# viProject vs GanttMaster

The clearest difference is review sentiment: GanttMaster at 100% against viProject's 37%. GanttMaster also leads on update cadence (weekly vs every 2 weeks) and device support (3 vs 1). viProject's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.1).

Both are free to download. viProject sells 4 in-app purchases, starting at $7.49 per month and GanttMaster sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
