Tanning

A tanning plan built around your skin and today's UV

A useful tanning plan doesn't start with a generic number of minutes. It starts with your Fitzpatrick skin type, the current UV Index at your location, the SPF you're wearing and how you structure the session — then loops in rest and progress. T&T turns those inputs into a personalized tanning-time estimate you can actually plan around.

The short answer

What is a tanning plan?

A tanning plan is a structured approach to outdoor tanning sessions that accounts for personal context and changing conditions — instead of picking an exposure time from a generic chart. A useful plan considers your Fitzpatrick skin type, the current UV Index at your location, the SPF you're wearing, how you structure each session (front / back, breaks, reapplication), how you rest between sessions, and how you review what actually happened.

It isn't a medical protocol. It doesn't promise a specific tan shade by a specific date. It's a planning tool — a way to make more informed decisions about time in the sun.

The problem with fixed schedules

Why generic tanning schedules fall short

A day-by-day chart of “Day 1: X minutes, Day 2: Y minutes, Day 3: Z minutes” looks tidy, but it can't account for the things that actually decide UV exposure on the day:

  • UV isn't a fixed daily number — it climbs through the morning, peaks around solar noon, drops in the afternoon, and varies with cloud cover, altitude and season.
  • Two people at the same UV can have very different UV response — Fitzpatrick skin type is one of the main reasons.
  • The SPF a person is actually wearing (and how often they reapply it) changes the picture again.
  • Session structure (front / back, breaks, reapplication) affects how the same clock time translates into real UV exposure.

A useful plan replaces the fixed schedule with the inputs that change between sessions — and gives you a way to review what actually happened.

Input 1

Start with your skin type

The Fitzpatrick scale groups skin into six phototypes (I–VI) based on how skin tends to burn and tan under UV. Two people under identical UV can have very different UV response, so the same plan template needs different underlying inputs per person.

T&T uses your Fitzpatrick type as one input into every personalized session estimate. Set it manually, or use the live camera preview to compare your inner wrist against the six reference swatches (no photo captured, saved or uploaded). For a full guide to the six phototypes and the scale's limitations, see the Fitzpatrick skin types guide, and for how skin type affects tanning specifically, see the dedicated guide.

Type I exception. Fitzpatrick Type I users don't receive a tanning routine in T&T — the app provides a Sun Safety Plan instead. The Fitzpatrick phototyping literature characterises Type I skin as tending to burn readily and rarely tan under UV.

Input 2

Check today's UV before planning the session

The UV Index is a standardised international measure of the intensity of sunburn-producing UV. It isn't a fixed daily number — it climbs through the morning, peaks around solar noon, drops in the afternoon, and varies with cloud cover, altitude and season. A plan that ignores it is guessing.

T&T shows the current/live UV Index for your location on the main screen. For a deeper look at what today's UV Index means in a tanning context, see the UV index for tanning guide; for a UV-first product view, see the UV Index app landing.

Input 3

Add the SPF you actually use

SPF slows how fast your skin accumulates a UV dose. It isn't a simple time multiplier — the U.S. FDA Center for Drug Evaluation and Research states explicitly that SPF is not directly related to time of solar exposure. Sunscreen doesn't make UV exposure risk-free, and its protection can decrease as it wears or washes off. Real-world protection depends on how much sunscreen was actually applied and on following the reapplication directions on the product label.

T&T uses the SPF you're actually wearing as one input into the personalized tanning-time estimate — not a countdown by itself, not a longer-in-the-sun licence. For a deeper look at what SPF actually does in a tanning session, see the SPF for tanning guide.

In the app

Turn those inputs into a personalized session estimate

T&T combines the three inputs — your Fitzpatrick skin type, the SPF you're wearing and the current/live UV Index for your location — into a personalized tanning-time estimate. That estimate feeds into a session timer with front-and-back tracking and a flip reminder.

The estimate is a planning tool, not a medical prediction, and it isn't a guarantee against sunburn. Speak to a dermatologist if you have specific skin concerns. For the underlying question — how long should I tan? — the dedicated guide walks through each factor in detail.

One session vs the broader plan

From one session to a broader plan

A personalized session estimate is the first step. A plan is what wraps around it: how sessions repeat, how you rest between them, and how you review what actually happened so the next session is informed by the last.

T&T's free tier handles the per-session part — the personalized tanning-time estimate, session logging (last 3 sessions free), UV forecast for today and tomorrow, and sunscreen-reapplication reminders during a session. Premium expands the broader plan side: a multi-week tanning routine, a custom plan builder, rest-day recommendations, unlimited session history, and the full 10-day UV forecast.

The in-session layer

Guided tanning sessions

Inside the plan, T&T's guided-session workflow handles the step-by-step flow during an individual session — timed rounds, flip reminders, breaks, and sunscreen-reapplication prompts. Guided sessions are free with a 3-uses-per-rolling-7-days allowance; Premium unlocks unlimited use.

The routine layer (Premium)

Multi-week routine and custom plan builder

T&T Premium expands planning beyond individual sessions with a multi-week tanning routine, a custom plan builder, and rest-day recommendations. These are app planning guidance — not a medical protocol, and not a guarantee of a specific tan shade by a specific date.

For a deeper look at the routine layer specifically — how repeated sessions are structured — see the tanning routine guide.

Between sessions

Rest days matter

Time between sessions is a real part of a plan. The right cadence depends on personal skin response, the UV conditions of previous sessions, and how a previous session actually went. There isn't one universal number that applies to everyone.

Public-health guidance from the World Health Organization treats solar UV as a known skin-cancer risk factor and recommends limiting exposure rather than maximising it. On Premium, T&T can provide rest-day recommendations as part of its multi-week routine — these are app planning guidance, not a medical protocol or a substitute for professional dermatological advice.

