AXIS ASSISTANT is an App conceived as a tool to: find a given angle, detect tilt and also to measure a sector size in degrees. This tool can be useful in many applications such as: • The steepness of a slope; • Can be used for hanging pictures, diplomas or photographs on a wall; • Useful for photography to detect the horizon; • It measures the angle of an arc (for example in architecture); • And much more, your imagination is the limit. ## Key features - Find a given angle - Detect tilt - Measure sector size in degrees - Assess slope steepness - Aid in hanging pictures - Detect horizon for photography ## Recent user reviews (10 of 17) All indexed reviews: https://appshunter.io/ios/app/axis-assistant/id843536178/reviews.md ### 4/5 — Working again *2026-06-09, version 2.4* Thank you for fixing the crashing app when I use the camera ### 1/5 — Camera *2026-05-05* Camera nao funciona mais **Developer response:** Hello. The camera feature is now working. New features include torch, zoom and AppleWatch companion App. ### 5/5 — Great toric tool *2026-02-06, version 2.1.1* I have used this for years for confirming the position of preoperative toric axis marks on the cornea as well as for measuring exact IOL position at the slit lamp. I did not realize others were using this app exactly the same way. The camera view is especially useful/necessary for visualizing the position of the marks on the cornea preoperatively. The camera has quit working in the latest version (or perhaps a bug with the latest iOS). Now selecting the camera from within the app does not work but goes to the phone’s home screen. Hopefully this can be corrected soon. Fantastic app. ### 5/5 — Great toric tool *2026-02-03* I have used this for years for confirming the position of preoperative toric axis marks on the cornea as well as for measuring exact IOL position at the slit lamp. I did not realize others were using this app exactly the same way. The camera view is especially useful/necessary for visualizing the position of the marks on the cornea repetitively. The camera has quit working in the latest version (or perhaps a bug with the latest iOS). Now selecting the camera from within the app does not work but goes to the phone’s home screen. Hopefully this can be corrected soon. Fantastic app. ### 1/5 — Não abre a câmera *2025-10-04* Sempre gostei , usei muito … Na nova atualização do iOS ele perdeu a função de abrir a câmera para poder confirmar as marcações diretamente da câmera no giroscópio …Qdo ativo a função da câmera o app sai … Tem como resolver? **Developer response:** Hello. The camera feature is now working. New features include torch, zoom and AppleWatch companion App. ### 3/5 — Help! *2025-09-24* I’ve used this app for years, but it’s no longer working with the latest update of iOS and iPhone 17. When I try to open the camera, the app crashes. ### 5/5 — Axis Assistant is brilliant, simple to use *2023-05-02* This app is an essential tool for Ophthalmologists using toric lens implants. It is very useful and accurate. I recommend it to all ### 5/5 — Toric IOL axis *2020-12-22, version 2.1.1* As an Ophthalmologist I have used this app on an almost daily basis to measure the exact axis of a Toric IOL in the post op period. It is accurate to 1 degree in the clinic and is essential to obtain the IOL axis especially for input in the Berdahl/Hardten Astigmatism Fix calculator to evaluate if a Toric IOL should be rotated. Just sit patient at slit lamp. Have them look into the beam. Rotate the beam to align with the IOL axis. Have patient sit back and hold cell phone up to the slit lamp and adjust the axis line in the app to be coincident with the slit beam while looking through the slit lamp. Extremely accurate and fast. Congratulations to the authors of this most useful medical tool. ### 5/5 — Toric IOL helper *2020-12-08, version 2.1.1* Useful tool to record axis of an IOL in situ when your slit lamp doesn’t have a protractor. Also useful to plan manual AK arcs by entering the axis and arc length. ### 1/5 — Not useful *2019-09-03, version 2.1.1* Camera does not come up. Not useful. ## Frequently asked questions about Axis Assistant ### What can Axis Assistant measure? Axis Assistant can find a given angle, detect tilt, and measure a sector size in degrees.
