Sunscreen fades quietly while you enjoy the day. Sunly times your reapply reminders to the sunscreen you used and the live UV index, and warns you when the UV climbs too high, so you stay covered the whole time you are outside.
Free to download for iPhone and Android.
Your reapply reminder is based on your sunscreen strength and the live UV load, not a fixed two-hour buzzer that ignores conditions.
A clear heads-up the moment the index crosses your threshold, so you can add cover or step into the shade before you burn.
Start a session, put your phone down, and let the reminders find you. No clock-watching and no quietly burning while you relax.
Set the SPF you applied. Sunly uses it, with the live UV, to work out how long that layer will really protect you.
When you head outside, start a session so Sunly tracks your real exposure instead of guessing from a generic timer.
When the layer is fading, Sunly nudges you to reapply, and reminds you again after swimming or toweling off.
If the UV spikes past your threshold, Sunly tells you to cover up or seek shade, even between reapplications.
