How post-purchase survey apps compare
The biggest difference between these apps is how the price grows. Some charge by orders, some by responses, some a flat fee.
| App | Monthly price | How the price grows | Free option |
|---|---|---|---|
| TracePoll | Free, $19, $49, $99 | Flat price, unlimited orders on paid plans | Up to 200 orders a month |
| Zigpoll | Free, $39, $129, $399 | By number of responses | Limited responses |
| Fairing | $49 to $149+ | By number of orders | Free under 200 orders a month |
| Grapevine | $25 | Flat price | Free trial |

When another app is the better fit
Fairing has years of benchmark data and a large agency network. If you want an agency to run your surveys, start there.
Zigpoll runs surveys on many pages, not only after checkout. If you need on-site polls and email surveys, it covers more ground.
Grapevine and KNO are simple and inexpensive for low-volume stores.
When TracePoll is the better fit
- Your order volume changes a lot and you don’t want the bill to change with it.
- You want return on ad spend next to channels you don’t pay for, like word of mouth.
- You want to ask ChatGPT or Claude questions about your survey data.
- You sell in several languages. TracePoll shows the survey in 13.
