Slack's /remind works in Slack. NagMeLater works in WhatsApp.
Scores are for the personal WhatsApp reminder use case specifically, not overall product quality.
Slack's built-in /remind command is a handy team tool for workplace reminders. But it only fires inside Slack, not WhatsApp. For personal reminders on WhatsApp, NagMeLater is the right tool. For team reminders within a Slack workspace, /remind does the job without any extra cost.
Short answer: NagMeLater wins for WhatsApp reminders. Choose NagMeLater if you want personal reminders on WhatsApp, not Slack, you don't have a Slack workspace or you want a reminder bot that works outside of work hours; choose Slack Reminders if your team already uses Slack all day, you want to set reminders for other team members via Slack or you need work-context reminders inside your team workspace. Slack's built-in /remind command is a handy team tool for workplace reminders. But it only fires inside Slack, not WhatsApp. For personal reminders on WhatsApp, NagMeLater is the right tool. For team reminders within a Slack workspace, /remind does the job without any extra cost. On price, Slack Reminders is Free / $7.25/mo per user, while NagMeLater is free for 7 days, then $1.99/month or $59 for life. On the five-part scorecard above (delivery, setup, language, price, platforms) NagMeLater averages 5.0/5 to Slack Reminders's 3.0/5, and the gap is widest on WhatsApp delivery (5 vs 1).
Inside a workday, Slack's /remind is genuinely clever: no new tool, reminders created without leaving the conversation that caused them, channel reminders that nudge a whole team, and Slackbot follow-ups that work well for deferring messages. If your company lives in Slack and the reminder is about work, /remind me to review the PR at 3pm is fast, free on any Slack plan, and exactly where it should be.
Slack's boundary is Slack's hours. Personal reminders in a work tool mean your medication nag depends on opening the office. Evenings, weekends, and holidays, precisely when personal reminders matter most, are when Slack notifications are muted, guiltily ignored, or signed out entirely. Slackbot alerts also arrive quietly, one more line in a noisy sidebar. And when you change jobs, your reminder history stays behind on someone else's workspace. WhatsApp has no office hours and follows you between employers.

/remind is free inside whatever Slack plan work pays for, so for work reminders the price is unbeatable. NagMeLater's $1.99/month (after a free week) is for everything /remind structurally cannot cover: your life. The two do not really compete; they split cleanly at the work-life line. Renewals, family birthdays, prescriptions, and side-project deadlines do not belong in a workspace you might leave, and no personal reminder should require your employer's tool to fire.
There is nothing to migrate and nothing to uninstall to try this. The first reminder takes about 30 seconds:

Each of these becomes a WhatsApp message fired at the exact time you asked for.
For personal WhatsApp reminders, yes. Slack's /remind command works only inside Slack, you need an active Slack workspace. NagMeLater works for anyone with WhatsApp, with no workspace or subscription required. For team reminders within Slack, /remind is already built in and free.
No. Slack reminders fire as Slackbot messages inside your Slack app. They do not send notifications to WhatsApp. NagMeLater delivers reminders directly as WhatsApp messages.
Use Slack /remind for work reminders you want within your team's Slack context, "remind @channel at 3pm to submit timesheets". Use NagMeLater for personal reminders you want on WhatsApp, outside of the Slack workspace.
Yes. A common pattern: use Slack /remind for team and work reminders inside your workspace, and NagMeLater for personal or after-hours reminders that come through on WhatsApp.
Yes. Slack's /remind command is available on all plans including the free tier. The limitation is that Slack itself requires an active workspace subscription for team features. NagMeLater requires no workspace, just WhatsApp.
