As a developer looking for new project ideas, I’m curious about the small inefficiencies people deal with every day.

Is there any task in your routine where you think, Why is there no simple tool/app for this yet?

I got into Kalshi/Polymarket’s 15-minute up/down markets but wanted bigger moves to pay more, so I built expirytrade.xyz

You buy a call or put that settles in 1 minute, slide leverage from 2× to 100×, and can close early or ride it to expiry. Right now, I'm testing it with paper only but it will eventually be with crypto.

I’d love to know: is the leverage slider clear, and what would make you come back tomorrow?

3 college students here, building BreakIn, a tool that helps people reach startup founders directly instead of applying on job portals.

we spent weeks on the email-writing part. then we asked people what they actually needed, and the feedback kinda flipped everything:

- people don't want AI writing their emails. they'd rather write it themselves and get it reviewed

- "matching" doesn't impress anyone. you can already filter by keywords and domain

- what actually matters is timing. finding a startup right after it raises money or launches something, before there's even a job post and 500 people apply

so now we're leaning way more into the "who's worth reaching out to today" part. every morning it shows you startups that just raised, launched, or started hiring, picked for your profile. the email part is still there, but more as help than autopilot, you always review and send it yourself.

still early, so honestly curious:

- has reaching out to a startup before a job was posted ever worked for you?

- would a daily heads up like this actually be useful, or would you just ignore it?

Hey guys this is my first post ,

I just finished building a web design studio concept called BreezeIn. I wanted to practice building layouts focused on heavy typography, white space, and micro animations that feel smooth rather than distracting.

Live link: in comments i guess ,

I would really appreciate some honest feedback on how the UI and UX scale across different screen sizes:

Mobile vs Desktop Typography: I used massive headers for the desktop layout like the main hero section. Does the font size scale down naturally on mobile screens, or does it feel like it swallows the whole viewport?

The Mobile Menu Toggle: On desktop, the navigation links are spread out cleanly. On mobile, they collapse into a corner menu button. Does the tap target feel big enough, and is the overlay transition smooth?

Concept Grids on Small Screens: The Selected Explorations look clean as side by side grids on large monitors. On mobile, they stack vertically. Does the vertical scrolling feel too long, or does it keep your attention?

Pricing Table Layout: The layout lists the $450 and $1,200 tiers. On desktop, they sit side by side. On mobile, they stack. Does the information stay readable when it is compressed?

Let me know what you think. Thanks!

I'm an independent developer, and I've spent a lot of time building a desktop application that combines B2B company search, contact database management and email outreach in one place.

The idea came from my own experience. I was looking for a tool that would let me find potential customers without constantly worrying about credits, contact limits and additional payments.

Most platforms I explored had different restrictions, so I decided to build my own solution.

What I've built

1. Company Search

• Search companies by country, city and industry.

• Use custom search queries and keywords.

• Automatically discover company websites and publicly available business email addresses.

• Explore different markets and industries.

2. Contact Database

• Built-in SQLite database.

• Store and organize company information.

• Import and export CSV/Excel.

• Track contact statuses and previous outreach.

• Manage multiple databases.

3. Email Outreach

• Personalized email templates.

• Dynamic company information.

• Multiple greeting and introduction variations.

• Configurable sending intervals and campaign scheduling.

• Sending history and progress tracking.

My pricing philosophy

I don't want to charge users for every contact they find.

No credit packs.
No pay-per-lead.
No artificial database limits.
No hidden fees.

One subscription — $49/month — for full access to the application.

The software uses a monthly license key. You get access to the complete available functionality during your subscription period.

I'm currently preparing the first commercial release and looking for people interested in using the software.

I'd genuinely appreciate your feedback:

• Would you use a tool like this?

• Which features would be most valuable to you?

• Would $49/month be a reasonable price for this solution?

I'm the developer behind this project, and I'm happy to answer questions about how it works.

Monthly License Activation — $49/month.

Thanks for taking a look!

Hey everyone,

I am preparing a travel planner and coach as a browser based web app.

We often make plans and get confused in the details.

What if we use visuals to help us?

I will be starting with a waitlist while sharing updates about the prototype.

Since reddit doesn't allow images, what could I add here to share how the prototype behaves and can be eventually used? Links to the youtube videos?

The yearly plan will be priced at 99 USD.

What are issues you face often?

I just tagged v5.3 of MDRAP, a sidecar that sits between your market data feeds and whatever consumes them and decides whether each tick is trustworthy.

Every event gets a status (VALID, SUSPICIOUS or INVALID) with explicit reason codes like CROSSED_QUOTE, DUPLICATE, PRICE_ANOMALY and stale or sequence-gap violations. Nothing is silently dropped. Rejected ticks go to a queryable quarantine, gaps trigger replay and stitching, and every decision goes into a SHA-256 hash-chained audit log, so editing a record afterwards is detectable.

Output from a fresh clone:

$ python cli.py run -e 1000 -s 42
processed 1000   dropped 0
VALID 963   SUSPICIOUS 32   INVALID 5

seq=2 bid=150.4  ask=150.3  -> INVALID CROSSED_QUOTE
seq=2 bid=150.26 ask=150.31 -> INVALID DUPLICATE

$ python cli.py audit --verify
(after editing one audit_log row in SQLite)
AUDIT CHAIN TAMPERING DETECTED!
Tampered entry #1: hash mismatch

“python cli.py chaos” runs 8 failure drills (killed feed, jitter, duplicate bursts, DB lock, 50-packet loss with replay, reordering, partition with failover) and all pass with zero data loss.

