A small studio in Ilford making quiet Android apps that work without a signal, without a login and without ads.
Everything poured on this site is alcohol-free, and so is every recipe in the app.
A house book of mocktails
You open the fridge and find half a lemon, a carton of juice and a bag of frozen berries. Mixjournal tells you what that can become. It is a calm, offline book of original alcohol-free drinks, each one written in plain language.
Browse by flavour, style or occasion, from brunch to a film night, or search by a single ingredient. Every recipe card notes how the drink tastes, the glass it wants, how hard it is and how long it takes, with a sweetness dial, measured ingredients and a garnish. A step-by-step view walks you through one move at a time, and scaling the servings recalculates every measure.
My Pantry is where it gets clever. Tick the juices, syrups, sodas and fresh things you keep at home, and the app shows every drink you can make right now, plus the ones you're a single ingredient or two away from, with exactly what's missing. Missing things go onto a shopping list you tick off in the shop.
Ounces or millilitres, a look you like, favourites kept close. No account, no ads, and it all works offline. Recipes carry simple kitchen notes on allergies and on getting a grown-up's help with the blender or the hob.

Sparkling water is only fizzy because carbon dioxide is pressed into it. How much gas the water can hold depends on two things: the pressure of the gas above it, and how cold it is. Move the sliders and watch the capacity change. The curve uses Henry's law with the measured temperature dependence for CO₂ in water.
A fridge at 4 °C lets water hold about 1.7 times as much CO₂ as a kitchen at 22 °C. Keep a bottle at 2 bar of gas in the fridge and it holds about 5.4 g per litre. To keep that same amount at 22 °C you'd need about 3.4 bar.
Once the drink is poured into an open glass, the only CO₂ above it is the trace in the air. At that level water holds well under a milligram per litre, about a hundredth of one percent of what the cold bottle held. That's why every glass goes flat in the end, and why a cold glass takes longer to get there.
What's not here: no recipes, no pantry and nothing to mix. The model treats the drink as plain water, so it leaves out how sugar and fruit acids nudge the numbers, and it doesn't show how fast bubbles escape once the cap is off. The drinks, the pantry and the "what can I make" screen live in the app.
