🔍 The #1 refund mistake that keeps charging your card (revealed near the end)
Most fasting apps give you 7 days to decide. Fastic gives you 14 and calls it the Feel Good Guarantee. A 2022 cross-sectional survey found that lack of motivation and perceived lack of usefulness are the two primary reasons people abandon mHealth apps (PMC). As a NutriScan nutritionist, I think longer trial windows help people give a new habit a fair chance before walking away. In this guide, I will explain exactly how the Fastic trial works, what the refund covers, and how to cancel on every platform so you never pay for something you do not want.
Getting your money back should always feel this good
What Is the Feel Good Guarantee?
Fastic's Feel Good Guarantee is a voluntary money-back promise that goes beyond the standard app store refund window. Here is what the official guarantee page says:
- You can try Fastic Plus completely free for 14 days
- If you decide it is not for you, Fastic refunds the full amount
- No deductions whatsoever, even though digital products normally allow deductions
- No usage requirements at all
Key Takeaway
Your personal impression is enough. If you simply do not like the app, that counts. You do not need to follow a fasting plan, use the timer, update your weight, or achieve any specific results.
How Is This Different From a Normal Free Trial?
Most fasting and nutrition apps offer a 7-day free trial. You sign up, enter payment info, and get charged automatically on day 8 unless you cancel. The Fastic model works differently.
| Feature | Standard 7-Day Trial | Fastic Feel Good Guarantee |
|---|---|---|
| Trial length | 7 days | 14 days |
| Payment at signup | Yes (charged after trial) | Yes (charged immediately) |
| How to get money back | Cancel before trial ends | Request refund within 14 days |
| Usage requirements | None | None |
| Refund deductions | Varies by platform | Zero - Fastic waives deductions |
| Who processes refund | App store | Fastic directly (or app store) |
The key difference: with a standard trial, you avoid a charge by canceling early. With the Feel Good Guarantee, you pay upfront and request a refund if unsatisfied. This means you need to take action to get your money back.
Important
The refund is not automatic. You must actively request it within 14 days. Set a calendar reminder so you do not miss the window.

How Much Does Fastic Plus Cost?
Before you start a trial, it helps to know what you are signing up to pay. Fastic Plus has multiple pricing tiers on the App Store:
| Plan | Price | Per Month |
|---|---|---|
| 1 month | $11.99 - $14.99 | $11.99 - $14.99 |
| 3 months | $27.99 - $29.99 | $9.33 - $10.00 |
| 12 months | $74.99 - $79.99 | $6.25 - $6.67 |
Prices vary because Fastic runs promotional pricing. The app may show you a different price during onboarding depending on your location and the current offer. A third-party review by Health Insider (written by Dr. Alexandra Pierce, MD) confirmed the base pricing at $11.99/month.
Fastic has 246K ratings on the App Store with a 4.8/5 average and over 20 million downloads worldwide.

Step-by-Step: How to Use the Feel Good Guarantee
Here is exactly how to try Fastic risk-free and get a refund if it does not work for you.
Step 1: Download and Subscribe
- Download Fastic from the App Store or Google Play
- Complete the onboarding quiz (age, weight, goals, preferred fasting schedule)
- Choose a subscription plan - payment is taken immediately
- Note the exact date you subscribed
Step 2: Try the App for Up to 14 Days

- Fastic Academy courses on nutrition and fasting
- Daily and weekly challenges
- AI-powered food scanner
- Protein Fasting mode, backed by a clinical study showing that intermittent fasting combined with high-protein nutrition produces greater fat loss and better muscle retention than calorie restriction alone (PMC)
Step 3: Decide Before Day 14
If you want to keep Fastic Plus, do nothing. Your subscription continues.
If you want a refund, you need to request it before the 14-day window closes. The method depends on where you purchased.

- Fastic processes the refund directly
According to Fastic's help center, the support team handles website purchase refunds via email.
Step 5: Cancel Your Subscription

Three simple steps: open settings, find subscriptions, tap cancel
Cancel on iPhone:

⏳ The #1 refund mistake (next)
The EU Withdrawal Right: Your Extra Layer of Protection
Fastic GmbH is a German company based in Berlin (Pappelallee 78/79, 10437 Berlin). This means EU consumer protection rules apply. According to Fastic's cancellation policy:
- You have a 14-day right of withdrawal from the date of purchase
- No reason is required
- You can withdraw by sending a clear statement via email ([email protected]) or letter
- Fastic must refund all payments within 14 days of receiving your withdrawal notice
- The refund uses the same payment method as the original transaction
- No fees are charged for the refund
If you started using the service during the withdrawal period, you may need to pay a proportional amount for the services already used. However, the Feel Good Guarantee explicitly waives this, "no deductions whatsoever."
Double Protection
You effectively have two overlapping protections: the Feel Good Guarantee (voluntary) and the EU withdrawal right (legal). Both give you 14 days.

