Helped me see what’s visible and helped me find them. Love using it with the family! ### 4/5 — Fun App *2026-05-25, version 1.9.1* it’s getting better ! ### 5/5 — Enjoying Easy Astronomy *2026-05-25* I got the Gravity app along with my Hestia telescope. It really has made backyard astronomy super easy. The app has some really cool tricks for locating stars and when using it to take photos it already flips and rotates object like the moon and sun into the correct position. I think they are really have a good app and it’s a great start. I’m looking forward to see what upgrades and improvements they make in the future. ### 5/5 — Love it. *2026-05-24* I have the Vaonis Hestia - not their most powerful telescope, I love it. The Gravity App, once you really give it a chance & spend some time with it, is great. User friendly interface & does just what I want, without annoying pop ups or steps! ### 5/5 — Great *2026-05-24, version 1.9.1* Great improvement!! ### 2/5 — So disappointed *2026-05-24, version 1.9.1* I bought this because it was supposed to be user friendly. I managed to get a close shot of the moon after a lot of finagling. But the app doesn’t locate anything. I tried to get help but they have the worst customer service. :( ### 5/5 — Works as it should! *2026-05-24* Works great with my Hestia telescope! Updates consistently improve the apps functionality! ### 5/5 — Super app pour se lancer dans l’astro *2026-05-22* Je l’ai acheté pour mon neveu de 8 ans et je suis ravi de ce cadeau!! ### 5/5 — Application indispensable *2026-05-21* Belle application indispensable pour exploiter au mieux le mini télescope Hestia. Je ne manque plus une occasion de photographier le ciel dès que possible. Pour moi, il manque quand même 2 options à rajouter : - La possibilité d’utiliser le téléobjectif de l’iPhone. - La possibilité de déclencher la photo sans toucher liPhone avec une Apple Watch par exemple. ### 5/5 — Merci pour la mise à jour ! *2026-05-20* Un outil ludique pour photographier la lune et le soleil.
