CLUSTER BLUETOOTH-CAR-CODES · 13 ENTRIES · EARLIEST ENTRY 2015-05-26
OBD2 car diagnostic apps
This cluster consists of mobile apps that connect to a car's OBD2 system via Bluetooth, USB, or Wi-Fi to read diagnostic trouble codes and display live sensor data, with some offering maintenance advice or Spanish-language guided diagnostics. The dated history is thin but present: one entry each in 2015-05, 2019-01, 2021-07, 2024-02, and 2025-05, suggesting a sparse, irregular pattern of roughly one new member every few years. All three traction leaders show zero activity signal, so no product clearly leads.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 13 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
