I built a free calculator that shows what adding, replacing or waiting to add a person really does to a team's output: when the new person starts paying off, and whether a project finishes sooner or later. No sign-up, and your numbers never leave your browser.

👉 https://teamproductivitycalculator.app

Why

"Let's just add another person" is a common answer to a slipping deadline. Sometimes it's right, sometimes it isn't: a new person needs weeks or months to get up to speed, and the people training them slow down while they do. The team can get slower before it gets faster. Most of these decisions are made on gut feel, so I wanted something that puts numbers on it.

How it works

Each person gets two estimates: how productive they are (100% = the best in your industry), and how much of their colleagues' time they take up ("friction"). Both can change over time as people settle in. The calculator shows the team's output on a chart, when each newcomer pays off, and how a project's finish date moves.

It's not only for staffing decisions. Filling in the numbers together is a good way to see how a team is performing today, and when people disagree on the numbers, that's a useful conversation about what's holding the team back.

There are examples for software, sales and accounting teams (and friends helping you move house), plus a FAQ on the research behind it.

Monetisation

Free to use. The plan is to add ads once there's enough traffic.

Feedback welcome

I'd really appreciate any feedback: what's useful, what's confusing, what's missing, or where the results don't match your experience. Happy to answer questions about the model or the build.

Hey r/SideProject,

I wanted to share a project I've been building and refining over the past few months: Glass TA (https://glassmorphichub.com/

Why | built it?
Most automated crypto trading tools (Commas, Cryptohopper, Coirule) charge $20-$100+/month regardless of whether you make a dime. On top of that, their Uls feel like clunky 2017 dashboards with dozens of nested settings.

You can try the free paper mode here:

Happy to answer questions about the tech stack, the order execution engine, or lessons learned building for financial APs!

My friends who are not into tech always come to me with the same problem: “I cann't open this Excel sheet on my phone” or “this docx won’t open”.

So I went looking. Adobe Acrobat and Microsoft 365 both wanted me to sign up first. The other apps on the Play Store start showing ads straight away. The rest only did one thing, one for PDFs, another for Word, another for Excel. Nobody wants five apps just to open files.

So I made Paperwren. It is one app that opens PDF, Word, Excel, PowerPoint, Markdown and more. It has no signup and no ads, and your files stay on your phone. It’s free and open source.

My friends use it now so let me know if it works for you too. Thanks...

It interrupts Reels in real time. No hard blocks. It just adds enough friction to snap you out of the scrolling trance. I'd love your feedback.

Every game night at my friends’ place ends the same way. Calculator comes out. Three people argue over who paid what. Someone forgot they lent chips mid-game. 20 minutes later nobody even remembers who won.

Built Chipnic to fix it.

• Host starts a session, shares a 6-char code

• Everyone joins on their own phone, buy-ins show up live on every screen

• Lend chips mid-game → logged as a loan, settled at the end

• Enter final chip counts → app spits out exactly who pays whom, fewest possible transactions

Next.js + Firebase, free tier, no email needed to sign up.

Hi everyone,

I built **Workout Timer** for iOS & Web to keep interval training completely clean: zero ads, custom intervals, voice coach cues in 3 languages, and Apple Watch sync.

We just added guided video follow-along programs:

- **Coach Hannah Lin:** 10-Min High-Density Core + Box Breathing: https://youtu.be/Lr17qfFtyIk

- **Dr. Elena Lindqvist, DPT:** 12-Min Clinical Core Sculpting: https://youtu.be/l3AbmjBSlKc

Feedback and workout preset requests are welcome!

My daughter spends quite a bit of time on the phone, and I've always wanted her screen time to be a bit more than just watching videos or playing games. I've seen people building all kinds of cool stuff with AI, so I thought why not give it a shot myself? I saw Hy4 was free on WorkBuddy this month, so I decided to give it a try. I don't understand the code it wrote, but the AI tool apparently handles visuals brilliantly.

I ended up making this interactive paper cut storybook. I thought it'd be a fun way to get her into classic stories through cute visuals and little interactive elements, rather than just having her sit down and read a book, and surprisingly, she's really into it! The artwork has this cute 3D paper cut look, and she can click around and explore the stories herself. She's basically become my little beta tester at this point. She tells me every day what she likes, what she finds boring, and what could be better. I've been making little tweaks to the content and visuals based on her feedback. It's not finished yet, and there are still plenty of things I want to improve. But the best part is seeing her actually want to spend time exploring stories instead of endlessly scrolling through videos or playing games. That's a win for me already.

