What is CalculatorQueen A1C Calculator?
A free, transparent A1C and estimated average glucose converter. Enter an NGSP A1C percentage to estimate eAG in mg/dL and mmol/L, or start with eAG and translate the same ADAG regression in reverse. The page keeps units and equations visible, includes a quick comparison table, and clearly explains that the result is a population-based translation rather than a diagnosis or substitute for laboratory testing, glucose monitoring, or professional care.
What problem it solves
Laboratory A1C uses percent while glucose reports may use mg/dL or mmol/L. The calculator translates those units without treating a single glucose reading as an A1C result.

What is Nitavera?
Nitavera is a browser-based skin analyzer and skincare product checker. It estimates redness, spots, oil and texture from a face photo processed on your own device; the face photo is not uploaded. Its results are cosmetic guidance, not a diagnosis or a medical treatment plan. Lighting, camera quality and other conditions can change the estimates.
You can scan your skin, check products you already own, and compare ingredient lists for potential routine conflicts. My Shelf flags combinations that may need more care and offers general AM/PM placement ideas. It does not tell you to change a prescription. If a skin concern is painful, scarring or persistent, see a licensed clinician.
A verified Google signup currently unlocks Pro free, with no card, checkout or time limit. Pro includes guided multi-angle scanning, unlimited scans and product checks, routine reminders and the Nitavera Assistant. Photos and scan history stay in the browser where you use them; signing in does not sync those photos to another device. The assistant sends your typed questions and a short skin summary to its AI provider, but not your photo. Nitavera does not take brand sponsorships or affiliate payouts for product rankings.
What problem it solves
Skincare advice often starts with generic routines or a product ranking that ignores what someone already owns. Nitavera lets people check their own skin and ingredient lists, see potential routine conflicts, and get a simple starting point without uploading a face photo to a server. It is cosmetic guidance, not a diagnosis.
