Focused work with environmental sounds! I recommend you work from home! Environmental sounds are also effective for sleeping, relaxing and learning. Multiple ambient sounds can be played back at the same time. You can even adjust the volume individually! It has been shown that you can concentrate better with environmental sounds than with silence. Music has been shown to be effective for routine work, but it has been shown to be counterproductive for overburdened brain work. The app includes a variety of environmental sounds. You can use it as a guideline for work and study with the timer function. Features Our app is particularly focused on the sounds of rain and wind, and contains a variety of variations. For example, in the case of rain, there are various sounds such as the sound of rain with an umbrella, the sound of rain in a prefab hut, and sideways rain due to strong winds. Wind can range from a gentle breeze to a wind blowing through a ravine to a typhoon. In addition to rain and wind, there are also fireworks, waves, waterfall, footsteps, etc. Simultaneous playback and background playback Multiple environments can be combined for simultaneous playback. You can adjust the volume individually and play in the background, of course. Timer function A timer function with 15-minute increments is implemented. You can use it as a guideline for working and studying, and you can set it to stop playing at a certain time when you sleep. Favorites function Add your favorite ambient sounds to your favorites. In no time, you'll have access to your regular sounds! So use Aphria to help you work, learn and sleep.

Time your sauna sessions from your wrist and see your heart rate zone as you go. Sauna Flow is a sauna timer for Apple Watch that keeps a clear record of every session on your iPhone. Set a target time, start on your Apple Watch, and stay focused on the heat. Afterwards, your iPhone shows how the session went and how your routine is building week by week. ■ Round mode • Plan 1 to 5 rounds of sauna, cool-down and rest on your Apple Watch. • Each sauna phase starts when you tap. Cool-down and rest move on automatically, with a haptic at each change. • Your iPhone shows a breakdown for every round. ■ Live heart rate on your Apple Watch • See your current heart rate and zone during the session, with optional alerts when your zone changes. • Zones are based on a max heart rate you choose: the default, an age-based estimate, or your own value. ■ Your sauna routine • A session calendar that marks the days you went. • Current and longest streak, plus a weekly goal you set (1 to 14 sessions). • Optional reminders on the weekdays and at the time you pick. They stay off unless you turn them on. • Session details: duration, average and highest heart rate, time in each zone, plus effort and stability scores for single sessions. • Export your sessions to CSV or share a session card. ■ On your watch face • Add the Sauna Flow complication to open the app in one tap. ■ Sessions you can count on • Each session stays on your Apple Watch until your iPhone confirms it is saved, and is resent automatically. • If the app closes mid-session, the session is recovered and saved as interrupted. • If your Apple Watch gets too hot, it warns you. If it overheats, the session is saved and ended. ■ Apple Health • Sessions and heart rate data are saved to Apple Health. ■ Your language • Korean, English, German, Finnish, Japanese, Dutch and Russian. Choose in the app's settings; your Apple Watch follows. ■ Premium • Your 3 most recent sessions are always available. Sauna Flow Premium, an in-app purchase, unlocks your full session history and full export. ■ What you need • Apple Watch with watchOS 10 or later to record sessions. ■ Please note • Sauna Flow is not a medical device and does not provide medical advice. Heart rate zones are informational estimates, not medical measurements. • If you have a cardiovascular condition or other health concerns, consult your doctor before using a sauna. • Stay hydrated and avoid overheating. Stop your session immediately if you feel unwell. • Apple Watch and iPhone are not designed for extreme heat. Do not expose your device to sauna temperatures beyond its operating range (Apple Watch: 0–35°C / 32–95°F); keep it somewhere safe. Protecting your device is your responsibility.

Verdict
The clearest difference is in-app purchases: Applia at none against Sauna Flow's 1. Applia also leads on iOS requirement (10.0 vs 17.6). On price, ads and device support there is nothing between them.
