### 1/5 — Utter failure

*2026-03-22*

I’ve tried the conversion multiple times and keeps failing and keeps defaulting to incorrect dates

### 4/5 — The new version is starting to get better.

*2025-04-11*

Getting easy again with the scroll vertical dial…easy and quick as it use to be. Can be much better - and as original. Should be more forthcoming the whole thing and it should wiggle up and down when scrolling the dial.

### 1/5 — Update has destroyed the app

*2025-03-28*

Spoilt a good app. I’ve now removed the app

### 1/5 — The Worst!

*2025-03-21*

Was MUCH better before update

### 3/5 — Saka calendar

*2025-03-15*

Earlier Saka calendar was there, but don’t know why it has been removed now? Please add.

### 2/5 — Now useless

*2025-03-15*

In the past, the wheel arrangement allowed me to search and compare dates as they corresponded. Now I can see only today, absolutely useless. Looking for another option. Another “improvement“ into obsolescence.

### 1/5 — Liked it before the most recent update.

*2025-03-08*

Prefer the previous rolling style backward and forward to find dates.  Just a simple spin was all it took.  Now it's practically impossible and very time consuming to find a much older date on the calendar or to go further than a few months into the future.  Very disappointed with this new format.

### 3/5 — The new version is not as good as original.

*2025-03-05*

NOT as easy and quick as it use to be. Can be much better - and as original.

### 5/5 — Does it’s purpose perfectly

*2025-03-05, version 3.0.0*

Great and simple app

### 3/5 — Not enough

*2024-04-03*

While I very much like this calendar converter in every way, I am quite disappointed that it doesn’t include important Hebrew holidays. This would be a five star app if it had those.
