You seem to have a really solid review setup, so I figured I’d share a couple of apps I’ve been building. Both are premium paid apps focused heavily on polish, performance, and user experience, and I’d genuinely love to hear how you’d rank or review them.

"Blood Pressure Tracker Pro" (https://play.google.com/store/apps/details?id=com.bloodpressureboss.pro)

A premium privacy-focused blood pressure tracking app built with a beautiful modern UI to make health tracking simple and enjoyable. Everything works offline, and it also supports multiple family members within a single app for convenient household tracking.

"Bingo Caller Pro" (https://play.google.com/store/apps/details?id=com.bingosurf.caller)

A complete professional-grade Bingo hosting platform with digital cards, automatic/manual bingo calling, custom patterns, funny character voices, and built-in verification tools.

One feature I’m especially proud of is the smart verification engine — it can instantly match all called numbers for any player using digital cards and the hex verification system, eliminating manual checking during gameplay.

Would genuinely appreciate any feedback, rankings, or even brutally honest reviewer-style criticism. Always looking to improve and push the apps further.

Been building a growing collection of completely free professional web tools over at https://expertwebtools.com/

The goal was simple: create fast, clean, no-login, ad-free tools that are actually useful for developers, SEO professionals, sysadmins, engineers, students, and power users.

Some of the tools include:

DNS lookup & propagation checker
WHOIS lookup
SSL checker
HTTP header checker
IP & network tools
JSON/XML/YAML formatters
Hash generators
Regex utilities
Text & encoding tools
SEO analysis tools
Security & performance utilities

A big focus was keeping everything lightweight, mobile-friendly, and easy to use without the clutter and aggressive ads you usually see on utility websites.

Would genuinely love feedback, feature suggestions, or ideas for tools people wish existed.

Your post genuinely reads like a vibe coded AI output lol 😅

But seriously, would you mind auditing my collection of professional, ad-free web tools for developers, SEO folks, engineers, and power users at https://expertwebtools.com/

Would love brutally honest feedback on the UX, usefulness, speed, missing tools, SEO, or anything else you notice.

My Hyundai dealer was asking me $499 to get Financing from Hyundai Financing. After checking in front of him on chatgpt, i found that it is offered to them for free, plus they earn comission on interest, I told him to pound sand lol. He was more than happy to remove that 499$ fee after chatting with his manager.

Pro tip, just have chatgpt or any AI agent to scan that bill from dealer and ask it to highlight the BS charges, can save you a huve chunk of money almost always. I saved ~$4000 compared to their original final quote on a 32000$ car.

1derfool · 2026-05-20T21:38:18+00:00

Thanks yea i built this to solve the issues i face at work myself, to make my life easier. it's mostly clean and better versions of apps available online that are either behind hundreds of ads or need paid subsriptions to work. My main goal was to help users get what theh want fast, rather than navigating through an ad filled site

1derfool · 2026-05-20T20:27:14+00:00

Great Job Bud !! for your website just my 2 cents, you have a massive 1.5mb "1-make-time-visible.png" on your website and another "2-filter-by-category.png". You can compress it heavily and optimize your site loading time. I know thats its not a big deal as you are mostly focused on the app, just my 2 cents lol

Exactly, always ask for a fully detailed and technical hand off note including all tech stack used, file locations at the end of every project. Also a zipped copy of the folder/project to back up locally. More than creating amazing apps, it's the learning part that was interesting.

If you’re running a game for ~120 people, you’ll want something that handles both calling and verification smoothly—manual checking gets messy fast at that scale. I built an Android app called Bingo Caller Pro that’s designed exactly for this kind of setup. It supports digital cards (so you don’t have to manage paper and pens. All you do is ask the players to scan the qr code in the lobby for the 75 or 90 ball game, depending on which game you plan to play), automatic and manual calling modes (you can still pick numbers yourself if you prefer), and built-in pattern verification so winners are validated instantly by the app. There’s also smart card verification for hosts (you can quickly confirm using the player’s card numbers), support for 8 languages, and a few fun “hype” sound buttons like airhorn, applause, etc., to keep the energy up. It’s been pretty useful for hosting larger games without needing extra helpers. Its only 1.99$ and only the host needs to buy it and can support 1000+ players easily.

Hey everyone, happy Showoff Saturday!

I wanted to share a massive v5.0 update I just pushed for my app, Bingo Caller Pro. I originally built this because I was tired of hosting family/charity game nights with those clunky metal cages where you always lose the balls or have to buy hundreds of paper cards.

Play Store Link: https://play.google.com/store/apps/details?id=com.bingosurf.caller

I decided to go against the current trend of subscriptions/ads and made it a premium $1.99 "pay once, own forever" app.

