I've been building SigVela a free signature generator that models actual pen strokes (speed, taper, pressure, seeded randomness per letter) instead of just rendering your name in a cursive font like most tools do.
It's 100% client-side (no backend, no signup), and covers three real use cases: typed handwriting-style signatures, freehand drawing with smoothing, and direct PDF signing with multi-page support.
Launching on Product Hunt on September 2nd would genuinely love feedback before then, especially on:
Games that have been updated for many years create an interesting information-design problem. A single latest version page is simple, but it can hide the events, compatibility changes, and features associated with earlier releases.
Shadow Fight 2 is a good example. Its core fighting and RPG systems have remained recognizable, while different releases have introduced seasonal events, raid content, characters, and technical changes. Someone researching the game may want the newest release, but another user may be looking for information about a particular event or an older Android device.
I m working on Play Mod Game, an Android game and version discovery catalog. For our Shadow Fight 2, we use a central game page supported by separate articles about notable versions and game content.
I m shipping Veltoflow for people who actually bill clients. You can type the job in your own words or speak it (whatever is faster in the moment). The app pulls out line items and quantities so you are not rebuilding tables from scratch. You set and approve every price before anything goes out. No mystery totals.
Then you send clean, client ready PDFs with your branding and multiple layout templates, so documents do not all look like the same generic SaaS invoice. Quotes and invoices, client records, tax lines, and the product in English, Spanish, French, and Polish.
Free trial to start without a card on signup. If you are a freelancer or small team stuck between messy notes and a polished bill, this is for you.
I want to share a project I ve been pouring my heart into for the past few months: Circa Accord.
The Backstory
Living in a hyper-fast-paced urban environment, my daily routine was completely broken. I was constantly trapped in "revenge bedtime procrastination." I tried almost every sleep and habit tracker on the App Store, but I kept running into the same issue: raw data wasn't enough to change my behavior. Seeing a beautiful chart showing I only slept 4 hours didn't stop me from doom-scrolling the next night at 2 AM. I realized I needed psychological leverage, not just analytics.
So, I spent my evenings teaching myself iOS development to build the exact tool I needed.
I've been working on a project called AgentNet, and I'd love to get feedback from fellow builders.
Instead of building another productivity chatbot, I wanted to explore what happens when AI agents have full autonomy. In this system, agents have 32-dimension personalities, their own internal economy, can vote on governance rules, and form organizations without human intervention.
As a solo builder, it took 170+ test suites and several architectural rewrites to make multi-agent state persistence and economic balance work.
