Chibe
APK
In the past, many homes had a chiming or cuckoo's clock, that would make a noise every hour/half hour/quarter hour, Chibe emulates this behaviour in your phone. Instead of making a noise, Chibe vibrates your phone, so that you are reminded of the time, but you don't annoy the people around you. This can be useful during activities, where you want to be reminded of the time, without looking, like sporting or reading, or when you just want to keep better track of your time. Features: * Choose at what interval you would like your phone to vibrate * Choose between multiple vibration patterns, so you won't confuse Chibe with normal notifications. * Create your own vibration patterns * Configure times at which Chibe should be silent, so you won't be annoyed at night. Permissions: * Control vibration: Chibe uses this permission to make your phone vibrate at set intervals. * Run at startup: Chibe uses this, so the you don't need to reenable it every time your phone reboots.

Child Resus Calc
APK
This App provides fast calculation of endotracheal tube size, defibrillation energy and drug doses for Paediatric Resuscitation and Rapid Sequence Intubation (RSI) in a pre-hospital paediatric emergency situation. THIS APP IS INTENDED TO BE USED BY SELF-EMPLOYED DOCTORS/PHYSICIANS. THIS APP IS AN INFORMATION TOOL ONLY AND NOT A SUBSTITUTE FOR PROFESSIONAL JUDGEMENT. Always enter the child’s weight if possible. Guessing the weight by New APLS Formula is just an approximation. The actual weight may differ markedly. I did not (yet) implement such a thing as a maximum weight nor a maximum dose. E.g. if you enter a weight of 500 kgs the App will calculate 2000 Joules defibrillation energy, 5 mg Adrenaline, and so on.

APK
A traditional strategy game to be played on a tablet. Play with up to 6 players, or against the machine. The objective is to be first to race one's pieces across the gameboard.

ChineseTtsTflite
APK
A TTS engine developed with Kotlin + JetPack Compose + Tensorflow Lite, which works totally offline. There are two models available: FastSpeech and Tacotron, both of which are from TensorflowTTS. Because the voice is generated in real-time, it has high performance requirements. The FastSpeech model works fast but the generated voice has poor anthropomorphic effect. It works well on a middle-end device. The Tacotron has high performance requirements. Though the overall effect is better, the speed is very slow. Therefore it's bundled only for test and can't be used in practice.

Ching Machine
APK
Automatic "ching" for practicing Thai music. * Sampled ching and glong sounds from real instruments. * Tempo selection. * Start playing with "chup chup" (the initial double-strike of the ching cymbals.) * Create your own drum patterns. I hope you enjoy this program! Please note that while this app contains both Thai and English translations and instructions for the most complicated functions, the majority of the user interface has been deliberately kept in Thai with the aim of encouraging interest in Thai script and the Thai language, as well as Thai music. I hope that the app also invites you, then, to be curious, push buttons, learn and explore, and have fun!

Chip Defense
APK
Chip Defense is a casual game for Android devices of the tower defense genre. It centres around a design of electric circuits and logical chips, evoking the good ol' days of 8 bit micro-processors. The attackers in this game are represented as bits and bytes. To defend the cpu against them, the player builds chips in designated slots. These "towers" deal damage by operations such as subtraction, right shift, bitwise and, etc. As usual in these games, the chips can be upgraded in strength. The game features "heroes of the information age": persons that had great influence on the development of modern computers. They come with a short biography und provide global bonuses that make the game considerably easier. Currently, there are more than 25 heroes and heroines. The game comes with 32 predefined levels, but it has also an "endless" mode with randomly generated levels. Supported languages are English, French, and German. Supported operating system versions: From version 1.58 onwards, Android 6 or later is required. Devices running Android 5 (i.e. more than 10 years old) should use version 1.57.

Chitralaya CloudGallery App
APK
Never Lose a Precious Memory Again! 📸✨ Chitralaya CloudGallery (चित्रालय - "House of Images" in Sanskrit) is your personal photo fortress that transforms Telegram into unlimited, truly private cloud storage! Say goodbye to the anxiety of losing precious memories and hello to unlimited backup freedom. 🌟 What is CloudGallery? Chitralaya CloudGallery is a simple open-source Android app that turns your Telegram account into a private photo cloud storage — no signup, no servers, no tracking. Your photos go straight from your phone to your own Telegram chat, giving you free, practically unlimited backup space with full control over your data. It’s not a company or a service — just a open-source tool made by a privacy-minded developer who believes your memories should stay yours. 👋 Hey there! I’m Aditya, the guy behind AKS-Labs. Before you scroll, let me make one thing clear — I’m just another user like you, tired of the usual “cloud storage deal” — free at first, then you pay with your money... or even worse, with your privacy. So I built something different — Chitralaya CloudGallery. It’s not a company, not a service. Just a simple, open-source tool — a bridge between your Android phone 📱 and your Telegram account 📡. 🤔 Why even build this? I was using Google Photos like everyone else. Free storage, nice features, AI magic… but then I realized: Google scans my photos to “offer me memories” → which also means they read them. Google uses user data to personalize services, show relevant ads, improve products,services. We users don’t even know or read what other privacy-concerning terms we’ve agreed to at the time of sign-up. And will they only use data collected from Google Photos to improve Google Photos — or does it include all Google products? Sharing a link doesn’t mean it’s private — anyone with that link can see your photos. Needs to compress images when free storage is full. One day, “free storage is full” and they said: “Pay up for more storage.” Google, builds entire business models around data. That’s when it hit me: my photos aren’t mine. I wanted something unlimited, private, and mine. And then I looked at Telegram. But wait… Why Telegram📡? Can’t Telegram see my photos? This is the elephant in the room 🐘. “Aditya, you’re asking me to upload my private photos to Telegram. Should I trust them?” Here’s my honest take: Telegram encrypts your data in transit, but not end-to-end (like Signal). So if they really wanted to, they could peek. But let’s be honest — so can Google, iCloud, OneDrive, or any cloud you don’t run yourself. The only way to have absolute control? Run your own server. But not everyone can afford or maintain that. But here’s the thing: Telegram gives insane free cloud storage. No limits (beyond what you can practically upload). No compression if you upload as files. And their infra is stable enough to trust for years. So it boils down to: who do you want to trust more? For me, Telegram felt like the lesser evil. But again — it’s your choice. I’m not telling you to trust Telegram. I’m just saying: here’s another option, do with it what you like. And if you want to dive deeper, check out the FAQ section where I go through all these questions in detail. So my thought was simple: 👉 If I’m anyway trusting a company, I’d rather trust Telegram (with unlimited space, no ads, no AI snooping) than Google(Google, which builds entire business models around data.). Still, it’s your call. I’m not here to sell you Telegram. I’m just here to hand you the option. 🛡️ Transparency First I don’t want you to blindly trust me either. Here’s how CloudGallery works: Your bot token & chat ID are stored securely in Android keystore (AES encryption). Your photos go directly to your Telegram account — no middle servers. I don’t track you, I don’t log you, I don’t even know who uses this app. The app is open source. You can read the code yourself. Now, let me be fully transparent about limitations too: Bot API has
