A collection is data you can’t see by scrolling
For a collector starting with three pens and five bottles of ink, a simple list is often sufficient to keep track of inventory. However, as the collection grows into dozens of pens and a vast “ink swamp” of colors, a flat list—whether on paper or in a basic digital note—begins to lose its utility. At a certain scale, the most important questions about a collection cannot be answered by merely scrolling through a list of names.
As developers of recording tools, we recognize that a large collection eventually becomes a dataset that requires aggregation and visualization to be understood. A list can tell you that you own a specific bottle of teal ink, but it cannot easily show you which brand you actually favor over time, how your usage patterns have shifted over the last twelve months, or whether a new ink you are considering is close enough to one you already own to be redundant. These insights require moving beyond raw entries and into the realm of statistics and side-by-side comparison.
What the statistics view shows
The purpose of a statistics view in a management system is to transform individual logs of “loads” and “cleans” into a meaningful overview of your hobby activity. Based on the design of modern collection trackers, there are four primary ways to visualize this data.
| Stat | What it shows |
|---|---|
| Load/Clean Counts | The total number of times you have performed a loading or cleaning action across your entire collection. This quantifies the overall level of activity in your hobby. |
| Monthly Chart | A bar graph showing your loading activity over the past 12 months. This helps identify seasonal trends or periods where you were particularly active in rotating your colors. |
| Brand Breakdown | A distribution (often a pie chart) showing how your collection splits across different manufacturers. This reveals your true brand loyalty versus what you might assume you own. |
| Top Pens/Inks | A ranking of your 5 most-used pens and inks. By aggregating every “load” action in your history, the system identifies which tools are your genuine “daily drivers.” |
Why aggregate statistics need a real collection to be useful
While statistics are a powerful tool for insight, they are fundamentally a “growth feature”. From a management-design perspective, aggregate data only becomes meaningful once there is enough history to reveal a stable pattern.
For a brand-new collection with only a handful of entries, a brand breakdown or a top-5 list won’t show a trend yet; it will simply mirror the few items you just registered. This is why we categorize statistics as an advanced management feature rather than a day-one necessity. As you build a habit of recording every ink change and pen cleaning, the data accumulates. Over months and years, this historical log transitions from a simple diary into a primary source for collection analysis, allowing you to see the actual trajectory of your hobby rather than relying on a vague mental impression.
Comparing up to 8 inks side by side
One of the most frequent challenges for ink collectors is the “near-duplicate” problem: the tendency to buy multiple inks that, while technically different, appear virtually identical when used. To address this, we prioritize a visual color-comparison feature over a simple text search.
This feature allows a collector to select multiple inks from their collection—up to 8 at once—to view their digital color chips together in a single view. This side-by-side display is a functional tool for several scenarios:
- Preventing Redundancy: Before buying a new ink, you can compare its color (based on your research) against the closest matches in your existing library.
- Selection Support: When deciding which ink to load next, you can view your top candidates side-by-side to see which hue best suits your current mood or the paper you intend to use.
- Sharing and Documentation: The comparison view can be shared as an image, providing a convenient way to document a specific color palette or show the nuances of a collection to others.
It is important to note that this comparison is a visual aid designed for the human eye; it does not rely on automated machine-learning “similarity scores”. Instead, it empowers the collector to make their own qualitative judgments based on the data they have recorded.
How Inkcho handles this
In the development of Inkcho, we specifically separated these analytical tools into our Pro version to serve collectors who have reached this “advanced management” stage.
Within the app, the Stats tab is accessible from the bottom navigation bar. For free users, this screen remains locked, serving as a placeholder until the collection grows large enough to warrant analysis. Once unlocked via the Pro upgrade (a one-time purchase of ¥980), the Stats tab provides the full suite of visualizations, including the 12-month loading chart and brand distributions.
Similarly, the Ink Color-Comparison Mode is a Pro-exclusive feature found within the Ink List. This mode allows you to enter a selection state where you can pick up to 8 inks to see them lined up horizontally for comparison. While the in-app purchase screen focuses on registration limits and notifications, both the Statistics and Color Comparison features are foundational parts of the Pro experience as detailed in our store description.
By providing these tools, Inkcho ensures that your collection data remains yours—completely private and stored locally on your device—while giving you the high-level perspective needed to manage a professional-scale inventory.

Summary
Collection management is about more than just maintaining a list; it is about gaining insight into your habits and preferences through statistics and visual comparison. By aggregating your loading history into charts and viewing your colors side-by-side, you transform raw data into the insights necessary to sustain and enjoy your hobby over the long term.
