Based on the data on this page, Mega Callback is the stronger choice for most Shopify App Store merchants — 5.0★ vs POWR Contact Form Builder's 4.6★ is a meaningful gap that usually reflects real product or support quality differences across the user base. Pricing entry tiers: Mega Callback at Free plan available, POWR Contact Form Builder at Free plan available. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (apps, orders, integrations) varies. POWR Contact Form Builder has the larger user base (681 reviews vs 12), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns. Mega Callback's smaller cohort can be an advantage for niche workflows where the bigger app has accumulated bloat. Recommended by store size: small/early-stage merchants who need fast install and low risk should default to Mega Callback; mid-market and enterprise merchants with specific feature requirements should evaluate both — POWR Contact Form Builder's 681-review base may include the workflow context that matches your specific use case better than Mega Callback's broader-but-shallower coverage. This verdict is generated from the live marketplace data on this page — rating, review count, pricing tier, and category position all refresh from the canonical Shopify App Store listing every 24 hours. AppRanks does not accept payment to influence comparison outcomes; the methodology is documented on the About page and applies identically to every pair on the site.

I have had several issues with this app. EVERY TIME I try to create a new form, I run into some kind of problem. They do have a support team that tries to help, but the process is often slow, and the issues are usually with very basic things that should work without requiring technical support. What is most frustrating
Migration support varies by app and category. Mega Callback and POWR Contact Form Builder both publish their export options on their marketplace listing pages (or in their support docs); some apps offer one-click import from competitors, others require CSV. The fastest check: search "import from Mega Callback" in each app's help center. AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.
