Verdict
The clearest difference is monetization model: VoltOnoSprint at free with in-app purchases against FAST!'s subscription. VoltOnoSprint also leads on device support (4 vs 2). FAST!'s advantage is update cadence (every 3 days vs every 3 weeks) and iOS requirement (12.0 vs 15.4). On price, ads and in-app purchases there is nothing between them.
