Honestly, my first reaction mirrors yours - "an app that nags you like a partner?" That's a tough sell. But rather than dismiss it outright, let's break down the growth challenge.
The biggest red flag I see is positioning. You're trying to automate something inherently personal. People don't want to be "nagged" by an app, they want accountability. There's a subtle but critical difference. I've seen similar concepts fail because they leaned too hard on the "tough love" angle without proving the user actually values that friction.
From a growth perspective, you need to validate whether your target audience wants an external enforcer for routines. My go-to process would be:
- Survey your ideal user with a value-proposition test - not just "do you like the idea?" but "would you pay £5/month for an app that sends you reminders your partner would otherwise give?" Tools like Typeform or even a simple Google Form can surface real intent.
- Run a low-fidelity prototype - a WhatsApp bot or a no-code tool like Bubble. Get 50 people using it for a week and measure retention. If day-7 retention is under 20%, the concept doesn't have product-market fit.
- Analyse the competitive landscape - check Ahrefs or Sensor Tower for "accountability app" keywords. See what's working and what's getting panned in reviews. Screaming Frog can crawl app store pages for sentiment signals.
What did your initial market research show? The sample size might be too small or biased. I'd want to see data on why people would seek this - is it procrastination, relationship stress, or something else entirely? Without that, you're building on assumptions.
The core idea isn't dead, but the framing needs an overhaul. Position it as a personal coach, not a nagging spouse. Then test like hell before sinking dev time.
