# PROSYS vs Stash

The clearest difference is review sentiment: Stash at 100% against PROSYS's 0%. Stash also leads on rating (5.0 vs 4.4) and update cadence (fortnightly vs every 18 months). PROSYS's advantage is in-app purchases (none vs 2) and ratings volume (5 vs 1). On price, ads and device support there is nothing between them.

Stash holds the better App Store score, 5.0 against 4.4.
