hi, made an app for people who want to actually stay consistent with their studies without being blasted by annoying ads and paywalls. as a student preparing for some major competitive exams, i spent months coding a 100% free and ad-free android app called penguin: study tracker. i was really frustrated with other tools on the market because everything useful was locked behind a subscription, so i decided to build exactly what i needed for my own journey. instead of just building a basic stopwatch, i wanted to gamify the core mechanics. the app lets you manage your curriculum, tracks how many seconds you spend on each individual question, and rewards consistency with 3d premium achievement cards to keep the motivation going. it has been live on the play store for a while now, but i'm looking to take it to the next level globally. since this community is amazing for honest feedback, i wanted to share it here. i would love to get your thoughts on the core features, the gamification system, or any ui/ux improvements you can suggest. how does the concept feel to you? play store link: https://play.google.com/store/ap... thanks a lot!
Built this guide after seeing the same AR problem repeatedly, teams manually chasing invoices while Zoho's automation layer sits mostly unused.
Covers three tiers: native reminders, workflow rules with conditional logic, and Zoho Books API integration for AI-generated follow-ups with human-in-the-loop approval on high-value invoices. Practical setup, not theory.
Worth a read if you're on Zoho One and still doing any of this manually.
I m building FastHook, a webhook gateway for developers who need to debug, replay, retry, and route webhook events.
The idea is simple: returning 200 OK does not always mean the event was safely processed. FastHook helps receive webhooks, inspect payloads, retry failed deliveries, replay events, and route them to multiple destinations.
Also I am a technical CEO - (Ask me anything about AI, LLM's SLM's, Server's architecture, Encryptions, Quantum Computers) Currently building the first AI doctor Avatar that can diagnose you from a video call.
App is finished ( pending review from playstores)..
Will launch it here at Product Hunt, where probably it will be seen only from Me, Myself and I
I built SecURL for low-noise external posture review of public sites. It reads what a browser, auditor, or researcher can already see, headers, TLS, cookies, redirects, and DNS/email posture, then turns that into clear findings and stakeholder-ready reports, without noisy recon. There is a free hosted scanner and an npm engine. Would love feedback from this community: https://securl.online
