Count Sunscreen Reapplications Across a Day Outdoors
A long outdoor day needs more reapplications than the label’s interval alone suggests, and each one interrupts what you were doing. Count the applications across each block and the minutes they actually cost.
1 · outdoor block | minutes outdoors | reapplication interval minutes

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the sun exposure ladder: your outdoor block | minutes outdoors | reapplication interval minutes stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Intervals restart after each application: a 90-minute interval only covers 90 minutes. After: the sun exposure ladder shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Timing arithmetic on label intervals and your own block plan. Not medical or dermatological advice; follow the instructions on the product you use, and see a pharmacist, clinician or dermatologist about skin concerns, photosensitivity or medication interactions.

Optional AI formatting, not calculation
For this sun exposure ladder, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a sun exposure ladder. Return plain rows only: outdoor block | minutes outdoors | reapplication interval minutes. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: outdoor block | minutes outdoors | reapplication interval minutes. No AI response is executed as code.