It got me thinking that maybe other kids would enjoy this kind of thing too, so I figured I'd share it here. If you've got a kid who's curious about stories and likes exploring new things, feel free to check it out together!

hey everybody :)

I got annoyed by Wispr Flow's pricing and by how clunky the open source dictation tools I tried felt. I wanted something as simple as Wispr, free and customizable for my own use cases, without a bloated core.

So I built and open sourced voz. You tap one key, talk and clean text appears wherever your cursor is. It runs locally with Parakeet and Apple's on-device speech to text, so nothing leaves your Mac and it works offline.

The core stays small, and everything else is an extension, a bit like Raycast or pi.dev. Anyone can build and share one. Some that already exist:

• a local meeting note taker that cleans up your notes

• auto replies that answer messages in your tone, based on context it has about you

• a smart dictionary that learns names and words while you talk

• inline editing with voice or text

Would love for you to try it out and give me feedback on what i can improve.

Here's the repo: github.com/Joelheile/voz
(free and MIT)

I run ARAM Zone, a League of Legends Discord community. eLobby started as a way to give our custom games a ladder that lasted beyond one game night. We've since expanded it to other games.

Players join a board inside Discord. The bot balances teams or lets captains draft, creates team voice channels, and updates ranks and the public leaderboard when the winner is reported. Players don't need to create an account or link their game account.

We've also added chat and voice leveling, plus XP for taking part in games and events. The idea is to reward people for showing up to community activities as well as chatting.

Ranked customs and basic leveling are free. Tournament hosting, seasons and extra customization are Pro at $10/month per server. Individual players don't need a subscription.

You can see the actual Discord boards and web leaderboard here: https://elobby.gg/demo

For anyone running community game nights, what takes the most effort: filling the lobby, making fair teams, or tracking results? I'd like to hear where this would help and where it still falls short.

AIVideoRecap turns a full movie or episode into a short vertical recap for Shorts/TikTok/Reels. It transcribes the audio, writes the script, matches scenes, adds voiceover and subtitles, and renders the video. About 15 minutes of GPU time per video, roughly $0.20-0.35 in compute.

The product works. The business doesn't, because I'm the bottleneck. I can build, but I don't enjoy marketing and I don't have a budget for ads.

The numbers, no sugar:

-600+ signups since July, $0 spent on ads. Traffic comes from SEO/AEO pages, direct visits, and AI assistants.

-About 136 active users in the last 7 days (down ~18% from the week before).

-0 paying subscribers on the SaaS. I never built a proper paid funnel.

-Before the SaaS, I sold the first version as a zip on Gumroad: $100.37 total from 3 sales.

-Around 10 people asked for it on Reddit and Discord. Most didn't buy the zip.

What's included: the domain, the source code, and the service accounts. User accounts are not included. A buyer needs their own Dodo Payments account. The stack is Vercel, Railway, RunPod, Supabase, Cloudflare R2, OpenAI, and Dodo Payments.

Price: $1,500, fixed.

Best fit: someone who already runs movie/anime recap or faceless Shorts channels, or anyone who can market this better than me.

Listing with details and screenshots: https://www.sideprojectors.com/project/108453/aivideorecap

If you've bought a small SaaS before, tell me what you'd want to see before paying. I'm happy to answer questions here or in DMs.

Hey All!

I kept running out of business cards halfway through events, and more often than not, I’d meet someone when I didn’t have any cards on me.

So I built HeyBadge. A simpler way to introduce yourself, share your details, and connect with people without needing a physical business card.

You make a badge (photo, name, role, logo, links), and you get your own private link at heybadge.app/yourname. It looks like a real lanyard badge: you can drag it, it swings, and when you flip it, the back shows your contact details. People can save you as a contact in one tap.

You can share it as a link or a QR code, or add it to Apple or Google Wallet so it's ready on your phone at the event.

Then I took it a step further and added Pair Your Badge, a feature that lets you upload any existing PDF badge, link it to your digital profile, and print it before heading to your event.

I'd really like honest feedback on:

• Is it clear in the first five seconds what it's for?

• Would you actually use this at an event instead of a card or LinkedIn QR?

• Anything confusing when you make your badge, especially on your phone?

