Three steps. Zero configuration.
A one-time setup. BigOTP needs to read notifications — it never touches your SMS history.
From your bank, payment app, or any service — BigOTP detects the code instantly.
A floating bubble shows the code in large digits and reads it aloud — right over whatever you're doing.
Swipe to browse — real screenshots from a Samsung Galaxy A03.
Designed for real people, not tech experts.
Large digits appear over any app the moment your OTP arrives — no need to switch screens.
"4... 7... 2... 1" — each digit spoken clearly with a pause in between.
When an OTP arrives, BigOTP opens a dedicated full-screen view with large digits and a countdown. Prefer bubble-only? Switch to compact mode in settings.
See exactly how many seconds remain — no more rushing or expired codes.
Shows the transaction amount and a clear "never share this code" reminder.
TalkBack-aware — steps aside when TalkBack is active so it can announce the code. Respects your system font size, contrast, and reduce motion settings.
SBI, HDFC, ICICI, Axis, Kotak, PhonePe, Google Pay, Paytm, Amazon Pay and more. A generic fallback also catches most other standard OTP messages.
No internet connection needed to display your codes. Everything is on your device.
