Quick Answer
Notebooks are free and work fine for the occasional track day. Spreadsheets work if you enjoy building them. PaddockPro saves time and catches patterns you'd miss manually—but costs £$7.99/month. If you're doing 2+ track days a year and want to stop reinventing the wheel each session, it pays for itself. If it's genuinely once a year, keep your notebook.
Let's be honest: you can absolutely track your car's setup with a notebook and pen. People have been doing it for decades, and plenty of fast drivers still do.
So why would you pay for software? That's a fair question, and we're not going to pretend everyone needs PaddockPro. Some people genuinely don't.
Here's a proper breakdown of each option—what works, what doesn't, and when each makes sense.

The Real Question: What Do You Actually Need?
Features are nice, but let's cut through to what actually matters. Here are some real scenarios:
"I do 1 track day a year for a laugh"
You turn up, have fun, maybe adjust tyre pressures. You're not chasing lap times or trying to improve session-on-session.
→ Stick with a notebook. Seriously."I'm doing 2+ track days and keep forgetting my baseline"
You arrive at a track, can't remember what ride height worked last time, spend the first session experimenting with stuff you already tried.
→ PaddockPro (£$7.99/month)"I love building spreadsheets"
You've already got a 47-tab Google Sheet with pivot tables, conditional formatting, and you genuinely enjoy maintaining it.
→ Keep your spreadsheet. You've already invested the time."I want to get faster but don't know where to focus"
You've got data from multiple sessions but can't see the patterns. Did that spring change actually help? Was it the weather?
→ PaddockPro - data-driven pattern analysis"I forgot to check something and had a problem"
Loose wheel nut. Brake fluid not bled. Forgot the spare parts. You've had that sinking feeling at the track.
→ PaddockPro - checklists built for this"Setup knowledge stays in my head"
You know what works at Brands but couldn't tell someone else. If you sold the car tomorrow, all that learning goes with you.
→ PaddockPro - get it out of your headHonest Take
If you're genuinely doing one track day a year, you probably don't need PaddockPro. A notebook works. But if you're doing 2 or more days? The time saved and setup consistency pays for itself fast. £$7.99/month is less than a set of brake pads.
What About Harry's Laptimer / AIM / RaceChrono?
Different tools for different jobs. Those apps are excellent at what they do—recording lap times, analysing driving lines, showing sector splits.
PaddockPro isn't trying to replace them. We're not a full telemetry or data acquisition system. What we do is everything around your track day:
- Before the session: What setup are we running? What's the checklist?
- During the session: Quick notes on car behaviour
- After the session: What changed? What worked?
- Between track days: What was our baseline? What did we learn last time here?
Think of it this way: Harry's tells you how fast you went. PaddockPro helps you understand why the car felt a certain way and what to try next.
Many of our users run both. They export their best lap times into PaddockPro session notes, giving them the full picture.
The Spreadsheet Problem
We should talk about spreadsheets specifically, because they're the most common "system" we see people using.
A well-built spreadsheet can do almost everything PaddockPro does. The problem is:
- Building it takes hours. Getting the structure right, the formulas, the dropdowns, the conditional formatting. Most people start enthusiastic and abandon it half-finished.
- Mobile experience is painful. Ever tried updating a spreadsheet on your phone in a paddock with gloves on? It's not fun.
- It doesn't understand context. A spreadsheet doesn't know that your E46 M3 has different setup parameters than a Caterham. It can't suggest "last time at Brands in the wet, you ran 2 clicks softer on the rear."
- You have to maintain it. Every time you want a new feature, you're building it yourself.
If you genuinely enjoy building spreadsheets, crack on. But if you started one that's now sitting half-abandoned somewhere in Google Drive... that's the person PaddockPro is built for.
"I had a 12-tab spreadsheet that I maintained religiously for two seasons. Then I missed one track day update and the whole thing felt out of date. PaddockPro is just... easier to keep current."
— Beta tester, Civic Cup racerThe Bottom Line
Here's our honest recommendation:
- 1 track day/year: Use a notebook. Don't overthink it.
- 2+ track days/year: PaddockPro pays for itself in time saved and setup consistency.
- Already have a working system: If your spreadsheet/notebook is genuinely working for you, keep using it. Don't fix what isn't broken.
We built PaddockPro because we were frustrated with notebooks getting lost, spreadsheets being clunky, and setup knowledge staying trapped in our heads. If that's you too, it might help. If it's not, there's no shame in a pen and paper.
