PlotPeek

Open CSV, Excel and Parquet on iPhone, iPad and Mac. Explore interactive analysis modes, keep work private on device, and export the view that matters.

Your data has a story. PlotPeek helps you see it in seconds.

Open CSV, Excel (.xlsx), or Parquet files and move from raw rows to a clear visual answer—without building a spreadsheet or writing code first. Choose the worksheet or range you need, then explore it in a focused native workspace for iPhone, iPad, and Mac.

SEE THE DATA FROM THE RIGHT ANGLE

Switch freely between 11 analysis modes:

• Time series
• RAW data
• Scatter + regression
• Regression Lab
• Correlation
• 3D explorer
• Histogram
• Box / violin
• Summary statistics
• Bar chart
• Pie / donut

EXPLORE INTERACTIVELY

• Zoom, pan, filter, and inspect exact values directly on a chart
• Compare columns and series across multiple files
• Resample, aggregate, and smooth time-series data
• Explore linear and polynomial relationships
• Review distributions, outliers, correlations, and descriptive statistics
• Personalize colors, axes, legends, line styles, and chart appearance
• Keep different questions organized in tabs and stacked graph workspaces

OPEN THE DATA YOU ALREADY HAVE

PlotPeek reads CSV, Excel, and Parquet directly. It detects common CSV delimiters and date formats, lets you select the right Excel worksheet or range, and keeps typed Parquet data ready for analysis without a conversion step.

Organize imported files into Projects with folders and tags, work with several sources at once, and optionally sync selected Project data through iCloud Drive. Save named Sessions to return to a useful workspace, or build repeatable import workflows for familiar files.

KEEP THE CONTEXT WITH THE WORK

Create Markdown Notes with folders, tags, search, attachments, and captures. Link a note to a graph, save a snapshot of the view that inspired it, and return to the underlying work later without losing your place.

EXPORT WHAT MATTERS

Turn an analysis into a PNG, JPEG, or PDF, or export the rows behind it as a filtered CSV. Customize the presentation and save reusable export presets so the result is ready for a report, presentation, message, or deeper analysis.

BUILT FOR APPLE DEVICES

PlotPeek adapts naturally to iPhone, iPad, and Mac, with touch, pointer, trackpad, and keyboard interactions designed for each screen. Your analysis stays on your device, with iCloud used only when you choose to enable it.

PlotPeek is made for the fast first look before deeper work. It complements spreadsheets, statistical software, and reporting tools by helping you understand a file quickly, export the useful result, and move forward.
