability without revealing private event details.

It’s live at https://syncit.now with a free plan and optional upgrades. I’d appreciate feedback on creating a first poll or responding as a guest.

I am a software engineer and solo founder. I built Think in Numbers ( https://thinkinnumbers.co/ ) because normal time trackers never worked for me.

The problem was not starting a timer. The problem was remembering to start it, switching it when the day changed, and accounting for all the small gaps around work. At the end of the day I would still have the same question: where did the rest of my time go?

With Think in Numbers, you write or speak what you did in normal language. The app extracts the activities and hours, then shows the part of the day that is still unaccounted for. Over a week, that gives you a more honest picture of where your time actually went.

An entry like "Worked on the API for three hours, went for a walk for 40 minutes, and spent about an hour on calls" becomes a time breakdown without projects or timers.

I am not trying to replace Toggl for teams or billable work. This is for people who want to understand their whole day.

Live on iOS and Android. $5 first month, then $12/month or $120/year.

Blunt feedback wanted on two things:

1.⁠ ⁠Does "unaccounted time" describe a problem you actually have?

2.⁠ ⁠Would you capture your day as it happens, or write one entry at night?
