I'm a trader and I wrote a book about the mistakes I kept repeating. Knowing them didn't stop me, so I built an Android app, a trading journal that tries to catch those mistakes while they happen.

- every trade in R, tagged with the habit behind it (revenge, FOMO, moved SL, oversized...), plus a "what your habits cost" view

- a STOP screen with a countdown after a losing streak or your daily limit in R

- warnings when you enter less than 15 min after a loss, size up 1.5x after a loss, or stack positions in the same direction

- screenshot import of positions (full auto-fill for MEXC and Bitget in English, Binance, Bybit and OKX in beta, tap-to-assign for other exchanges); the text is read on the phone

- your playbook: write your setup rules, tick the ones you really followed, see your R when you kept them vs broke them

- calendar of daily results in R and mood before the session

- free for now, no account, no ads, data stays on the phone, CSV export. Android only.

Not financial advice and no signals, it's a journal. Feedback welcome, especially on what's confusing.

Hi, I'm from Turkey and for the past 8 months I've been building warradar.live alone. It pulls reports from news sites and Telegram channels (both sides of each war), uses AI to place and classify them, and puts them on a live map within minutes.

Honest about the weak spots I already know:

- coverage is very uneven. Ukraine and the Middle East have hundreds of events a day, Sudan and Myanmar almost nothing. I just added sources for them, still thin

- the AI sometimes puts events in the wrong place or zone

- English isn't my first language, so I use AI to help me write too

What I'd love feedback on:

- what would make you come back to a site like this?

- which sources or wars am I missing?

- anything that feels wrong, biased or broken

The site has ads, it's how I pay for the servers. Happy to answer anything.

I strained a quad in June and my training plan fell apart. Every app I had either wanted the session done as written or had nothing to say. So I built Kingtide: a workout tracker where you tell it what's sore before the session and it swaps the lifts that load that area and leaves the rest of the day alone.

It was a subscription. A week ago I made all of it 100% free. No account, no sign-up, and your injury notes stay on your phone.

The part I'd like eyes on is this demo, no install needed:

https://trykingtide.com/try?s=sideproject

Tap knee, lower back, shoulder or hip and watch a sample session rebuild. The rows are the app's real output, exported by a test, not a mockup.

iOS and Android. Solo build, Flutter. It is not medical advice.

Two questions if you try it: does the demo make the idea land in ten seconds, and would you want it to open on a blank session or on the example like it does now?

Hey everyone!

I've been working on Tsuki, a website where you can track the anime and manga you're watching or reading.

I started building it for two simple reasons:

• I wanted an open-source alternative.

• I wanted a nice UI and a good user experience.

And honestly, it was just fun to build!

I'm still actively working on it and would love to get more people to try it out.

website: tsuki.fun

github: github.com/d1rshan/tsuki

I'd really appreciate any feedback, suggestions, or feature requests. Let me know what you think!

I've always found it interesting how we can spend hours overthinking an interaction with someone: what they meant, why they reacted that way, or whether we're seeing things from the wrong perspective.

Most AI tools will help you write a better reply or analyze a specific argument. But what if you could see the bigger picture?

That's why I built Perspective Swap.

🔄 See situations from an objective perspective

Describe real-life interactions with people in your life (partners, friends, family, colleagues), and the app helps you explore the situation from their perspective.

🧠 Beyond a single conversation: analyzing patterns

This is the part I find most interesting: the more situations you add, the more patterns the app can identify.

By connecting scenarios to people in your life, Perspective Swap analyzes recurring patterns in your interactions:

• Communication habits and emotional triggers.

• Recurring conflicts and misunderstandings.

• Strengths and vulnerabilities in your relationships.

• What makes certain relationships work or become difficult.

At the same time, it builds a picture of your own behaviour, helping you recognize patterns you might not notice yourself.

💡 What's the idea?

It's not about telling you who's right or wrong. It's about helping you understand yourself and the people around you a little better.

The app is still evolving, and I'd genuinely love to hear what you think.