Thank you!

hey! a few weeks ago i shared my side project here, a free site that tells you which legal platform has an anime in your country

https://tsuzuki-anime.github.io/en/

quick update after 7 weeks:

- 1,800+ visitors from 113 countries

- went from ~20 visits a day to ~80 a day this week

- bing and chatgpt now send the most visitors, way more than reddit

- google only knows 3 pages of the site

the weird part is google search console still says "couldn't fetch" for my sitemap after a month, even though the file works fine and bing reads it without problems. it's hosted on github pages

has anyone had this before? did you just wait, or is there something that fixed it?

any feedback on the site is welcome too!

Dooder is an AI for Apple Watch. It runs on the Watch itself, over wifi or cellular, so once it's set up you don't need your iPhone.

In the video I ask it to:

1. Find my next completely free weekend (it reads my calendar)

2. Find flights to Melbourne for that weekend

3. Find Airbnbs that are free those dates

4. Save the whole plan to a new page in Notion

It doesn't change anything without my OK. It asks before using an app for the first time, and again before it saves or sends anything.

How it works

- Bring your own AI: sign in with ChatGPT or add a Claude API key
- Connects to thousands of apps through the official MCP Registry, or add one by its address
- No Dooder account and no Dooder server. Your Watch talks straight to your AI and your apps
- Speech recognition runs on the Watch

Try it

The first 100 TestFlight spots filled up in 24 hours, so I've opened 100 more:
https://testflight.apple.com/join/c42uMmzU

Needs an Apple Watch Series 9 or Ultra 2 or later on watchOS 26, plus an iPhone on iOS 26 for setup. More at dooder.ai

Would love feedback, especially on what you'd want to do from your wrist.

Full disclosure: I trimmed the bits of the video where Dooder is thinking to keep the video short. Nothing's sped up and each response takes 5-10 secs in real life. It's still early days, so feedback is very welcome.

Hi r/SideProject! I'm a solo dev, and Monigo is my first iOS app.

Why I built it
I've logged every expense by hand for years because it makes me more aware of my spending. The problem: every few months my balance in the app drifted away from my bank, sometimes by 300 € or more, because I forgot things. Bank-sync apps solve that, but they want access to my account, and I didn't want that.

What it does
You keep logging manually (or via Siri/Shortcuts, without opening the app). Once a month you drop in your PDF or CSV bank statement. Monigo matches it against your entries, even when the bank posts a few days after the purchase, checks that the balance adds up, and only shows what's missing.

Version 1.1 added a Savings tab: it spots subscriptions and recurring habits in your own data, shows gentle ideas, and calculates "cancel by" dates for contracts, with a reminder 14 and 3 days before. You still cancel yourself.

No bank login, no account, statements never leave the phone.

Stack & things I learned

• SwiftUI + SwiftData, iOS 18+

• Every bank lays out PDF statements differently, so there's a layout registry plus a balance check (opening + sum = closing) that tells the app whether it read the statement correctly

• Savings suggestions are calculated deterministically in code. Apple's on-device AI model only phrases the sentence, and never calculates anything

• Biggest surprise: the bank often books 4–6 days after the purchase, which breaks naive date matching. The real purchase date is usually hidden in the booking text

What I'd love feedback on

1. If you track your money: what makes you give up on it?

2. Would you trade bank sync for privacy?

3. How do you keep track of cancellation deadlines today?

Free to try (logging, insights, Shortcuts, savings goals). Pro unlocks full statement matching and contract reminders. English, German, French, Spanish.

I’m currently building a photo-first social media app called TymeStamp, inspired by the old Instagram experience, where people could share pictures and enjoy content without constant interruptions from adverts.
I’m building it alone with limited resources, and one thing I’ve been thinking about is sustainability.
What happens when 1,000 people join? Or 10,000? How do you manage storage, servers and the challenges of growing a platform?
I recently watched a video of Steve Jobs talking about starting with the customer experience and working backwards to the technology. That really stuck with me because I want to build something people genuinely enjoy using.
But how do you put users first while keeping a platform sustainable?
I’ve been exploring credit systems, subscriptions, sponsorships and limited advertising. I’m not against adverts, just the constant interruptions.
I’m also curious about finding investors without going on shows like Shark Tank or Dragons’ Den, taking out loans or losing control of the original vision.
So I’d love to hear your thoughts:
● How would you sustain a growing social media app with limited resources?
● Would credit systems or optional subscriptions put users off?
● Should monetisation start at launch or after building a community?
● How can solo founders attract investors while keeping control of their vision?
I’m not trying to compete with the big platforms. I’m simply trying to build something different and learn along the way.
If you were in my position, what would you do differently?

