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.

Verdict
The clearest difference is rating: Codon at 5.0 against Aktiv Learning's 3.1. Aktiv Learning's advantage is ratings volume (186 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Aktiv Learning sells 1 one-off in-app purchase and Codon sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Codon holds the better App Store score, 5.0 against 3.1. That said, the two scores are not equally well evidenced: Aktiv Learning has 186 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 6, 2026 and November 10, 2026 respectively.
