One calendar for every reminder

Relayr is generic by design: a phone number, a date, and an optional reference or name.

Car service & inspections

Inspection (ITP), insurance (RCA) and service reminders, sent before they expire.

Clinics, salons & studios

Appointment reminders that cut no-shows without a paid SMS plan.

Invoices & payments

Friendly nudges before a due date, with the invoice number as reference.

Personal & family

Birthdays, renewals, subscriptions — anything you shouldn't forget.

From calendar to sent SMS in three steps

Write your template once

Use {{name}}, {{reference}}, {{date}} and {{workspace}} — Relayr fills them in for every message.

Tap a day on the calendar

Add a phone number and time. Name and reference are optional. Or import a whole CSV at once.

Your phone delivers it

Android sends at the exact time on its own. iPhone runs a Shortcut you trigger or automate.

Everything you need, nothing you don't

Full-screen calendar

Month, week and list views that fit any screen, from phone to desktop.

Android automatic sending

Connect the free SMS Gateway app once; every message goes out exactly on time.

iPhone Shortcuts

Three ready Shortcuts: test without sending, send chosen days, or run daily, weekly or monthly.

Smart templates

One base message, personalised with name, reference, date and your business name.

CSV & JSON import

Bring your existing reminders with downloadable templates and a default send time.

Private by default

Phone numbers and gateway credentials are encrypted before they are stored.

Pick the phone you already have

Fully automatic

Android

Install the free SMS Gateway for Android app, paste its credentials in Relayr, and every scheduled SMS is queued on your phone for its exact time.

Best for hands-off sending

One tap or an automation

iPhone

Relayr builds an Apple Shortcut for you. Run it by hand for chosen days, or let a Shortcuts automation send everything that's due every day, week or month.

Best if your business number is on an iPhone

Encrypted before storage

Your contacts' phone numbers stay private

Every phone number and gateway credential is encrypted with AES-GCM before it's saved, with a key kept separately from the database. Numbers are only decrypted to send a message or when you press “Show phone number”. Bot protection guards every sign-in and form.

Frequently asked questions

Is Relayr really free?

Yes. Relayr doesn't charge per message. SMS are sent from your own phone, so they use your normal mobile plan — often unlimited SMS in Romania.

Does it work on iPhone?

Yes, through Apple Shortcuts. iOS doesn't allow any app to send SMS silently in the background, so you run a Relayr Shortcut with a tap or from a Shortcuts automation (daily, weekly or monthly). It sends every message that's due.

How does Android send at the exact time?

You install the free, open-source SMS Gateway for Android app. Relayr queues each message on your phone with its exact send time, and the phone sends it even if Relayr is closed.

Can I import reminders I already have?

Yes. Download the CSV or JSON template, fill in phone numbers and dates, and upload it. Dates without a time get a default hour you choose. Past dates are skipped.

What do I need to fill in for each message?

Only a phone number and a date. Reference (like a plate number or order ID) and name are optional — or you can make them required in Settings.

Is it available in Romanian?

Yes. The whole app, templates and emails work in Romanian and English.
