Bova Buddy
Read full descriptionHide full description
It has opinions. Bova Buddy is a virtual pet game where your pet is a rock. Swipe to pet it, earn its trust, unlock its moods and sarcastic remarks — and watch a stone slowly learn to like you. No ads, no accounts, plays offline. KEY FEATURES - Pet the Rock: Swipe to pet it. Longer strokes build more trust. Tap it or shake your phone and it reacts — but don't overdo it, or it gets offended for a moment. - 4 Relationship Levels: Go from Suspicious Mineral to Familiar Boulder, Stone Companion and finally Kindred Rock. Every level changes its face, mood and what it says to you. - Cracks & Life Cycle: Each level leaves a crack. At 100% the rock splits, your "rocks broken" counter goes up, and a new rock arrives to start over. - Rare Events: A 5% chance after every pet — critical pet, sneeze, identity crisis, a 3-second nap or a perfect swipe, with banners, sparks and haptics. - Coins & 19 Skins: Every pet earns a coin; level-ups and broken rocks earn more. Spend them on pirate, astronaut, knight, samurai, punk, Midas and more. Each skin changes both the rock and the world around it. - Stats Screen: Trust, level, mood, total pets, rocks broken, days together, daily average, coins earned and spent, unlocked skins and milestones. - Daily Visits: Check in every day for +1 trust and a growing "days together" streak. - Reminders: An evening nudge at 7 p.m. with a line from your rock, and a gentle reminder if you've been away for 3 days. HOW IT WORKS 1. Meet your rock. 2. Swipe to pet it and earn trust. 3. Unlock moods, phrases and skins. 4. Reach 100%, say goodbye, adopt the next one. MADE FOR SHORT BREAKS System, Light and Dark themes. Sound and haptics you can turn off. Reset the relationship anytime — the rock will remember that.

Spend quiet days with your fish in a little aquarium. Pasterium C is a 3D aquarium set in a softly muted pastel room, where you enjoy everyday life with your fish. You start with three little fish in a fishbowl. Give them names, feed them, and watch them slowly grow and bond with you. - Every fish has its own personality and looks Even fish of the same kind each have something special. Keep an eye on growth, bond, and health on each fish’s card. Fish that feel weak can get care, or rest at boarding. - A life that grows a little every day New friends and ornaments arrive, and sometimes eggs are laid. On day 7 the living room tank opens, and on day 14 you get an auto feeder you can use in any tank. - Make the tank your own Choose plants, ornaments, sand colors, and lighting to decorate. Save up to 5 favorite layouts for each tank. - Learn about creatures and ornaments in your journal Look back on each day in the diary, and read about each one in the creature and ornament guides. - Shifting light and gentle sounds The light in the room changes from morning to night and with the seasons. Watch your fish from underwater, and keep photos or short videos. Choose between the original music and lofi, with different tracks for morning, day, and night. You can choose your tap sounds too. - Start for free, then visit the study The fishbowl and the living room are free. “Study with a Bookshelf” is a one-time in-app purchase. It adds a big tank about 120 cm wide, along with Discus, Arowana, River Stingray, and Axolotl. Available in Japanese, English, Korean, Arabic, Simplified and Traditional Chinese, Spanish, French, German, and Portuguese. No ads and no account sign-up. Everyday play works offline. Buying and restoring the in-app purchase needs a connection. Your fish, diary, and other records are saved in the app. Deleting the app also deletes these records, but photos and videos you saved to the Photos app remain.

Verdict
The clearest difference is in-app purchases: Bova Buddy at none against Pasterium C's 1. Pasterium C's advantage is update cadence (every 5 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
