Review summary

Users acknowledge some potential and have had brief positive impressions (good, very good, excellent, love it, promising), but the dominant sentiment is frustration with the app’s monetization model and reliability. Many reviews complain that the app can't be used without paying, with multiple mentions of forced trials, misleading free labeling, and unexpected charges. Billing and refund issues are also common. Onboarding and UI bugs disrupt setup, and several users report crashes, non-loading features, and cross-device sync problems. Overall, paywall and stability issues deter adoption, with calls for better support and more useful content.

Pros

it's good
love it
excellent
very good
seem very promising

Cons

Paywall: requires payment to use; no real free version
Billing and refund problems: unauthorized charges and difficulties with refunds
Onboarding and UI bugs: forced rating to use the app and white-on-white setup issues
App stability issues: crashes, app not opening, and features not loading
Limited features relative to price: offers little and feels not worth paying

2026-08-19	Al*****	Incredibly annoying and useless app, way too expensive for what it offers and there is no free version. Downloaded and payed because it is supposed to be better than flo, but it is much worse, also if you change your device, even though you have an inn-app account, you have to scan a qr code on the other device, WHICH IS IMPOSSIBLE IF THE OTHER DEVICE IS BROKEN, which means if you payed for a whole year you lose the membership. Horrible experience

2026-08-02	Ma*****	unfortunately can't get access until I agree to a subscription, I thought the app would be free. dissapointing to see there wasn't even an option to select to use the app for free.
