## Most critical reviews (5 lowest-rated)

### 1/5 — Clunky

*2020-06-21*

This is the most clunky app I have ever used.

Try to change dates.    No it just resets
Then if you turn day off.    On or off    It then let’s you change the date.
If you don’t delete the pre entered schedules it doesn’t let you change the dates at all.
And you want money for this you shouldn’t have ads or a fee it needs to be free for the lack of effort you’ve put in...

### 1/5 — Useless

*2020-02-01*

Free version is designed for 2037 calendar. Sampe calculations come with pop up “loading advertisement” never actually shows you the result. Complete waste of time. I wasted mine so you shouldn’t

### 1/5 — .

*2019-05-06*

Sh*t waste of my time

### 1/5 — Useless and outdated

*2018-12-06, version 1.5.4*

Only support 2037 and 2038 and doesn't support iPhone X screen.

### 1/5 — App for the future? Like the year 2037

*2016-04-01, version 1.5.4*

No matter what I try, the app refuse to move the date range to this decade. So, if this app is still around in twenty one years, I'll give it a go....
