Two apps, two different questions
These are the two most-compared stretching apps, and they are less alike than the category suggests.
Bend is a library of illustrated routines with a timer, plus a builder for making your own. It runs on iPhone and Android, keeps a streak and a progress dashboard, and has a free tier. Its model is daily maintenance: open it, pick something, do it, watch the number go up.
STRETCHIT is a class platform. An instructor leads you through a video session. More than a hundred hours of instruction, new classes weekly, sessions from five to forty-five minutes, aimed at people working towards flexibility goals like splits and backbends.
So: a library and a timer, against a teacher and a curriculum.

How to pick between them
Pick Bend if the thing you want is a quick, repeatable routine you can fit into a weekday, you like seeing a streak, or you want to assemble your own sequence from a large stretch library. Its free tier also makes it the lower-risk download of the two.
Pick STRETCHIT if you have a goal rather than a habit problem. Splits, a backbend, a home practice that feels like a class. An instructor demonstrating unfamiliar movements is worth a lot, and a timer cannot replace it.
Pick neither if the honest obstacle is that you will not open a fitness app at all, which is the third case and the reason this page exists.
The third case
Here is the situation both of those apps handle less well, and where we have an obvious interest, so weigh it accordingly.
You sit for eight hours. You are not training for anything. You have downloaded a stretching app before, used it for nine days, missed a Wednesday, seen the streak reset and never opened it again.
That is not a content problem and a bigger library does not solve it. Bend's streak is a feature for people it motivates and a trapdoor for people it does not. STRETCHIT's forty-five-minute classes are wonderful and not something you will do at 6pm on a Thursday.
Lucy is built for that case specifically: sixteen routines, nothing past six minutes, and no streak anywhere in the app. The progress screen counts the days you showed up and does not count the days you did not.
It is also the narrowest of the three. iPhone only, no Android build. Smaller library than either. No instructor and no video classes. One routine free in full rather than a broad free tier. If what you wanted from this page was the biggest or the most taught, the answer is above, not here.
What Lucy is, and what it is not is the page that sets that out properly, and Lucy vs Bend is the direct comparison.
What the research says about length
Relevant to all three, because session length is the main axis these apps differ on.
A 2025 meta-analysis in Sports Medicine, pooling 189 studies and 6,654 adults, found thirty-second holds working as well as sixty-second ones, session gains flattening at roughly four minutes per muscle group, and weekly gains flattening at about ten minutes per muscle group with no advantage to any particular distribution across sessions.
Read carefully, that says a long session is not required for flexibility gains. It does not say a class is a waste of time: a class covers many muscle groups and is also something people enjoy, which is its own argument.
What none of them does
All three are general fitness and wellness products. None provides medical advice, diagnosis or treatment, and none is adapted to a specific injury or diagnosis.
If you are stretching around an injury, a pregnancy or a diagnosed condition, a professional is the right first stop regardless of which app you choose. Our fitness and safety note sets out Lucy's position, and never force a stretch to reach a shape you have seen demonstrated.
FAQ
Is Bend or STRETCHIT better?
Neither in general. Bend is better for short daily maintenance and has a free tier; STRETCHIT is better if you want an instructor and a flexibility goal with structure behind it.
Is Bend or STRETCHIT better for beginners?
STRETCHIT gives a beginner a teacher, which helps with unfamiliar movements. Bend gives a beginner a lower time commitment and something free to start with. The deciding factor is whether your obstacle is knowledge or time.
Do Bend and STRETCHIT both have free versions?
Both are free to download. Bend has a free tier of routines with a premium upgrade. STRETCHIT is a subscription with a 7-day free trial rather than an ongoing free tier. Check both listings, since this changes.
Which has longer sessions, Bend or STRETCHIT?
STRETCHIT, with classes up to forty-five minutes. Bend's routines are generally shorter, though it offers longer options than a strictly capped app would.
What is a good alternative to both?
Depends why you are looking. For more content and athlete-focused mobility, Pliability. For short routines with no streak and no account, Lucy, which is ours. There is a fuller list at Bend alternatives.
