Price and subscription41%

25 of the 1 and 2 star reviews.

★★★★★ I wanted to buy a monthly subscription to try the app.
★★★★★ no free trial to see if it even a fit
★★★★★ they try to make it seem like you have to spend money to use it and do every possible trick to get you to accidentally hit the subscribe button and give them money.
Wrong or poor results15%

9 of the 1 and 2 star reviews.

★★★★★ Sorry but this app is completely useless....uninstalled within 10mins of downloading it.
★★★★★ The ads, fake "jackpot" offers is way tooo much
★★★★★ A trial period would be nice before i drop money on something that may be useless.
Too many ads10%

6 of the 1 and 2 star reviews.

★★★★★ years ago this was a great app but now everything is either locked behind a paywall or ads.
★★★★★ The ads, fake "jackpot" offers is way tooo much
★★★★★ Right after I finished, I was shown at least five to seven advertisements about premium deals and other stupid content.
Bugs, things not working5%

3 of the 1 and 2 star reviews.

★★★★★ App fails alot to record, start it looks fine but by morning failed to record and shows error.
★★★★★ Too many pop ups for upgrading and twice now the app stopped working in the middle of a sleep cycle.
★★★★★ also, the app is glitchy, sleep sound monitor is not included in the free version.
Limits, credits, locked features5%

3 of the 1 and 2 star reviews.

★★★★★ years ago this was a great app but now everything is either locked behind a paywall or ads.
★★★★★ Asks you 300 questions and then your credit card info when all I want is an app that records me snoring.
★★★★★ All the features you actually want are locked behind a paywall - I can only assume that all the positive reviews are because the app solicits 5-star reviews in exchange for cheap access to premium features.