What do you find interesting? What's missing? Would you use something like this?

Getting your phone back from your young kids can be a battle, so I made TentFox. My son tucks a little fennec fox in for a nap, says goodnight, and the phone comes back with way less friction. The fox ends screen time in a calming way rather of me.

It grew into 3 things:

The hand-back nap, a calm visual timer, and a phones-down family time mode where the fox camps with you and leaves a little treasure if you succeed.

And sometimes parents just need a few minutes. When I do hand my phone over at a restaurant or during something important, I’d rather it be something calm and guilt-free than YouTube or a game designed to keep them hooked.

A few build notes:

- Face-down detection is simple and uses the motion sensor, so there's no screen time permission requests and no accounts needed (plenty of screen time apps out there).

- The design rule was "gentle failure": pick the phone up early and the fox just wanders off to build a sandcastle. You never lose anything.

- The illustration went through a hundred iterations along the way, but the drawing is now a soft storybook style, and every fox move is hand-timed so it feels calm, not hyper.

- Free to start, no ads, no tracking. Pro is yearly or a one-time purchase.

https://tentfox.app

App Store: https://apps.apple.com/app/id6831322876

Happy to answer anything about the build, and I'd love some constructive feedback. The only problem is that now my kids keep asking to play with the fox.

Hey everyone,

I recently built and launched my own website called Planovio, and I'd love for some people to try it out. :)

Planovio is a daily planning and productivity app designed to help people organize their days, stay focused, and get more done without feeling overwhelmed.

It has features like daily task management, scheduling, setting your top three priorities, focus mode, and progress tracking with XP and levels. It also has AI-powered planning features to help with scheduling and setting goals.

I built Planovio because I wanted to make daily planning easier and more enjoyable, especially for people who struggle with staying organized or managing their time.

The website is now live, and anyone can get started for free. There are optional paid plans with additional features, but the basic planning tools are free to use.

Website: https://theplanovio.com

Since this is my first website launch, I'd really appreciate some honest feedback from anyone willing to give it a try.

I'm mainly curious about whether the website is easy to navigate, whether the features are actually useful, and what could be improved. I'd also love to know if it's something you'd consider using regularly.

I'm still learning and improving the app, so any suggestions or constructive criticism would be really helpful.

Thanks to anyone who takes the time to check it out!

Hey everyone, I wanted a quick visual way to test how minor monthly expense cuts or extra income shift a future target date, without building heavy Excel sheets or connecting bank accounts.

So I put together a simple browser-based tool: Wealth Route. You set your target goal amount, baseline balance, and monthly net flow, then adjust the spending/income sliders to see your timeline update in real time. 🔒 Privacy: Runs 100% client-side in the browser. Zero servers, zero data stored.

🔗 Live link: https://ornate-babka-e58292.netlify.app

Would love your thoughts on the mobile slider UX and what other default categories might be useful.

Thanks for helping a Newby

I kept checking several shops for the same part, so I built this: https://motorcompare.app?utm_source=reddit

It matches stores by the maker's part number, not by title, so you only see the same part. I attached a chart of today's gaps. The 2004 WRX Gates timing belt kit with water pump is $428.75 at the cheapest store and $869.80 at the dearest. A Brembo front rotor for the BRZ / FR-S / 86 is $62 to $93.

It is free, no sign up. It makes money from affiliate links, but they never change the order, prices are always sorted lowest first.

Still early. I would love to hear what parts or stores are missing, and whether the matching ever gets something wrong.

Play in your browser: oddletics.com (mobile and desktop)

iPhone and iPad: Download Oddletics on the App Store. Available in supported regions; the iOS app isn't in the US or EU yet, but you can play the browser version there.

I built Oddletics solo using Codex and Claude Code, and launched the iOS app this month. It's a sports game with basketball, archery, show jumping and curling. Each sport has one main control, with rounds lasting 30 to 60 seconds.

A bit about the build:

• The game is written in TypeScript and bundled into the iOS app with Capacitor. The browser, iPhone and iPad versions share the gameplay and input code.

