The bus operator retired its own app: Mobiett was replaced on 31 August 2022 by 'Where Is My Bus'. The same GPS feed is published as GTFS on the city portal, so rival apps can run on it too.

The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Istanbul's public bus operator İETT tracks its fleet with onboard GPS/AVL telemetry and surfaces live vehicle positions, stop-level arrival predictions and route information through its official app — originally 'Mobiett', replaced on 31 August 2022 by 'Otobüsüm Nerede' ('Where Is My Bus') — covering hundreds of bus lines citywide. İETT also publishes GTFS schedules and real-time vehicle web services on İBB's open data portal, letting third-party apps reuse the same feed.
