October 28, 2026
New Features 1. Full iPad support: JianBox now runs natively on iPad. On 13-inch displays the tool grid lays out in four columns with centered content, and the floating bottom bar and credits panel are redesigned for large screens - with the same portrait experience as on iPhone 2. Foldable iPhone ready: layouts switch automatically between the cover and inner displays - on the unfolded inner screen the bottom bar centers itself and every tool makes full use of the space Fixes 1. More honest messaging: abandoning a rewarded ad no longer shows "Poor network - please try again later"; it now simply says the ad was closed early and no credits were earned 2. Several stability fixes Others 1. Upgraded to the latest generation of our underlying framework: smoother performance, full compatibility with the newest iOS versions, and a solid base for upcoming features 2. The 1.6 credits system is unchanged: watch ads to earn credits, spend them on tools - same rules, same history All file processing happens locally on your device and files are never uploaded. Credits only unlock in-app features, cannot be exchanged for cash, transferred or redeemed, and can only be earned by watching ads.
