Calculate, see, compare
Calculators, visualisations and technical drawings. Every tool states the formula and the standard behind it, and your data never leaves your browser.
- Tools for everyone
Free calculators and visualisations from many industries. We keep adding more.
- Solutions for companies
Configurators and calculators on your website, with your products and prices.
- Software for old machines
A new program to replace old software that can no longer be updated, for machines that still run.
Industries
We always build a tool for a specific company. Below are examples from a few industries. Yours is not listed? Tell us what you still calculate or draw by hand.
Electrical engineering and power
8 tools · 3 examples
Equipment manufacturers, wholesalers and design offices. Tools designers search for online, which a manufacturer can host on its own site.
Earthing and lightning protection
- CalculatorTechnical drawing
Ring earth electrode calculator
Draw the building outline and place the down conductors. Get the ring length, joints and resistance.
Editable plan · resistance · A4 printMethod: R = 0.6·ρ/√A (DEHN, table 5.5.1) · BS 7430 - CalculatorVisualisation
Soil resistivity by the Wenner method
Enter the meter readings, compare apparent resistivity and carry the result into the earthing calculation.
Measurement series · chart · data transferMethod: ρ = 2π·a·R (Wenner method) - CalculatorTechnical drawing
Earthing resistance calculator
Calculate the resistance of a single rod, a line or a square of rods and compare the variants.

Earth rod resistance vs length
See how the resistance of a single vertical rod falls with every metre and when driving deeper stops paying off.

Earthing conductor size for fault current
Size an earthing conductor for the fault current and compare five materials and tape dimensions.

What we can build
- Product selection from your catalogue
The designer enters the operating conditions and the result points to a specific product from your range, with its data sheet.
- Kit configurator
The customer builds a kit from parts that fit together and sends an enquiry with the item list ready.
- Printout for the design file
Drawing, calculations and assumptions on one A4 page with your logo, ready for the design documents.

Manufacturing and machinery
3 examples
Plants where machines outlive their software, and companies that make to measure.
What we can build
- New software for an old machine
The vendor stopped shipping updates, but the machine still runs. We write software that does what the old one did, runs on a current computer and can be developed further.
- Made-to-measure product configurator
Doors, windows, furniture: the customer picks sizes and finishes and sees a drawing and a quote, while production gets the cutting list.
- Cutting plan and material use
The tool lays parts out on a board or a bar and shows the waste before you order material.
Construction and building services
3 examples
Building material manufacturers, contractors and building services designers.
What we can build
- Material quantity calculator
How many bags, rolls or litres a given area needs, with an allowance and an order list, based on the manufacturer’s technical data.
- Floor plan with calculations
The customer draws a room or building outline and the tool works out lengths, areas and parts. Our ring earth calculator works this way.
- Early estimate on your site
A cost range from a few questions, using your rates, before the customer calls.
Dentistry
3 examples
Dental clinics and dental laboratories.
What we can build
- Treatment plan calculator
The patient picks the scope, for example an implant with a crown, and sees an indicative cost from the clinic’s price list and the number of visits.
- Treatment stages on a timeline
A visual of what happens at each visit and how long healing takes. The dentist sends it to the patient after the consultation.
- Orders for the dental lab
The clinic picks the type of work, material and shade, attaches scans and checks the order status without phoning the lab.
Transport and logistics
2 examples
Hauliers, forwarders and warehouses.
What we can build
- Trailer loading planner
Pallets and loads laid out on a trailer plan, with loading metres and a weight check.
- Electronic transport documents
A consignment note issued in the browser and signed by the sender and the consignee on their phones.
Case study: eCMR One: electronic consignment note
Car workshops
2 examples
Garages, tyre shops and car washes that want to fill idle slots.
What we can build
- Booking idle slots
The workshop lists a free slot in seconds and a driver books it without calling.
- Service cost calculator
The customer picks the car and the job, for example a tyre change with balancing, and sees the price from your list.
Case study: MotiGo: bookings in idle time
Accounting firms
2 examples
Firms that handle many clients and want less retyping.
What we can build
- Calculator for the firm’s clients
A comparison of tax options or social contributions on the firm’s site, with an invitation to talk.
- Invoicing the firm’s clients
A whole month of invoices issued in one action and sent to KSeF, with payments matched from the bank statement.
