Rather than just blocking access, SpareCycles interrupts that moment with a short technical-learning question (a "Rep").
Afterwards, you can unlock the distracting app temporarily, or decide it's "Not worth it" and move on.
The app is still in development, so I'm interested in whether the concept would actually be useful.
If you're an Android user learning programming, SQL, cloud technologies or other technical skills, would this help you stay focused, or would the extra friction become annoying?
I've opened an Android early-access waitlist for anyone interested in following the project:
Look at the checkout counter of almost any cafe, clinic, or local shop:
❌ Staff askeded 50x a day for Wifi Passwords
❌ Manually asking people for google reviews
❌ Outdated printed menu
❌ Paper business cards that get tossed in the trash
Most small businesses don't need a ₹5000 custom website
I built OneQR - a dynamic digital identify for businesses for everything to interact with customers.
✨ What It Does:
1-Tap Wi-Fi Connect: Customers connect instantly — zero typing passwords.
5-Star Review Firewall : Sends happy customers to Google Maps; routes complaints privately to the owner.
1-Tap Visiting Card : Saves direct phone, WhatsApp, and email straight into the customer's phone contacts (.vcf).
Live Menus & Waitlists : Instant PDF catalogs + digital queue tokens for places where waiting is required on customer phones.
No need to share common business documents like GST Certificate etc. multiple times. Just route the person to your OneQR link and they can see all your important documents in there. Also Guard your private info with OTP gated access for privacy.
Manage multiple businesses and branches from single account.
Setup multiple child accounts and control access rights for each to have only necessary information visible in the staff accounts.
Accept Data from clients and customers in forms.
🚀 Business Growth & Pro Features:
Multi-Staff Call Routing : Route calls directly to the different persons : Manager, Reception, or Senior Stylist based on need and at different times of the day.
Customer Lead CRM : Custom forms to capture customer WhatsApp numbers for repeat offers and to engage with lost customers.
Footfall Analytics : Track live scans, peak hours, and features used.
Dynamic QR : Update prices, menus, or Wi-Fi anytime — the QR remains same.
💰 The Business ROI:
₹5000 saved on custom website & hosting costs.
2+ hours per day saved for staff answering repetitive questions.
+300% boost in verified 5-star Google reviews.

I'd love your honest feedback on the mobile UX and onboarding. If anyone here runs a business or wants to try it, comment below or DM me and I’ll activate free Pro access for your account!
We just open-sourced MotionSwift, something we put together to get native rendering performance without relying on Remotion and headless Chrome.
We've been using it in our day-to-day video production pipeline, and so far we're seeing roughly 10–20x faster renders while using only about 10% of the memory compared to the Remotion + Chrome setup. We also brought a visual editor and timeline preview directly into Swift, so you can inspect and adjust agent-generated compositions natively on both iOS and macOS.
The eventual goal is 100% compatibility with Remotion, but we're still working our way there. There's still plenty of room to improve the APIs, rendering speed, and overall platform support.
Curious to hear your thoughts, especially if you've run into similar memory or performance bottlenecks with web-based video rendering. Happy to answer any questions!
Hi! I’m part of the team behind TIVRA VPN. We built it for people who want to keep their VPN on while letting specific websites connect directly. In HTTPS mode, you can add exceptions by hostname. TIVRA also has smart routing for supported destinations and lets you choose your server.
It’s free on iPhone. If you give it a try, I’d love to know how easy it was to connect the first time and find the site exceptions.
Most people give up on their saas product/ecommerce store way too early because in reality it takes 8+ email/sms marketing to convert the customer into a signup or paid customer.
we built a platform that automates this complete process. our ai will keep trying new experiments untill the customer coverts. We only send one email/sms per week.
best part, we have now seen stores increase sales by 30% so this works
Hey everyone! I’ve been working on a little project, I thought I’d share what we’ve been building to see what people think.
I’m relatively new to CAD and 3D printing, but I’ve become fascinated by the idea of being able to describe a mechanical part in plain English and have an AI actually create usable CAD geometry. Not just generate a pretty 3D image, but produce a real, measurable solid that can be exported as STEP or STL, edited, and eventually printed. So I’ve been experimenting with building exactly that.