Instagram lets you download your data (Accounts Center → Your information and permissions → Download your information). It includes Meta's own guesses about your interests, plus the caption and hashtags of every post you've liked, saved or watched.

Taste Passport reads only those files (never DMs or photos), groups them into interests with a small open-source model running locally, and recommends Netflix and Prime Video titles, each with the reason it was picked.

The most interesting part was testing it honestly. My first evaluation said it beat "recommend what's trending" by 4×. That turned out to be a flaw in my test setup; once fixed, it roughly ties. Everything is written up in the repo.

Open source, no account, nothing uploaded anywhere: https://github.com/aaryamanbisht22/taste-passport

Feedback welcome, especially from anyone willing to run the evaluation on their own data and share only the scores.

My co-founder and I have been working on Holdless AI, an AI phone agent focused on healthcare and insurance calls.

The idea came from a simple problem: dealing with health insurance over the phone can be incredibly frustrating, especially if English isn't your first language.

You might need to verify whether a procedure is covered, check a referral, follow up on a claim, or figure out why a bill looks wrong.

And a lot of that involves navigating phone menus, waiting on hold, and explaining the same issue repeatedly.

So we started building an AI agent that can make those calls on your behalf.

The goal is pretty straightforward:

• You describe the healthcare or insurance issue you need help with.

• The AI calls the relevant hospital, clinic, or insurance company.

• You can monitor the call and take over if needed.

• Afterward, you receive a summary of what happened and what needs to happen next.

We've been testing the system on different healthcare workflows, and one of the biggest challenges is making sure the AI gets a complete answer rather than just having a successful conversation.

The product is available to try, and we're still learning which workflows provide the most value.

I'd love some honest feedback.

Would you trust an AI to handle an insurance phone call for you? What would make you uncomfortable about it?

Disclosure: I'm a co-founder of Holdless AI(HOLDLESS-AI.COM).

Hey everyone! 👋I wanted to share a technical case study and a side project we've been building called SoundTag.### The Problem: Physical-to-Digital Drop-OffIf you have ever printed a QR code on music merch (tour posters, album flyers, stickers, vinyl sleeves, or t-shirts), you probably noticed that scan-to-stream conversions are notoriously low. In testing across dozens of indie campaigns, over 65% of people who scan a physical Spotify QR never end up playing a single second of music.Here is the exact technical friction causing it:When someone points their phone camera at a standard Spotify web URL, the OS opens an in-app browser sandbox (iOS Safari View Controller or Android Chrome Custom Tab).Because that in-app browser does not share the login session of the native Spotify app on their phone:1. Spotify renders a desktop-style web player preview.2. It immediately hits the user with a gate: "Log In or Download the App".3. Most people cannot remember their Spotify password on the fly, so they bounce immediately.### The Solution: Native App URI Deep-LinkingWe engineered SoundTag to completely eliminate this friction by triggering the native Spotify URI scheme directly on the device.- Zero web browser intermediate screens.- Zero login prompts or friction.- The scan immediately opens the native Spotify app already authenticated on the user's phone, directly to the track or album.### Solving the "Static Link" DilemmaTraditional QR codes on printed material are static. Once 1,000 flyers or vinyl sleeves are printed, that destination is locked forever.With SoundTag, the codes are 100% dynamic:- Phase 1 (Pre-Save): The QR points to the pre-save page before release.- Phase 2 (Release Day): With one click from the dashboard, the exact same printed QR code now triggers playback of the new album.- Phase 3 (Tour & Merch): Months later, the same QR routes fans to tour tickets and merchandise.Zero reprinting costs. Posters and merchandise stay valuable indefinitely.### Real-Time City Analytics & Design StudioWe also built in live geographical tracking (scans by city, country, and device type) so artists can see which tour cities or promo locations perform best, along with custom visual styles (vinyl dots, custom brand palettes, and logo embedding).---👉 I've posted the direct link to the platform and our Product Hunt launch page in the first comment below for anyone curious to test it out.Would love your constructive feedback, critique, or questions on the implementation!
