Things3 is a good application with many aspects.

However, there are two very large deficiencies.

1- No adding photos.

When taking notes, the photo is used a lot.

But they don't solve this deficiency.

They do not consider user demands.

We have been writing for two or three years.

They are not updated frequently.

2- Other big deficiency.

Any.Do has a nice calendar appearance in applications such as Ticktick.

Things3 are not in such a planning.

Currently, Akiflow has changed the Sunsama game.

In both sense, things are far behind.
