Yes. No error on my phone. But it's think related to the data you are adding.

Give me more info about stuff you are adding: odo?

Odo remind? Date remind?

Odo repeat? Date repeat?

It could be a bug, but just let me know what fields are filled, and what fields you are changing while editing. Simple reminder works without any problem. I'm adding them all the time, repeat reminds.

Current version is 5.4.4. Could you only confirm that you are using this version?

But it was working fine?

Coud you give me more info?

How to reproduce it?

You are using 5.4.4?

This idea is not new. I can say even more. For sure this will be added to the app. And I think that it should be near future.

How do you see this in Fuelio?

Additional flag in the cost (category - cost/income)?

Yes. I've marked it. It's a notification bug (convertion to miles is missing). Will be fixed.