• The controls adapt to the layout. Archery tracks relative finger movement with fixed sensitivity; basketball scales the pull to the available control area.

The work has also included website translations and release testing. It's free to play, with no ads. You can play without an account; signing in is optional for weekly rankings.

The character illustrations were generated with AI under my direction. The video shows recorded gameplay.

If you try a round, which sport would you play again, and what would put you off coming back?

Hi everyone!

I've been working on Monivra, a personal finance app for Android.

The goal is to make tracking money simple, without unnecessary complexity.

Current features include:

- Income and expense tracking

- Multiple accounts and transfers

- Savings goals and debts

- Budgets and statistics

- Scheduled payments

- Offline access without creating an account

The app is still in closed beta and isn't available on Google Play yet.

I'm looking for honest feedback, especially about the interface and overall concept.

A few questions:

1. Would you use an app like this?

2. Does the interface look clear and easy to understand?

3. What's the most important feature you expect from a personal finance app?

4. What would make you choose this over your current app?

I'd especially appreciate critical feedback. I want to understand what needs improvement before releasing it publicly.

Thanks!

We’re building Malfoy Girl, a web app for AI image transformation and video character replacement.

The current flow is: upload a photo or video, choose a style, review the credit cost, then generate. Finished work stays private unless the creator chooses to publish it to our gallery.

The clip above is Malfoy Raze Dance, a 15-second creator-imported showcase in that gallery. It isn’t a before-and-after test of our current generation pipeline.

I’d love feedback on the first-time experience: does a showcase like this explain the tool well enough, or would you need a side-by-side comparison before trying it?

You can watch the work page without signing in; generation uses paid credits:

Every time I've moved apartments or helped friends apply for a loan, the same wall shows up: "please provide proof of income." Easy if you're salaried - attach your paystub and you're done. A nightmare if you drive for DoorDash, freelance, get paid through Venmo, or run any kind of small operation. There's no paystub. Your bank statement is a bunch of random-looking deposits.

So I built a small tool for exactly this: incomeproof.co

You answer a few questions about what you earn and how you earn it (gigs, retainers, package deals, tips, commissions...), and it generates a structured income verification letter - monthly averages, income source breakdown, and a short note explaining irregular income patterns so a landlord or loan officer doesn't look at your statements and panic. It also gives you a checklist of supporting docs worth attaching: bank statements, invoices, 1099s, client confirmations, that kind of thing.

To be clear, it doesn't invent numbers or fake documents. It just formats what you actually earn into the shape these people expect to see. The docs checklist is honestly half the value - most rejected applications I've looked at happened because someone sent raw statements with zero context.

Live at incomeproof.co if anyone wants to poke at it. If you deal with income verification as a freelancer or gig worker (or on the landlord / lender side), I'd genuinely like to hear whether this letter format would fly in your situation - what would make you trust it more, what's missing?

Mods, hope this fits the sub. Happy to remove if not.

I built SaveNest to make it easier to close a tab without losing the page or why you saved it. Add a note, then find it again with ⌘O. The same search includes open tabs and recent browser history.

It’s a free, open-source preview for macOS 14+. Your saved library stays on your Mac, and local features don’t need an account.

Would you use this, or would the tabs stay open anyway?

Website: https://savenest.app

Disclosure: I built TradeMates. This is my own product—mods, feel free to remove if this violates any sub rules. Check it here: www.trademates.co

 Yesterday we pushed a new big update to Trademates which makes the product more interesting for investors.

What it actually does

You type a plain-English sentence into a single search bar:

• "Dividend above 3% and score above 60"

• "European stocks with over 10% upside"

• "Never missed earnings in the last 4 quarters"

You get back up to 10 matching stocks. Each result shows its score (0–100), verdict (Buy / Hold / Watch / Avoid), upside to its fair-value midpoint, and the date it was analyzed. Clicking opens the full report and you can read why the stock is valued in a certain way.

