Both apps tackle motion sickness without drugs, but from opposite angles. Carsick.App uses visual cues requiring you to watch your screen — which is often what causes motion sickness in the first place. Stillwave's 60-second sound pre-treatment lets you put your phone away and enjoy the ride. Plus, it's $0.99 once versus an ongoing subscription.
Stillwave was directly tested in real vehicle conditions. Carsick.App uses visual cues that require you to look at your screen. If you want to look out the window or chat with passengers, Stillwave is the better choice.
Stillwave is a one-time $0.99 purchase. Carsick.App uses a subscription model at $2.99/month or $14.99/year. Over a year, Stillwave saves you $14+.
No. Any earbuds work. We recommend noise-cancelling earbuds (like AirPods Pro) for best results, but regular earbuds are fine.
60 seconds of sound, up to 2 hours of relief. No side effects.
