PREMIUM β PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. How strong is your password, really? Type or paste it and get the honest answer in one second: a real entropy score, the time a cracking rig needs to break it, and the exact patterns that give it away. Most strength checkers grade length and character variety β the same naive math that calls "Password123!" a 79-bit fortress while a GPU rig finds it in under a second. PasswordStr instead decomposes your password the way a real cracker does: dictionary words hiding behind letter-for-symbol swaps, keyboard walks, sequential runs, repeats, and years all get priced at what they actually cost an attacker. Where a shortcut exists, the engine assumes the attacker takes it β so the verdict is a floor, never flattery. WHAT YOU GET β’ A 0β100 strength score calibrated to real attacks β "P@ssw0rd2024" looks complex but scores Weak, and you see exactly why β’ Time to crack under three explicit attackers: a GPU rig at 10 billion guesses per second, slow bcrypt hashing, and a rate-limited login page β’ The attacker's view β your password split into the exact spans a cracking rule matches, each priced in bits: "'qwerty' walks adjacent keys", "'1998' looks like a year β only ~136 are ever tried" β’ Honest entropy in bits: log2 of the guesses actually needed after discounting predictable patterns, not a flattering length-times-charset figure β’ Fixes ranked by payoff, each quantified β "replace 'monkey' with unrelated characters: +24 bits", "grow to 16 characters: +26 bits" β’ A generator built on the system cryptographic RNG β 8 to 64 characters, your choice of character classes, look-alike filtering, and a copy button that clears the clipboard after 60 seconds PERFECT FOR β’ Anyone about to reuse their usual password on one more account and wondering if it is still safe β’ IT and helpdesk people who need to show a colleague β not just tell them β why "Summer2024!" fails β’ Students and the security-curious learning what entropy and crack time actually mean β’ Building the one master password you will trust to guard everything else WHY NOT JUST TRUST THE METER ON A SIGNUP FORM? Those meters flatter you β most of them accept "P@ssw0rd!" as strong because it ticks the uppercase-digit-symbol boxes. PasswordStr checks your password against a wordlist of the most common passwords, expands leet-speak disguises, and prices every predictable span the way cracking software does. If the app says Strong, a cracking rig agrees. PRIVATE BY DEFAULT Analysis runs entirely on your iPhone. What you type is never stored, logged, or transmitted β no account, no cloud, no analytics touching your passwords. The text field even opts out of iOS password saving. Generated passwords copy as local-only and expire from the clipboard after 60 seconds. PREMIUM (PURCHASE REQUIRED) PasswordStr requires a paid plan β weekly, yearly, or a one-time lifetime purchase. Full access unlocks the complete toolkit: time-to-crack across all three attack models, the attacker's-view pattern breakdown, and the secure password generator. Type the password you have been worried about and get the honest verdict before an attacker does.
