WHY UP↑SCALE › FOR WHOM? › AT HOME
The free Bluetooth kitchen scale app - for the scale you already have
Most kitchen scale apps work with one brand, want an account and stop at calories. This one connects to Bluetooth kitchen, food and coffee scales of many makers, runs in the browser of your phone, tablet or computer - and turns your scale into a nutrition calculator, carb counter, recipe guide, baking assistant, coffee coach and cocktail bar in one.
In short
UP↑SCALE is a free scale app in the browser for Bluetooth kitchen, food and coffee scales of many makers (and scales with USB or RS-232). It shows calories and carbs live with the weight, keeps a food diary with 8000+ foods, counts bread units and carb choices for diabetics, weighs recipes step by step (also from cups and spoons), helps with baking and sourdough, coaches espresso and pour-over and mixes 600+ cocktails. Free with no time limit, works offline, no account, no adverts, no tracking - PRO once for 89.90 EUR if you ever want more.
What a good Bluetooth kitchen scale app needs - and who has it
The questions to ask before you choose a smart kitchen scale with an app. The usual apps of the scale makers are made for one brand and a few jobs; here everything is in one free app.

Use the scale you already have - no new smart scale needed
The app runs our scale firmware in your browser and puts your scale in front of it: the virtual scale. No UP↑SCALE hardware, nothing to install.
- Bluetooth kitchen scales: many cheap and branded kitchen scales use a few common protocols the app knows - for example scales that show the names QN-KS (Arboleaf / Yolanda), smartchef (Chipsea), Lefu / Futula, Sencor, the scales of the FitDays / ICOMON app, Medisana, and scales with the standard weight profile. Look up your scale →
- Bluetooth coffee scales: Acaia, Felicita, Timemore, BOOKOO, Decent, Varia, DiFluid and more - with the full coffee coach.
- USB and RS-232 scales: a postal, bench or lab scale on the cable works too - and with our RS-232 adapter (the board under 15 EUR) any scale with a serial port becomes a wireless smart scale for the whole family.
- Two scales at once: the big scale for the flour, a fine one for yeast and salt - one sum, one recipe. How it works
A few scales cannot work in any browser app (encrypted ones tied to the maker's account, closed protocols): the list, with the reasons.

Kitchen scale apps: questions and answers
What should a good Bluetooth kitchen scale app do?
It should work with the scale you have, show what the weight means (calories, carbs, the next step of a recipe), work offline and without an account, and not cost every month. The UP↑SCALE app does all of this for Bluetooth kitchen, food and coffee scales of many makers - free with no time limit - and adds a food diary, carb units for diabetics, baking tools, a coffee coach and 600+ cocktails.
Is there a smart food scale app that is free?
Yes. The UP↑SCALE app is free with no time limit, without account, adverts or tracking, and it works offline. It connects to many Bluetooth kitchen scales you can already buy, so you do not need an expensive smart scale. PRO VIRTUAL is optional: once for 89.90 EUR or 24.90 EUR a year.
Which app works with my Bluetooth kitchen scale?
Many Bluetooth kitchen scales work with the free UP↑SCALE app: those that use one of the common protocols (for example QN-KS / Arboleaf / Yolanda, Chipsea smartchef, Lefu / Futula, Sencor, the FitDays / ICOMON scales, Medisana and the standard weight profile), Bluetooth coffee scales of many makers, and scales with USB or RS-232. Press CONNECT in the app and look for your scale, or look it up on every scale.
Can I use my iPhone as a kitchen scale?
Not reliably - a phone has no load cell, so apps that weigh on the screen only guess, and only for a few grams. Connect a real scale instead: on iPhone the UP↑SCALE app runs in Safari with a free extension, on iPad in a free Bluetooth browser - how to set it up.
How do Bluetooth kitchen scales work with an app?
The scale sends its weight several times a second over Bluetooth Low Energy, and the app reads it. The UP↑SCALE app does that straight in the browser (Web Bluetooth): no app store, no account, and the weight never goes through a cloud.
Is there a kitchen scale app for Android and for PC?
Yes: the UP↑SCALE app runs in Chrome, Edge or Opera on Android phones and tablets, Windows, Mac, Linux and ChromeOS, and it can be installed to the home screen or desktop. One PRO VIRTUAL licence covers 2 browsers, for example phone + laptop.
Does the kitchen scale app count calories and carbs?
Yes. Pick the food from 8000+ foods built in (they work offline), type the values of the package or (PRO) scan its barcode - calories, protein, fat, carbs, fibre and salt follow the weight live. Carbs also show as bread units, carb units or carb choices, with net carbs and FPU.
Do I need to buy a new smart kitchen scale?
Usually not. Many Bluetooth kitchen and coffee scales already work with the app, and any scale with an RS-232 port becomes a smart scale with our adapter (the board costs under 15 EUR). If you buy a new one, pick one that is on our list of scales that work.
