# iSectionLite vs DWG FastView

The clearest difference is rating: DWG FastView at 4.5 against iSectionLite's 1.8. DWG FastView also leads on update cadence (every 4 weeks vs every 46 months) and ratings volume (1.1K vs 12). iSectionLite's advantage is in-app purchases (none vs 9) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. DWG FastView sells 9 in-app purchases, starting at $0.99 per month. iSectionLite asks for nothing beyond the download.
