Flowen vs Stamurai
By Howard Henry
Both tools help adults practise speaking when they stammer. They take different approaches. Stamurai is a speech therapy app for stuttering (its own description): guided plans and group sessions on iOS and Android. Flowen is a practice space that runs in the browser, with live visual feedback while you speak. Here is how they compare, feature by feature.

Where each fits
Stamurai may suit you better if

- you prefer a structured therapy programme on your phone, including tools like DAF
Flowen may suit you better if
- you do not want to install an app: Flowen runs in the browser
- you want live visual feedback while you speak
- you want your speech and language therapist involved: a live clinician platform supports assignment, session review, programmes and messaging (by arrangement)
- you want an identifiable UK company behind the product: your contract is with Flowen Speech Technologies Ltd, registered in England and Wales (Companies House no. 17470700), and prices are in pounds
