For apprentices and improvers
49 free trade calculators, a diary for the odd job on the side, and one place for your kit and its serial numbers. Build the habits while you're learning, and the day you go out on your own you're already set up.
Free to start · No card · No download needed — works in your browser
The bits of the job nobody teaches you at college.
Voltage drop, gas rate, radiator BTU, pipe sizing — you need the answer now, not after asking the gaffer twice. TradePlanr's trade calculators are free for everyone, forever, and the toolbox in the app works offline on site.
You've spent a fortune building up your kit, and if it goes walkabout from the van, nobody's got the serial numbers. Log every tool once — make, model, serial and calibration dates — and you've got the record when you need it.
Fitting a mate's mum's shower for "whatever's fair" is how arguments start. Write it up as a proper itemised quote so everyone knows the price before you pick up a spanner.
Addresses in texts, photos mixed in with your holiday snaps, notes on your hand. Keep the notes and photos against the job they belong to, so you can find them again.
Most of it is on your phone, works without signal, and costs nothing until you're running your own jobs.
49 calculators across electrical, gas, heating, refrigeration and general trade maths, with the electrical ones referenced to BS 7671. No account needed to try them in your browser at tradeplanr.com/calculators.
Every tester, analyser and power tool in one list, with serial numbers and calibration due dates. TradePlanr flags anything that's overdue or due in the next 30 days.
Day and week views with AM, PM and all-day slots, and the client's details on every booking. It works offline and syncs when you've got signal again.
Before and after photos, what went in, the gate code. It's all stored on the job record, not lost in your camera roll.
It's your account on your phone. When you go out on your own, add your business name, logo and rates and you're sending branded quotes and invoices the same day.

The calculators and toolbox are free, so it costs you nothing. An apprentice who checks their own sums before asking is one who learns faster and asks you less.
Getting them into the habit of logging their kit and keeping job notes now is the cheapest way to make sure they're organised when they're working without you looking over their shoulder.
The 49 calculators and the toolbox are free for everyone, forever, and you can start the rest of the app free with no card. Pro is £9.99 a month or £99.99 a year with a 7-day free trial. You only need it when you're sending quotes and invoices, taking card payments and running your own diary properly.
Most of TradePlanr is for running your own jobs, so you won't need all of it yet. The free calculators and keeping a record of your kit are useful from day one. If you're doing paid jobs on the side, have a look at the side-jobs page, because that's where things like writing quotes start to matter.
Yes. The calculators and the job diary work offline, so plant rooms, basements and new-builds aren't a problem. Everything syncs once you've got signal again.
You carry on with the same account. Add your business details, logo and usual rates, and you can send your first branded quote or invoice that afternoon. Upgrade to Pro when you're ready to send.
Electricians, gas and heating engineers, plumbers, builders, plasterers, roofers, joiners, decorators and renewable installers all use it. The calculators lean towards electrical, gas and heating, and the diary, quotes and invoices work for any trade.
Start free in your browser or on your phone. There's no card to enter, and the calculators are yours to keep.
