User Reviews

User sentiment is mixed: Kilnotes is praised as a strong, school-focused note-taker that's easy to use and visually appealing, with a rich feature set available without mandatory upgrades. However, complaints center on ads interrupting usage, stability issues causing crashes and lost progress, and dissatisfaction with pricing and subscription policies, including revoked permanent access and feature limits behind paywalls.

Pros

Great for students; enhances productivity and organization.
Easy to understand and use with intuitive icons.
Feature-rich with templates and options; many reviewers say it has everything they need.
Aesthetically pleasing UI and well-organized notes.
Many features available for free; not all users need to subscribe.

Cons

Intrusive ads disrupt the experience; some users even try to disable Wi-Fi to avoid them.
Frequent crashes and instability; progress is not reliably saved.
Pricing and subscription concerns; revocation of permanent membership and limits on notes behind a paywall.

I loved the app, after I bought premium many of the page options got paywalled and just completely disappeared. I wanted to use them. 😫😢

Apparently, you now have to pay for stickers, even if you have premium? Stickers used to be included a month ago? I’ve been using kilonotes for over two years now and have loved it, but this is seriously affecting my experience.
