What is Trial period?

Definition, examples, and more

Definition

A limited timeframe during which users can access premium content or features for free. Typical trial durations range from 3 to 30 days. Trial design (length, gating, timing) directly impacts conversion and perceived value.

How to Calculate

Trial Impact on Revenue = Trial Starts x Conversion Rate x Monthly Price. Compare across trial lengths to find the optimal duration.

Example

A productivity app tests 3-day, 7-day, and 14-day trials. The 7-day trial achieves the highest conversion (48%) because it gives enough time to build habits without being so long users forget. The 3-day converts at 35% (too rushed), the 14-day at 42% (procrastination).

Why Trial period Matters

Trial length is one of the most impactful variables in your subscription model. A sleep app tested 7 vs 14-day trials and found the 7-day generated 20% more total subscribers — not because of higher conversion rate, but because 7-day trials started more frequently (lower commitment barrier). Getting trial length right was worth an estimated $200K in annual revenue.

Frequently Asked Questions

What is the best trial length?

7 days is the most common and often optimal for consumer apps. It provides enough time to form a habit but creates urgency. Complex tools may need 14 days. Test 3, 7, and 14-day trials for your specific app.

Should I show the trial length on the paywall?

Always. Transparency builds trust. '7-Day Free Trial, then $9.99/month' is clear and honest. Hiding the trial length or auto-renewal terms leads to refund requests and regulatory issues.

Can I offer different trial lengths to different users?

Apple allows one introductory offer per subscription group per Apple ID. However, you can use promotional offers to give different trial-like experiences to different segments. Botsi helps manage segment-specific offers.

More terms starting with “T”

Third-party billing

Payment processing handled outside of Apple or Google's in-app purchase systems. Commonly via payment platforms like Stripe, Paddle, or PayPal. Often used for web subscriptions or Android apps distributed outside the Play Store, allowing greater pricing control and lower platform fees.

Time-based offers

Promotions with a clear expiration (e.g "48-hour offer") designed to create urgency and drive faster decision-making. These are often delivered through paywalls, lifecycle campaigns, or triggered messaging tied to in-app behavior.

Time-to-first-purchase

The amount of time between a user installing the app and starting their first subscription. A key metric for measuring the effectiveness of onboarding, paywall timing, and perceived value delivery.

Tracking consent

A user's decision to allow or deny tracking (e.g., through Apple's App Tracking Transparency prompt). Consent status affects how well apps can attribute installs, personalize messaging, and optimize acquisition across marketing channels.

Trial conversion rate

The percentage of users who begin a free trial and subsequently convert to a paid subscription. This is one of the most important metrics for subscription apps with trials, reflecting onboarding success, feature adoption, and value communication.