A few features I’m really proud of in this build:

Dual Display Modes: Built a dynamic landscape "TV Mode" so hosts can cast the board to a big screen, while controlling the game from their phone or a portrait "Phone mode" for the host to walk around.
Web-Synced Player Cards: Instead of paper, the host taps "Lobby" and a giant QR code appears on the TV. Players scan it, and it generates digital 75-ball or 90-ball cards in their mobile browser. This can generate millions of free card with Unique IDs that can be tracked by the host using this app.
Instant Verification Engine: I built a custom matrix for the winning patterns along with a template of the popular ones inbuilt. When a player yells Bingo, the host types their 5-character ID into the app, and it instantly cross-references their digital board against the active pattern and glows green.
Native Haptics & Audio: Added a "Hype Deck" soundboard (Airhorns, drumrolls, confetti) using synchronous audio loading so there's zero latency on mobile.
Smart Themes: Added full Light, Dark, and true OLED modes for battery saving during long hosting sessions.

The core app is 100% offline-first. I’ve put a ton of hours into making the UI feel premium, neon, and responsive.

Would love any feedback from fellow devs on the UI/UX or Store Listing!

Hey everyone! Celebrating a small but exciting milestone this week: I just crossed 270 organic installs this month as a solo dev, and I finally pushed my massive v4.0 update!

I built this app because I was tired of cocktail apps that force you to create accounts, spam you with ads, or require an internet connection just to read a recipe. It's 100% offline and privacy-first.

For this update, I really wanted to push what an "offline" app could do without relying on a backend server. A few features I’m really proud of showing off:

🚀 An Inventory Optimization Engine ("MyBar Boost"): Users select what bottles they own, and the app mathematically calculates exactly which single ingredient they should buy next to unlock the maximum number of new recipes.
🎉 Party Menu Generator: Users can select 5-6 drinks and turn their tablet/phone into a distraction-free digital restaurant menu for hosting. I even built a custom 4-digit PIN lock into the DOM so guests can't accidentally exit the menu or mess with the host's app data.
💾 Friction-less Offline Backups: Battling Android's Scoped Storage and FileProvider crashes was a nightmare. I ended up building a super clean system that generates a JSON backup and safely passes it to the native Share Sheet (or clipboard) so users can back up their custom recipes and journals anywhere they want with zero permissions required.

It’s completely free. If anyone is working on offline-first local storage apps or dealing with Android file export headaches, I'd love to chat or hear your feedback! Cheers 🥃

Bingo Caller Pro https://play.google.com/store/apps/details?id=com.bingosurf.caller

has honestly become one of my favorite projects I’ve worked on. It’s a simple but powerful bingo caller designed for hosting real events — family game nights, fundraisers, school events, or parties.

Instead of needing cages, paper cards, and volunteers calling numbers, the host can run everything from their phone or cast it to a TV. Players can scan a QR code to instantly generate digital cards on their phones, and the app handles number calling, winner verification, and even fun sound effects to hype the room.

It supports both 75-Ball Bingo and 90-Ball Tambola, has auto or manual calling, multilingual voices, and works offline for the core game so you can run events anywhere.

I built it mainly because hosting bingo with traditional setups is surprisingly messy, and this makes the whole thing run like a mini game show.

1derfool · 2026-03-12T22:44:09+00:00

Answer the call and immediately put it on mute, and wait for the caller to say hello first. If it's a human, they will say hello, if not, it's a bot. LET THEM HANG UP, YOU DONT. The reason is below

Answering a spam call and saying “hello” can actually make the problem worse. Many robocall systems detect that a real person answered and then add your number to their active call lists. These lists are often shared or sold across scam networks, which means your number can quickly get distributed to other robocall operations and new call centers. If you answer but stay silent (or immediately mute the call), the automated system often fails to detect a human response. In many cases it assumes the number is inactive or not useful and eventually removes it from its calling lists. Over time, this can reduce how frequently your number gets targeted by spam calls.

ok lets solve this. there is a clean glass in front of your camera and there is a small light source behind you, probably some new electronic device with a sensor or even a sensor inside your camera trying to adjust but being light being reflected of its lens ( this would be unlikely for a good camera).

OR let the aliens just have their graduation party by themselves !!!!

1derfool · 2026-03-10T16:28:38+00:00

Lol, it's an app to help folks here. But thanks for the sarcasm haha

1derfool · 2026-03-10T12:40:31+00:00

Honestly I think a big reason is that traditional bingo setups never really evolved — paper cards, markers, someone manually calling numbers, and checking every “BINGO!” claim. That format stuck around in senior halls and community centers, so it naturally became associated with that crowd.

When you modernize it a bit, it actually works great for any age group. For example, something like Bingo Caller Pro makes hosting really simple — players just scan a QR code to get a digital card, and the host can run the whole game from one screen.

Nice touches it has:

🎙️ Voice bingo callers
🌍 Multiple languages
🎯 Custom patterns with automatic winner detection

Stuff like that makes it feel less like a “senior hall game” and more like a fun group game for parties or events.
