DIGITAL FOOTPRINT

Web traffic, app reach and release cadence

How the South Korea companies on this page show up online: the sites people visit, the apps they install, and how often those apps ship.

Most-installed apps

61 of these companies (16.5%) publish at least one Android app — 115 apps in all, carrying 20M installs between them.

Installs are lifetime totals to date at the June 2026 store reading — a measure of reach, not of people using an app today.

App reach by segment

The busiest app inside each of this page’s own segments, with the quarterly release trend behind it (2023Q3–2026Q2).

Oil & Gas Tech2224.3K가스락 - 가스비는 줄이고, 혜택은 더하고 224.1K
Facility Management Tech40205.6K스포패스 37.7K

A company can carry several segment tags, so these rows overlap and should not be added together. Trend lines are zero-based and share one quarter grid, so a flat line is a quiet segment, not a missing one.

Release cadence by quarter

New apps published, beside apps whose most recent update landed in that quarter — the second bar is how much of the shelf is still being maintained.

2023Q1: 12023Q1: 02023Q12023Q2: 22023Q2: 12023Q22023Q3: 12023Q3: 02023Q32024Q2: 32024Q2: 32024Q22024Q3: 22024Q3: 52024Q32024Q4: 32024Q4: 12024Q42025Q1: 12025Q1: 32025Q12025Q2: 42025Q2: 12025Q22025Q3: 12025Q3: 122025Q32025Q4: 32025Q4: 122025Q42026Q1: 32026Q1: 162026Q1

Darker bars are new releases, lighter bars apps updated. 56 of 115 apps carry a release date. The series ends at 2026Q1, the last quarter that closed before the June 2026 reading.

UNDERSTAND THE LANDSCAPE

Energy Tech in South Korea: key questions

Clear definitions for making better comparisons.

What does this landscape measure?

It measures the tracked company ecosystem, recorded funding, hiring and other available evidence. It is not a market-size estimate.

Can segment counts be added together?

No. A company can belong to several segments, so segment counts and funding can overlap.

What does a missing figure mean?

A dash or unavailable panel means the current reviewed source snapshot does not support that figure.

Company ecosystem snapshot: 3 September 2026. Funding is recorded in USD; filed accounts retain their stated currency and reporting basis. Each section identifies its own coverage. The news and research behind these sections is explorable in Prism.
