Couples Accountability

My goal in this couples accountability project is to help couples improve communication, build trust, and resolve disputes between them meaningfully. We plan to measure the progress in real-time using a 1-10 scale along the categories we establish for them. Each couple will have daily check-ins where they can discuss their current situation. From there, they’ll set weekly goals for themselves and do a weekly progress evaluation. I envision this project to be a mobile app, accessible anywhere, as accountability tracking should take place in this format. As their coach, I'd like to see their progress in real-time as they rate their partner's progress. I've been considering Google sheets, but am open to suggestions.
