At first glance Rosie looks like the cheaper choice: $49 a month for 250 minutes. That's a lot of minutes for the money. But if you want callers booked into your calendar during the call, that starts on Rosie's $149 Scale plan. Cally24 is $99 a month with 240 minutes, and it books callers straight into your calendar on its one plan.
Prices checked October 25, 2026 on Rosie's pricing page, including its FAQ. Prices change, so check there before you buy.
Why booking on the call matters
Most callers want one thing: a time. When the receptionist books them while they're still on the phone, the job is in your calendar before they hang up. When it can't, you get a message and the follow-up is on you, often hours later, when the caller may have found someone else.
So for a business that lives on appointments, the real price is the plan that books. On Rosie, that's the $149 plan.
What booking costs
Here are three example months, each with booking during the call:
| Your month, with booking | Rosie | Cally24 |
|---|---|---|
| 100 minutes | $149 on Scale | $99 |
| 240 minutes | $149 on Scale | $99 |
| 400 minutes | $149 on Scale | $145.40 ($99 + 160 × $0.29) |
Up to about 400 minutes a month, Cally24 costs less with booking included. Rosie's Scale plan covers up to 1,000 minutes, so for a very busy phone it can come out ahead.

Where Rosie is strong
If you mainly need your calls answered and messages taken, Rosie's $49 plan gives you 250 minutes for little money. It answers in English and Spanish on every call, offers a 7-day trial and has apps for iOS and Android. If you use Google Calendar or Calendly and get lots of calls, the Scale plan's 1,000 minutes go a long way.