7 Tips to Get the Most From Your 14-Day Trial
1. Set a Calendar Reminder on Day 10
The 14-day window passes quickly. Set a reminder 4 days before it ends so you have time to decide without rushing.
2. Screenshot Your Purchase Confirmation
Save the receipt or confirmation email from Apple, Google, or Fastic. You will need it if you request a refund, especially for website purchases.
3. Try at Least Two Fasting Schedules
Fastic supports multiple patterns: 16:8, 14:10, 18:6, and more. If one feels too hard, switch before giving up on the whole app.
4. Open the Academy Section
Many users skip the educational content. The Fastic Academy has courses on fasting science, protein fasting, and habit building. These are Plus-exclusive features worth trying before you decide.
5. Test the Food Scanner
Snap a photo of your meal to see calorie and nutrient estimates. This feature helps you understand what you are eating during your feeding window. If you want to compare food scanning accuracy across apps, NutriScan's AI-powered scanner uses advanced image recognition to identify individual ingredients in mixed meals.

6. The #1 Refund Mistake: Do Not Just Delete the App
You have been patient. Here is the mistake that costs Fastic users the most money.
Uninstalling Fastic does not cancel your subscription or trigger a refund. You must cancel through your device settings or the Fastic website. A 2021 study on mHealth engagement found that many users abandon apps without formally canceling, leading to unwanted charges (PMC). Many people assume deleting an app stops the billing. It does not. Your subscription lives in your Apple ID or Google account, not on your phone. Delete the app and you lose access to the features, but the charges keep coming every month or year until you actively cancel.
7. Contact Support Early if Unsure
If you are on the fence at day 10, email [email protected]. The support team can answer questions about features you have not explored yet.

What Real Users Say About the Refund Process
Fastic has 5,280+ reviews on Trustpilot and 246K ratings on the App Store (4.8/5). User experiences with the refund process vary by platform:
Positive experiences:
- Users who purchased on the website report smooth refunds when they email [email protected] within 14 days
- The Feel Good Guarantee is praised for having no usage conditions
- One App Store reviewer noted getting a full year of Plus on sale for about $24, calling it "a really good price"
Common complaints:
- Some users do not realize that deleting the app does not cancel the subscription
- A few users report difficulty finding the cancel button within the app itself
- App Store and Google Play refund timelines depend on each platform, not Fastic
How to Check Where You Purchased Fastic
If you cannot remember where you purchased Fastic, check your bank statement. Look for:
- APPLE.COM/BILL - purchased through App Store
- GOOGLE*FASTIC - purchased through Google Play
- FASTIC GMBH or similar - purchased directly on fastic.com
How Fastic's Guarantee Compares to Other Apps
| App | Trial Length | Refund Policy | Usage Requirements |
|---|---|---|---|
| Fastic | 14 days | Full refund, no deductions | None |
| MyFitnessPal | 7 days | Cancel before trial ends | None |
| Lose It | 7 days | Cancel before trial ends | None |
| YAZIO | 7 days (website only) | EU 14-day withdrawal | None |
| Simple | No free trial | Platform-dependent | N/A |
| MacroFactor | 7 days | 60-day refund via support | None |
| NutriScan | 7 days | Cancel before trial ends | None |
Fastic's 14-day window with explicit no-deduction refund is the most generous standard trial among major fasting and nutrition apps. MacroFactor offers a longer refund window (60 days), but you have to contact support and it is not prominently advertised.
Figure 1: Fastic offers double the trial length of most competing fasting and nutrition apps
A 2021 systematic review found that smartphone-based health interventions show significant promise for reducing body weight and blood pressure in adults, but engagement drops sharply after the first week (PMC). A 14-day trial gives users a better chance to form initial habits before the early dropout period ends.

