500 users in 80 days, first review & new version

Yesterday we reached a supercool milestone: up to now 500 people paid us real money for our app to document their baby's teeth – that's unbelievable! We're so grateful for the trust they have in our work and that we have a valuable impact on people's lives!

We even got the first review in the App Store: 4 out of 5 stars, since we messed up the dates (didn't account for the day-month switch in US) but they're overall very happy with the app. That this person got out of their way and went into the App Store to write this review (we don't have a "Rate this app" popup in the app) is especially flattering!

Last week two persons wrote us about the exact same feature-wish they had: the possibility to change the orientation of the teeth' labels (dentists switch left and right). With the new update, released yesterday, we addressed that with a new settings screen that can be accessed with a simple swipe.

This is also the base for the next feature, which the most people asked for: being able to add multiple children. It's a testimonial for starting out super small, that such a non-brainer feature was not part of the 1.0 release and the app is still successful (and people are using it regularly).

In total we've made $542 which makes $375 in revenue after Apple's cut. The sales chart is very consistent and people regularly buy the app, with the exception of two crazy high spikes (71 and 54 sales in a single day) and I have no clue why they happened. We didn't do any marketing yet, there's no feature in the App Store and I can't find anybody online who may linked to our app...
