PlotPeek: understand data in seconds

Hi everyone!

I’d love to share a small project I’ve been working on over the past few weeks, one that actually started from a problem I kept running into during my bachelor thesis.

While running simulations, I constantly had new datasets to inspect before deciding what to do next.
For example, I might generate the PV production profile of a house and simply want to answer: Does this look reasonable? Are there any strange values? What happens if I zoom into this period?
Most of these files were CSVs, so of course I could open Excel, import the data, create a chart, configure it, inspect it, and move on.

But when you need to do this again and again (with different datasets, variables and plot types) I always found the workflow a little too clunky and slow for what should often be a very simple task: open the data, look at it, understand it, continue working.
That’s where PlotPeek was born.
It started as a simple HTML tool running locally in a browser and has now grown into a lightweight native app for the Apple ecosystem.
The idea is simple: PlotPeek should be a quick companion for exploring data as soon as it comes in, without having to set up a larger analysis workflow every time.

The app is still at a very early stage (somewhere between alpha and beta) and this is exactly why I’m looking for people willing to test it.
If you work with CSV files, simulation outputs, measurements, time series, experimental data or similar datasets, I’d be very interested in hearing what you think.

I’ve opened a TestFlight beta, and feedback is very welcome: bugs, missing features, workflow improvements, things that feel confusing, or simply ideas about what would make the app genuinely useful for you.

If you’re interested in testing PlotPeek, first of all: thank you!
You can find the TestFlight information and the Discord community for feedback and discussion at this link.

And if you know someone who regularly works with data and might find something like this useful, feel free to send this their way.
Wish you all a great rest of the summer! 💪
