Best Form Builder Apps for iPhone & Android (2026)
Quick answer: If your data should end up in Google Sheets, use Google Forms — via FormMaker on your phone, since Google makes no official mobile app. If you live in Microsoft 365, use Microsoft Forms. For polished standalone surveys, Typeform or Jotform. For serious research, SurveyMonkey.
There's no single best form builder app — there's the best one for where your responses need to live and how much you want to pay. Most "top 10" lists bury that in affiliate links. Here are six options compared honestly, including one that's ours (we'll say so up front), with a verdict for each and a table at the end.
1. FormMaker — best for Google Forms users on mobile
Disclosure: FormMaker is our app. It exists to solve one specific problem: Google Forms is free and excellent, but Google never built a mobile app for it, and the desktop editor is painful on a phone. FormMaker gives you a native, touch-first editor on iPhone and Android that creates and manages real Google Forms through your own Google account — same links, same response spreadsheet, nothing proprietary. You can build a form, share the link or a QR code, and view responses from your phone. It's not the right pick if you don't use Google Forms; it's the obvious pick if you do and you're on mobile.
2. Google Forms (browser) — best free option, weakest on mobile
Google Forms remains the default for a reason: it's completely free with any Google account, has no meaningful response limits, and pipes answers straight into Google Sheets. The catch on mobile is that there's no app at all — you're using forms.google.com in a browser, ideally with "request desktop site" enabled, and pinch-zooming through an interface built for a mouse. If you only ever build forms at a desk, this is all you need. If you build them on the go, it's the frustration FormMaker was built to remove.
3. Microsoft Forms — best if you live in Microsoft 365
Microsoft Forms is Google Forms' closest rival: free with a Microsoft account, more generous polish in themes, and — unlike Google — an actual mobile experience, available through the Microsoft 365 (Office) app. Responses export to Excel, quizzes work well for teachers on Microsoft-based school accounts, and integration with Teams is seamless. The reasons not to pick it are ecosystem reasons: if your collaborators, storage and spreadsheets are Google-side, Forms responses landing in Excel instead of Sheets creates friction you'll feel every week.
4. Typeform — best-looking forms, priced accordingly
Typeform's one-question-at-a-time, conversational style genuinely gets attention, and for marketing lead capture or brand-sensitive surveys it looks better than anything else here. The trade-offs are real: the free tier is tight on responses per month, paid plans cost meaningfully more than competitors, and there's no full-featured mobile app for building — it's primarily a web product. Choose Typeform when how the form feels to respondents matters more than cost; skip it for internal sign-up sheets.
5. Jotform — most features, steepest learning curve
Jotform is the power tool of this list: a huge template library, conditional logic, payment collection, e-signatures, PDF generation, and dedicated mobile apps (Jotform and Jotform Mobile Forms) that are genuinely capable, including offline data collection. The free tier is usable but capped on submissions, and the sheer number of options can feel like overkill when you just need a ten-question survey. Pick Jotform when you need forms that do things — take payments, kick off approval workflows — rather than just collect answers.
6. SurveyMonkey — best for structured research
SurveyMonkey is built for surveys specifically, not general forms: question banks, survey methodology guidance, and analysis tools that go deeper than anything Google or Microsoft offer. It has a solid mobile app for creating surveys and monitoring results. The downside is the pricing model — the free tier is restrictive (limited questions and responses per survey), and useful features sit behind plans aimed at businesses. Choose it when you're running real research and will act on the analysis; it's overpriced for an RSVP form.
