Getting Started

inxdays helps you remember what matters without the hassle of managing calendars or setting alarms. The workflow is simple: create a reminder, pick a date, and we handle the rest.

1. Create an Account

Sign up at inxdays.com. Your free account includes unlimited reminders and email notifications — no credit card required.

2. The Dashboard

After logging in, you'll see your dashboard — a list of all your reminders sorted by event date.

Reminder Statuses

• Active — The reminder is live. Notifications will be sent at the dates calculated by the Reverse Spacing algorithm.
• Completed — All scheduled notifications have been sent. The reminder stays in your dashboard for reference.

3. Create Your First Reminder

Click "+ New Reminder" (or use the input at the top of the dashboard). Fill in:

• Title — what you need to remember (required)
• Description — any additional details (optional)
• Date — the event date

Hit save. inxdays automatically calculates the notification schedule using Reverse Spacing.

Managing Reminders

Viewing Your Reminders

The dashboard lists all your reminders, sorted by date (earliest first). You can search for a specific reminder using the search bar at the top.

Editing a Reminder

Click on any reminder in your list to open its detail view. Here you can change the title, description, date, or toggle individual notification channels (Email, Push, SMS).

Deleting a Reminder

From the reminder detail view, scroll down and click "Delete". The action is immediate and irreversible — all scheduled notifications for that reminder are cancelled.

Reminder Statuses

Each reminder has one of two statuses visible in the dashboard:

• Active — The reminder is live. Notifications will be sent at the dates calculated by the Reverse Spacing algorithm.
• Completed — All scheduled notifications have been sent. The reminder stays in your dashboard for reference but no longer triggers notifications.

How It Works — Reverse Spacing

inxdays uses an algorithm called Reverse Spacing to determine the optimal notification schedule for each reminder. Instead of a single alarm, you get multiple reminders spaced intelligently before your event.

The principle is simple: the closer your event date, the more frequent the reminders. The further away, the more spaced out — so you're never reminded too early or too late.

For example, if you set a reminder for "Renew insurance" 60 days from now, you'll be notified at 30 days, 7 days, 1 day, and on the event date itself. You're always in the loop without being spammed.

Notifications

inxdays supports three notification channels. You can enable or disable each channel globally in your settings, or per reminder in the detail view.

Email

Email notifications are always on and always free. Every reminder triggers email notifications according to the Reverse Spacing schedule. No setup required — emails are sent to the address you used to create your account.

Push Notifications

Browser push notifications deliver reminders directly to your device, even when the browser is closed. They work in Chrome, Firefox, and Edge on desktop and Android.

How to enable:

• Go to Settings → Notifications
• Click "Enable Push Notifications"
• Allow the browser permission when prompted

Key features:

• Free and unlimited
• Works across multiple devices (up to 5)
• Active device indicator shows which browser is subscribed

Push notifications do not work in Safari — Apple requires a native app for push. You can use Email or SMS as alternatives.

SMS

SMS notifications send a text message to your phone. Each SMS costs credits, which you can purchase in Settings → Credits.

Supported countries: France, Germany, Switzerland. More countries will be added as we grow.

How to set up:

• Enter your phone number in Settings → General
• Buy credits in Settings → Credits
• Enable SMS for your reminders
