Callstack - Cold Call Lists

Callstack makes cold calling simple. Import your existing call lists from Excel or CSV and work through them one by one - without a bloated CRM, without an account, and without complicated setup. During a call session, Callstack only shows you the next lead. Make the call, add a note if needed, set the right status, and move straight to the next one. Your workflow in Callstack: - Select an Excel or CSV file - Automatically detect and map columns - Automatically filter duplicate phone numbers - Call leads one by one - Save statuses and notes immediately - Keep callbacks and appointments clearly separated Available statuses: - Open - No anwser - Call back - Not interested - Appointment Callstack is intentionally not a traditional CRM. It focuses on one job: helping you work through call lists quickly and clearly. Your lead and sales data stays stored locally on your device. No Callstack account is required to use the app. You can import as many lead lists as you want. The first 30 processed leads are free. After that, Callstack Pro unlocks unlimited processing. Callstack is ideal for freelancers, sales teams, and anyone who regularly works with cold calls or structured outbound calling.
