Elpass is a password manager and personal digital vault that you can fully control. It has an enjoyable interface and always keeps your safety in mind. Elpass isolates your vault strictly. Your data is stored on your device locally and synced with a third-party cloud service like iCloud and Dropbox. Your data will be encrypted with bank-level algorithms before being sent, making sure that nobody can access it without your master password. Security is critical, but sometimes we don't want so many troubles for insignificant items. You may set a security level for every item. A convenient level item may fill automatically without any interaction. However, a high level item requires biometric verification every time.

Verdict

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Elpass sells 2 in-app purchases, starting at $1.99 per month and SiYuan sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Elpass holds the better App Store score, 4.3 against 3.9. Both are backed by a comparable volume of ratings — 40 and 30 respectively. Written reviews complicate that: 60% of Elpass's written reviews are positive against 67% of SiYuan's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Elpass ships an update every 2 months, SiYuan every 8 days. Both last shipped on November 3, 2026.