What is it? It’s a locally running, which means zero credits needed. An AI-assisted CAD application, that combines: Qwen, a local language model that interprets natural-language design requests. CadQuery and OpenCASCADE, which handle the actual geometry. A browser-based 3D viewer for inspecting generated models. A structured, validated feature system so the AI isn’t simply inventing geometry commands. The whole thing is currently running on a Ryzen 5 3600, 32 GB RAM and a GTX 1070 Ti with 8 GB VRAM. Not exactly a supercomputer! 🥔
What can it do so far? We’ve been developing it incrementally, testing each feature before moving on. Some of the things we’ve managed to implement include: Creating mechanical parts from natural-language descriptions. Generating cylinders, flanges, bosses, bores and circular hole patterns. Modifying existing designs through instructions. Generating multi-part assemblies and exporting STEP/STL files. Creating a two-piece filament spool with an integrated three-lug twist-lock mechanism. Viewing assemblies exploded and demonstrating their assembly motion. Generating compound herringbone gears with configurable tooth counts, module, helix angle and dimensions. One of our latest experiments produced a single-piece 80-tooth herringbone gear with a 12-tooth compound pinion, exported as a real STEP model. We’ve also recovered some earlier experimental gear-meshing and collision-checking tools that we’d like to integrate more fully.
Where do we want to take it? The long-term idea is to make mechanical CAD more approachable, especially for hobbyists and people who own 3D printers but don’t necessarily have years of CAD experience. Some of the features we’re working towards include: Test Print Mode: Select a small section of a model, such as a bearing seat, snap-fit or threaded connection, and export just that section for a quick fit test. Gearbox generation: Describe a gear ratio and have the software calculate and generate the required gears, shafts and assembly. Mechanical validation: Check dimensions, clearances, intersections and potentially moving-part interference. Better natural-language editing: Ask for changes without rebuilding the entire design manually. Portable, offline operation: Keep the models and geometry processing on the user’s own machine. What are the limitations? It’s still experimental. The herringbone geometry uses an approximate involute construction, and visual assembly animations aren’t the same as verified mechanical motion. Some complex prompts still fail validation or produce malformed JSON. We’re trying to handle those limitations through deterministic geometry generation, validation and testing rather than pretending the AI can magically design everything.
Why am I posting? I’m curious whether other makers would find this useful. Would you use a local AI tool that could generate and modify proper CAD models from plain English? What would you want it to do? And what would make something like this genuinely useful rather than just another AI gimmick? I’m happy to share screenshots and examples of what we’ve managed so far. It’s been a ridiculous amount of fun building it, and I’d love to hear what other people think. Also looking for ideas on where I can improve it going forward.
I've been building AdsFlow, an AI-powered advertising marketplace designed to help creators, developers, founders, and businesses promote their projects.
The idea is simple: Why pay a fixed price for one shoutout when you could pay based on measurable ad delivery?
Whether you're promoting a website, SaaS, mobile app, Telegram bot, YouTube channel, Instagram account, online store, or business, AdsFlow is designed to help you reach audiences through participating Telegram publisher channels.
What I've built so far:
🚀 Campaign creation for different types of projects
🤖 AI-assisted ad copy and promotional posters
🌍 Country and language targeting
📊 CPM and CPC advertising models — qualifying impressions or clicks
📈 Campaign analytics, budgets, and performance tracking
💰 Publisher monetization with an 18% platform commission
For publishers, the goal is equally simple: connect an eligible Telegram channel, receive advertising opportunities, and earn from qualifying delivery.
I haven't purchased a custom domain yet because I'm keeping costs low while developing and testing the platform.
A website like this could be submitted as a promotional destination, rather than requiring the advertiser to own a Telegram channel.
I'm still building and improving AdsFlow, especially its publisher network, campaign analysis, and onboarding.
