00:16.000 --> 00:20.000 · QUESTIONS

Quick answers.

Does it really work without internet?

Download is free with a generous AI allowance. If you love it, a one-time PRO upgrade unlocks unlimited use — no subscription, ever.

Can it play MKV / RMVB files on iPhone?

Yes — 100+ containers and codecs including MKV, RMVB, AVI, WMV, FLV and WebM, up to 4K/8K HDR with hardware acceleration. See supported formats.