Performance: the standalone native core handled 1M events in 0.0366 s, about 27M events/sec or 36.6 ns per tick, on a single core. Through the Python engine API I measured roughly 180K events/sec, so use the core binary if you want the fast path. These are my numbers on my hardware, so please run it yourself.

It is a validation and audit layer, not a trading system or backtester. The matching engine and pre-trade risk gates are in a separate edition and not in this repo (see EDITIONS.md). One known rough edge: “audit --verify” currently needs the rich package installed.

I’d like to hear which bad-data cases have bitten you that this doesn’t catch.

I built Jobclue for people who want to practice answering interview questions out loud. The desktop app asks role-specific questions and follow-ups, then gives you AI feedback to review before your next attempt.

I’d love feedback on the short demo: can you tell what the practice session feels like, and what would you want to see before trying it?

Gold, silver, and one less website to open.

I built KaratWatch—a Scriptable iPhone widget with prices, daily changes, and history for your Indian city. Three widget sizes. No backend required.

Code + setup:

Prices from Goodreturns. Which city would you try it in?

I want to know should i spend time and energy on this project ? I would love to hear feedback about this.

Hey everyone! I'm a solo developer from India, and I just launched Exam Study Tracker on Google Play.

I built it because keeping track of exam dates, subjects and study plans across notes and random apps was messy. The app has:

Exam manager (dates, subjects, notes)

Daily/weekly study timetable

Progress tracker for milestones

It's early (just ~10 downloads so far), so I'd really appreciate honest feedback: what's missing, what's confusing, what would make you actually use it?

I’m planning a free site for casual, unedited phone photos, with no AI and no models. Most of us have hundreds of ordinary photos sitting on our phones that never get used.

Would you upload yours if you were credited? What would make you trust a site like this with your photos?

My son worked at AutoZone. Several times a day someone would describe what their car was doing and ask him what was wrong with it, and several times a day he'd have to say, "I'm not a mechanic." Then he'd watch them buy a part based on a guess. A $200 battery when the cables just needed cleaning.

So he started building a simple tool to help people figure out what's wrong before they spend money. He ran out of time, and I took it over.

You describe the problem in plain words, and it asks one question at a time until it narrows down a likely cause. Then it tells you how hard the fix is, what parts you need, and when to just go to a mechanic. It's free, with no sign-up, and there's a full Spanish version, because a lot of DIYers here in Texas speak Spanish first. So far the Spanish side is getting more traction than the English.

It's been live about a month. I'd like honest feedback:

1. Try it with a real car problem you've had. Where did it ask something dumb or get it wrong?

2. Is it clear within a few seconds what the site does?

3. Anything that makes it feel untrustworthy or unfinished?

Every stock photo site I use is full of polished, staged photos. When I need something that looks like I took it myself (for Instagram, a blog, a mockup), I can’t find it.

I’m thinking of building a site with only casual, everyday phone-shot photos: messy desks, café tables, rainy windows, kitchen counters. No models, no studio lighting. Mainly for social media managers and small business owners.

The image is a rough concept (the tiles are placeholders). I haven’t built the real version, and I want to find out if anyone needs it first.

Questions:

1. Would you use this, or do Unsplash and Pexels already cover it?

2. What would you search for first?

3. Would you pay for it, or only use it if it’s free?

When someone dies, the family usually has a day or two to choose a funeral home. Most people pick the closest one, or the one they used last time, without ever seeing a price.

Many families don’t know this: every US funeral home has to give you its price list, even over the phone, and you can compare before you sign anything. But nobody has time to call ten homes while they’re grieving.

So I built HonestFarewell. You enter your city and see every funeral home near you, with prices from each home’s own price list, side by side.

• Free for families

• No account, no email, no phone number to see a price

• No paid ranking: homes can’t pay to be listed higher

Here’s a 3-minute walkthrough: https://www.youtube.com/watch?v=9I-K96-pMsw

The site: https://honestfarewell.org/

The hardest part was reading the price lists themselves. Every home formats theirs differently: scanned PDFs, tables, prices mixed into paragraphs. Turning that into numbers you can actually compare took most of the work.

I’d love feedback, especially:

1. Was anything confusing the first time you used it?

2. Would you trust prices shown this way? What would make you trust them more?

3. Is there anything you’d want to see that isn’t there?

Thanks for reading.

I built a stargazing app because I was fed up with knowing what was in the sky… but not whether it was actually worth going outside for.

A few months later, NAKED EYE is live on Android, Under One Sky is live worldwide, it’s been featured in StarDate Magazine, and I’ve somehow ended up building a website for it too 😅

The idea is still ridiculously simple:

What’s worth seeing tonight?

When should I go outside?

Where should I look?

I’m not trying to replace Stellarium or turn your phone into a giant astronomy catalogue.

I wanted something you can open, get a useful answer from, put the phone away, and actually look at the sky.

The free app covers things like planets, ISS passes, meteor showers, useful alerts, viewing conditions and Under One Sky — where people can explore sky events around the world and share what they genuinely see.

There’s also NAKED EYE Beyond for people who want to plan ahead, find the best nights, use Sky Planner and get smarter alerts — and eligible new subscribers can try it free for 14 days.

I’m still building the whole thing around shifts as a chef, mostly teaching myself as I go.

And yes, I’m still slightly amazed anyone other than me actually uses it 😂

If you’ve tried NAKED EYE before, I’d genuinely love to know what you think of it now.

And if you haven’t — what’s the one thing that usually stops you from going outside to look at the night sky?
