Terms of use

Effective date: 8 October 2026

Stiffless is an iPhone app offered by Ali Çağlar, Yakacık Çarşı Mah., Tarihi Ayazma Cd., Kartal, İstanbul, Türkiye (“we”, “us”). By using Stiffless you agree to these terms.

Apple’s standard license

Your use of the app is governed by Apple’s Licensed Application End User License Agreement (the Standard EULA). The terms below add to it. If they ever conflict, the Standard EULA applies.

General wellness, not medical advice

Stiffless offers general wellness routines: short stretching and posture breaks meant to help you ease stiffness and take a break from sitting. It is not medical advice and does not replace a doctor, physical therapist or other health professional.

Move gently. Stop if any move makes your pain worse.

If you have an injury, recent surgery, ongoing or severe pain, numbness or weakness, or if you are unsure whether a move is right for you, talk to a doctor or physical therapist before you start. Read the safety screen in the app carefully and follow each move’s “skip this move if” notes.

You choose whether and how to do each move, and you are responsible for listening to your body. Only move within a range that feels comfortable.

Free and Premium

You can use Stiffless for free, including your first break, one full routine of the day, some library and quick relief routines, voice guidance, beeps and the easier version of each move. Stiffless Premium unlocks every routine and the other Premium features described in the app and on the App Store. There are no ads in either version.
