One is a therapy programme. The other is a fire extinguisher. Here is when you need which.
You are arguing about something specific. You each record your side. The AI compares both versions, names who was more in the wrong, and prompts an apology. One round, one verdict, done.
A self-guided therapy programme built by licensed marriage therapists. You start with a relationship health assessment, then work through structured series on communication, conflict, trust, intimacy, money, parenting. Sessions run 10 to 15 minutes, a few times a week, over several weeks.
Lasting is a course. Piece is a call. Lasting helps you change how you argue over time. Piece settles the argument you are having right now. If your relationship needs deep work, Lasting is built for that. If someone forgot to call and now the kitchen is silent, that is us.
Nothing until you need it. No assessments, no multi-week programmes, no progress tracking. Open the app, start a round, get a verdict. Close it.
Real commitment. Both partners complete an initial assessment. Then you work through sessions independently or together, a few times a week. The programme adapts to your pain points but it still takes weeks to finish a series. It works best when both people follow through consistently.
Lasting asks you to invest in your relationship like you would invest in a fitness plan. Piece asks for five minutes when a specific argument stalls. If both of you will commit to weekly sessions for months, Lasting rewards that. If you just need the deadlock broken tonight, it is overkill.
Free with ads. No subscription.
Starts at about $30 per month. Multi-month plans bring it down (roughly $15 to $20 per month on longer commitments). A free Foundations series gives you five sessions to try it. Therapists can prescribe it to clients at a bulk discount.
Lasting costs real money because it delivers real therapy content. Piece is free because settling one argument does not need a subscription. If you are choosing between them, the deciding factor is not price. It is whether your problem is a pattern or a moment.
Lasting is for couples who know they need to work on things. Piece is for couples who need to get past one specific fight before they can think about anything else. One builds new habits. The other breaks one deadlock. They are not competitors. They are different tools for different days.
