(R)EVOLUTIONARY SCALES
Up↑Scale your scales!
We do not just add an app to a scale - we rebuild what a scale can do. Your verified trade scale gets statistics, ℮ checks and a built-in test suite, many scales and phones/displays work as one, recipes, ingredients, custom units and all kind of THINGS get saved directly on the scale - and even machines are controlled by it.
𝔹𝕀𝔾 𝕊ℂ𝔸𝕃𝔼 charge you thousands and tie you to subscriptions. Here you get the same power for free - or for a single payment, once and for good.
Start free for under 15 EUR (just the board) · PRO once 46.50 EUR · ENTERPRISE once 149.90 EUR · no subscription · no advertisements · works offline FOR EVER
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, 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, 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, it is a single payment of 46.50 EUR.
Why we lead - and what nobody else does
Simple counting, logging and converting - boring, and many apps can do that! But no other product worldwide that combines what you see here! This is the (r)evolution.
One scale, 25+ jobs
Weighing, counting, calculating, check-weighing, statistics, ℮ control, sorting, recipes, filling, portion, coffee, stockholding, sales, labelprinting, dryinbg, 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 sum up, calculate 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 its for 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 stays verified
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 will stay the legal reading required - and the app does all the rest!
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. Once for 149.90 EUR, no subscription.
Laboratories & pharmacies
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 seal of the scale - 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 (all editions, newest firmware): 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 - 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 time comes from the connected phone or computer. 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
Choose your scale
Two ways to get started: upgrade the scale you already have, or use one of our own smart scales. Both work with the same app.
RS-232 adapter
(DIY / 323)
Our firmware turns the small ESP32-C3 RS232 Adapter into a complete smart adapter for any scale with an RS-232 port - also your verified, legal-for-trade scale (METTLER TOLEDO, KERN, OHAUS, A&D, ADAM, SARTORIUS and many more). From ultra-micro balances (0.1 µg steps) to weighbridges, with multi-interval scales too.
board ≈ 13.50 EUR + PRO licence 46.50 EUR, once – ENTERPRISE & COMPLIANCE: only +103.40 EUR on top of PRO
232 UP↑SCALER
Legal for trade? Your verified scale + our app = ℮, statistics, labels! In LISTEN ONLY mode it never sends anything to your scale, and EXACT WEIGHT shows exactly the weight of your scale. No need to replace your working hardware.
This is basically just a small RS-232 dongle, combined with microcomputer and (soon) comes with a nice housing and branding. Until that, check out the TinyTronics board, which offer the same options for less then 15.00 EUR and is available for you today!
UP↑SCALE 420
3000g / 0.1g
Our own stylish weighing scales comes without batteries, displays or buttons - small, durable and cheap. Use it with your mobile or computer and enjoy all the options of the app. This one is perfect for kitchen and houshold.
UP↑SCALE 710
300g / 0.01g
Our 710 model is made for things like salt and superexact. And you can connect both scales in the same app if you want, just with a click! (Prototypes - not for sale at the moment.)
