If you're looking for a text message reminder service in the UK, your options range from complex enterprise solutions to simple personal tools. Here's a straightforward overview.
What's out there
NHS and medical reminders: Many GP surgeries use automated SMS for appointment reminders. These are one-way — you can't interact with them.
Business SMS platforms (Twilio, MessageBird): Powerful but designed for developers. You'd need technical skills to set up reminders for yourself.
Calendar apps with SMS: Google Calendar can send SMS reminders, but only for calendar events — not recurring tasks. And Google has been scaling back SMS features.
Dedicated reminder apps: Many exist, but most send app notifications rather than actual text messages.
What's different about again
again is specifically designed as a personal SMS reminder service for recurring and one-off tasks. No app to download. You set up tasks on the website or by texting ADD, and it sends you real SMS messages when things are due.
The key difference: it's two-way. You reply DONE, SNOOZE, or SKIP via text. The whole system lives in your messages app. It's designed for UK users, with a UK phone number, UK pricing (free for 1 task, £7/month for unlimited), and UK-friendly copy.
