Respi-Rate makes it easy to manually record observed breathing and calculate breathing frequency. Simply observe a person's breathing and use the Lungs button to record each visible breath. Respi-Rate calculates breaths per minute from the timing of the events you record. Depending on the breathing pattern and recorded intervals, the app may ask you to record additional breaths before displaying a result. KEY FEATURES • Manual breathing-frequency calculation • Simple, focused interface • Haptic feedback on supported devices RESPI-RATE PRO • History — review previously recorded measurements • Regularity — see how consistent the manually recorded intervals were • I:E Ratio — view the ratio between manually recorded inspiratory and expiratory phase timing • Age Reference Intervals — compare the recorded value with published age-specific reference intervals • Dark Mode Respi-Rate does not automatically detect breathing or use iPhone sensors to identify individual breaths.

ZapLock turns any folder in Files into a locked one — and back — without moving it. Pick a folder: On My iPhone, iCloud Drive, Dropbox, Google Drive. ZapLock encrypts every file in place, keeps the folder's name and location, and leaves nothing readable behind. A folder locked on your Mac opens here; one locked here opens on your Mac. UNLOCK WITH YOUR ZAPQR SIGN-IN Opening a vault is a sign-in, not a password. Face ID and the passkey ZapQR already put on this iPhone, or a magic link if you prefer. Nothing to remember, nothing to send over chat, nothing to leak. FILES OPEN INSIDE ZAPLOCK Tap a file and ZapLock decrypts that one file, shows it, and wipes the copy the moment you lock, switch apps, or the auto-lock timer fires. Leaving the app always locks — the app switcher never sees an open vault. SHARE, AND TAKE IT BACK Share a vault with anyone who has a ZapQR account. Each person unlocks it on their own device, with their own key. Remove them and their access ends, even on a vault they have open. YOUR KEYS STAY YOURS Every file is encrypted with AES-256. The key is split: one half never leaves this device's Secure Enclave, the other is released by ZapQR only while your sign-in and your share are valid. We can't open your folders, and neither can your cloud provider. File contents and file names never leave your device. PORTABLE BY DESIGN The vault format is open and documented, and the same on iPhone, iPad and Mac. A folder on a portable disk or inside a synced cloud folder carries its protection with it. ZapLock requires a free ZapQR account (auth.zapqr.ai). One universal app for iPhone, iPad and Mac. ZapLock Personal is an auto-renewing subscription: $4.99 a month or $49.99 a year (local prices vary). Payment is charged to your Apple Account; it renews unless cancelled at least 24 hours before the period ends, and you can manage or cancel it in your App Store account settings. Folders you already locked keep opening on every plan. Terms of Use: https://zaplock.io/terms Privacy Policy: https://zapqr.ai/privacy

Verdict
The clearest difference is monetization model: Respi at free with in-app purchases against ZapLock's subscription. Respi also leads on ratings volume (118 vs 1). ZapLock's advantage is rating (5.0 vs 4.7) and update cadence (every 3 days vs every 8 days). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Respi sells 3 one-off in-app purchases and ZapLock sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
ZapLock holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Respi has 118 ratings behind it against 1, so its average is the more settled of the two.
Respi ships an update every 8 days, ZapLock every 3 days. The most recent releases landed on November 11, 2026 and November 13, 2026 respectively.
