Thank you very much.

Koi Habit Tracker

I absolutely adore this app! It helps me to create habits and I personally log my to-do list as goals to help push me further.

Thank you very much for the review! Glad Koi is helping.

Surprisingly effective!

Surprisingly accessible with VoiceOver on the iPhone for the blind. There are a few things that can't be done with this screen reader, but it's still very playable. I enjoy the fact that it's not just a habit or goals tracker app, but that there is an additional satisfaction of collecting Koi and naming them.

Pleased Koi is helping!

:(

was 5 stars before but now after the 1.17.10 update the app crashes after being open for a few seconds. please fix ❤️‍🩹 maybe it has something to do with Me being on an iphone 7. I don’t have a way to get a better phone right now. thankfully I have another broken phone though this app works 5 stars on and I left Y’all a 5 star review on google play. I hope to be able to update this review to be better soon. or delete it. I just wanted Y’all to know what was going on so it could hopefully get fixed. I love this app thank Y’all 🤍
