Seven small iPhone apps, each made for one everyday thing.
Counting down, travelling, invoicing, eating, scanning, learning, lifting.
Seven apps. One everyday thing each.
Countdown Widget: Any Event
Days to Go & Memories to Keep
A countdown that never loses your days — and never holds a widget back. Add the day that matters, put it on your home screen, and watch it come closer. No limit on how many you keep, and nothing between you and the number.
Countdown on the App Store ↗BeforeGo: AI Itinerary Planner
Trip plans from screenshots
Screenshot a travel post, paste a link, or just type your plans, and BeforeGo files it into a day-by-day trip plan: the places worth seeing, the to-dos before you go, and each day the post lays out. Scan a ticket or booking confirmation and it lands on the plan too. Meanwhile the packing list writes itself from your destination and dates.
BeforeGo on the App Store ↗Smart Invoice & Estimate Maker
Quote, receipt & PDF generator
The fastest way for freelancers and small businesses to send professional invoices, estimates and quotes — and get paid faster with built-in payment QR codes.
Invoice Maker on the App Store ↗DailyCalorie: Calories Left
Calorie Budget & AI Food Scan
DailyCalorie is a calorie counter and food diary you fill in with your camera. Most calorie apps show you what you have eaten. DailyCalorie shows you what is left.
DailyCalorie on the App Store ↗Custom QR Code Maker & Scan
QR scanner, generator & design
Design a QR code people actually want to scan — and one that always scans. Most QR apps hand you a black square. QR Studio lets you shape it, colour it, drop your logo in the middle and set it into an illustrated poster — then checks, every time, that it still reads.
QR Studio on the App Store ↗Word Beast: AI Photo Words
Snap it. Learn it. Say it.
Point the camera at anything — an apple, a backpack, the dog — and Word Beast's AI tells you what it's called in English, with phonetics, meaning and an example sentence you can listen to and read aloud. Snap a page of English homework to see which answers deserve a second look.
Word Beast on the App Store ↗Repdex: Gym Workout Tracker
Lifting Log & Exercise Library
Repdex is a gym notebook that works the way training actually works: look something up, write down what you lifted, close the app. Twenty times a session, ten seconds at a time.
Repdex on the App Store ↗About go ka
Most apps try to do everything. Ours start from one small, everyday moment — the day you are waiting for, the charger you always forget to pack, the invoice that has to go out tonight — and try to get that one moment right.
go ka is an independent developer. Every app is free to download, none of them asks you to create an account, and the price of anything extra is shown before you pay.
Small apps. Everyday things.
Short answers to what people ask.
go ka is an independent developer making small iPhone apps for everyday things: a countdown widget, an AI trip planner, an invoice maker, a photo calorie counter, a QR code maker, an English vocabulary app for kids and a gym workout tracker. All seven are published on the App Store under one developer account.
All seven apps are free to download and can be used without paying. Extra features come with an optional subscription, and some apps also offer a one-time purchase. The price is always shown in the app before you confirm.
No. None of the apps asks you to sign up or create an account. Where an app syncs between your devices, it uses your own iCloud.
