"WatchieBesti is such a delightful addition to my Apple Watch! I especially enjoy the Plants Kingdom and how the characters and their environments change throughout the day. It's a creative and engaging way to incorporate activity into everyday life. What makes the experience even better is the developer's responsiveness. I reached out with a suggestion for a new complication design, and Mike thoughtfully explored the idea and is already incorporating it into an upcoming update. It's refreshing to see an independent developer so genuinely invested in the app and its users. Looking forward to seeing how WatchieBesti continues to grow!"— App Store review
"I've tried quite a few apps like this one, but this one intrigues me — because of how it evolves. I don't think we'll get stuck in monotony. It's a pretty complete app and easy to understand. I'd encourage you to keep refining it — it has real potential."— App Store review, France (translated from French)
