Never wonder if you took it. Stick any cheap NFC tag on a vitamin or supplement bottle, tap with your iPhone, and the dose is logged - instantly. Even from the lock screen. No typing. No "did you take it?" prompt. A tap is the log. HOW IT WORKS 1. Stick an NTAG213 or NTAG215 sticker on the bottle. Any generic NFC tag works — nothing is locked to a branded kit. 2. Link it once in LidTap (name the supplement, scan, done). 3. Hold the top of your iPhone to the bottle whenever you take it. 4. The time is recorded. That’s the whole app. WHAT YOU GET • Instant NFC logging, including background and lock-screen taps • Optional reminders at the hour and days you choose, per supplement - no marketing, no daily noise • A Today widget that shows what’s still left to take • A history you can trust, with charts by week, month, and year • Manual "Taken now" and "Taken at…" when the phone isn’t in your hand • Undo, edit, or delete any dose • Several tags per supplement for a home bottle, a spare, or travel • Everything stays on this iPhone - no account, no cloud, nothing uploaded FREE TO START Add up to 3 supplements, 2 tags each, and keep the last 7 doses, plus weekly statistics. LIDTAP PREMIUM Unlock unlimited supplements and tags, the full dose history, monthly and yearly charts, and CSV export. Cancel anytime. LidTap is a personal logging tool.

Verdict
The clearest difference is price: LidTap at Free against Keto Scanner's $2.99. Keto Scanner's advantage is in-app purchases (none vs 1) and update cadence (every 4 days vs every 5 weeks). On ads and device support there is nothing between them.
