TL;DR: Before installing either, check exactly what contact and phone data the app requests and review its current privacy policy — caller ID accuracy is similar between the two, so the deciding factor is usually how comfortable you are with that data-sharing model.
Truecaller and getContact are widely used caller ID apps in India, both identifying numbers via a crowdsourced database.
What to Look For
Truecaller is the more established name in India, with a large local spam database built from years of crowdsourced reports and integration with several Indian telecom partners. getContact works similarly but has drawn more scrutiny for how aggressively it uploads a user's entire contact list to build its database.
Key Differences
Both apps rely on users uploading their phone contacts to power caller identification, which is the core privacy trade-off with this entire category of app, not unique to either one.
The Bottom Line
Before installing either, check exactly what contact and phone data the app requests and review its current privacy policy — caller ID accuracy is similar between the two, so the deciding factor is usually how comfortable you are with that data-sharing model.
