Evidence basis, how to recommend, and clinical feedback channels for Stroke Sight and ReWrite — rehabilitation support tools designed to complement your work.
Both tools are grounded in published rehabilitation research. Neither claims to be a clinically validated tool — they are wellness support tools designed to complement professional care.
Stroke Sight's hemianopia exercises are based on the compensatory saccadic scanning approach described in NICE NG236 (Stroke rehabilitation in adults, October 2023) and four decades of research:
The neglect exercises use smooth pursuit eye movement training — an approach described in German Neurological Society guidance and in the Klinke et al. (2015) systematic review. Spatial auditory cues draw on the multisensory stimulation research of Bolognini and Tinelli.
Scotoma exercises provide awareness training around the blind spot area.
ReWrite provides structured tracing practice using principles from the graphomotor rehabilitation literature. Repetitive, task-specific practice is the strongest evidence base in stroke motor rehabilitation:
Session length is designed around typical post-stroke fatigue windows. Content is language-specific — not translated — supporting rehabilitation in the patient's first language.
ReWrite's Word Builder offers word-finding and spelling-by-hand practice: a word stem is completed by choosing the right ending, traced, then written from memory. For people with aphasia whose goals include written language, that practice can sit alongside your sessions — keeping writing active as an expressive modality between appointments, in the person's own language rather than a translation.
ReWrite supports independent practice. It does not assess or treat aphasia, and it is not a substitute for speech and language therapy — you set the goals; it helps with the repetitions.

Both apps are paid App Store apps, so licences can be bought in volume through Apple Business Manager (Apps and Books) and deployed to managed iPhones and iPads with your MDM — licences stay with the organisation and can be reassigned as devices change hands. Managed Google Play does not currently support volume purchase of paid apps, so for a managed Android roll-out please get in touch and we will arrange licensing directly. Invoiced purchasing and a dedicated Clinic tier are in development.
Email about a clinic purchaseEye-Search and Read-Right are free, university-developed web tools: Eye-Search offers visual-search practice for people with visual field loss, and Read-Right offers reading practice for hemianopic alexia. Both were developed entirely independently of Ansteyapps — we are not affiliated with them, and they have no connection to our apps. We mention them because patients are best served by knowing every free resource that exists.

Stroke Sight is a separate option: structured scanning practice as an app, working offline on a phone or tablet, with adjustable difficulty and progress reports, for a one-time purchase.
These tools are built to complement clinical work and improve with clinical input. Feedback from clinicians is taken seriously and directly informs development.
A printable one-page evidence summary is available for circulation in clinical teams. It covers both apps, their evidence basis, and how to recommend them to patients.

liam@ansteyapps.comIf you are looking at ReWrite or Stroke Sight for a ward, a clinic or a charity rather than for one person, there is a separate page covering volume purchasing through Apple Business Manager, redemption codes for Android and Fire fleets, invoicing, free evaluation codes for your team, and the information-governance position — no data is collected, so there is no DPIA, no data processing agreement and no supplier security questionnaire to complete.
