# Post vs ABUS One

The clearest difference is review sentiment: ABUS One at 66% against Post's 30%. ABUS One also leads on monetization model (free vs ad-supported). Post's advantage is rating (4.8 vs 4.6). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Post holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 117 and 58 respectively.
