Respi vs TapRate
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Respi
This app assists healthcare professionals in accurately measuring a patient's respiratory rate. It uses an innovative algorithm and a simple button press to calculate breaths per minute, accounting for user reaction time for precise results. Designed for regular breathing patterns, it ensures accuracy within 95% ± 1 breath/min.
- Accurate respiratory rate calculation
- Innovative algorithm

Respi-Rate helps healthcare professionals determine a patient's respiratory rate using manually recorded breath intervals. Press the Lungs button each time the patient begins to inhale. Respi-Rate estimates respiratory rate from the intervals between these button presses. The application does not automatically detect breathing and does not use device sensors to identify individual breaths. RESPI-RATE PRO Respi-Rate Pro adds tools for respiratory assessment and documentation: - Measurement history – review previous respiratory-rate determinations. - Breathing Regularity – assess the consistency of manually recorded breath intervals. - I:E Assessment – display the ratio of manually recorded inhalation and exhalation durations. This feature is experimental. - Age-based reference ranges – compare the respiratory-rate result with age-specific reference values. - Dark Mode – use an appearance optimized for low-light environments. All Pro features can be tried free for 7 days. No subscription. No automatic charge. The free trial ends automatically after 7 days, with nothing to cancel. Basic respiratory rate determination remains available free of charge. Pro can be unlocked permanently with a separate, one-time Lifetime Pro purchase. METHODOLOGY Respiratory rate is determined from breaths recorded manually by the user. For example, if the Lungs button is pressed at 00:00 and again at 00:05, with both presses made when the patient begins to inhale, the recorded interval is 5 seconds. This corresponds to an estimated respiratory rate of 12 breaths per minute (60 ÷ 5 = 12). After each press, the application evaluates whether enough respiratory intervals have been collected. If the required accuracy has not been reached, additional intervals are collected. With a regular breathing pattern, the algorithm continues collecting intervals until the estimated respiratory rate reaches an accuracy of 95% ± 1 breath per minute. Because breaths are recorded manually, results depend on consistent button timing. Press the button at the same phase of each respiratory cycle, preferably at the beginning of inhalation. Do not use Respi-Rate to determine respiratory rate when the patient's breathing is irregular. Respi-Rate Pro includes a breathing regularity assessment. When this feature is used, interpret the respiratory rate only when the regularity assessment reaches 3 stars. If fewer than 3 stars are achieved, repeat the measurement. The regularity assessment reflects the consistency of manually recorded breath intervals. It may be affected by irregular breathing or inconsistent button timing and does not represent the accuracy of the respiratory-rate determination. The experimental I:E Assessment depends on the accuracy of the user's button presses and does not establish a diagnosis. IMPORTANT Respi-Rate supports respiratory rate determination and does not replace clinical judgment. Always confirm unexpected results by direct observation. Interpret all results in the context of the patient's overall clinical condition and follow applicable clinical guidelines. Fast. Simple. Focused on respiratory rate.

Measure and calculate heart and respiratory rates using your iPhone or Apple Watch. All that's required is that you be able to feel a radial pulse rate or observe a respiratory rate, and then tap! TapRate uses math and sample timings to calculate a person's heart or breathing rate. It was designed for use by EMTs, Paramedics and other first responders but has also found a use in a variety of other fields, including Veterinary medicine. If you're not a medical professional please be aware that TapRate is a measurement tool. Seek a doctor's advice in addition to using this app before making any medical decisions. If you are an EMT and using it on duty, make sure to follow all your agency's guidelines and medical protocols. HOW TO USE -------------- Using the hand with your watch on it, feel for a radial pulse or observe a person's breathing rate by watching their chest rise and fall. Every time one of these events occurs, tap the button with a finger from your other hand. The indicated rate turns from orange to green after several samples have been collected and an average rate is calculated. It optionally turns red to reflect an elevated heart or breathing rate, if the rapid alert rate has been set. After a few recorded samples your rate will be displayed. Practice to become more proficient and accurate. If you're a healthcare professional (Nurse, EMT, etc.) be sure to practice and compare your rates to those obtained using more traditional techniques and/or diagnostic measurement tools. Once you're comfortable using TapRate you'll be able to obtain heart and respiratory rates within seconds, which is way faster than waiting 15 or 30 seconds doing the same thing manually. CPR METRONOME ------------------- TapRate also has a great CPR metronome when you're out in the field performing lifesaving CPR, or training. It allows you to customize the amount of time spent per round (how much time one person performs compressions), the rate (likely established by your agency or medical system) as well as offer audio prompts warning you when the round is almost over. Different metronome sounds are also available. PRE-ARRIVAL CONDITIONS REVIEW ------------------------------------------ On the way to a call, pick the patient's age group, then medical or trauma, then the presentation you're expecting. TapRate shows the causes usually worth considering, the red flags to look for, and which way each vital sign normally moves — measured against your own reference ranges. Everything is stored on the device, so it works with no signal and there's nothing to wait for. Note: This is version 3.0 of the original TapRate application first created and released to the App store in 2015!

Verdict
The clearest difference is in-app purchases: TapRate at none against Respi's 3. TapRate also leads on rating (5.0 vs 4.7) and update cadence (every 4 days vs every 8 days). Respi's advantage is ratings volume (118 vs 3). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Respi sells 3 one-off in-app purchases. TapRate asks for nothing beyond the download.
TapRate 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 3, so its average is the more settled of the two.
Respi ships an update every 8 days, TapRate every 4 days. The most recent releases landed on October 18, 2026 and October 6, 2026 respectively.
