COMPARE CALLS / VS SIDELINE · SECOND NUMBER APP

Hobb vs Sideline.

A second line on your phone for a low flat fee. That is the whole product.

THE HONEST VERDICT
Sideline separates work from personal for ten dollars. Hobb does that too, and then remembers everything you promised on the calls, ranks what needs you today, and drafts the reply.
WHERE SIDELINE SHINES
Cheap and simple, a second number on the phone you own
Auto-reply and business-hours basics included
No contract, quick setup
WHERE IT LEAVES YOU THE WORK
No AI, no notes, no follow-ups, nothing is written down for you
Very limited business features beyond the number itself
Nothing for email or WhatsApp

Side by side.