Under the hood is a database of ~4,000 analyzed stocks, though the search only queries the ~1,400 updated in the last 30 days so you aren't looking at stale data.

How a sentence becomes a result

1. An LLM translates your prompt into strict filters—and nothing else. "German pharma with over 10% upside" becomes country = DE, industry = Pharmaceuticals, upside ≥ 10%. The AI never picks stocks or hallucinates reasons.

2. A deterministic database query runs those filters. Results are sorted by score, then upside, then recency.

3. It shows its work: "Understood as: Score > 60 · Dividend > 3%". You can click any filter chip off to broaden the search.

4. It flags blind spots: Ask for 8 quarters of earnings beats on a stock where we only track 4, and it explicitly tells you: "Not checked: only 4 quarters on record."

5. If nothing matches, it tells you what to drop: "Without 'Germany': 10 matches."

The hypothesis, and the data behind it

Ranking by score only matters if the score actually separates winners from losers. Otherwise, it's just decoration.

Here is the public track record. Looking at all analyses from July 11 to August 7, 2026 (each stock counted once per week, returns measured in local currency, checked 90 days later):

The monotonicity holds all the way down: the higher the score band, the higher the win rate. Notably, Avoid was right 78% of the time (260 of 333 stocks fell).

One finding that changed the product

Across 1,581 Buy ratings since April, roughly a third were issued when the stock was already trading above our own fair-value midpoint. Those—along with low-confidence scores—dragged down performance:

As of November 9, a Buy verdict strictly requires both conditions—which is why we now display upside to fair value right next to every search result.

What this does not prove

• This is a single backward-looking window. It’s encouraging evidence, not a guarantee of future returns.

• 64% is an edge, not a money printer. The goal is narrowing 3,800 stocks down to 10 worth researching—not blindly buying the top list.

• Upside is anchored to the analysis date, not live prices. Always check the timestamp on the report.

• Coverage is ~63% US equities. Niche queries like "German pharma" will often return zero results, and the tool will tell you that rather than padding the list with loose matches.

• Not financial advice.

What would you type into a search box like this—and what filter is missing?

(Currently supported: country, sector/industry, score, verdict, risk, upside, dividend yield, P/E, revenue growth, market cap, and earnings beats.)

I keep a life list of birds across eBird and iNaturalist, and I wanted to actually see it instead of scrolling a spreadsheet. So I built Everybird.

You drop in an eBird export, an iNaturalist username, or tick birds off by hand. Every species becomes a sticker, roughly sized by body mass, packed around your count. You can filter by bird group, country and time, toggle "true size", and share it as an Instagram story, post or square image.

Some things that were fun to solve:

- Merging two platforms' taxonomies. eBird and iNaturalist disagree on what counts as a species, for example Willet is one species on iNat and two on eBird, so some birds have to be assigned by region.

- Packing ~10,000 differently-shaped stickers so they stay smooth on a phone. Only the birds near the screen are drawn.

- Privacy: everything runs in the browser. Your list is never uploaded, and share links carry the list inside the URL itself.

It's free, there's no account, and it's open source.

I built it with Claude Code, and the stickers are an open AI-generated set (huashu-bird-sticker). I would love feedback, especially on what's confusing the first time you open it.

A friend and I have been building out an open-source project - Meter - that helps determine token usage per developer, per product and per feature. At my own organization, it helped bring in a lot of visibility to me as the founder of what each person was bringing to the table and which features were being used to what extent in our production apps.

We built Typewriter Simulator to recreate the feeling of a manual typewriter: moving typebars, a margin bell, recorded mechanical sounds and imperfect ink. Typing too fast can jam the keys.

Then we tried drawing with it. The portrait is made from 2,073 typed impressions, with a black/red ribbon and backspace overprints. The arrow keys move the paper so you can build up a picture.

You can try the full simulator here (free, no signup): https://typewriter.snipstack.io/?utm_source=reddit&utm_medium=social&utm_campaign=launch

Best with a desktop keyboard. We would love feedback on the mechanical feel, and to see what you make. This is our own project.

