Challenge
The challenge was to make outdoor tanning feel guided and repeatable without turning the product into a heavy medical tool or a noisy cartoon interface.

SunDeck
OUTDOOR TAN GUIDE
A weather-aware outdoor tanning guide that helps users plan the sun, follow the rhythm, and save each session.

Solution
I shaped SunDeck around a practical session flow: check UV and weather, choose a preset, follow a live timer, take shade breaks, and save the result as history.
Impact
SunDeck makes tanning sessions easier to pace, remember, and explain by placing weather data, timing, safety reminders, playful guide characters, and travel-style Tan Diary content inside one product system.
Lifestyle Utility
Outdoor tanning, timed carefully.
SunDeck is not just a pretty timer. It turns UV, weather, SPF setup, turn timing, shade breaks, and session history into a mobile routine with a lighter lifestyle voice.

Session Flow
A tan session becomes a step-by-step routine.
The page follows the same logic as the app: check the outdoor condition, choose a preset, run the timer, pause in shade, and save what happened.
UV Check
Read the outdoor window.
Location, UV index, temperature, weather, and available tan time decide whether the session should start now.Preset
Pick the rhythm.
Balanced Tan, Quick Bronze, Deep Outdoor, or Maintain Tone turns a casual plan into a readable routine.SPF Setup
Make prep part of the timer.
The session begins before lying down: SPF setup and waiting time are part of the guided flow.Turn
Keep exposure paced.
Turn cues and posture steps make the user follow a routine instead of guessing with a loose timer.Shade
Pause without losing context.
Shade breaks, hydration, and stop-condition reminders keep the product practical without becoming clinical.Save
Remember the session.
History keeps UV context, location, routine type, and duration so the next session has a reference point.Guide Characters
The character system softens the safety layer.
Guide characters give the app a memorable product voice while the core interface stays readable: UV data first, timing second, personality at the right moments.

Tan Diary
The app story extends into travel content.
SunDeck also runs a Tan Diary layer: fictional supporters travel, write destination-based posts, and connect weather, UV, outdoor time, and lifestyle context back to the product.

Responsible Tone
Careful, but not clinical.
The product avoids medical claims. It uses reminders, shade breaks, stop conditions, and clear disclaimers so a lifestyle app can still feel structured and responsible.
UV and temperature are treated as planning inputs, not decorative stats.
SPF setup, turns, shade, and end controls make the session repeatable.
Saved records let users compare prior sessions before going outside again.
