Peekaboo - I see you!
It's time to meet adorable new animal friends on our trip to the seaside.

### 5/5 — Amazing!

*2020-05-26*

My little one loves all of the apps by the developer. These have wonderful graphics and catchy music! Your kid will have so much fun!!

### 4/5 — hübsch für die Kleinen, aber...

*2020-05-25*

Inhalt: 15 grafisch ansprechend dargestellte Meerestiere. Die Interaktion hält sich in Grenzen.
Die Menüsprache ist von vornherein deutsch, jedoch muss man in den Einstellungen noch einmal deutsch als Sprache auswählen, damit die Tiernamen deutsch ausgesprochen werden.
Sehr nervig: falsche Bildschirmorientierung auf dem iPad, alles steht auf dem Kopf. Je nachdem, welches Case man am iPad angebracht hat, ist eine sinnvolle Nutzung der App dadurch kaum möglich :(

### 3/5 — Mixed feelings

*2016-09-21*

There are some glaring bugs in this app, particularly, there is a whale that's just cut in half... The app is a fun idea, but it is very limited and once you've gone through all the animals once, that's about it. There is no mixing things up or exploring/interacting with the animals in a different way. You touch the screen and the animals appear exactly the same way every time. I guess it is interesting to toddlers, but I imagine even they might get bored with it. I expected something a bit more for the cost.

### 2/5 — Buggy like all tbd products

*2015-12-10*

Amateur programmers that don't test their products before taking your money.  For example after touching the screen the whale descends from top to bottom with half its body missing on the left.  Then after it finishes descending the body appears.  And Pelican and Stingrays doesn't repeat how to say them when you touch the word (disappointing for a child learning words).  Similarly Sea Lions seems to repeat the word if you press after the printed word and Seahorses only repeats if you press 'Sea' but not anywhere else in the word.  All stuff that programmers that care about their work could have easily found and fixed.

### 3/5 — For $2.99 there needs to be more animals

*2014-10-06*

For $2.99 there needs to be more animals. This app could be GREAT, but my toddlers go thru it fast. (Oh, and the "touch it" animation could be more interactive.) 3 Stars.

### 5/5 — Fun app

*2014-06-07*

My 2 year old loves this app!

### 3/5 — Cute but..

*2014-05-18*

This app is pretty boring for a toddler who likes interactive apps, not much to do besides hit the forward or back button.

### 3/5 — Ok

*2014-04-29*

very basic. probably more suited to under 3years

### 5/5 — Great for toddlers

*2014-04-12*

We bought this app after using the "egg head" app from this creator. Great transitional app- featuring some of the same animals so our 23 month old son recognizes them but they include the animal body not just the head! This app is super cute and interactive- which is helping our son with using his fingers on the touch screen. Sounds are great, colors are great. Love love these apps.

### 5/5 — Love the multi lingual options!!

*2014-04-12*

Was just looking for more French and Spanish speaking apps for my son!!
