# SendMan vs 0Day

The clearest difference is update cadence: 0Day at every 5 days against SendMan's every 2 weeks. 0Day also leads on chart position (#193 vs unranked). SendMan's advantage is monetization model (ad-supported vs freemium) and device support (4 vs 1). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. SendMan sells 2 in-app purchases, starting at $1.99 per month and 0Day sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for SendMan against 5.0 for 0Day. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews split almost evenly too, at 100% and 100% positive.
