Talk to buyers. Keep your phone number private. NoNumber lets you have real voice conversations without sharing your personal phone number. With NoNumber for Marketplace, create a reusable link for something you’re selling and share it with your listing. Interested buyers can request a private call, and you decide whether to Talk Now, Call Later, or Decline. Your phone number is never shown or exchanged. You can also create Personal NoNumber links when you want someone to reach you without giving them your number. They open the link in their browser and request a call—no app required for them. Use NoNumber for local selling, dating, networking, travel, introductions, appointments, recruiting, customer conversations, and other situations where exchanging a permanent phone number feels unnecessary. Optional subscriptions are available for users who need higher usage limits, longer calls, more completed calls, email relay usage, and scheduled link windows.

Verdict

The call

The clearest difference is review sentiment: NoNumber at 100% against Otro's 0%. NoNumber also leads on rating (5.0 vs 4.3) and update cadence (every 3 weeks vs every 3 months). Otro's advantage is ratings volume (6 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. NoNumber sells 3 in-app purchases, starting at $0.99 per month and Otro sells 6 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

UpkeepUpdate frequency
