EyeCanDo vs Tihi

EyeCanDo is an app to support eye gaze-based communications for people with limited mobility and communication due to disability. A user can control the app entirely using eyes, to ask for help, type messages, play music, among others. To use the app, you will first set up your device(iPad or iPhone) for positioning properly. Make sure your device is in front of your face and look still at the activate button to enter. After setup, you will need to do calibration. Make your eye gaze follow the blue dots during the calibration process and click the back button when you finish. After the calibration, you can go to the main interface of EyeCanDo. Some example functionalities include: Text to Speech: built-in phrases expressing feeling, need or basic answers. When an item is selected with gaze, a speech synthesizer will utter the sentence. Music: You can play your music from your Apple Music with eye gaze for selection and control. Emergency: When selected, a siren will be played for asking emergency help. Typing: You can use eye gaze to type with a virtual keyboard. Settings: You can customize the app, such as changing brightness and volume.

Tihi is a minimalist app for silent, instant communication when words are hard. Send pre-set signals or custom messages to your support person with a single tap—no explanations needed. Perfect for neurodivergent individuals, people experiencing anxiety or overwhelm, students needing discreet support, and their caregivers, teachers, or support partners. Choose from built-in signals like Overwhelmed, Need Break, Need Quiet, Need Help, Can't Focus, Sensory Overload, Need to Move, Need to Talk, I'm Good, or create your own custom messages. Connect two ways: Local Mode uses Bluetooth/WiFi for nearby communication (no internet required), or iMessage Mode sends signals anywhere in the world through Messages—perfect for remote support or family members in different locations. Signals arrive instantly with notifications and haptic feedback, even when the receiver's phone is locked. Review signal history to identify patterns, and rest assured all communication is private—no data collection, no accounts required. Real examples: A student silently signals their teacher for a break. A child alerts their parent they need quiet time. Someone with anxiety discreetly asks for support during a meeting. College students or adults living independently can reach their support network anywhere via iMessage. Tihi was designed with input from neurodivergent individuals to remove the barrier of finding words and provide a simple, dignified way to ask for support. Note: Tihi is a communication tool and not a substitute for professional medical or therapeutic support.
