The clearest difference is in-app purchases: Arnold Split at none against Caliber's 10. Arnold Split also leads on review sentiment (100% vs 78%). Caliber's advantage is ratings volume (6.1K vs 2) and update cadence (fortnightly vs every 6 weeks). On price, rating, ads and device support there is nothing between them.

Both are free to download. Caliber sells 8 in-app purchases, starting at $3.00 per month. Arnold Split asks for nothing beyond the download.

Arnold Split holds the better App Store score, 5.0 against 4.8.
