Take a new photo or pick a photo from your photo library and then count objects on it by tapping them. Save screenshots and/or share them via email or social networks. Use the Line tool when you need to mark a sequence of objects with equal distances between them (note: this doesn't work well with object viewed in perspective). Use the Multiplication tool to count objects positioned in 'rows' and 'columns'.

Verdict
The clearest difference is ads: Sigma Counter at none against Image's shown. Sigma Counter also leads on iOS requirement (9.0 vs 17.7.2). Image's advantage is update cadence (fortnightly vs every 52 months). On price, in-app purchases and device support there is nothing between them.
