Gummble Ads

Mobile app promo video templates

Four structures that keep appearing in app ads that run for months. Timing per beat, where the caption goes, and which verified example to study.

Problem → solution demo (15 s)

Best for: Utility, health, finance apps with one clear job.

TimeBeat
0–2 sThe problem, as a typed or spoken line ('I keep forgetting my meds').
2–5 sApp opens on the outcome screen (the finished state).
5–12 sThree taps that get there, each with a two-word caption.
12–15 sOutcome again + store CTA.

Feature spotlight (10–12 s)

Best for: Existing apps launching one feature; retargeting.

TimeBeat
0–1 sFeature name on screen, phone centred on a flat gradient.
1–8 sOnly that feature, mocked at 1.3× zoom so text reads at feed size.
8–12 sOne-line benefit + CTA.

UGC review (20–30 s)

Best for: Consumer apps where trust is the objection.

TimeBeat
0–2 sCreator face, question hook ('is this the easiest way to…?').
2–6 sThe objection, said out loud.
6–20 sHand-held phone + screen recording answering it.
20–30 sVerdict, soft CTA ('link in bio' / store name).

Not in the editor: it needs a person on camera. Film it yourself; the timing above still applies.

Before / after (8–10 s)

Best for: Editing, cleaning, planning, any visible transformation.

TimeBeat
0–2 s'Before' held for a full second with a caption.
2–7 sThe in-app action, sped up 1.5–2×.
7–10 s'After' + CTA.

Questions

How long should a mobile app promo video be?

For paid social, 8–15 seconds carries most of the value; UGC-style reviews can run 20–30 seconds because the talking head holds attention. App Store and Play previews have their own rules (iOS 15–30 s, Play 30 s to 2 min) and are not ads.

Where do captions go?

In the middle band of the frame, inside every platform's safe zone. Check placement with the safe-zone checker; the default bottom position in most caption tools is covered on TikTok and Reels.

Do I need a voice-over?

Most viewers watch muted at first. Captions carry the message; a voice-over helps the UGC format and is optional for demos.

Can I get these as editable files?

The structures are free to use. Three of them open in the app demo video maker as editable projects on your own screen recording; export an MP4, change a word, export again. The UGC review needs a person on camera, which the editor doesn't make.