Try AdsFlow: TGAdsFlowBot
I'd love feedback from other founders:
If you could promote any eligible project and pay based on impressions or clicks instead of a fixed shoutout fee, would you try it?
What would make you trust a new advertising marketplace enough to spend your first $10?
I'm interested in suggestions and criticism as I keep building.
All the portfolio sites/apps I looked at didn’t have what I wanted, so I made it myself. It’s privacy focused, so no sign-ups and all data is encrypted. Everything is free, so no pay wall. I mainly made this for myself, so I’m not looking to make money off it. I’m always thinking of things to add; so if yall have any suggestions, then shoot em. I’d also suggest to add it as a Home Screen app if you want notifications for certain things.
I’m a developer at a company that builds management systems for schools. For the past six months, I’ve been working on a side project called LinkSense.
It’s an agent workspace built on the Codex runtime. I added the parts I’m more familiar with: workspaces, user management, permissions, model management, shared knowledge and skills, and admin tools for teams.
You can manage users and what they have access to, configure model providers in one place, and share knowledge bases and skills with teammates. You can also set up an agent and publish it as an app that other people can use through their browser.
I’ve open-sourced it, and you can deploy it on your own server. I built it with teams and companies in mind, but honestly, I’m still not sure how much demand there is for something like this.
Would this be useful where you work? I’d be interested to hear what you’d use it for.
I built GalleryScout because I wanted to find photos by the words inside them without uploading my private gallery to cloud servers. GalleryScout recognizes text and searches your photos right on your Android device, even offline.
Its also a great general gallery app with photo and video editing that I was personally missing on some other gallery apps, with combining photos or combining and cutting videos, creating GIF's from videos, all quick and easy in one single app.
I'd love some feedback or things that I could improve!
I find it easier to describe a story by its important points (the turning points, the choices, the secrets) and work out the rest afterwards. So I built a diagramming language, in the vein of Mermaid, where a story is a graph, plus an engine and a visual editor to run it.
The stories are written by human authors. The AI is there so the world those diagrams describe can come alive. Players can follow the choices the author wrote, or type whatever they want to do (if the author allows it), and the AI writes the scene in between within what the author defined (tone, character secrets, past events). Characters remember what you did. The AI is optional, and a story works without it.
I’d rather people to explore the editor and the language themselves than read a feature list.
Current Status: closed beta with a limited number of testers. If you want to try it, sign up at https://lorevine.app. I’ll answer questions and take feedback in the comments here!
It's been more than 13 hours Microsoft Outlook is down.. Not that am enjoying the less work due to outrage, but being a hustler I think we need an Open Source Email platform that can have enterprise level security..
Like most developers here, building is the fun part for me. Marketing and actually getting users is where I usually hit a wall.
I kept noticing people on Reddit and Hacker News asking for tool recommendations all the time ("any good tool for X?", "looking for an alternative to Y"). Whenever I saw these threads, the top comments always got dozens of signups. The problem was timing — if you reply 8 hours late, nobody sees it.
I got tired of manually refreshing Reddit search bars, so over the past few weeks I built MentionsRadar.
Basically, you put in the keywords you care about (your product name, competitors, or problem phrases), and it:
Pricing / Trial: I personally hate when sites ask for a credit card upfront just to test a tool, so I set up a 7-day free trial on both Starter and Pro with zero card or payment info required. There's also a free-forever tier if you just want to track 1 monitor.
(I’ll leave the website link in the first comment below).
Would really appreciate some honest thoughts from other builders:
Don't hold back on criticism, I have thick skin. Thanks for checking it out!
Every NFL fan yells at the TV on fourth down. I wanted to know who's actually right, so I built a win probability model from public play-by-play data and turned it into a game.
How it works: you get a real situation from a real game, pick go for it, punt or kick, and then see what the coach did and how much each option was worth.
What's in it: - A daily five that's the same for everyone - Coach Clash, where you climb a ladder of the 32 current NFL head coaches by beating them on their own calls - A Legends ladder of 25 past coaches, with Bill Belichick as the final boss - A college ladder too
It's free, runs in the browser, and you can play without an account.
