Aktiv Learning is an active learning platform built specifically for college-level chemistry and mathematics. Say goodbye to static content and generic multiple choice questions and hello to dynamic problems that are designed to help students learn and visualize abstract concepts in STEM. Aktiv Learning allows chemistry instructors to ask students engaging questions, such as drawing Lewis structures, and receive real-time information on what structures the class is drawing. The app features a custom-built tool that allows students and instructors to quickly and intuitively draw Lewis structures on mobile devices. Additionally, both students and instructors have access to over 250 built-in questions related to Lewis structures, resonance, molecular geometries, VSEPR, hybridization, sigma and pi bonding, and molecular polarity. Features: • Intuitive Lewis structures drawing tool built specifically for mobile devices - Use as engaging demonstration for your students to show example Lewis structures and reinforce concepts such as the octet rule, formal charge, and VSEPR. Students can take advantage of the drawing tool to visualize the relationship between Lewis structures and molecular shapes. • Create in-class or homework assignments - Perfect for clicker, recitation, or review problems. Students receive push notifications to alert and remind them of pending assignments. • Assign or practice with over 250 built-in questions related to Lewis structures, resonance, molecular geometries, VSEPR, hybridization, sigma and pi bonding, and molecular polarity. • Real-time class results - Quickly find common incorrect structures to address student misunderstanding before exams. • Isoform recognition - Aktiv’s technology recognizes correct answers independent of the drawn structure orientation. • Export student activity - Student participation and performance exported in a tap of a button. • Easy sign-up - Students and instructors can create accounts and join courses all within the app in a few steps. • School IT and device independent - Assign, work, and review from any mobile device and over any network connection.

RESEARCH RING: LAB GRADE PHYSIOLOGICAL DATA ACQUISITION PLEASE NOTE: The Senstream Researcher Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions or illnesses. The app is designed to record physiological signal data, but not to make medical decisions. Multi-Sensor: Electrodermal activity (EDA, aka GSR), ECG, PPG, temperature and motion, captured from a single, user friendly device with long battery life. Electrodermal Data: Our initial product is the first ring form factor device that captures electrodermal activity with lab quality, enabling new types of research. ECG and/or Pulse: Capture electrocardiograph (ECG) and/or photoplethysmograph (PPG) data, depending on the specific needs of a study or application. Temperature and Motion: Capture temperature data from the finger, and contextualize physiological data with motion data captured by the Research Ring. Mobile and Cloud Apps: Start capturing data with just a ring and mobile app, which seamlessly connects to the cloud. BIOPAC integration offers powerful tools. Bold Vision: The Senstream roadmap, supported by a rich patent portfolio, leverages the convenience and unique physiology of the finger. Stay tuned!

Verdict
The clearest difference is rating: Senstream at 4.3 against Aktiv Learning's 3.2. Senstream also leads on in-app purchases (none vs 1) and device support (4 vs 2). Aktiv Learning's advantage is ratings volume (184 vs 3) and update cadence (every 3 weeks vs every 3 months). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Aktiv Learning sells 1 one-off in-app purchase. Senstream asks for nothing beyond the download.
Senstream holds the better App Store score, 4.3 against 3.2. That said, the two scores are not equally well evidenced: Aktiv Learning has 184 ratings behind it against 3, so its average is the more settled of the two.
Aktiv Learning ships an update every 3 weeks, Senstream every 3 months. The most recent releases landed on October 14, 2026 and October 6, 2026 respectively.
