Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
PE.Mech
Read full descriptionHide full description
This app is aimed at mechanics part and includes 11 experiments about: kinematics, Newton's laws of motion, work and energy, momentum and impulse, periodic motion etc. It has some features: 1. You can set ideal conditions, for example: friction=0, air resistance=0, any gravity acceleration; 2. Show changing physical values by function diagram, free body diagram, energy diagram etc in real time to compensate for the lack of real experiments; 3. You can set any reasonable parameters to see different results, and calculate them by the descriptions to test your understanding; 4. Suitable for use in high school and college students; I hope this app can help you in your physics learning.

Verdict
The clearest difference is price: Biomolecules at Free against PE.Mech's $0.99. Biomolecules also leads on update cadence (every 2 weeks vs every 2 months) and device support (3 vs 1). PE.Mech's advantage is ads (none vs shown). On in-app purchases and iOS requirement there is nothing between them.
