4loAppThe follow-up reminder app that closes deals
80% of sales need five or more follow-ups. 4loApp makes sure you actually do them. Set a date on any client, get pushed the moment it's due, and call or WhatsApp in one tap.
Reminders tied to contacts
Every reminder is attached to a client — with their number, notes, and history. No context-switching.
Push the moment it's due
Today, tomorrow, next quarter — 4loApp pings you the second it's time to reach out.
One-tap call or WhatsApp
Tap the notification. Tap call or WhatsApp. Talk. Log a note. Set the next reminder.
Recurring follow-ups
Snooze, reschedule or add the next reminder in seconds — perfect for long sales cycles.
Notes on every touch
Every follow-up you complete becomes a note on the contact — full history, one screen.
Works offline
Add reminders and notes anywhere. Syncs to every device the moment you're back online.
Why a to-do app isn't enough for sales follow-ups
Generic reminder apps ping you at a time — but you still have to find the client's number, remember the last conversation, and open WhatsApp or the dialer. 4loApp collapses all of that into one tap, because the reminder lives on the contact itself.
Built for the 80% rule
Research shows most sales need five or more follow-ups, but most reps stop after one or two — usually because they forget. 4loApp exists to make forgetting impossible. Set the reminder once; close the deal on follow-up number seven.
Frequently asked questions
What is the best follow-up reminder app for sales?
The best follow-up reminder app is the one tied directly to your client contacts. 4loApp lets you set a follow-up date and reason on every contact, then pings you with a push notification the moment it's time to reach out — with call and WhatsApp one tap away.
How is this different from a to-do app or calendar reminder?
To-do apps and calendars remind you at a time, but not with the client's phone number, notes, and last conversation attached. 4loApp reminders are attached to the contact — tap the ping and you're on a call or in WhatsApp with all the context you need.
Do I need to install anything from the app store?
No. 4loApp is a Progressive Web App (PWA) — install it directly from your browser on iPhone or Android. No app store, no updates to chase.
How much does the follow-up reminder app cost?
Free for up to 50 contacts. Pro is $2.99/month for unlimited contacts, cross-device sync, push notifications, and CSV/JSON import & export.
