### 1/5 — Why is this app on AppStore?

*2024-03-31, version 12.4.9*

This paid app never worked. I downloaded without looking deeper. 5 stars out of 4 reviews! I would not recommend .

### 5/5 — Indispensable

*2023-12-13*

This app is a lifesaver for a naturally disorganised, somewhat forgetful and easily distracted night shift worker. It’s reliable and persistent and always gets me to work on time.

### 1/5 — Review

*2023-09-11, version 12.4.5*

It said it offered an alarm that went off until you turned it off it doesn’t and no one from the app has responded

### 2/5 — Calarm Sound doesn’t…..

*2023-05-01, version 12.4.4*

Calarm Sound doesn’t last long ENOUGH, & I can’t find a way to extend the sounds.

### 3/5 — No alarms, just alerts

*2020-12-30, version 12.3.1*

The difference between alarm and alert is that alerts play for a while and then stop, whereas alarm keeps going until you stop it. This app offers alerts, not alarms, so it's semi-useful.

### 5/5 — Great!

*2020-11-16, version 12.3*

Does what it’s supposed to.  If you’re like me and you can’t get up for your stupid 9am meeting, you need this!

### 1/5 — Wake up alarm not working

*2019-11-13, version 11.7.2*

I bought this app for one feature that it can wake me up 4 hours before my first meeting everyday. But it never rang my phone based on my first meeting. No my phone is not in silent mode.

### 2/5 — Disappointed

*2018-11-12, version 11.2.1*

Why can’t I choose louder and my own ringtones

### 4/5 — Nice little app

*2018-10-04, version 11.2.1*

I’m a student with a hectic timetable. My alarm times aren’t uniform week to week. Thanks to this app I no longer have to work out and set an alarm every evening.  

However I haven’t yet worked out a way to set an alarm to wake me up for my first lecture in the evening that won’t go off every day at the set time. 

It would be great if there was an alarm that recognised the first event of the day and went off even if it was past midday.

### 1/5 — Never miss a morning meeting

*2018-06-28, version 11.1.2*

Update: does not ring if phone is in silent mode.

Pretty cool app - lets you set an alarm automatically!!! before the first even of the day. 

So if your morning meetings start at different times you will never miss that odd meeting again. 

Let’s hope all goes well :)
