# LidTap — Never wonder if you took it

LidTap is an iPhone app. Stick a tiny NFC tag (NTAG213 or NTAG215) on a supplement bottle. One tap with your iPhone logs the dose — instantly, privately, on this device. No typing. No “did you take it?” prompt.

## Three steps. Then it’s a reflex.

1. **Stick a tag.** Any cheap NTAG213 or NTAG215 sticker. Not a branded kit — the ones already in your drawer work. Put it on the **lid**.
2. **Link it once.** Name the supplement, hold the top of your iPhone to the bottle, and LidTap writes the link. About ten seconds.
3. **Tap to log.** Every morning, same gesture. The time is recorded — in the app, or from the lock screen. That’s the whole app.

## What LidTap gives you

- **A tap is the log.** Hold your iPhone to the bottle and the moment is recorded. Confirmation if LidTap is open; a quiet notification if it isn’t.
- **A history you can trust.** Today, this week, and the full chart. A Home Screen widget shows what’s still left to take.
- **A nudge when it counts.** Optional reminders at the hour you choose, per bottle.
- **Private by design.** No account. No iCloud copy of your log. Supplements, tags, and history stay on this iPhone.

## iPhone-only

LidTap is iPhone-only. NFC needs a real device. There is no Android, iPad, or Apple Watch app.

## Not a medical app

LidTap is a convenience logger, not a medical device, and not advice. A tap records a timestamp next to a name you typed. It does not mean the right bottle was tapped, or that anything was swallowed. Don’t rely on it for medication or an emergency.

This website does not record doses. Opening a bottle link in a browser does not log anything. The address on the tag only helps iOS open LidTap on your phone.
