5 stars!!
“I recently had the pleasure to work with support soft technology- app developers. I would happily give them 5 stars.. my app is in the disability sector called bloom roster care. It’s a personalised shift rostering system. I came to them with it just as an idea and dream. But they explained things so well I decided then and there to give it a go. Rob Sandeep and the team have gone above and beyond to support me. I had many questions that were always answered thoroughly and with reassurance.”
