How is this better than getting notifications for events on my calendar?

Tickles are fundamentally different from events. Events must happen on a certain date at a certain time. On the other hand, when a tickle is triggered, there is no reason why you should deal with it immediately. Instead, the items get sent to an inbox for processing at the appropriate moment. Tickler also does not clutter your calendar, such that you can trust your calendar to only have events.

How is this better than my phone's reminders?

There is no reason to be immediately notified of triggered tickles. Tickler sends your items to an inbox so that you can deal with them when it is most convenient to you.

What happens to my data?

All data submitted via Tickler is secured while it is being submitted and while it is being stored. Users will never be tracked and their data will never be exposed to third parties.

Will there ever be ads?

There will never be ads on Tickler.

I don't trust you with my data, can I still use Tickler?

Yes, tickler is free software, so anyone can host an Tickler server themselves. The code and instructions are available on Github.

Is there an Android or Iphone application?

Tickler is currently not available on Android or Iphone. This may change in the future if there is enough demand.

How do I use Tickler for "Getting Things Done" (GTD)?
