Fi Referral Program: €20 Off + 1 Free Month (2026)

Existing Fi members can find their unique code or QR in the Fi app and share it directly with a friend. The friend must enter the code during checkout for a new full-price Series 3+ or Fi Mini. The €20 discount is applied at purchase; membership rewards depend on tracker activation and membership timing.

The referred friend receives €20 off the eligible tracker purchase and one free month added to Fi Membership. The referrer receives one free membership month. Fi says the friend’s free month is added after the tracker is activated and the applicable six-month commitment is completed; the referrer’s month applies at the end of the current membership term or after completing that commitment.

1. 1

   Open Referrals in the Fi app

   Find your unique referral code or QR code and share it directly.

2. 2

   Buy an eligible new tracker

   The friend chooses a new full-price Series 3+ or Fi Mini from Fi’s shop.

3. 3

   Enter the code at checkout

   The referral must be applied during checkout; Fi does not add codes retroactively.

4. 4

   Activate the tracker

   Activation is required for the membership rewards.

5. 5

   Wait for membership credit

   The free month is applied according to Fi’s membership and commitment timing.

Yes. Fi now has a Spanish-language referral help page quoting the reward in euros, and its European help page lists €20 among the local rewards. This guide covers that European offer; US terms and dollar pricing can differ.

Fi does not state a fixed program end date on the current European referral page. Because the help article was materially updated on September 17, 2026, use the current checkout and official help rather than older posts.

The €20 discount is applied when the valid code is entered at checkout. After activation, the friend’s free month is added after completing the six-month commitment; the referrer receives an email and the free month applies at the end of the current membership term or after completing the six-month commitment.

• The purchase must be a new, full-price Series 3+ or Fi Mini from Fi’s official shop.
• The code must be entered at checkout and cannot be added after purchase.
• Referral codes cannot be combined with other coupons.
• Codes do not apply to accessories or standalone Fi Memberships.
• Referrals from the same household may be revoked.
• Fi explicitly says codes posted on external websites may be revoked, so public coupon/referral-site sharing carries a real eligibility risk.
• Bonuses cannot be earned on gifts bought by the referred person for the referrer.
• Each code can be used once per unique person and each account is capped at 12 referrals.

For someone already planning to buy an eligible Fi tracker, €20 off plus a free membership month is a concrete saving. The main caveat for ReferTree users is Fi’s explicit warning that codes posted on external websites may be revoked, so the safest use is direct person-to-person sharing rather than public distribution.
