Cash Book vs PocketGuard (2026): Linked Banks vs No Account

A warning about this page before anything else. PocketGuard's website and help center refused every request we made on 12 September 2026. So every PocketGuard fact below comes from its US App Store listing, release notes, purchase list, privacy label and recent App Store reviews. Where the listing does not settle something, this page says not stated and leaves it there. The last section is longer than usual as a result.

With that said. PocketGuard connects to US and Canadian bank accounts, identifies bills and subscriptions on its own, and shows a safe-to-spend figure it calls Leftover. PocketGuard Plus is $12.99 a month or $74.99 a year. Cash Book never touches a bank: say what you spent, snap a receipt, or let an Apple Pay tap log itself, and the record stays on your iPhone for $39.99 a year or $19.99 once. Bank in the US or Canada and want your spending read for you? PocketGuard. Want to log in a sentence, in any currency, with no account and no bank login handed over? Cash Book.

Feature table

Three PocketGuard features have no Cash Book counterpart at all, so the table does not pretend to score them: bill negotiation, the debt payoff plan, and automatic subscription detection. Cash Book's answer to recurring costs is manual and unglamorous, a guide to tracking subscriptions and a subscription cost calculator. Its reporting lives in Insights: stat tiles, changes by tag, six months of income against expenses.

Note the registration row too. Recent reviews describe signing up with a phone number. Cash Book asks for nothing, which is a smaller thing than bank sync and a bigger thing than it sounds.

Pricing side by side

PocketGuard's prices come from its App Store description and purchase list, in US dollars, on 12 September 2026; its website pricing page could not be read.

Two details from the small print. The description says prices may vary outside the United States and are subject to change without notice. And the purchase list holds eight items, one of them a $34.99 PocketGuard Plus entry with no period attached, none of which the description explains. This page quotes only the $12.99 and $74.99 that PocketGuard states in words, because the rest is guesswork and guesswork does not belong on a pricing table.

How each one handles your data

The privacy policy could not be fetched, so this section leans on the developer-declared App Store privacy label and the security claims in the description. That is a thinner basis than we would like, and it is worth saying so.

The label lists financial info, contact info, user content, identifiers, usage data and diagnostics under data used to track you. Under data linked to you it names third-party advertising, using user ID, device ID, usage data and advertising data, plus the developer's own advertising or marketing, and analytics that include payment info, credit info, physical address, email address, name and phone number. That is a long list for a budgeting app, and it is the developer's own declaration rather than anyone's accusation. The description promises 256-bit SSL encryption and app access protected by PIN codes and biometrics such as Touch ID and Face ID. Where the data lives, and whether the app shows ads, is not stated anywhere we could reach.

Cash Book's privacy model is shorter because there is less of it. Transactions live on your iPhone and, if you switch it on, in your own iCloud account, encrypted so that only you can access it. No account, no server holding your history. Voice clips and receipt photos go to an AI model through the studio's relay and are not kept after the response. Usage analytics count screens and outcomes in aggregate, never transaction contents. Face ID or Touch ID locks the app. No ads, no data selling, no contacts or location access. The full privacy policy is on this site.

Who should pick PocketGuard

PocketGuard is built for someone who banks in the United States or Canada and wants transactions, bills and subscriptions identified without typing a thing, and it does a category of work Cash Book does not attempt. Leftover is a genuinely good idea: one safe-to-spend number after bills and goals have been taken out. Carry credit or loan balances and it will build a payoff plan from them. The bill organizer will even offer to negotiate better rates with your providers. Recent reviews describe it as simple and beginner-friendly, which for a bank-connected app is harder than it sounds.

Who should pick Cash Book

• You would rather say what you spent than link a bank, in your own language; the voice logging guide shows what a day's entry sounds like.
• You live outside the US and Canada, pay in cash, or move between currencies; Cash Book handles 128.
• You want Apple Pay taps logged automatically without handing anyone your bank login.
• You want budgets that say how much is left under one big number, with tags and categories you define yourself.
• You want your history on your phone, exportable to CSV or Excel.
• You would rather pay $39.99 a year or $19.99 once than $74.99 a year or $12.99 a month.

What we could not verify

More than usual, because pocketguard.com and help.pocketguard.com returned a region block or an error on every request. The free-plan limits, if a free plan exists at all, are unverified; recent reviews describe both a paywall with no way around it and the best free budgeting app on the store, and this page does not pick a side. The lifetime price is unverified: reviews mention a single lifetime payment, but no such purchase appears in the App Store list. The privacy policy could not be read, so data location, retention, sharing and ads policy come only from the App Store label. Manual or cash tracking, receipt scanning, voice entry, CSV export, multi-currency, widgets, Apple Watch, an Android app and an official web app are not stated, and the purchase list beyond $12.99 a month and $74.99 a year is unexplained. Reddit was not consulted.
