VoiceZero turns every meeting into organised, searchable notes — automatically. Hit record. VoiceZero captures everything said and delivers a clean summary the moment you stop: a TL;DR, key decisions, and every action item — ready to share before you've left the room. AI features require Pro; recording and transcription are free. ONE-TAP RECORDING — FREE No setup. No bots joining your call. No calendar integrations to configure. Press record, have your meeting, get your transcript. AI SUMMARY — PRO Every recording produces a TL;DR, key decisions, and action items with owners — generated from what was actually said, not a template. Works on any iPhone or iPad: uses Apple Intelligence where available, or download Gemma directly in VoiceZero for the same AI features on any device. SEARCHABLE TRANSCRIPT — PRO Every word spoken is transcribed and indexed. Search across all your recordings to find any moment, any decision, any name. PRIVATE. ON-DEVICE. Transcription runs entirely on your device using Apple's built-in speech recognition, or switch to WhisperKit for higher accuracy (downloadable in Settings). Your audio never leaves your iPhone or iPad. No account required. ZERO SUBSCRIPTIONS Record unlimited meetings for free. Unlock AI summaries, action items, and full transcript search with a one-time Pro purchase — no subscription, ever. ZERO ANALYTICS VoiceZero collects no usage data, no crash reports, no telemetry. Nothing about how you use the app is ever shared with anyone. ZERO SERVERS There is no VoiceZero cloud. Your recordings live on your device and nowhere else.

Verdict
The clearest difference is in-app purchases: Kawaii Calc at none against VoiceZero's 1. Kawaii Calc also leads on iOS requirement (13.0 vs 26.0). VoiceZero's advantage is update cadence (every 6 days vs every 27 months). On price, ads and device support there is nothing between them.
