High-school, college, Olympic and non-elite runners have all trained, ran, and succeeded with the VDOT methodology. -”Dr. Jack Daniels has had a bigger influence on training-for-running than anyone. He might be considered the Albert Einstein of the sport." - Runner’s World Magazine

Verdict
The clearest difference is in-app purchases: AIM Virtual at none against V.O2's 17. AIM Virtual also leads on review sentiment (100% vs 71%) and device support (4 vs 2). V.O2's advantage is update cadence (every 6 days vs every 6 weeks) and ratings volume (6.2K vs 23). On price, rating, ads and iOS requirement there is nothing between them.
