Turn your iPhone or iPad into bubble wrap that never runs out. Popwrap is an offline ASMR fidget toy inspired by transparent plastic bubble wrap. Press and hold for a deliberate snap, sweep across a row for a fast chain of pops, or choose Infinite mode to start a fresh sheet automatically whenever you finish. THREE WAYS TO POP • Press — hold each bubble through its visual deformation and tactile release • Sweep — glide across multiple bubbles with an optional highlight trail • Infinite — finish one sheet and continue automatically on the next MAKE EVERY SHEET YOURS • Choose bubble size with visual previews, from 2 to 11 columns • Build momentum as faster pops intensify sound, particles, and haptics • Pair transparent-plastic visuals with crisp sound and synchronized feedback • Mute sound, replace a sheet, and see this sheet’s and today’s pop counts FREE CLASSIC, OPTIONAL MATERIALS The classic transparent material is free. Wood and metal are optional one-time purchases, available individually or together. Try two bubbles in all three modes before buying. After buying one material, the other is available separately; there is no top-up offer. Play works offline. Prices, purchases and restores need an internet connection and are handled by Apple. No app account is required. Popwrap has no ads, subscriptions, analytics or tracking; settings and play statistics stay on your device. For the best tactile experience, use Popwrap on an iPhone that supports Core Haptics. On iPads without haptic hardware, the full visual and audio experience remains available. Haptic feedback is not reproduced by the iOS Simulator.
