Sperata — contraction timer and breathing Record contractions, keep track of their duration and intervals, and choose a comfortable breathing rhythm. Sperata brings the tools you need together in a calm, clear interface on iPhone and iPad. Created with our own experience of expecting a baby in mind, the app focuses on simplicity, ease of use and what really matters in the moment. A timer without extra steps Tap when a contraction starts and again when it ends. Sperata calculates its duration and the interval from the start of one contraction to the start of the next. Afterwards, you can rate the intensity based on how it felt, or skip the rating. Your rhythm at a glance See a visual timeline of your last five contractions, the count for the last hour, and a summary of duration, intervals and intensity. Interactive charts let you explore saved values without calculating them by hand. The free version includes insights for your five most recent records. Breathe at a comfortable pace Follow a visual inhale-and-exhale rhythm during a contraction, or use separate breathing exercises between contractions. Following the rhythm is optional: use it only while it feels comfortable and follow your midwife's or doctor's guidance. What you need, close at hand Widgets and Live Activities show timer information and recent contractions on supported devices, without having to open the app each time. More with Sperata Pro • Apple Watch: start and stop the timer, rate intensity and use breathing exercises on your wrist. The watch works with your paired iPhone; no separate subscription is needed. • PDF reports: create a report on your device, then save, print or share it with a recipient you choose. • Extended insights: compare durations, intervals and intensity ratings across all your saved contractions. No registration or ads You do not need a Sperata account to use the timer. Saved records are encrypted on your devices and are not automatically sent to the developer. Data may be included in device backups. A PDF is created only when you request it. About subscriptions Core features are free. Sperata Pro is available as a weekly or monthly auto-renewable subscription. Both plans unlock the same features. The price is shown before you confirm a purchase. You can manage your subscription and cancel renewal in your Apple Account settings. Important Sperata records contraction times and your subjective ratings. It does not provide medical advice, determine whether labor has started or how it is progressing, or tell you when to seek care. Do not delay seeking medical help based on information in the app. Follow your midwife's or doctor's guidance. SOUNDS Choose white, pink or brown noise and set a timer from 1 minute to 5 hours. Listening is free while the app is open. Pro adds background and screen-locked playback, plus sound controls in widgets and Live Activities. Without Pro, these surfaces show status and open the app. See Help for listening precautions, especially near a baby. Keep the volume low and limit listening time. Sounds do not guarantee sleep; five hours is a timer limit, not a recommendation for a baby.