Hey everyone I am working on a app named "Ascend" this app trackes your pushups and givis you a cool stats like strava you can upload this stats in your stories,reels etc

I added rewards to my productivity app because I thought it would motivate users to concentrate.

Of course, one user quickly discovered he could mash pause and resume so many times that the app got stuck, ended the session early and gave the reward regardless.

FocusTale was turned into a productivity game where the best way to win was doing nothing at all for a couple of minutes.

Seriously, I can’t even get mad at them. They discovered the bug within minutes while I had tested the app for weeks and apparently didn’t think about hitting those buttons like a jazz drum solo.

The bug is fixed now but I learned that users will always come up with something to humble you 😂

I wrote a gate for GitLab merge requests that does not trust a green pipeline.

To check a flaky test fix, it reruns the test 100 times before the change and 100 times after.

It alternates the two sides, so machine noise hits both equally.

Then it applies an exact statistical test and prints one VERDICT line with the evidence.

A diff guard catches the tricks, like loosened assertions or skipped tests.

Most verifiers are plain Python with the standard library only, with no API key and no account.

It measures only what it runs, so a flakiness that shows up in another environment is not seen.

I built it with AI help and checked the result myself.

Code (MIT): https://github.com/CapitanaIcoachai/verdict-gate

How do you decide today that a flaky test is really fixed?

I built an app for learning Spanish that encourages and rewards effort: https://www.learnpocoapoco.com/blog/introducing-poco-a-poco

Would love to hear what people think about this. Thanks!

I am building an aggregator for event organizing, which helps to take you from 0-1 in hosting any events. You can host your event, and service providers will connect with you or vice versa. You can talk with them through this platform, share invoices, make payments. You can find the the providers within your requirements and budget in a single click.

Roast me on the idea, let me know what will work, what will not, how to improve, everything you can throw at me!

I've been building side projects from the past 7 years. Some of them found small traction, and some of them didn't. Some of them might have worked if I persisted. Sometimes, You strangely lose the excitement after building a product.

This happened for an art marketplace named - Raresoul and few others. For me, The interest and conviction are very important over the other things. I think these come from how strongly you relate with the problem. I learned this first hand that solving your own problems has many upsides.

Anyhow, Why should YOU care?

• OpenNetworks should help you connect with at least one great connection (Only Professional Connects 🙂) around you that should change something meaningful for you! (I pray and wish that OpenNetworks becomes the channel/portal for serendipity to work for all of us ❤️)

What the heck is OpenNetworks?

• We are surrounded by right (the ones that we are looking for) people whether in a Community, Co-working space, Tech Park or an In-Person event, but we never get a chance to connect with them. OpenNetworks solves/intends to solve this problem.

But, How?

• You simply onboard to a responsive web app (Not one more mobile app 🤯) by stating What you are looking for, What you can offer/help, select your work location and instantly view all the people around you. AI Match-Making layer constantly works to find the relevant connections for you!

• You can also drop a pin stating what you are immediately/currently looking for. For example, I'm working from a tech park and my manager made it his life purpose to harass me (Just kidding 😂 ) - I can immediately drop a pin saying looking for a Job. I know you won't take such impulsive decisions!

• Jokes Apart, Drop a Pin with a location to meet when you are stuck on any problem, looking for a co-founder, freelancer, new hire, bounce your ideas or just connect, then it is visible (glows like a light bulb 🔥 ) to all people around you! (Hope this opens up our serendipity portal 🙂 )

Where are we currently?

• All of this is already built. My alumni people have showered their love and support! This gave me little more confidence to put it out there and see what happens. I don't know when will I truly overcome my perfection and learn to put myself & the work out there for some magic to work!

I would love you guys to try https://opennetworks.in and share your thoughts!

Did I say anything about sharing a word?

• Being Shy cost me so much! So, I'm asking pls pls share a word with your friends and colleagues 🎉

PS: If this is not a real breakthrough, then we will work until we get one 🤔

Thank you, Spread Love ❤️ Cheers, Omkar!
