I have been promoting products through Stack Influence for 7 months now and have been BLOWN away by how fun and professional they are to work with. They have multiple products you get to pick from. You first have to purchase the item yourself, then there are requirements that must be met to receive your payout. Examples are: you have to show your face with the product, you have to do it within a timeline, you have to include certain hashtags, etc. Once you do all the requirements you “Submit your Post” and they send the money to your PayPal account. I have received every payout!! It’s all very simple and thoroughly explained.” BECOME A STACK INFLUENCER TODAY: Don’t miss out on the opportunity to elevate your influenster potential.

Verdict

The call

The clearest difference is monetization model: Stack Influence at free against Littlebird Safety Tracker's free with in-app purchases. Stack Influence also leads on ratings volume (400 vs 36) and iOS requirement (15.0 vs 26.0). Littlebird Safety Tracker's advantage is update cadence (weekly vs monthly) and rating (4.6 vs 4.3). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Littlebird Safety Tracker holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Stack Influence has 400 ratings behind it against 36, so its average is the more settled of the two. Written reviews complicate that: 78% of Stack Influence's written reviews are positive against 75% of Littlebird Safety Tracker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Stack Influence ships an update monthly, Littlebird Safety Tracker weekly. The most recent releases landed on October 27, 2026 and October 25, 2026 respectively.
