Your scale + our adapter + our app
- Works with verified, legal-for-trade scales
- Statistics, labels, recipes, stock and sales log
- Several phones on one scale, several scales in one program
- Your data stays yours: no account, no cloud, no subscription needed, no adverts
- Works offline, once and forever!
Live demo: the button listens for the radio signal of every UP↑SCALE around you and replaces the weight above with their combined weight - live, from all scales at once. Nothing is connected, nothing is saved, and no data leaves your device.
You need: Chrome, Edge or Opera on a computer or Android phone, with the browser flag #enable-experimental-web-platform-features switched on (how), and the scale setting BLE for all turned ON. The same function is a short example script you can use in your own pages: HTML/JavaScript example.
The free version already does more than most paid solutions
Buy the board (about 13.50 EUR), install the firmware in your browser, open the app - and you can already weigh in all units, calculate prices, count, check-weigh, run recipes, print labels, use several phones and an extra scale, and calibrate. Every PRO mode (statistics, sorting, filling, tracking, density, sales log, stock) can be tried on your own scale for free, too.
No time limit, no account, no subscription. Many users will never need PRO. If you do some day: from 4.43 EUR a month, or a single payment of 119.90 EUR.

Already have a scale? One app for (almost) every scale
Bluetooth coffee and kitchen scales of many makers, lab and shop balances on USB or RS-232, scales that type into Excel: the app runs our scale firmware in your browser and puts your scale in front of it - the virtual scale. No UP↑SCALE hardware, and already the free version does more than most scale apps.
- Free, with no time limit: weigh in every unit - also in volumes like teaspoons, cups and millilitres - with prices and nutrition values, a nutrition diary, counting, check-weighing, recipes, the coffee timer, 600+ cocktails, labels, an extra scale, and the calculators: portions, baker's percentage and hydration, gold value, infusions ... And the full PRO for the first 3 days, automatically.
- One app instead of one per maker: maker apps work only with their own scales, PC tools need Windows next to the scale (lab packages cost thousands per balance), business software with a scale costs every month.
- Made for good: works offline, no account, no cloud, no adverts, no cookies, no tracking - the weight goes straight from your scale into your browser.
- No subscription needed: PRO VIRTUAL (statistics, sorting, filling, sales, stock ...) once for 89.90 EUR for 2 browsers, e.g. phone + laptop - or 24.90 EUR a year.
Why we lead - and what nobody else does
Simple counting, logging and converting - boring, and many apps can do that! But there is no other product worldwide that combines what you see here! This is the (r)evolution.
One scale, 35+ jobs
Weighing, counting, calculating, check-weighing, statistics, ℮ control, sorting, recipes, filling, portion, coffee, roasting, stockholding, sales, label printing, drying, tracking, density, cannabis, a test suite and many many further jobs ... one device, one app! Others sell one product per job.
Weigh, price and sell in one step
Weight, price, label and sales log come from one weighing and are saved on the scale - every record numbered and chained by the scale, the weight checked by the scale itself (a hand-typed weight is marked), so nothing can be changed unnoticed. It will remember when, how much and who took something, the costs and every unit. It sums up, calculates your profit and so much more! POS apps make you type the weight in and charge you every month for that!
A test suite for your scale
Repeatability, corner load, linearity, creep, warm-up and more, judged against OIML R 76 - with reports for the inspector's signature. We found no other adapter or app that offers this, and it is not only a tool for professional metrologists - self-checks can save you a lot of money and trouble!
Many scales, many phones, one program
Flour on the floor scale, chocolate on the tabletop scale and salt on the fine scale, the whole team on the same numbers! Connect with multiple phones or PCs, up to 6 scales at the same time, all wirelessly via Bluetooth LE! Industry builds this with cables and terminals for thousands - here it is free.
Machines that are controlled by the scale
Pumps and valves over ESP-NOW with a predictive cut-off that learns your machine's delay. Plus the Decent Scale protocol for espresso apps. Free example scripts included to build your own advanced machinery!
Your verified scale keeps its reading
If you want, our adapter only listens: switch on LISTEN ONLY and EXACT WEIGHT, and your legal-for-trade scale gets ℮ lot checks, Cp/Cpk statistics and labels - without touching its reading. Your scale display stays the legal reading - and the app does all the rest. What is legal?
Records you can prove - signed by the scale itself
With the ENTERPRISE & COMPLIANCE edition the scale keeps an activity log of who did what and when (the last 10,000 events, every entry chained to the one before by a SHA-256 hash), and it seals reports, PDF files and exports with its own key. A changed, removed or missing entry or file shows up when it is checked, and anybody can check a sealed file on up-scales.com/check - without the app, an account or an upload. From 13.00 EUR a month or once for 599.00 EUR, 14 days free to try.
Laboratories & pharmacies
The ⚕ compounding assistant from master formula to signed batch record, users with roles and passwords, a reason for every change, recipe approval by a second person, signed test reports and routine checks before use - records for audits under ISO/IEC 17025, GLP/GMP, 21 CFR Part 11 and EU Annex 11.
Food producers & packers
℮ lot reports, batch reports with lot numbers, check-weighing statistics and the daily routine check, each with a report number and the UP↑SCALE SEAL - for your HACCP plan, your customers and the weights and measures inspection.
Shops that count every gram
Every sale, every stock change and every calibration is written down with its user: dispensaries, jewellers, gold buyers and bulk stores can show where each gram went and that nobody quietly changed the scale.
Service companies & inspectors
Test the scales of your customers with the test suite and hand over a numbered test record that the scale sealed - the customer and any auditor can check that it was not changed after you signed it.
Cannabis social clubs
Harvest, drying, dispensing and destruction booked while you weigh - with member ID, lot and THC / CBD, and a tamper-evident record for the inspection.
For the private household
A nutrition diary with what you really ate, carbohydrate units for diabetics, baking and sourdough tools, recipes and coffee - the free version is usually all you need, with no account, no adverts and no subscription.
No record from a dead link (ENTERPRISE & COMPLIANCE): the scale sends its weight several times per second, also when nothing changes. If the data stop or the connection is lost, the app shows – – – and refuses ∑, sales and labels until fresh data come in (on by default, can be switched off; FREE and PRO lock when the connection is lost) - built to the loss-of-connection rule for weights sent to a computer (WELMEC / NTEP). How it works
Tamper-evident, not write-once: the memory of the scale and the files on a disk can still be overwritten or deleted, but this cannot go unnoticed. Keep the record files on read-only, backed-up storage, the tools to automate that are included in the software! The time comes from the connected phone or computer, but built-in protection and our device qualification take care of that. UP↑SCALE gives you the records - it makes no claim that you comply with a rule or that an authority accepts them. How it works · all logs at a glance
