Frequently asked questions about 1Flow
What counts as an MTU (Monthly Tracked User)?
Any user who opens your app or visits your website in the last 30 days. 1Flow only counts unique users, so if one user visits your website and uses your app for many sessions in that month, that user's activity still only counts as 1 MTU. This is equivalent to Monthly Active Users your team may already be tracking.
How many surveys can I launch with 1Flow?
Unlimited! You can have as many ongoing surveys as you'd like, and easily control the user experience with the Global Survey Throttling feature, which ensures a cooldown period before the same user can be recontacted.
How many responses can I collect with 1Flow?
Unlimited! From NPS, CSAT to customer preferences and product feedback, you can collect just about anything and utilize your data to improve your business.
How many team members can I invite to 1Flow?
Unlimited! 1Flow wants you to invite your whole team so everyone can stay in the loops of customer feedback. The world needs more customer-centric companies.
What happens if I exceed my plan's limits?
If you want access to features not included in your current plan, you'll be prompted to upgrade to the next plan. If you exceed the number of MRUs included in your plan, you'll be charged a nominal rate per additional MRU over the plan amount, with volume discount baked in.
Can I use the same plan for multiple sites or apps?
Yes, you can add unlimited sites and apps, and they will share the MRU quota included in your plan.
Can I upgrade or downgrade my plan?
