Thinksulin
Read full descriptionHide full description
Thinksulin was developed by ACI in consultation with the NSW Diabetes Taskforce and its In-hospital Management of Diabetes Mellitus Working Group and informed by: an evidence check of best practice care components of inpatient insulin management brokered by the Sax Institute for the Agency for Clinical Innovation (2024); clinician and consumer consultations; and clinical expertise. Thinksulin aims to enhance the capacity and/or capability of junior medical officers and nursing staff responsible for prescribing and administering of insulin to patients in hospital with diabetes, although it can be used by any clinician responsible for the care of people in hospital with diabetes. Thinksulin is a point of care app that provides information and decision support on blood glucose level targets, hypoglycaemia management, blood glucose monitoring, basal-bolus calculations, and charting and reviewing doses.
OSLA
Read full descriptionHide full description
OSLA measures the surface area of ocular surface lesions from a photo. Capture a close-up of the eye, mark the iris as an 11.5 mm reference, trace the lesion, and OSLA reports the area in square millimetres. Built for eye care clinicians and researchers who need a consistent, repeatable way to document lesion size in clinic or in the field. How it works: - Capture with the guided camera (near focus lock, flash at capture) or pick an existing photo - Draw around the iris. Its 11.5 mm average diameter sets the real-world scale - Trace the lesion freehand, or tap point by point - Read the area in square millimetres, with maximum and minimum dimensions The saved photo includes the annotations and a small measurement card, so the result can go straight into your records. Everything runs on the device. No account, no upload, no tracking. Photos stay on your phone unless you choose to share them. OSLA is useful for documenting and monitoring conditions such as ocular surface squamous neoplasia, pterygium and conjunctival naevi. It is a documentation aid for clinicians, not a diagnostic device, and it does not replace clinical judgement.

Verdict
The clearest difference is update cadence: OSLA at daily against Thinksulin's every 9 months. OSLA also leads on iOS requirement (15.0 vs 17.2). On price, ads, in-app purchases and device support there is nothing between them.
