Good, would highly recommend
This is generally a pretty good app yeah. It seems to reliably play any YouTube video (or TikTok I think) as loudly as you like, and in most cases even myself an insomniac can wake up. As well, several other apps I tried all want a subscription fee around £2 a month. However, it does have some minor drawbacks yes, in that you need data or WiFi to play (pretty sure never tested but it's yt), you need to keep your phone on the whole time which you could sometimes forget to do, and you also need to press "start alarm", which you can understandably forget to do, since with the usual apple alarm simply saving an alarm keeps it ready, but here you yeah need to make sure you see the warning that tells you to keep your alarm on and the timer, simply having the alarm displayed or the main page of alarms won't activate it even if your phone is on, which can be a nuisance to remember but either write a note with the instructions or cope, and after a while you should remember the process. But yeah, a lengthy review but overall as the title states, it is good and I do indeed recommend.
