Voidspace is a simple, immersive app built for breathing and meditation — nothing more. The moment you open it, deep-space particle visuals surround you. As your session deepens, the animation evolves, naturally drawing your awareness inward. ■ 3 Breathing Techniques ▷ Natural Breathing (4s inhale · 6s exhale) The simplest form of diaphragmatic breathing. Perfect for everyday relaxation or winding down before sleep. ▷ Box Breathing (4 · 4 · 4 · 4) Inhale, hold, exhale, hold — in equal counts. Used by athletes and military personnel for focus and composure under pressure. ▷ 4-7-8 Breathing (inhale 4 · hold 7 · exhale 8) A deep relaxation technique that activates the parasympathetic nervous system. Ideal before bed or during moments of high stress. ■ Session Length Choose from 1, 3, or 5 minutes — or go unlimited. ■ Sound A synthesized drone shifts its filter and dynamics with each breath phase. Enable 40Hz Gamma mode to add amplitude-modulated ambient sound shown to support focus and relaxation. No headphones required. ■ History & Heatmap A calendar heatmap shows your practice at a glance. Seeing your streak is quietly motivating. ■ Privacy First No account. No analytics. No ads. Your data lives only on your device — nothing is ever sent anywhere. ■ English & Japanese The app detects your device language automatically. You can also switch manually inside the app. Your breath is always with you. Voidspace gives it a place to land.

Verdict
The clearest difference is ads: Voidspace at none against EyeFile's shown. Voidspace also leads on update cadence (every 10 days vs every 6 months). EyeFile's advantage is iOS requirement (11.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
