Verdict

The call

The clearest difference is price: スピードメーター at Free against Disk Decipher's $0.99. スピードメーター also leads on in-app purchases (none vs 8) and update cadence (daily vs weekly). Disk Decipher's advantage is ads (none vs shown) and chart position (#122 vs unranked). On device support there is nothing between them.
