Reading a small, fast-expiring OTP off a notification banner is hard if your eyesight isn’t what it used to be. BigOTP catches the code as soon as it arrives and puts it in a floating bubble in large digits, then reads it aloud digit by digit so it’s impossible to miss or misread. A full-screen mode adds a countdown timer, and transaction OTPs get an extra warning with the amount called out.

It works entirely offline, doesn’t collect any data, needs no account, and is free with no ads. Built with India’s banking and payment apps in mind — SBI, HDFC, PhonePe, Google Pay, and the rest — and designed to work well with TalkBack and system accessibility settings.
