Cycling through all six. Tap any point to stop.
Measured on six things
Cash Book is an iPhone AI expense tracker you talk to: say what you spent, snap a receipt, or let every Apple Pay tap log itself.
HTTPS enforced with X-Content-Type-Options and Referrer-Policy, but no HSTS, CSP, frame protection or DMARC (5/12 probe points). Privacy model is genuinely strong: no account, no bank link, on-device data, disclosed AI processing. No audits published.
Cash Book is an expense tracker for iPhone built on one idea: logging so fast you actually keep doing it. Say "12 euros lunch" and AI turns your voice into a transaction with amount, merchant, tag and date. Snap a receipt or a screenshot and every line is read for you. Set up one Apple Shortcuts automation and every Apple Pay tap logs itself. Or use the keypad: three taps. Your money is then organised the way you think: tags grouped into categories, accounts for cash, cards and savings with one net-worth number, and monthly or weekly budgets that show what is left. Insights show where the money went, what changed against last month, and six months of income against expenses. There is no account and no sign-up, and Cash Book never connects to your bank. Data stays on your iPhone, with optional encrypted iCloud sync to your own Apple account. 128 currencies, 26 languages, Face ID lock, CSV and Excel export.

Written by AI from measured evidence, scored out of 100.
Cash Book is an iPhone expense tracker built around one honest thesis: logging has to be faster than forgetting. Voice entry, receipt scanning and Apple Pay via Shortcuts deliver three genuinely different routes to a logged transaction, and the app UI — judged from its store screenshots — is calm, consistent and clearly designed by someone tired of dashboards. The privacy model is the real differentiator: no account, no bank connection, on-device data, with the AI processing asterisk disclosed rather than buried. Where it stumbles is hardening and reach — 5/12 security header points, no published audits, a contrast failure, and an iPhone-only footprint. The pricing is refreshingly blunt: 7 days free, then $39.99/year or $19.99 once, no hidden free tier. For privacy-first iPhone users who hate bank linking, it's a credible pick; for everyone else, it's a deliberate non-fit.
No sign-up, three logging paths (voice, receipt scan, Apple Pay via Shortcuts), 7-day full trial, and 8 how-to guides. The Apple Pay setup is self-described as 'fiddly once' — real friction, but honestly disclosed.
Judging the app UI from 8 store screenshots: coral accent, card-based Home with a big balance number, emoji tag chips and clean budget bars. Consistent, modern, and the site mirrors the same palette. Polished for an indie iPhone tracker.
Lighthouse mobile 93/100 with CLS 0 and TBT 0ms; desktop a clean 100/100. LCP 2.7s on mobile is the one soft spot, just over the 2.5s 'good' line. Fast, stable marketing site with no reported lag.
HTTPS enforced with X-Content-Type-Options and Referrer-Policy, but no HSTS, CSP, frame protection or DMARC (5/12 probe points). Privacy model is genuinely strong: no account, no bank link, on-device data, disclosed AI processing. No audits published.
Lighthouse a11y 96/100 with one failing audit: insufficient color contrast. 26 languages across app and site is strong reach. No WCAG statement published, and iPhone-only limits platform coverage. Solid but not audited.
A real, specific wedge: no bank link, no account, on-device data, with voice and Apple Pay logging. It deliberately excludes Android, shared budgets and bank feeds — a narrow but defensible privacy-first iPhone niche.
Judging the app itself, not the landing page: the 8 App Store screenshots show a calm, coral-accented iPhone UI — a big balance number on Home, emoji tag chips, thin budget bars that only turn red when you're over. It looks like a tracker designed by someone who actually hates trackers. Usability follows the same philosophy: no sign-up, a 7-day fully unlocked trial, and three logging routes — voice ('12 euros lunch at Beshamel'), receipt or screenshot scanning, and Apple Pay via a Shortcuts automation. That last one is the catch: the site itself calls the setup 'fiddly once', and it is a genuine onboarding tax on the feature you lead with. The 8-article guides hub does real work covering voice logging, receipt scanning, cash accounts and subscription audits, which is more documentation than most indie trackers bother with.
Speed is a genuine strength. Lighthouse mobile performance lands at 93/100 with CLS 0 and TBT 0ms — a stable, non-blocking site — and desktop is a clean 100/100. The only soft metric is mobile LCP at 2.7s, just past the 2.5s 'good' threshold, likely hero-image weight. Security is a split verdict. The privacy architecture is unusually honest: no account, no bank connection, transactions on-device with optional iCloud sync, and a plain-language admission that voice clips and receipt photos do leave the phone for AI processing and are 'not kept afterwards'. But the HTTP probe returns only 5/12 checklist points — HTTPS is enforced with X-Content-Type-Options and Referrer-Policy, yet HSTS, CSP, frame protection, Permissions-Policy and DMARC are all missing. No SOC 2, ISO or pen-test is published. Strong privacy story, thin hardening.
Accessibility scores 96/100 on Lighthouse with a single failing audit: insufficient background/foreground color contrast — the predictable cost of a coral accent on white. Against that, the app and site ship in 26 languages, which is real reach for an indie product. What's missing is a published WCAG conformance statement, and the iPhone-only scope means Android users are simply out. Growth is a judgement on the idea, not the traction: Cash Book names a specific, defensible wedge — privacy-conscious iPhone users and freelancers who refuse bank linking — and backs it with voice, receipt and Apple Pay logging that Money Manager doesn't offer. The ceiling is self-imposed: the site explicitly disclaims bank feeds, shared household budgets and Android, so it wins a narrow niche rather than the mass market Expensify and Spendee chase. That's a coherent bet, not a scalable one.
Conclusion
Cash Book knows exactly who it's for and says so out loud — if you want bank feeds, shared budgets or Android, the homepage tells you to leave. That kind of honesty is rare and it earns real goodwill. The question is whether the execution behind the promise holds up: the logging is fast, the privacy architecture is sound, and the guides show a maker who understands the problem. But the security headers are half-finished, the accessibility contrast fails, and the Apple Pay setup asks users to spelunk through Shortcuts. None of these are fatal. All of them are fixable in a weekend. For an app whose entire pitch is 'effortless', the rough edges are the thing standing between it and the users it's clearly built for.
