For developers, calendar makers and anyone who sends reminders · Last updated: October 16, 2026
An Add-to-FollowFollow link lets a person send a reminder from your app, website, calendar, email, QR code or Shortcut straight into FollowFollow, where it will be spoken out loud when it's time. It's just a link. No account, no API key, no SDK, no approval from us.
If FollowFollow isn't installed, the same link opens a web page that shows the reminder and offers the App Store. On Android and desktop it shows that page too (FollowFollow is an iPhone app).
The simplest possible link:
A full one, with an exact time, a weekly repeat, the exact words to say, a place and your name as the source:
On a web page:
In an iOS app (Swift). Use the https:// link: it opens FollowFollow when installed and the web page when not, with no setup in your app:
Inside apps you may also use followfollow://add?… with the same parameters (it only works when FollowFollow is installed).
Open the link builder — type a reminder, copy the link.
All values are URL-encoded. Everything a FollowFollow share can carry is supported, except files (photos and voice memos can't travel in a link).
| Parameter | Meaning |
|---|---|
text | Required for reminders. What to remember, up to 300 characters. May include the time in plain words ("tomorrow at 3pm", "every weekday at 8"). |
at | Exact date and time, ISO 8601 with a time zone offset or Z: 2026-10-20T15:00:00-05:00. Shown to the user in their own time zone. |
repeat | daily, weekly, monthly or yearly. |
days | For weekly: mon,wed,fri (or 1–7, 1 = Sunday). Days alone imply weekly. |
message | The exact words FollowFollow will say out loud, up to 300 characters. Without it, FollowFollow writes a friendly message itself. Always shown to the user before adding. |
place | A place name, up to 120 characters. |
address | A street address, up to 300 characters. Looked up on the phone when no coordinates are given. |
lat, lng | Coordinates in decimal degrees. |
category | home, office, restaurant, shop, parking, scenicspot, item, idea, other. |
type | place saves only the place (needs place, address or coordinates), with no reminder. |
note | Extra details, up to 500 characters. |
source | Your product's name, shown to the user as "From …", up to 60 characters. |
Unknown parameters are ignored. Over-long values are cut. Unreadable dates or coordinates are dropped and the rest still works.
You may use this button image unchanged to point to an Add-to-FollowFollow link. Please don't alter it, recolor it, or use the FollowFollow name or logo in a way that suggests we made, sponsor or endorse your product. A plain text link ("Add to FollowFollow") is fine too.