The plan feedback loop

Track what actually happened

A plan without feedback is just a wish. T&T logs each session (UV, duration, SPF) so you can look back at what you actually did and adjust the next session accordingly.

    Review

Free users see the last 3 sessions; Premium unlocks unlimited history. Base tan-progress swatches are free; the photo diary is 3 photos free lifetime, with expanded access on Premium. Cloud sync (Premium) keeps history across devices. Visible tan development also has its own tanning timeline — separate from session length.

Plan ahead

UV forecast and planning ahead

T&T includes a 10-day UV forecast for your location so you can see how UV conditions are expected to change and plan sessions around the days you actually want. Free users can see today and tomorrow; Premium unlocks the full 10-day forecast.

A forecast is a prediction, not a measurement. Actual UV on the day can differ — cloud, weather changes and other factors move the real reading — so the forecast is best used for planning windows and comparing upcoming days, with the live UV Index handling the moment you're actually outside.

Different layers, different jobs

Tanning plan vs routine vs timer vs guided session

These are four related but distinct concepts inside T&T. The plan is the top layer; each layer beneath handles a more specific job.

  • Tanning plan

    The broader approach — how skin type, current UV, SPF, session structure, rest and progress fit together for you. That's what this page is about.

  • Tanning routine

    The repeated-session structure over time — a routine you can re-run. See the tanning routine guide for the routine layer specifically.

  • Guided session

    The step-by-step flow during an individual session — timed rounds, flip reminders, breaks, sunscreen-reapplication prompts. Free with a 3-per-rolling-7-days allowance; unlimited on Premium.

  • Tanning timer

    The active-session timing tool. See the tanning timer guide for what the timer does inside the plan / routine / guided-session stack.

Common questions

Tanning plan — FAQ

What is a tanning plan?

A tanning plan is a structured approach to outdoor tanning sessions that accounts for changing conditions and personal context — instead of picking a session length from a generic chart. A useful plan considers your Fitzpatrick skin type, the current UV Index at your location, the SPF you're wearing, how you structure each session (front / back, breaks, reapplication), how you rest between sessions, and how you review what actually happened. It's a planning tool, not a medical protocol or a guarantee against sunburn.

How do I make a tanning plan?

Start with your Fitzpatrick skin type; check the current UV Index at your location; set the SPF you're wearing; decide on session structure (front / back, breaks, reapplication); factor in rest between sessions; and review what happened afterwards so the next session is informed by the last. T&T brings those inputs into one workflow: skin type + selected SPF + current/live UV → a personalized tanning-time estimate that feeds into a session timer, with session logging and — on Premium — a multi-week routine and a custom plan builder.

Should a tanning plan change with the UV Index?

Yes. UV isn't a fixed daily number — it climbs through the morning, peaks around solar noon and drops in the afternoon, and varies with cloud, altitude and season. A useful plan treats the current UV Index as an input for every session rather than assuming yesterday's timings still apply. For a deeper look at UV in a tanning context, see the UV index for tanning guide.

Does skin type change a tanning plan?

Yes. The Fitzpatrick scale (I–VI) classifies skin by how it tends to respond to UV, and two people under identical UV can have very different UV response — so the same plan template needs different underlying inputs per person. T&T uses your Fitzpatrick type as one input into every personalized session estimate. Note: Fitzpatrick Type I doesn't receive a tanning routine in T&T; Type I users receive a Sun Safety Plan instead.

Does SPF affect a tanning plan?

Yes. SPF slows how fast your skin accumulates a UV dose, but it isn't a simple time multiplier — the U.S. FDA states explicitly that SPF is not directly related to time of solar exposure. T&T uses the SPF you're actually wearing as one input in the personalized tanning-time estimate. See the SPF for tanning guide for a deeper look.

How long should a tanning session be?

There isn't one correct number of minutes that works for everyone. Session length depends on the current UV Index at your location, your Fitzpatrick skin type and the SPF you're wearing. T&T combines those three inputs into a personalized tanning-time estimate — a planning tool, not a guarantee against sunburn. See the how long should I tan? guide for a full walkthrough of the three factors.

How many days should I rest between tanning sessions?

There is no universal rest-day count that applies to everyone — the right cadence depends on personal skin response, UV conditions and how a previous session went. Public-health guidance from the WHO treats solar UV as a known skin-cancer risk factor and recommends limiting exposure rather than maximising it. On Premium, T&T can provide rest-day recommendations as part of a multi-week tanning routine; these are app planning guidance, not a medical protocol. Speak to a dermatologist if you have specific skin concerns.

Does T&T create a personalized tanning plan?

T&T uses your Fitzpatrick skin type, the SPF you're wearing and the current/live UV Index for your location to produce a personalized tanning-time estimate for each session — that's the personalization the free tier delivers. On Premium, T&T expands planning with a multi-week tanning routine, a custom plan builder, and rest-day recommendations. It doesn't produce a fixed day-by-day exposure schedule for you to follow blindly, and no plan makes tanning risk-free.

Can Fitzpatrick Type I use a tanning plan?

Fitzpatrick Type I users don't receive a tanning routine in T&T — the app provides a Sun Safety Plan instead. Type I users can still see the live UV Index, use sunscreen-reapplication reminders and set up sun-protection guidance in the free tier.

What is the difference between a tanning plan and a tanning routine?

A tanning plan is the broader approach — how skin type, current UV, SPF, session structure, rest and progress fit together for you. A tanning routine is the repeated-session structure inside the plan — a routine you can re-run over time. In T&T, the plan is expressed through the personalized session estimate, session logging and (on Premium) the custom plan builder; the tanning routine feature adds a Premium multi-week routine on top. See the tanning routine guide for the routine layer specifically.
