Which iPhone models and iOS versions are supported?

VocabPin supports any iPhone running iOS 17 to the latest iOS 27. Both Lock Screen widgets (Accessory Rectangular) and Home Screen widgets (System Small and System Medium) are fully supported across all devices, including Always-On displays on iPhone 14 Pro, 15 Pro, 16 Pro, and newer models.

Does the widget drain my iPhone battery?

Not at all. VocabPin is built purely using Apple's native WidgetKit Timeline API. Instead of running background network tasks or GPS, the app pre-calculates lightweight timeline slices locally. It uses 0% background battery.

Can I choose my proficiency level and languages?

Yes! VocabPin supports 16 global languages (Spanish, French, German, Italian, Japanese, Korean, Chinese, and more). You can choose any native language and target language combination (240+ mutual pairs), and select your exact proficiency level (from CEFR A1 beginner up to C2 mastery, JLPT N5–N1, or HSK 1–6).

How often do the words rotate on my screen?

You are in full control. In the app settings, you can choose a refresh interval of every 10 minutes, 1 hour, 2 hours, 4 hours, 8 hours, 12 hours, or once every 24 hours (classic Word of the Day).

Can I hear native audio pronunciation?

Yes! Whenever you tap the widget on your screen, it deep-links directly into VocabPin's word detail card, where you can listen to crystal-clear native pronunciation and read real-world contextual example sentences.

Cognitive Micro-Exposure

The power of 80 daily micro-exposures.

Traditional learning forces you to cram words for 30 minutes, 90% of which decay within 48 hours according to the Ebbinghaus Forgetting Curve. VocabPin re-architects the cadence:

Frequently Asked Questions

Everything you need to know about VocabPin widgets and passive learning.

VocabPin places curated foreign language vocabulary directly on your iPhone Lock Screen and Home Screen using native iOS WidgetKit. Since the average smartphone user glances at their phone 80+ times a day, your brain repeatedly encounters the word, reading, and meaning throughout the day. This creates cognitive priming and spaced retrieval without the willpower required to open a study app.
