Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed the 1year subscription. Advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. They communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month and cancelled my future subscription. I would happily use this again. Thank you.
