Why a contact app beats a full CRM for individual salespeople
Full CRMs are built for teams: pipelines, dashboards, reports, seats. If you're a solo salesperson, freelancer, agent or SMB owner, all that admin is friction between you and the next call. 4loApp is the opposite: the fastest possible path from 'remember to follow up with Sarah' to 'ringing Sarah'.
Set up in under a minute
Sign in with Google, import your contacts (or add your first one), tag them, set a reminder, close a deal. No onboarding call, no admin console, no per-seat pricing.
Frequently asked questions
What is a sales contact management app?
A sales contact management app is a lightweight tool for salespeople to store client contact details, log notes, and set follow-up reminders — without the pipelines, dashboards and complexity of a full CRM. 4loApp is exactly that.
Is 4loApp better than using my phone's default contacts app?
Yes — for sales. Your phone's contacts app has no follow-up reminders, no notes, no hot/warm/cold tags, and no WhatsApp shortcut. 4loApp adds all of that in a phonebook-simple interface.
Does it sync across devices?
Yes. Pro users get cross-device sync, so your contacts and reminders show up on every phone or browser you sign into with Google.
How much does it cost?
Free for up to 50 contacts. Pro is $2.99/month for unlimited contacts, cross-device sync, push reminders, and CSV/JSON import & export.
