PMR is a - scientifically proven - very effective relaxation method. It is recommended by doctors and therapists for many symptoms that are mostly stress-related, such as: • tensions • migraine or headache • inner unrest • sleep disorders • back pain / pain • states of excitement, • anxiety and panic attacks • high blood pressure • psychosomatic complaints • burnout • stress and much more With regular practice it is getting easier and easier to get into deeper relaxation states. If you have enough practice with the long form of PMR (Basic Form: 17 Muscle Groups), you can switch to the Short Forms with 7 and 4 Muscle Groups and finally to the mental form: Body Scan. Then you can relax your body just mentally. ALL COMMON 4 FORMS OF PMR • Basic Form (17 muscle groups) • Short Form I (7 muscle groups) • Short Form II (4 muscle groups) • Mental Form (Body Scan) for BEGINNER, ADVANCED and EXPERIENCED are taught and practiced in this app. This provides a total of 12 complete versions of the PMR. BASIC FORM: 17 MUSCLE GROUPS 1. Right hand and forearm 2. Right upper arm 3. Left hand and forearm 4. Left upper arm 5. Forehead 6. Upper cheek part and nose 7. Lower cheek part and jaw 8. Neck 9. Chest, shoulders and upper back 10. Abdominal 11. Buttocks and pelvic floor 12. Right thigh 13. Right lower leg 14. Right foot 15, 16, 17 (-> left side) SHORT FORM I: 7 MUSCLE GROUPS 1.

Chest, shoulders, back, abdominal, buttocks and pelvic floor 4. Both thighs, lower legs and feet MENTAL FORM: BODY SCAN Guided relaxation through the whole body, starting from the face to the feet. This guide is the last stage of the PMR, in which the perception is directed to individual parts of the body without tensing them. The relaxation is now only mental. Soothing imaginations will help you. MUSIC & NATURE SOUNDS You can choose between 5 relaxing music tracks and 17 nature sounds. The volume levels can be adjusted individually. If desired, music and sounds can also be used alone (without voice) to relax or fall asleep. OUTRO: FOR SLEEPING / WITH RETURN At the end of the exercises, there is an Outro for falling asleep or with return, which can also be omitted. DURATION OF TENSION & PAUSES FOR RELAXATION Select your preferred duration for tension and relaxation between the muscle groups. TIMER FUNCTION After the end of the exercise an unlimited time for the music and nature sounds can be set so to deepen your relaxation. NOTE This app can and should be used offline (flight mode).

ReceptionRating · Positive reviews · Number of ratings

HeartMath holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: HeartMath has 4.8K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 92% of Progressive Muscle Relaxation.'s written reviews are positive against 74% of HeartMath's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Progressive Muscle Relaxation. ships an update every 3 months, HeartMath every 3 weeks. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
