The least-friction calorie tracker on iOS.
No barcodes. No 12-screen onboarding. No subscription paywall before you can even open the app. Voidpen earns its place.
Snap a photo, get calories
Point your camera at a meal. Voidpen reads it and logs calories and macros in seconds — no barcode, no menu hunting.
Talk it through
Press and speak. “Two eggs and a piece of toast.” Done. Voice logging that actually keeps up with you.
Coach in your pocket
Ask your AI nutritionist anything — “What should I eat for dinner?”, “Am I on track?” Personal, fast, judgment-free.
HealthKit, both ways
Two-way sync for weight, height, and body composition. Your data stays in one place — yours.
Built for your day
Widgets, fast logging, photo memories of past meals. Built to fit a real life, not just a sticker chart.
Private by default
No accounts. No tracking. An anonymous install ID is all we need. Delete anytime.

Common questions
Does Voidpen need an account?+
No. Voidpen uses an anonymous install ID — no email, no password, nothing to remember. Your data is tied to your install.
How accurate is the photo scan?+
Voidpen uses state-of-the-art vision models. Estimates are typically within ±15% — close enough to spot trends. Always double-check labels if you need exact numbers.
Does it work offline?+
Basic logging works offline. AI features (photo, voice, Coach) need an internet connection because they run in the cloud.
How do I cancel my subscription?+
On iPhone: Settings → Apple ID → Subscriptions → Voidpen → Cancel. Your access continues until the end of the current billing period.
How do I delete my data?+
