Where Oh My Dots looks appealing
Oh My Dots clearly does a few things well from the first impression. It is free to start, easy to understand, and set up like a game creator. The visible workflow includes cropping the image, drawing the dots, previewing the game, choosing title or type, and even creating custom sequences.
That makes it attractive for people who want to build a playable or printable activity quickly without worrying about a commercial worksheet workflow from the beginning.
Where ActivityBookLab pulls ahead
ActivityBookLab becomes the stronger option when your question changes from "Can I make a connect-the-dots activity?" to "Can I make a connect-the-dots worksheet that still looks good enough to sell or publish?"
The biggest difference is not just free versus paid. It is game-style generation versus production-style worksheet control.
ActivityBookLab was designed around preserved inner lines, deliberate dot placement, and selective erasing. That matters when you are preparing pages for Amazon KDP, Teachers Pay Teachers, Etsy, or printable packs where page quality has to hold up across a whole product line.
