Callbook is a private notebook for your return visits, your Bible studies and your hours. FREE, AND OPEN Callbook is free. Create an account with an e-mail and a password, Continue with Apple, or Sign in with Google, and you are in — there is no invitation and nobody to approve you. Everything is stored encrypted on this iPhone. Your account is a name on the door, not a copy of your notes: it holds nothing you write, and there are no analytics. Sync between devices is optional, and what it uploads is sealed with a key derived from your password. PEOPLE Name, address, phone, usual day and territory. Search by any of them, and sort by territory to work through it in one go. VISITS AND STUDIES Every call keeps its own history. Mark someone as a study and it gets its own thread, so you can see at a glance who you are behind with and who is expecting you this week. HOURS Jot down your time the moment you have it — ministry, construction (LDC), Bethel or other — and the month keeps the running total for you. Credit hours count toward what you report without ever trimming ministry, and a regular pioneer's month stops at 55 the way the arrangement says it should. GOALS 600 hours a year for regular pioneers, shown as the pace the rest of the year needs rather than a flat monthly average. 30 in the month for auxiliary, 100 every month for special. Publishers get no goal and no ceiling — log hours if you want them, or don't. THE REPORT The month in exactly the shape the form asks for, ready to copy or send as a small text file. No names in it, ever. PRIVACY The database is encrypted with SQLCipher and unlocked by a passphrase only you know. That also means nobody can recover it for you — not even us. Optional sync between devices is sealed with a key derived from that passphrase, so what is stored in Google's Firebase is opaque to Google as well as to us.

CmsApp's advantage is ratings volume (23 vs 1) and iOS requirement (12.2 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.
