Hey Product Hunt 👋
I’m Paul, and I’m excited to launch ReminderOS today!
Most reminder apps do the same thing: they notify you at a time you chose, and assume that’s enough.
In reality, that’s usually not how things get done. A few examples from how I use ReminderOS:
- I take vitamin C + D every morning. I’ve got a short heads-up before the actual reminder so I don’t just dismiss it and move on.
- If I need to return something, I star the email and it becomes a reminder.
- For the gym, the useful reminder isn’t the workout — it’s the one before it that tells me to pack my bag and get ready.
That’s the idea behind ReminderOS- not just “remind me at this time” but “help me actually follow through”.
You can keep things simple, or get very specific with schedules (every 3 days, certain weekdays, etc.). Everything syncs via iCloud, so no accounts and no tracking.
I didn’t set out to build a reminders app, I just wanted something that works properly day to day.
How do you find reminder apps? What's working and what's not working?
I use reminders all the time. The idea of setting “pre”-reminders isn’t a bad idea at all. Curious how it’d affect me.
Love the idea of reminding before the reminder !! that’s actually what makes things happen in real life. Most apps assume one notification is enough, but it rarely is. Congratss !! will definitely try it
is it follow ups or sub-reminders? sub-reminders could be really effective actually
I love the multiple reminders! Thats whats missing from my google calender/iphone notifs!
i mostly use reminder for work thing (and for that i use apple reminder and so far so good) but yeah loved the thought and idea behind it, we all need 1 extra push sometimes
