Heart-rate measurement and AI allowance
PulseRest does not require an app account. One local start time begins 7 × 24 consecutive hours of measurement access at first launch. New heart-rate measurements require an active subscription after that period. The period includes no AI replies: the AI assistant requires an active subscription verified on your device by Apple StoreKit. Existing records, waveform replay, individual PDFs, deletion and past conversations remain accessible.
An active subscription verified on your device by Apple StoreKit provides measurement access and up to 50 AI replies per device per local calendar day. The daily allowance resets at 00:00 in the phone’s current time zone; it is not rolling and is not shared across devices. Follow-ups count. A request reserves one local slot; the first non-empty reply content counts once, including a partial reply followed by cancellation or disconnection. A failure without reply content does not count. Streaming fragments and recovery of the same request do not count again. Requests crossing midnight belong to their sending day. Weekly and yearly plans provide the same benefits.
A reply that has begun to appear counts once even if local saving later fails. In-flight requests may temporarily reserve allowance. Network, provider capacity and security restrictions still apply; AI availability is not guaranteed. Opening Home does not make another AI request.
Does clearing local data restart access?
No. The original start time is kept separately in the device Keychain. Clearing measurements and chats does not restart access, reset AI usage or cancel an Apple subscription. An older installation with no reliable start record establishes one only at its first launch of the version with seven-day measurement access. Preservation after device erasure or every reinstall scenario cannot be promised. If the date cannot be read, retry or contact support; this does not grant another seven days.
How to measure
Open the illustrated seated and lying-down guide. Both positions use the same left-chest placement shown in the app.
Read the safety information before measuring. Place the back of the phone firmly against the left chest above the heart, screen facing out. Keeping still is an important step in reducing interference. The five-second preparation countdown does not measure or record. After the start cue, breathe naturally and stay still for 30 seconds. Both seated handheld and resting supine use are supported without a posture selector.
Talking, hand movement, clothing, contact pressure and device differences can affect estimates. The requested sampling rate is 100 Hz; timestamps determine the actual rate. Results show estimated heart rate only. This version does not estimate breathing rate or read or sync Apple Health data. The trace is mechanical chest movement, not an ECG. The app does not measure blood pressure or blood oxygen, detect atrial fibrillation, or diagnose disease.
Single-measurement PDF reports and local records
Export a PDF immediately from the measurement result or later from that record's details. The report contains estimated heart rate, recording time, device/version information and three ten-second waveform strips, without a point-by-point waveform appendix. Raw ZIP/CSV and bulk PDF export from Settings are not offered. A loading state appears while the report is being generated; wait for completion before sharing.
Delete individual records, or delete all local records in Settings. Choose recipients carefully when sharing health PDFs. Deleting local records does not automatically delete previously shared files or data held by providers.
AI sharing
Home shows AI guidance only when it belongs to the latest saved measurement. If that measurement has no saved guidance, choose Analyze this result; earlier advice remains in its original conversation. This action attaches the result locally without sending it.
Analysis can show a one-time subscription introduction during a visit when the app confirms no active subscription and no previous purchase. A known purchase or a subscription confirmed during that visit prevents repeated automatic offers. You can still open plans or manage your subscription yourself. Previous purchases alone do not unlock AI; sending a new question requires a currently valid Pro subscription. Purchasing or restoring access preserves the selected result and draft, but never sends a question automatically.
Analysis never auto-sends. With active Pro access, explicit consent and an active send, information passes only through our ECS servers to DeepSeek or PoYo; the app contains no provider API key or direct-provider route. The first request in a new measurement-linked conversation includes necessary results and an available processed, sampled chest-motion waveform, not raw multi-axis IMU samples. After the first complete reply is saved, follow-ups include necessary results and relevant chat without resending the waveform. An initial retry, an unsaved reply or failover may transmit the initial context again. See the Privacy Policy for recipients, retention and deletion boundaries.
Subscriptions, restoration and cancellation
Open PulseRest Pro in Settings to view weekly and yearly plans. Apple's purchase confirmation displays the applicable price and billing period. Subscriptions renew automatically. Restore purchases in the app, or manage and cancel in iPhone Settings → Apple Account → Subscriptions. Cancel at least 24 hours before the current period ends to avoid renewal. Deleting the app does not cancel a subscription. After subscription expiry, AI is unavailable. New measurement continues only if the original seven-day measurement period is still active. Existing records, PDFs and past chats remain accessible.
Product names and local prices come from Apple. If plans load slowly, check your connection and retry; do not buy again just because information is temporarily unavailable. StoreKit verifies membership on your device, without ECS membership sync. If Apple has not provided your verified purchase, use Restore Purchases with the purchasing Apple account. Contact support with your app version and a screenshot without payment credentials; never send passwords or card details.
After a purchase or restoration is verified and saved locally, the app returns to the previous screen and shows one brief “Subscription successful” or “Purchases restored” message. Reopening the plans page does not replay that message. Routine background checks stay quiet; they still handle renewals, expiry, refunds and revocations. The absence of a recurring “Membership updated” notice does not mean access has been lost.
AI after reopening the app
The app checks membership and daily usage locally without waiting for ECS membership or allowance synchronization. Apple subscription information may still need to refresh. Clearing local content, restarting, restoring purchases or changing plans does not refill today’s allowance. To first authorize or renew an AI service session, ECS verifies Apple-signed purchase evidence and binds a limited-duration, revocable session to this installation’s signing key. Ordinary requests reuse a valid session with signature, anti-replay, reasonable concurrency, abnormal-frequency and timeout protections; they do not query Apple for every message. ECS does not enforce this version’s daily reply quota. First authorization, renewal and actual replies need internet access; a temporary network or authorization failure does not require another purchase.
Entering Analysis reuses an already verified subscription while it remains valid. Renewal, expiry, refunds and revocations are still checked through Apple; purchase history does not replace verification of a currently valid subscription. A cached AI session remains bounded by the verified subscription expiry and may be revoked. If service authorization is temporarily unavailable, check your connection and retry; buying again does not repair a network or session problem. Contact support with safe diagnostic codes if it continues.
This version no longer requires App Attest or waits for its rejected-device-key recovery cooldown to authorize AI. Older app versions retain their earlier device-verification path. If an older version still shows a device-proof or key-cooldown error, update to the current version and retry. Do not share purchase credentials, signing keys or passwords with support.
Clearing measurements and chats retains protected installation credentials, current daily usage and the original seven-day start. The counter does not sync with other devices. An active app refreshes at midnight; if closed, the next launch applies the new day.
Suggestion safety
AI provides general lifestyle information, not medical advice. Check allergens, personal dietary restrictions and food/medicine interactions before trying specific foods. Measurements cannot rule out allergies or contraindications, and not every contraindication can be identified. Consult an appropriate clinician, pharmacist or nutrition professional when uncertain. Do not stop, substitute or adjust medication based on AI. Seek timely medical help for chest pain, severe difficulty breathing or fainting; do not wait for measurements or AI.
