Ads may well be necessary. BUT the level of intrusion in this app is absolutely taking the Mick. Very good app BUT. 1 star for intrusive ads. I would pay put can not justify the cost over low usage. AND.. the the app does jot say what you get when paying. Does paying simply removes ads. Or is there other features. AND us this a oneboff payment or not. Not payingbfor something I do not know what ibam paying for.

Thought it would be good for adding measurements to a photo for sizing a job, but you can't zoom into an image enough. Moving an image around is difficult too. Picking up the end point of an existing line or angle is hit and miss and often it just thinks you want to draw a new line which is really annoying. This could be a useful app, the basics are there, but it's implementation is lacking for any detail work, which is odd considering it's supposed to be a 'technical tool kit'.

Hi, thanks for your details feedback. You can zoom then move the image with 2 fingers(or you can use pan tool). For selecting point, it could be difficult for people with big finger then you can change touch mode in the app settings. If you have any more problems then you can write us at support email annotium@gmail.com

Its 'okay'....very confusing just to change text colours..no explanation as to what each button does and feels very over valued. $9? Lol thats a joke right? You can get PC apps with a lot more features for less. Lower your price and don't give my that craap that you don't need to pay for it. That proves you know its over priced but you make more from ad rev. Fix how there's no text to say what each button does.

Thank you for your feedback. The price goes up because of your country tax. Most of tools in app are free and enough for regular users. Only extended are charged. You can turn them off in settings if you want. We're building documentation to help new users can easily start with the app. Best regards
