No method matches these answers yet. Have a look at the methods below.
Each method has trade-offs. The coloured badges show how long installs last and how risky they are.
Permanent install
iOS: 14.0 – 16.6.1; 16.7 RC (needs a computer); 17.0 (needs a computer)
TrollStore installs IPA files permanently, for free, with no certificate, but only on iOS 14.0 – 16.6.1, 16.7 RC and 17.0. Check whether your iPhone qualifies.
Certificate signing
iOS: 16.0 and later
Install KSign, import your certificate, then sign and install IPA files right on your iPhone. The most popular method in Vietnam today.
Certificate signing
iOS: 12.0 and later
ESign is a long-standing IPA signer still used on older iPhones. Import a certificate, then sign and install IPA files, plus a warning about DNS profiles.
Free certificate
iOS: 12.0 and later
GBox offers a free certificate and a personal UDID certificate, and its developer claims support up to iOS 27. Easy to use, but the free option is often revoked.
Certificate signing
iOS: 16.0 and later
Feather is an open-source, ad-free IPA signer for people who already have a personal certificate. Install Feather and sign IPA files right on your iPhone.
Official marketplace
iOS: 17.4 and later (EU only); 26.2 and later (Japan only)
AltStore PAL is an Apple-approved alternative marketplace in the EU (iOS 17.4+) and Japan. It doesn't work in Vietnam. Requirements and setup steps.
Free Apple Account
iOS: 15.0 and later (needs a computer)
SideStore signs IPA files with your own free Apple Account, which is legitimate and avoids mass revokes. The catch is a computer once and a refresh every 7 days.