What Happens After the Trial?
If you keep Fastic Plus after 14 days, your subscription auto-renews based on your chosen plan:
- Monthly: Renews every 30 days
- 3-month: Renews every 90 days
- Annual: Renews every 365 days
Auto-renewal charges within 24 hours before the current period ends. To stop renewal, cancel at least 24 hours before the next billing date.
If you cancel but your current period has not ended, you keep access to Plus features until the period expires. Fastic does not cut off access the moment you cancel. You get what you paid for.
After your subscription expires, your account reverts to the free tier. You keep:
- Basic fasting timer
- Step counter
- Water tracker
- Body status tracking
You lose:
- 4,500+ recipes
- Academy courses
- Daily and weekly challenges
- Fasting Buddies connections
- AI food scanner (full version)
- Personalized daily plans
Research: Why Trial Length Matters for Fasting Apps
Intermittent fasting is not something you can evaluate in 3 days. Your body takes time to adjust to new eating patterns. Research supports giving yourself at least 2 weeks:
- A clinical study on protein fasting found that intermittent fasting combined with high-protein nutrition leads to significantly greater fat loss and better muscle retention than calorie restriction, even with equal calorie intake (PMC). These results took weeks to appear.
- A 2021 review of nutrition and weight management found that sustainable dietary changes require consistent tracking and support over time, not quick fixes (PMC).
- A 2022 cross-sectional survey of mHealth app users found that perceived usefulness is the strongest predictor of continued use, but users need enough time to discover all features (PMC).
This is why Fastic's 14-day window makes practical sense. It gives you enough time to try different fasting schedules, explore recipes, and see if the tracking tools fit your routine. If you are exploring intermittent fasting approaches, having two full weeks to experiment with different patterns can make a real difference in your experience. For a data-driven approach to your nutrition during fasting windows, check out NutriScan's meal scanning guide and our personalized diet plan feature.

Conclusion
The Fastic Feel Good Guarantee gives you 14 days to try Fastic Plus with zero risk. No usage requirements, no deductions, and a full refund if you email within the window. EU withdrawal rights add a legal safety net on top of the voluntary guarantee.
The most important thing to remember: you must take action to get a refund. It is not automatic. Set a reminder, save your receipt, and cancel your subscription separately from requesting a refund.
If you are exploring fasting apps and want to compare options, track your meals and fasting patterns with NutriScan to see how different eating schedules affect your nutrition. Our macro calculator can help you plan a sustainable eating strategy that complements your fasting routine.
Frequently Asked Questions
Does Fastic charge you upfront or after the trial?
Fastic charges you at the time of purchase. Unlike apps with a free trial where you are charged only if you forget to cancel, Fastic takes payment immediately. The Feel Good Guarantee lets you request a full refund within 14 days if you are not satisfied.
Do I need to use the app a certain number of times to qualify for the refund?
No. The Feel Good Guarantee explicitly states that no usage requirements apply. You do not need to follow a fasting plan, use the timer, update your weight, or achieve any results. Your personal impression is enough.
What if I bought Fastic through the App Store - does the guarantee still apply?
Yes, but the refund process goes through Apple, not Fastic. Go to reportaproblem.apple.com to request a refund. Apple reviews refund requests on a case-by-case basis. For the strongest case, request within 14 days and mention the Feel Good Guarantee.
Can I cancel and still use Fastic Plus until my current period ends?
Yes. When you cancel a subscription, Fastic does not cut off access immediately. You keep Plus features until the current billing period expires. After that, your account goes back to the free version with basic features.
What is the difference between the Feel Good Guarantee and the EU withdrawal right?
The Feel Good Guarantee is Fastic's voluntary promise, a full refund with no deductions and no usage requirements. The EU withdrawal right is a legal right for all consumers purchasing from EU-based companies (Fastic GmbH is in Berlin). Both give you 14 days, but the EU right may require you to pay for services already used. The Feel Good Guarantee waives that.
How long does the refund take to process?
For website purchases, Fastic processes refunds after you email [email protected]. For App Store purchases, Apple typically processes refunds within 5-10 business days. For Google Play, refunds usually appear within 1-4 business days. The exact timeline depends on your bank and payment method.
Is there a way to extend the trial beyond 14 days?
No. The 14-day Feel Good Guarantee is a fixed window. If you need more time to decide, consider starting with the free version of Fastic (which includes the basic fasting timer, step counter, and water tracker) and upgrading to Plus only when you are ready to commit.
