BigOTP

BigOTP is a free accessibility app built with care for elderly users, people with low vision, and anyone who struggles to read small OTP codes quickly. When your bank, payment app, or any service sends you a one-time password, BigOTP instantly: • Pops up a floating bubble with the code in large, high-contrast digits — right over whatever you're doing • Reads it aloud digit by digit — "4... 7... 2... 1..." • Keeps the bubble visible so you can see the code while you type it elsewhere • Automatically clears the code once it expires ━━━━━━━━━━━━━━━━━━━━━━ WHO IS BIGOPT FOR? ━━━━━━━━━━━━━━━━━━━━━━ • Elderly users who find small notification text hard to read • People with low vision or visual impairments • Anyone who loses the OTP before they can type it in • Users of screen readers — BigOTP works alongside TalkBack ━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━ 1.
